For the majority of Toyota Motor Co. vehicles, the requirement is simple. Hold the Smart Key fob against the Start / Stop 
ignition button with the Toyota, Scion or Lexus logo facing the button or switch. Press the Start / Stop button, keeping the brake pedal depressed. You can even press the button with the fob itself.
In truth, a buzzer will sound when the fob is touched to the Start / Stop button. If the button is pressed within five seconds of the buzzer sounding, the vehicle will start, assuming the brake pedal remains depressed.
The new (2020) Toyota Supra is an exception. There is an image of a key with lines radiating from it on the side of the steering column. Hold the back of the remote control (NOT the tip like the image) against the marked area on the steering column and press the Start/Stop button within 10 seconds while depressing the brake.
Another exception is the Toyota Prius in the 2004 through 2009 model years. These cars have a slot beneath the Start/Stop button that will accept the key fob. Insert the fob, buttons up, then press the Start/Stop button while depressing the brake pedal as normal.
A final exception (right) is found in early Lexus LS models. It uses a key fob with a tapered end and a start cylinder that is turned to start the car. In this case, the taped end of the fob is inserted into the start cylinder. The car will recognize the key fob, which can then be used to turn the cylinder.
Note: If you have made an attempt to start the vehicle without success, there may be residual pressure in the brake system and a new warning light may appear (left) or text 
message to Step on the Brake. Press the brake pedal very, very hard when trying to start the vehicle again to be sure that the release switch behind the pedal is engaged. Or wait a few minutes and try again.

Here’s the deal: Buckle up, find your model, and if your start battery is still good, we’ll get you underway. Note that they are generally presented as sedans, then SUVs then pick ups.
In Corvette models built before 2014 (C6), the pocket is on the left of the inside of the glove box. Place the transmitter in the pocket with the buttons facing the glove box storage area (right). Then, with the vehicle in P (Park) or N (Neutral), press the brake pedal and the Start / Stop ignition button as normal.

Push button or keyless start is introduced to the Camaro in 2016. It also uses the cup holder as a back up slot, but to their credit, Chevrolet made this one simple. Make sure there is nothing, particularly coins, in the rear cup holder, and simply drop the fob into it. The car will recognize the key and a press of the brake pedal and Start / Stop ignition button will have you on your way. Corvettes (C8), 2020 – 2023, use this spot as well. In 2024, the Corvette spot is moved to the front cup holder.
The Impala uses a back up pocket located in the front of the center console (right). The model is using the flip key thus far through 2018. Drop transmitter into the pocket with the key ring up and the buttons facing out. With the vehicle in Park or Neutral, press the brake pedal and the Start / Stop ignition button as normal.
storage area located above the infotainment screen and remove the rubber mat. Extend the key blade and place the blade into the slot (right).
moved to the center console, as shown. The rubber mat at the bottom of the console will need to be removed, and so anything actually in the console.
The last flip key back-up start option belongs to the Cruze. You must remove the plastic trim piece from the small storage area next to the accessory power outlet near the front of the console. Extend the key blade and insert it into the transmitter slot (right). With the vehicle in Park or Neutral, press the brake pedal and the Start / Stop ignition button as normal.
The 2017 Cruze gets the new key and a new back up location, which is the front cup holder, as seen to the right. Sonic, Equinox and Blazer models now use this spot as well.
The 2024 Blazer Electric Vehicle (EV) is a different animal. Its back up spot is at the bottom of the center console storage area. Drop the key fob on the spot shown (right) with the buttons up.
The Trax, which first saw push button start in 2017, also uses the front cup holder as its back up slot. However, there are three cup holders in the center console area, with the front one being separated from the two behind it. Be sure to use the one in the very front. See the image to right.
The new Trailblazer model has the back up pocket in front of the center console storage area and behind the the two cup holders on the console (image at right). Drop the key fob into the pocket or depression, The manual states that the buttons should be facing the front, but we don’t believe this is possible given the shape of the pocket. We also believe that it will not likely matter. With the vehicle in Park or Neutral, press the brake pedal and the Start / Stop ignition button as normal.
pocket also located in the face of the front of the inside of the center console. However, the pocket points down, as shown to the right. Slide the transmitter into the pocket with the key ring facing out, buttons forward (in the Suburban we had on hand, the engine started with the buttons facing either way). It is a loose fit, so don’t be concerned. With the vehicle in Park or Neutral, press the brake pedal and the Start / Stop ignition button as normal. Check out the video 
In the Chevrolet Traverse, through 2023, the transmitter pocket is at the bottom of the center console storage area, as seen in the image to the right. The outline of the transmitter will be visible to the front of the console. The 2024 Traverse uses the left or driver’s side cup holder, exactly like the Silverado EV below. Once the fob is in place, press the brake pedal and the Start / Stop ignition button as normal to start the vehicle.
shown in the manual. There are three storage spots in the console (see the red arrows), and one of them will be the “pocket” but none of them are actually marked. Drop the transmitter or key fob in the front storage spot first and attempt to start the car normally, with your foot on the brake and pressing the Start / Stop button.
In the Silverado pick up (note that the electric version is discussed below) and the Malibu sedan, the pocket for the transmitter is located in the face of the rear of the inside of the center console. Silverado gets push button start for the first time in 2019. Slide the transmitter into the pocket with the key ring facing up, and the buttons out (or however it will fit!).
the Start / Stop ignition button as normal. The pocket in 2021 Tahoe and Suburban models with a bench seat is also moved to this location, at the back of the console.
transmitter into the left side cup holder (second image below right).
First a word of caution concerning the Ford GT. Its latches are entirely electronic, the result being that, in the event of a power failure while inside the car, a back up plan is necessary. There is a strap on each pillar alongside each seat, as seen n the image to the right. Pull it to release the door.
In the Taurus, Expedition (before 2018) and Flex the Intelligent Access key slot is to the rear or the side of the console and points up. The key is slipped in vertically or horizontally depending on the slot’s shape, with the buttons facing out, as in the image shown. After inserting the key, use the Start / Stop ignition button and brake pedal to start your vehicle as usual. If it fails to start, turn the fob so that the buttons face back and try again. Once the vehicle is started, the key can be removed from the backup slot, if you wish.
In the updated (2018) Expedition, the back up slot is in the front cup holder. There is a two-piece mat at the bottom, and the front piece needs to be pulled away. It is a loose fit and slips out easily. Drop the key fob into the slot with the buttons facing the back of the vehicle and start it as normal.
New in 2019, the Transit Connect uses push button start for the first time. The back up slot is also in the cup holder. The rubber mat at the bottom of the cup holders needs to be removed and Ford recommends removing the mechanical key as well. Lay the key fob in the front cup holder with the buttons facing up and the unlock button towards the front of the vehicle. Step on the brake and start the vehicle as normal using the Start / Stop button.
The new Ranger compact pick up also uses a cup holder, the rear one. Place the key fob in the cup holder making sure that it is centered and is parallel to the brake handle, as can be seen in the image at right. The truck can then be started by stepping on the brake and using the Start / Stop button as normal.
In Explorer and Fusion models, the slot is found near the Auxiliary, USB and power ports in the center console, like the one shown. The Intelligent Access key is slipped in with the buttons facing out (in the Explorer we had, the vehicle started with the buttons facing either direction) and the key ring up.
The Edge back up slot is inside the center console, but actually beneath the the front of the console (right). It is difficult to see, but it can be felt as raised tray just the right size for the remote control. Slip the remote onto the tray with the buttons up and press the Start / Stop button while stepping on the brake as normal.
The 2017 Escape has a new back up location (see below for earlier Escape models), which is changed again in 2018.
In the 2018 Escape, the back up slot is found in the front cup holder. The bottom is marked with radiating lines meant to indicate radio waves. Remove anything that may be in the cup holder and set the fob inside, as shown in the image at right. Once it is placed, use the Start /Stop ignition button to start the vehicle while stepping on the brake as normal.
And in 2019, the back up slot for the Escape is back at the front of the center console, beneath a mat that must be removed (right). The new Bronco, introduced in 2021, shares this location. A fob-shaped depression will be seen once the mat is removed. Place the fob on the spot with the buttons up. Once it is placed, use the Start /Stop ignition button to start the vehicle while stepping on the brake as normal.
The EcoSport, introduced in 2018, also uses a location in the front of the center console. Drop the fob into the slot with the key ring up and the buttons facing the back. After inserting the key fob, use the Start / Stop ignition button and brake pedal to start your vehicle as usual. And again, the key fob can be removed from the backup slot once the vehicle is started, if you wish.
New in the 2015 Mustang, the 2017 Fusion, and the 2018 Expedition (as noted previously), the backup slot is hidden under one of the cup holders.
The new all electric Mustang Mach E has a back up slot at the front of the center console storage area, next to the 12-volt power outlet (right). Place the remote control in the slot as shown (2) with the buttons facing up (or out).Once the remote control is in position, press the Start / Stop button while stepping on the brake to activate the high voltage battery.
Push Button Start is new to the Ford Pick-up line in 2015, first with the F-150, and it has two back-up start options. If the shifter is on the steering column, look inside the center console to the rear for the slot. Note that there are two console storage areas. The one needed and shown is beneath the center bench seat.
If the shifter is on the center console, the slot will be under the rubber mat in front of the shifter. Remove the mat and insert the Intelligent Access key with the buttons facing up.
In 2017, trucks with the shifter on the center console have the back up slot moved to one of the cup holders. Through 2020, the front cup holder is used, but it is moved to the rear cup holder starting in 2021. Remove the mat at the bottom (see image) by pulling the tab and stand the key fob up in the slot, buttons forward. Then press the Start / Stop button while stepping on the brake as normal.
In the F-250 or larger truck, the slot is located beneath the tray to the left of the cup holders in the center console. Remove the tray and the cover from the center console. The slot, which is in the shape of the key fob, or Intelligent Access key, will be exposed.
The compact Focus has five variations alone, with the Escape and C-Max sharing two of them and the Fiesta sharing one. The fifth Focus variation belongs to 2016 models only. All are located on the right side of the steering column near the windshield wiper lever. And see below for Fiesta and Focus models built after 2020 and not sold in North America.
If you see the transmitter symbol, which may have a key or tower in between the radiating lines, and you have a three button Intelligent Access key, slip the key into a small slot beneath the symbol, as shown.
If you have a five button Intelligent Access key, place the key against the transmitter symbol, as shown in the image, and start the vehicle. The vehicle will recognize the key, even if the key’s battery is dead. Use the Start / Stop ignition button and brake pedal to start your vehicle as usual.
If you see a cover, like the one shown above, there are two options. If a small slot or notch is visible, as seen in the image, pry off the cover using the mechanical key and insert the Intelligent Access key, as shown.
If the covering does not have a slot or notch to pry off the cover, which will include Fiesta models, simply hold the Intelligent Access key against the cover, similar to the five-button process shown above and as shown here, and start your vehicle using the Start / Stop ignition button and brake pedal as usual. The vehicle will recognize the key, even if the key’s battery is dead.
In 2016 and going forward, Ford made a change in the Focus. The back-up slot will be found at the bottom of the center console. It will appear as a depression in the floor of the console in roughly the shape of the key fob.
console storage compartment with the buttons facing up.
Fiesta and Focus models built after 2020 feature a small storage area in front of the shift lever on the center console. The area’s rubber mat must be removed, much like the pick up trucks with center console shifters seen earlier. There is even the mark of a key with lines radiating from it to point out the location (top arrow). Place the fob as shown (lower arrow) with the buttons up. Step on the brake and start the car using the Start / Stop ignition button as normal.
Finally, if you happen to have the GT model, the back up location is a storage tray at the front of the center console beneath its rubber mat, like the Fiesta and Focus above. Lift the mat and place the key fob with the buttons up, as shown in the image. Step on the brake and start the car using the Start / Stop ignition button as normal.
The latest models from all three manufacturers — with two exceptions — have a much simplified process. Staring with vehicle updates in the 2013 model year, simply press the Start / Stop ignition button with the Smart Key while depressing the brake to start the vehicle. We originally named this the back up start Method 6. If this does not work in your model, continue on below for a method that will.
The exceptions noted are first, an EV button (far left) in Kia EVs. It is pushed just like the Start / Stop button. The second exception is the 2021 Genesis G80, which is now a Seventh Method. This method has moved to the 2022 GV60 EV as well, and may yet be placed in other models. If the vehicle does not recognize the key fob or Smart Key, slip the Smart Key into the space behind the shifter dial and cup holders and in front of the leather of the console. See the second image to the left. Then, step on the brake and push the Start / Stop ignition button to start the vehicle as normal.
We must also add an Eighth Method, which is digital. In the new GV60, G70, GV70, G80 and G90, a registered smart phone or a pre-registered card key can be placed on the vehicle’s wireless charging pad. It is found in front of the center console storage area (left). Once in place, the vehicle can be started as normal.
The Kia Forte, Sportage, and Sorento and Hyundai Sonata (prior to 2014) use Method 1. Insert the Smart Key in the Smart Key holder, which is a slot inside the center console, then press the Start / Stop ignition button while depressing the brake. To remove the Key, press it, then pull. Check out the video below.
The Kia Magentis also uses a slot in the center console in Method 2. Insert the Key and then press the Start / Stop ignition button while depressing the brake. To remove, press the Smart Key inward past the detent and then pull it outward.
The Hyundai Genesis, built before 2014, uses Method 3, which is a slot located behind a door above the shifter. Insert the Key and then press the Start / Stop ignition button while depressing the brake. To remove the Key, press it and then pull it out.
The Kia Optima (prior to 2014) and Soul and Hyundai Equus use Method 4, which is a slot in the glove box. The slot is a little higher in the Equus. Insert the Key and then press the Start / Stop ignition button while depressing the brake. To remove the Key, press it and then pull it out.
The Kia Borrego uses the Method 5 slot, which is in the dash just below the Start /Stop ignition button. It should be readily visible. Insert the Smart Key and then press the Start / Stop button while depressing the brake. To remove the Key, release it by pressing and then pull it out.
To retrieve the mechanical key from either key fob style, slide the release lever located on the reverse side of the FAST key fob, as shown, and pull out the mechanical key. It can then be inserted into the lock cylinder at the back of the driver’s door handle and turned to unlock the car. So far so good…
As we noted, beginning with the 2016 Volvo XC-90 redesign as well as all Polestar models, a new style key fob is used (right). To retrieve the mechanical key or key blade, look for a slide lever on the top of the key ring end of the fob. This will free the front cover, which needs to be removed.
To do this, push the cover slightly down and away from the key ring end. It can then be pulled up and out, exposing the mechanical key. The key blade can then be lifted out.
With the previous generation key fobs, the is pulled away from the fob rather easily. Slide the spring loaded catch on the back of Remote Key (remote control or ‘clicker’) to the side. Pull the key blade straight out of the remote key. On some models, the lock cylinder (keyhole) at the back of the door handle will be visible. If so, use the key blade to unlock the door. See below if the key hole is hidden.
With the first generation Remote Key, a similar spring loaded catch will be found on the top of the fob, on the key ring end. As with the fob above, slide the catch to the side and pull the mechanical key away. Again, the lock cylinder (keyhole) at the back of the door handle may or may not be visible. See below if the key hole is hidden.
In the Volvo XC-90 and other redesigns going forward since 2016, as well as the Polestar 2, the key hole is also hidden, but easily found and nothing needs to be removed. Simply pull the door handle out as far as possible and the key hole is exposed, as shown in the image.
The Polestar 1 features a door handle that is flush to the car’s body. Push the front of the handle inward and pull away the back, as seen to the right. The key hole is now exposed. As above, insert the mechanical key and turn it clockwise to unlock. Remove the key blade and release the handle. Pull the handle once again and you are in the car.
A mechanical key is not available to unlock the Polestar 3 or Polestar 4. The smart phone app or the vehicle’s key card will be needed. With the Polestar 3, the card is touched to the front of the driver’s door handle (right). With the Polestar 4, the card is touched to the middle of the door pillar just behind the driver’s door (far right).
Press the key blade about a half inch straight up in the hole on the underside of the keyhole cover (right), found at the back of the driver’s door handle. This action will force off the cover. If you are in the dark, you may need to feel for the hole. Yes, you must remove a piece of the car, but it is ok and necessary. Use the mechanical key in the now-exposed lock to unlock the driver’s door.
Four key fob (remote control or ‘clicker’) versions may be seen in Toyota, Lexus and Scion models. The earliest version (left), used only in the Lexus LS for a few years, the mechanical key remains attached to the key fob. Pull the latch found on top of the fob. At the same time, slide the lever on the side upward until the key blade is fully exposed.
The mechanical key is removed from the remaining fob styles. Slide the catch on the top of most Lexus key fobs, or on the side of Toyota and Scion models. Some later 
Lexus models use this key as well. Pull the key ring from the fob while the catch is slid to one side to remove the emergency or mechanical key blade.
A slight variation in even later Lexus models has the slide lever on the top of the key ring end, but not on the mechanical key itself. Slide the lever and pull the key ring away to retrieve the mechanical key.
If the keyhole is not visible, insert the mechanical key into the slot at the base of the door lock cover located near the back of the driver’s door handle and lift slightly to pry away the lock cover and expose the lock cylinder. If you are in the dark, you may need to feel for the slot. Yes, you must pry off a piece of the car. Insert the key blade into the now-exposed lock cylinder to operate. The key can only be inserted in one direction, so turn the key over and try again if it does not go in the first time.
If you do not see a seam or a keyhole, you have the latest Lexus models, the NX, UX and RC as well as RX models built after 2016. This door handle style has since been incorporated into ES and LS models. Pull the driver’s door handle out as shown in the image to expose the keyhole. Insert the mechanical key and turn and you’re in. There is only a small amount of space, so actually turning the key can be a chore.
If you are fortunate enough to own the Lexus LC models, the door handles are flush to the body. Press the front of the driver’s door handle inwards, then pull the rear of the handle out. The key hole is then exposed behind the rear portion of the handle. As above, insert the key and turn and you’re in.
Finally, with the re-introduced Toyota Supra in 2020 come open and start features clearly taken from BMW! The key hole is hiding behind an oval shaped cover at the back of the driver’s door handle. Pull the door handle out and feel for a metal clip is behind the cap and give it a push outward.
The cap will practically fly off revealing the key cylinder. You are still removing a piece of your car and its still ok! Let go of the handle and use the mechanical key to unlock the door using the key cylinder that is now visible through the handle and you’ll be inside.
New in 2023, Lexus NX, RX, RZ and TX feature a rectangular pry off cover (right) at the back of the driver’s door handle. Slip a credit card or some equivalent into a gap at the front of the cover and pry the cover outward. When the cover clears the handle, push it from the rear to remove it fully. The key hole will then be exposed.
