Vauxhall and Opel use several back up start methods for its push button start models. In each case described below, once the key fob is in place, the vehicle can recognize that it is present.
The Ampera features a small hole in the storage compartment on the top of the dashboard. Flip open the mechanical key and push the key into the hole (right). Do NOT attempt to turn the mechanical key! Simply step on the brake, or clutch with a manual transmission, and press the Start / Stop button to start the car as normal.
Astra and Mokka models both use the front cup holder as a back up start location. Drop the key fob into the cup holder with the buttons facing up (right). Again, you can now simply step on the brake, or clutch with a manual transmission, and press the Start / Stop button the start to car as normal.
The Combo, Corsa, Crossland and Grandland models all share a common back up start process. Hold the electronic key with the buttons facing out on the marking on the steering column (right). Press the Start / Stop button with your other hand while stepping on the brake, or clutch with a manual transmission, and the vehicle will start as normal. Note that the key fob must be held against the mark until the car starts.
The Astra Van and Zafira models use a similar process, but the mark has a different appearance. The mark is round with a lock and lines radiating from it inside. And it is close to the Start / Stop button (right). Hold the electronic key with the buttons facing out on the mark. Press the Start / Stop button with your other hand while stepping on the brake, or clutch with a manual transmission, and the vehicle will start as normal. Note again that the key fob must be held against the mark until the car starts.
The Insignia model uses a unique back up location. There is a transmitter pocket behind the front cover of the center console in front of the shifter. Open it and place the electronic key on the spot with the buttons up (right). You can now simply step on the brake, or clutch with a manual transmission, and press the Start / Stop button to start the car as normal.
Finally, the Vivaro uses a slot above the Start / Stop button as a back up (right). The key fob must be slid into the the slot. Once it is there, you can step on the brake, or clutch with a manual transmission, and press the Start / Stop button to start the car as normal.

Holden uses three key fob or transmitter styles. To get in the vehicle when the key fob battery is dead, a mechanical key will have to retrieved from the fob and used to unlock the car.
The next two (shown to the right) feature a removable mechanical key and are quite similar (one has more buttons than the other). Each has a button on the side of the transmitter (remote control or ‘clicker’) near the key ring end. Press the button, as shown, and pull the key out.
The Commodore, Acadia and and Equinox models are hiding their key holes behind a cover at the back of the driver’s door handle. To remove the cap on the Acadia and Equinox, pull the door handle out to the open position. Insert the key into the slot on the bottom of the cap (number 3, right).
The cap on the Commodore is slightly different but there is still a slot under the cap. Insert the mechanical key into the slot and again hold upward pressure. Then rotate the key upward until the cap comes away.
In the Commodore, open the cover of the center console storage area in front of the shift lever. Place the transmitter in the transmitter pocket beside the power outlet, with the buttons facing up as shown in the image. Remove any additional items that might be in the area. Press the brake pedal and the engine Start / Stop button and you’ll be on your way.
The Equinox uses the left side cup holder as a back up location. Make sure there is nothing, particularly coins, in the cup holder, and simply drop the fob into it with the buttons facing up. The car will recognize the fob and pressing the brake pedal and Start / Stop ignition button will have you on your way.
The Trax, also uses a cup holder as its back up spot. However, there are three cup holders in the center console area, and the choice is the front and is separated from the two behind it. Be sure to use the one in the very front (see the image to right). Drop the key fob into the front cup holder, buttons up, and start the car as normal, using the Start / Stop button while stepping on the brake pedal.
The Spark uses a unique back up start location. The electronic key fob is placed in the center console transmitter pocket, which is in front of the cup holder and alongside the brake handle (image to the left). While in Park, press the brake pedal and press the engine Start/Stop button and you will be on your way.
Finally, the Acadia uses a back up pocket located in the back of the center console (image to the right). Drop transmitter or key fob into the pocket with the key ring up and the buttons facing the front. With the vehicle in Park or Neutral, press the brake pedal and the Start / Stop ignition button as normal. Once again, you will be underway.
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.
To start a Mercedes-Benz that uses the tapered SmartKey style, the engine Start / Stop ignition button must be removed. It appears to ‘float’ above the dashboard and is easily pulled away from the ignition lock. Insert the tapered end of the KEYLESS-GO key in the ignition lock and turn it to start and operate old school style.
Beginning in 2017, the ignition lock in AMG roadsters and coupes is found at the back of the center console storage area, as shown in the image. Insert the tapered key fob into the ignition lock and turn it to start and operate old school style.
Models using the new, rounded SmartKey fob styles , shown to the left, require that the fob be placed in a back up location or slot. These models, as of the 2019 model year, are the AMG, C-Class, E-Class and S-Class.
The new SmartKey fob style had spread through nearly the entire product line by the 2019 model year. However, the mark (the image of a metal key with lines radiating from it) is found in or near cup holders, which are at the front of the center console. See the two images at left. The 2021 S-Class Maybach uses the rear cup holder as well (second image) as well as a newer key fob. It is similar to the one shown above.
Also in 2019, Mercedes-Benz introduced the first of its electric and electrified models, the GLC 350e. And while the mark is also found in the cup holder, it too uses the image of the SmartKey (see the image to the right), like the updated C-Class models noted above. This will likely take over all model lines with time.
Finally come a small number of exceptions. Since 2019, the GLE and GLS SUVS use a slot, with the mark of a key with lines radiating from it, is found inside the center console storage area in the front. G-Class SUVs joined them in 2024. See the image to the left. Drop the key fob into the slot and start the vehicle as normal.
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.
There are several methods for starting a Honda or Acura vehicle. To start a Honda and the newest Acura models lacking a slot, touch the “H” in the Honda logo or the “A” in the Acura logo on the remote control to the Start / Stop button until the small indicator light in the button begins to flash. For the next 30 seconds, the vehicle can be started using the Start / Stop button normally. You can also simply press the Start / Stop button with the remote control itself, while stepping on the brake of course.
exactly the same.
In earlier Acura models (newest models are above), there is a slot for the remote control (key fob) to the left and below the Start / Stop button. Insert the remote and use the Start / Stop button to start the vehicle as normal.
In the oldest keyless start Acura models, there is a cover on the ignition switch that must be removed. This will allow the use of the mechanical key built into the key fob. To remove the ignition switch cover, slip the built-in key into the parallel slot underneath the cover. Push the key in while pull it towards you at the same time and the cover will come off. Once the cover is removed, the mechanical key can be inserted and turned to start the vehicle.
Some BMW and Mini models already require that the key fob be inserted into the dashboard next to the Start/Stop button. If the key fob battery is dead, the vehicle will recognize the fob when inserted. In “Comfort Access” models, the slot is only needed if the fob’s battery dies, or if electrical interference interrupts the fob’s signal. Insert the fob into the slot and use the Start/Stop button as normal.
For other BMW or Mini models, hold the remote control against the marked area on the steering column and press the Start/Stop button within 10 seconds while depressing the brake.
The smart phone recharge pads also act as new start points. A properly connected key card or a smart phone holding the proper BMW app touched to the pads will allow the car to start. The pad is found in front of the cup holders in the i4 (first image) and on the lower level of the iX console (second image).
The car features a wireless cell phone charging station inside the center console. There is also a bulge into which the Display Key can be slipped, with the lock button up and out. The Key is charged with a micro USB cable, a micro USB port on the Key (see the arrow on the Display Key) and the USB port at the back of the console.
The CX5 was the first model to use Method 3 and by 2016 all Mazda models use this method. Push the brake pedal, or the clutch pedal if you have a manual transmission. This will cause the indicator light in the Start / Stop button to flash green. While it flashes, touch the back side of the key fob to the Start / Stop button, which will cause the green indicator light to stop flashing and remain lit. Push the Start / Stop button to start the engine as normal – or with the fob itself.
Method 2 is found in the CX7, CX9, MX-5 and RX8 models. Remove the Start knob cover by pushing both release buttons and pulling the cover off exposing the key cylinder. Slide the auxiliary key out from the bottom of the advanced key (see above) and insert it into the cylinder. Turn the key to start the engine.
For Method 1, found in the Mazda3 (including MazdaSpeed3) and Mazda6 prior to 2014, slide the auxiliary key out from the bottom of the advanced key (see above). Use the auxiliary key to remove the key slot cover located on the right side of the steering column. Depress the clutch (manual) or brake pedal (automatic) until the ring around the key slot starts flashing. Insert the auxiliary key into the slot while it is flashing, but do not turn the auxiliary key in the slot. Press the push button start to start the engine.
