To start your Alfa Romeo Giulia,Stelvio or Tonale with a dead key fob battery, you will need a back up location to place the fob. For the first two models, it can be found in the center console.
Clear away anything cluttering the bottom of the console. You should then see the outline of the key fob on the floor (right) with lines radiating from the top. These are meant to indicate radio waves.
In the Tonale, the spot is in the front cup holder, as shown to the right. There is no marking we are aware of.
Place the fob on the spot. The car will recognize the fob even though the fob’s internal battery is dead and will start normally. The key fob can be removed once the car is started.
Note that Alfa Romeo says that to shut down the engine when the fob’s battery is dead, you will need to press and hold the Start / Stop button for several seconds. We’ve not seen this in any other vehicle…

Alfa Romeo introduced push button start in the new Giulia model in 2017, followed by the Stelvio in 2018. They use the same key fob.
Getting Inside
A mechanical key will be needed to unlock the driver’s door. The fob will need to be removed from any key ring its attached to first. The mechanical is hiding in the fob and the cover on the back must be removed to find it. Squeeze the sides of fob at the wide end marked by raised ribs, as shown in the image (right).
The back cover can now be pulled away moving, it towards where the key ring was attached. The mechanical key is seen inside and can then be pulled out.
Insert the key into the lock cylinder at the back of the driver’s door and turn, and you’ll be in the car.

Starting a Mitsubishi will depend on whether or not there is an actual Start / Stop button. If there is, continue below.
Push Button Start
Most newer Mitsubishi models use a Start / Stop button. With most of the newest models, built roughly 2018 and later, simply press the the Start / Stop ignition button with the back of the key fob, as shown to the right, while stepping on the brake. The key fob or FAST key will be recognized and the car will start.
The newest Outlander models use the method shown above. However, in earlier models, there will be a slot to accept the FAST key fob. It may be inside the glove box (right) or somewhere near the front of the console (below). Early Outlander and all older and current RVR models have a slot in the glove box. Later Outlander models use a slot near the console. See examples below.
In other models, the back up slots will be found somewhere on the dashboard, generally in the vicinity of and in front of the shifter. We did find one model, sold outside North America, the Shogun, where the slot is actually alongside the console, as seen to the right.
Mirage models also continue to use a slot found at the very front of the center console in front of the cup holders (right). Wherever the slot is, it will look like a small rectangular opening just the right size for the key fob. You may be using it for business cards or coins! Remove them!
Once found, insert the FAST key fob into the slot. The engine can then be started normally, stepping on the brake while pressing the Start / Stop ignition button. Mitsubishi recommends removing the key fob once the vehicle is started.
Keyless Turn Knob Start
If there is a keyless turn knob, on the steering column, it is a three step process however. Start by slipping the back end of the mechanical or emergency key into the FAST key fob. It will then look like the illustration and the feel of a more traditional ignition key (right).
This assembled key will be needed to turn the ignition switch, which is hiding under the turn knob on the steering column. When the key elements are assembled, the transponder is close enough to the switch’s antenna module to be recognized. The module supplies the power when the key’s battery is discharged.
Remove the ignition knob cover (above right) by pushing the lock release buttons on the each side. Then insert the emergency key into the now exposed lock cylinder (right). The vehicle can now be started in a traditional key-start manner by pushing, then turning the key. See the illustrations.
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.
Remember that only proper service and repair procedures will ensure the safe and reliable operation of your car. In addition, proper safety procedures and precautions, such as the use of safety goggles, the right tools and the equipment should be followed at all times to eliminate the possibility of personal injury or improper service which could damage the vehicle or compromise its safety.

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.
In 2019, the AMG gets the new SmartKey, described next.
AMG Back-up Slot
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.
Warning! Do NOT attempt to remove the Start / Stop ignition button!
C-Class Back-up Slot
E-Class Back-up Slot
The back up slot in each model is found at the very front of the center console. Each slot is slightly different depending on the model, and an image from each model is shown here.
Each slot is marked by the image of a metal key with lines radiating from it, except for the C-Class, which has an image of the SmartKey fob itself (left).
S-Class Back-up Slot
Make sure that the slot is empty. Remove the SmartKey fob from the key ring and slide or place the fob into the slot with its buttons facing up. You can now start the car as normal. The car will recognize the key fob even if the fob’s internal battery is dead.
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: For reasons unknown, all the Mercedes models we’ve tested have s light delay built in after the start/stop button is pushed and the key fob being recognized. Not to worry…
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.

Early Audi models use a slot in the dashboard but do not use a Start/Stop button. The fob itself is pushed to start or stop the car. If the key fob battery is dead, the vehicle will already recognize the fob when inserted.
Audi and Volkswagen models that use the Start/Stop button and have a slot in the dashboard, as shown, insert the fob into the dashboard slot and press it to start while depressing the brake pedal as if the fob were the Start/Stop button. The actual Start/Stop ignition button is disabled.
In models that do not feature a slot for the fob, look for the symbol of a key with lines radiating from it, as shown. It will be to the right of the steering column on the dashboard (Audi) or on the right side of the steering column itself (VW).
In the latest Audi Q7, the symbol is just in front of the center console storage area. Touch the tip or the back of the fob to the symbol – or in the case of Q7 simply drop the fob on the symbol – and press the Start/Stop button while depressing the brake pedal, all at the same time.
In 2018, the mark is moved to the driver’s side cup holder in the Audi A5 and Q5. This is also true of the A3 and Q3 beginning about 2021. The all electric eTron GT uses this mark as well. The mark is smaller and shaded and so a bit difficult to see. As with the Q7, the key fob can be dropped into the cup holder, and starting the car becomes a one hand (and one foot) operation. Press the Start/Stop button while stepping on the brake. It took two tries to before the key fob was recognized in our test car, but it did work.
However, in 2019, the A5 now has the mark at the front of the center console storage area, as shown to the right. Again the key fob can be dropped onto the spot, and starting the car needs only a single hand (and foot). Press the Start/Stop button while stepping on the brake. Our test car started first time in this case.
The new (2019) Q8, and now the Q7, also has the marking in a cup holder. It is the front one in this case. However, we noted a slot between the cup holders adjacent to the 12 volt power outlet and shaped very much like the key fob, Sure enough, the fob was recognized when placed inside the slot.
Models are now being electrified. The e-tron GT uses the front cup as in the images above. However, the original e-tron and e-tron Sportback the mark is found in front of the of the cup holders (right). We have not had access to all electric models, but a back up location will likely be found in or near the cup holders.
By 2023, the A4 and S4 models sport the mark on the center console, just in front of the console storage area.
All this is to say that there will be a mark somewhere in all Audi and VW models, and in all likelihood if it is not found on the dashboard or the side of the steering column, it is most likely to be found somewhere on the console area.
The mark in Volkswagen’s new ID4 EV, the mark is moved to the front area of the center console. This follows the trend in Audi models. Originally, the front area is for storage and has removeable spacers. We found the mark by removing the front spacer (first image). Later, the same area was converted to cup holders. The mark is found in the first cup holder (closest to the driver) (second image).
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, veryhard 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.

Beginning with the 2020 XC-90 redesign and the newer key fob style, plus Polestar EV models, a sensor location is provided for the key fob. It is found in the second cup holder in the center or tunnel console. An illustration of a key with lines radiating from it can be seen at the bottom of the cup holder.
Note that you will find the mark inside the small center console of the Polestar 2 (right), which is also the location of the second cup holder! Place the key fob in the cup holder. The vehicle will recognize the fob even if the fob’s internal battery is dead. The alarm will be turned off and the car can be started as normal, by turning the Start / Stop switch to the Start position while depressing the brake. Note that the Polestar 2 is started, or powered up, by stepping on the brake.
In the Volvo XC-40, the company’s first all electric model, and subsequently the C40 and EX40 EVs, the mark will be found inside the center console on the bottom and to the front (right). It too features the mark of a key with lines radiating from it. Place the key fob on the mark. The vehicle will recognize the fob even if the fob’s internal battery is dead. The alarm will be turned off and the car can be started as normal.
Beginning in 2021, a smart phone app became available for both Volvo and Polestar models and can be used to open and start these vehicles. A key card is added beginning in 2024, and the key fob cannot be used to start the car with a depleted battery.
So, in both the Polestar 3 and 4, the key card is placed on the spot used to charge your smart phone (right), which is at the front of the center console. The key fob for the Polestar 3 can be recharged on this spot, the card reader, as well.
In any case, using the key card to start your car requires that noting else is on the card reader. It cannot simultaneously charge a phone and a key fob. The reader cannot read the card either if something is being charged.
In older, second generation keyless start Volvo models, an ignition slot comes into play. The slot will be found either alongside or below the Start/Stop ignition button. Insert the key fob into the ignition slot. This will turn off the alarm and allow the vehicle to be started as normal by pressing the Start / Stop button while depressing the brake.
The vehicle will recognize the key fob even if the fob’s internal battery is dead.
The remote key can be removed from the ignition slot by pressing the it in lightly. The remote key will then be ejected slightly and can be removed from the slot.
In first generation keyless start models, the ignition switch is turned in normal conditions, similar to key start vehicles. There is a dummy key that needs to be removed. Press the the button found on the side of the dummy key, which frees it to be pulled away. The key fob can then be inserted in its place and the vehicle can be started (right).

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.

The Porsche Entry & Drive System may or may not feature a dummy key that needs to be turned to start the vehicle. If your vehicle does not have this key, the car’s key fob, even if its internal battery is dead and won’t let you in, will start the car. It will be recognized once placed into the ignition switch.
If there is a dummy key, it will need to be removed in order to use the key fob in the ignition. The owner’s manual holds a somewhat complicated set of removal instructions that will leave you exposed and vulnerable for far too long. Ignore the instructions and do the following.
Make two attempts to start the car normally. The car’s instrument panel will then note that the dummy key can now be pulled away. Once this is done, the vehicle’s key fob can be inserted into the ignition switch and the car started normally. The fob will be recognized even if the fob’s internal battery is dead.
Click here for videos of both the open and start processes.
Porsche Hybrid
The Panamera Hybrid continues the use of a dummy key in the ignition. However, if the fob’s battery is dead, a new process is needed, which includes the use of a back up location for the fob.
Lay the key fob, buttons up, in the compartment in the front of the center console to the left of the cup holders. Turn the ignition dummy key to the start position (position 2) and back to off. Turn the dummy key back to the start position a second time and the vehicle will start. The instrument panel will also acknowledge that the key fob has been recognized.
