Infiniti back up start page
Infiniti back up start pageA 2025 review of our Infiniti back up start page sees no changes whatsoever. In fact, what we learned is that the company has abandoned all back up start options that are not “push the button with the back of the key fob.”
All keyless or push button start vehicles offer a back up start option in the event that 
the battery in the key fob dies. Which they do all tooo quickly and at what is likely the worst possible time.
For years, Infiniti offered two options: push the start/stop button with the back of the fob; or slip the fob into a slot on the left side of the dash (right). This last option has been abandoned.
Then in 2018, the QX30 was introduced using a pull-out button akin to a version developed by the old Chrysler Corporation. The button can be removed and the key fob inserted into the space and used as a key.
The car was introduced in 2017 and both the method and the model were abandoned in 2019.

Volvo EV back up start
mark found inside the center console on the bottom and to the front (right).
Tonale back up start
Push button or keyless start cars and trucks need a location to touch or drop the key fob in the event the battery in the fob becomes depleted. This can happen as quickly as eight months, depending on use.
Since the introduction of the Giulia and Stelvio models, the only thing a driver of a keyless start Alfa Romeo had to do if their key fob died was to drop the fob in the bottom of the center console (right), a spot clearly marked by the outline of the fob itself. Time will tell if the new method in the Tonale will spread to additional models, old or new.
Polestar back up entry and start update
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).
Both models use a card reader at the front of the center console to start the car when the key fob’s battery has died. The reader doubles as a phone charger as well as a key fob charger for the Polestar 3!
Mercedes Back-up Start Page Update
As is true with most Mercedes-Benz models, the back-up spot is marked with the image of a key with lines radiating from it (left).
To activate the push button ignition in your Karma, place the key fob against the side panel near the driver’s left foot with the buttons facing the pedals. The panel is marked (right). The vehicle will recognize the key and display a message on the instrument panel. Hold the key fob against the panel until you have depressed the brake pedal and the Start / Stop button. This is an awkward move but it puts the vehicle in drive mode.
Starting the Ocean is a little easier, as the back up position is easier to reach. Look for what looks like an interlocked FJ on the panel to the left of the steering wheel (right). You might be able to feel the location as well. Place the back of the fob against the mark. The instrument panel will announce that the fob has been recognized, but you will need to continue to hold the fob against the mark while starting the vehicle.
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.
Mazda back up start review finds no changes
A full review of 2025 models results in no changes to the Mazda back up start page. All Mazda models use the tried and true “push the start/stop button with the back of the key fob to start the vehicles. In fact all the company’s models have used this simple and sane method since 2016.
As the battery in the key fob weakens, and it will at some point, the vehicle produces
a notice on the instrument panel pointing this out. However, everyone’s busy lives often result in putting replacing the battery in the fob until “tomorrow” or, because we are inundated with information from everywhere, the notice may simply be missed.
This is where a back-up start method is necessary. And welcome!
