How to Start a BMW or Mini with a Dead Key Fob

This page holds all of the emergency start or back-up start procedures needed for BMW vehicles if the battery in the key fob dies or if there are electrical signals interfering with the fob.

Starting a BMW or Mini

Even if your vehicle is not responding to the key fob, that fob is all you need, and must have, to get your car started.

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 nose of the remote control against the marked area on the steering column and press the Start/Stop button within 10 seconds while depressing the brake. With the new 2025 Mini Cooper, place the back of the new style key fob against the mark.

The process remains the same in the new EV line from BMW, starting with the i4 and iX. However, there are now two additional back up start methods available in these vehicles.

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).

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.

Recharging the Display Key

In an automotive first, BMW‘s Display Key (right) actually has a rechargeable battery. The display is automatically disabled when the charge is low, which is a major hint that the device needs to be recharged!

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.
