Some vehicles have a manual start feature, while others have a keyless start feature integrated into the key fob.

    There is still a way to start the car if your keyless entry system uses the START button and there isnt a mechanical key hole. Press the START button with the key fob. If the key fob battery is dead, certain manufacturers feature a backup system that enables this approach to function. For instance, many more recent Fords include a pocket in the dashboard or a slot on the steering wheel where you may place the actual key fob to start the car.

    There is no scenario that automakers havent already encountered as a result of their departure from the conventional key during the past few years. Visit the OEM website or call roadside assistance if you are locked out or cant get the car started. Theyll quickly get you back on the road.

    The above activation methods assume you have a new key fob ordered from an authorized BMW dealer or third-party reseller, such as BimmerTech, which was made specifically for your vehicle based on its VIN. These methods will not work with a used key fob, or one intended for use with another vehicle. The majority of key fobs available for sale through online marketplaces such as eBay fall into this category.

    To improve vehicle security, your BMW’s head unit will only allow activating fobs with one of a predefined list of identifying keys. This list of approved fobs is unique to each vehicle, preventing criminals from pairing other key fobs with your vehicle to gain illegitimate access to it. Reprogramming your vehicle or a used key fob to allow the two to be paired would require overriding key parts of your BMW’s anti-theft system, potentially compromising its security.

    Like BMW, we recommend only attempting to use key fobs ordered from a BMW dealership or a reputable third-party reseller, such as BimmerTech.
