If your BMW key fob battery dies, you might be stranded. Don’t panic! Most BMWs have a mechanical key hidden inside the fob. This guide will show you how to start your BMW with a mechanical key, even with a dead key fob.
Locating and Using the Mechanical Key
The first step is finding your mechanical key. Look for a small release button on your key fob. Press it and slide out the hidden metal key. Some BMW models have a keyhole cover on the driver’s side door handle. You might need to press a spring clip or use the key to pry it open. Once the cover is off, insert the mechanical key into the door lock and turn to unlock. Remember to replace the keyhole cover after unlocking. Opening the door with the mechanical key might trigger the car alarm. Don’t worry, it will shut off once the car starts.
Starting Your BMW: Two Scenarios
There are two ways to start your BMW with a mechanical key depending on your car model:
1. BMWs with a Key Slot Ignition:
If your BMW has a traditional ignition cylinder, simply insert the mechanical key and turn it to start the engine just like you would with any other car.
2. BMWs with Keyless Ignition (No Key Slot):
For BMWs with push-button start, you’ll still need the key fob, even if the battery is dead.
- Locate the Key Symbol: Look for a small key symbol on your steering column, usually near the start button.
- Position the Key Fob: Hold the dead key fob against the area with the key symbol.
- Press the Brake and Start: Press and hold the brake pedal, then press the engine start/stop button as you normally would. The car should start.
Important Considerations
- Lost Key Fob: If you’ve lost your key fob completely and your BMW has keyless ignition, you won’t be able to start the car. You’ll need to contact a BMW dealership or a qualified locksmith for assistance. They can program a new key fob for your vehicle.
- Key Fob Replacement: It’s a good idea to have a spare key fob programmed and ready in case your primary fob is lost, damaged, or the battery dies. This can save you time, money, and frustration in the long run.
Conclusion
Knowing how to start your BMW with a mechanical key can be a lifesaver in emergencies. While the process varies slightly depending on your car model, understanding these simple steps will ensure you’re not stranded by a dead key fob battery. Remember to consult your owner’s manual for specific instructions related to your BMW model.
