If you’re a BMW owner, you know the convenience of keyless entry and push-button start. But what happens when your key fob battery dies? Don’t worry, most BMWs are equipped with a mechanical key hidden inside the fob. This guide will walk you through how to access and use this key to unlock and start your BMW.
Locating and Using the Mechanical Key
First, you need to find the mechanical key. Look for a small release button on your key fob. Press it and slide out the hidden key. This key is your backup for situations like a dead battery.
Next, locate the keyhole on your driver’s side door. On newer models, it might be hidden under a small cover on the door handle. Gently pry this cover off to expose the keyhole.
Insert the mechanical key and turn it to unlock the door. Once inside, be sure to replace the keyhole cover to prevent loss or damage. Unlocking the door manually might trigger your car alarm. Don’t panic; the alarm will usually shut off once the car is started.
Starting Your BMW
Now, how you start your car depends on your BMW model.
Models with a Key Slot Ignition:
This is straightforward. Insert the mechanical key into the ignition cylinder and turn it just like you would with a traditional car key.
Models without a Key Slot Ignition (Push-Button Start):
Even with a dead key fob, you might still be able to start your car. Locate the key symbol on your steering column, usually near the start button. Hold the dead key fob against this area. Then, press the brake pedal and push the start button. The car should recognize the fob and start.
Important Considerations
If you’ve lost your key fob entirely and only have the mechanical key, you can unlock your car but might not be able to start it if your model has push-button start. In this case, you’ll need to contact a BMW dealership or a qualified locksmith for assistance. They can help you replace your key fob and get you back on the road. Keep in mind that replacing a lost key fob can be more expensive than simply replacing a battery.
When to Contact a BMW Dealership
- Lost Key Fob: If you have lost your key fob completely, you will need to visit a dealership for a replacement.
- Key Fob Malfunction: If your key fob is not working even with a new battery, there may be an internal malfunction requiring professional attention.
- Ignition Issues: If you are experiencing difficulties starting your car even with a working key fob and mechanical key, there might be a problem with the ignition system.
By understanding how to use your BMW’s mechanical key, you’re prepared for unexpected situations like a dead key fob battery. This knowledge can save you time, money, and frustration.
