How to Open BMW Trunk with Battery Disconnected?
If you need to open your BMW trunk with a dead battery, there are a few ways to do it. One way is to connect an external power source to the BMW’s battery and turn on the power source to restore the car’s power.
Once the power is restored, you can open the car’s door with the remote and then open the trunk with the trunk button or latch at the bottom of the inside of the door.
Another way is to release the hidden key in your key fob and locate the slot for your manual key.
On some BMWs, there will be a manual key slot on the trunk or under the lid. If so, unlock the trunk using the manual key.

What Are The Possible Solutions To The BMW Trunk That Won’t Open?
Here are some possible solutions:
- Open the trunk manually with the key blade: If the trunk release button is not working, you can use the key blade to open the trunk. To do this, remove the key blade from your key fob and insert it into the keyhole on the trunk lid. Turn the key clockwise to unlock the trunk.
- Open the trunk manually from inside: If your BMW doesn’t have a key slot on the trunk lid, you can try opening the trunk manually from inside the car. You need to go to the backseats of your car, release and pull down the center section of your seats and wiggle yourself through to the trunk. Once you’re there, just pull the emergency release handle and you’re good to go.
- Charge the car battery: If your car battery is dead, the trunk release button may not work. Try charging the battery and see if that helps.
- Check the valet switch: If your BMW has a valet switch, make sure it’s not turned on. The valet switch disables the trunk release button.
- Reconnect broken wiring loom: If the trunk release button is not working, it could be due to a broken wiring loom. Check the wiring loom and reconnect any broken wires.
- Replace worn off parts: If the trunk release button is not working, it could be due to worn off parts. Check the parts and replace them if necessary.
- Replace your BMW key fob battery: If your BMW key fob battery is dead, you may not be able to open the trunk. Replace the battery and see if that helps.
