There are three ways to open a BMW trunk if the battery has been disconnected. Let’s take a look at each one.

The easiest and most straightforward way to open your BMW trunk with the battery disconnected is by using your key. In older models, manual key access to the trunk is supported. To do this, you’ll need to:

- Unlock the back seat and fold it forward.
- Fold the rear seat panel simply by pushing.
- Find and locate a cable connected to the trunk lid lock and pull it.
- Lift and open the trunk lid.
#3- Use an External Power Source
If none of the above options are available, you may need to use an external power source. To do this, you’ll need to:
- Connect the external power source to the BMW’s battery.
- Turn on the power source to restore the car’s power.
- Once the power is restored, open the car’s door with the remote.
- Once the door is open, open the trunk with the trunk button or latch at the bottom of the inside of the door.
