HOW TO OPEN TRUNK 02 540I WITH DEAD BATTERY?

To open the trunk of a 2002 BMW 540i with a dead battery, you can use the manual key blade that is integrated into the key fob. Insert the key into the driver's door lock to unlock the car, then access the trunk release lever inside the vehicle. If the lever doesn't work due to the dead battery, you may need to fold down the rear seats to reach the trunk or access the trunk release directly from the inside. Alternatively, jump-starting the battery can also restore power to operate the trunk.
