BMW is a luxury German vehicle line manufactured and sold around the world. The car company features sedans, sports coupes and sport utility vehicles. A central locking system controls the door locks and trunk luck. The trunk may be opened by the push of a button from the inside or outside of the vehicle. A key remote that isn't properly working may prevent a BMW trunk from opening. How the key remote is used may also prevent a trunk from opening.
Open the trunk from the inside of the car. Press the "Trunk" button located to the left of the steering wheel.
Check your distance when using the key remote. The "Trunk" button on the key remote only works from a distance of 3 to 25 feet. Stand closer or farther away if your trunk button doesn't work.
Check for objects blocking the trunk. Ice and dirt can clog the opening of the trunk. Remove and/or clean objects from the trunk to open.
Change the battery in the remote. Take the integrated key out of the remote. Insert a flathead screwdriver under the battery cover to pop it off. Remove the old battery. Replace with a new battery. The battery model number can be found on the surface. Place the new battery in the remote and snap the cover back on.
Take your vehicle to an authorized BMW auto mechanic. The lock mechanism may be broken in your trunk. A trailed professional can properly diagnose and fix such a problem.
