How to Replace the Battery in a BMW 7 Series Remote?

Press and hold this button with your left hand, then use your right hand to pull out the car's mechanical key. Continue pulling the mechanical key until it is completely removed. Locate the position marked with the word 'open' on the end face of the car key. Insert a flat-head screwdriver into the 'open' position and gently pry the car key up and down. Take the new battery and, aligning it along the edge, gently press it downward. If the battery surface fits snugly against the key surface, it indicates that the battery installation is complete.
