Can the BMW Display Key Still Open the Car Door When It Runs Out of Battery?

[LaKeira]

Don't worry if your car's electronic key runs out of battery, as there is still a manual key inside the electronic key that can be used to manually unlock the door. Here are the detailed steps: 1. Operation: First, remove the mechanical key from the smart key and use it to open the car door. Then, press the key against the marked side of the ignition to start the vehicle. Finally, remember to replace the battery in the smart key. 2. Replacing the Battery: Remove the mechanical key from the smart key (the L-shaped key). Carefully observe the top of the smart key, which has deep and shallow grooves. Insert the L-shaped key into the shallow groove of the smart key and push it all the way in. You will notice that the back cover of the smart key automatically pops off. Remove the old battery, replace it with a new one, reattach the back cover, and reinsert the mechanical key.
