Car Battery Dead? Here’s How to Unlock it

AvatarByCarl Frisch

When a car’s battery is dead, it may not be possible to unlock the vehicle. This is because the power from the battery is what unlocks the doors. Without a working battery, the car will not have enough power to open the doors. In this case, it is necessary to jump start the vehicle or replace the battery in order for it to be unlocked. Jump starting involves connecting another car’s battery to provide enough power to start the engine. If this works, then it should also provide enough power to unlock the doors. However, if jump starting is unsuccessful, then replacing the battery may be necessary in order for it to unlock properly.
