Power locks refer to a feature in some vehicles that allows for remote or automatic locking and unlocking of doors. This means that instead of manually turning a key, pushing buttons on the door handle, or using a remote control device to activate the locks, power locks use an electric motor to perform these actions. Power locks can be programmed to automatically engage when the vehicle is in motion or locked, and some systems even allow for customizable settings such as delayed locking or automatic locking after driving for a certain period of time. Overall, power locks provide convenience and added security by allowing drivers to remotely control access to their vehicles without having to physically engage the door locks.
