door lock

On the interior of your car doors are lock buttons that you can operate by hand or with your key fob. This is the visible component that connects to the actuator that's inside the door. This locking actuator also connects to a lever that allows the door to be opened once you unlock the door.

The latch locks or unlocks the door when pulled. Some car door handles require an electric key, passcode or fingerprint, whereas some can be operated via traditional keys. Read this guide to know about the evolution of car keys.The locking mechanism itself is a push/pull lever or pin system on the inside of the door. In a strictly manual system, each door must be manually unlocked, with only the driver's door unlockable from the outside, while the rest must be unlocked from inside the car.

The strike plate is attached to the door frame with screws. The metal bolt of the deadbolt lock slides into the strike plate to secure the door soundly to the door frame. A high security strike plate is required to keep the metal bolt from being kicked from the door frame when locked.An electric door strike is used on door frames for access control. It activates every time someone tries to open the door. When a person uses an ID card, a fingerprint, or enters a pin code, the system sends a signal to the electric strike. The electric strike is then released to grant access if this signal is correct.
