Car locks are some of the very basic security installations in the world today. They act as a useful defense against unauthorized entry into your vehicle especially when left in a parking area. They also protect your young ones from falling off the vehicle when it is in motion. Car locks can either be activated manually or by use of a remote. There are various doors locks for each specific model out there.
The Following Are Some Essential Parts Of A Door Lock:
The Door Lock Switch
These are units operated by the simple touch of a button. They are commonly found in the door pull or armrest areas of most vehicles. Once you press the door lock switch, you complete a circuit that sends a signal to the body control module of the car. This in turn engages the door lock activators which move a rod to either engage or disengage the door handle from the latch cable. To facilitate ease of use, the door lock switch in most cars has images of a locked and unlocked padlock to specify the kind of function activated by each particular switch.
The Key Bob
Key fobs are some of the most advanced security tokens in modern automotive. The units come in with built-in authentication systems and help in creating a connected system from which a series of commands are executed. A key fob is specifically designed to offer a two-factor authentication capability. This type of authentication makes the use of a physical item as well as a second virtual input in order to grant or restrict access to the vehicle. For example, a card maybe used alongside a memorized complement, and in many cars this second step features the use of memorized codes.
When the latch of a car goes up, the handle on the outside part of the door connects to the mechanism used to grant access. This is the opening process. When the latch goes down, the same handle now detaches from the locking mechanism, and this action now traps the various other parts of the lock, preventing opening unless the original process is re-initiated.
Actuators And Assorted Parts Of Door Lock
This is the hidden mechanism that initiates the process of locking and unlocking a car. It comes alongside gears, an electric motor and a linkage device, with all the three parts moving together to either retract or depress the car locking system. Modern cars have a complicated setup which requires electric signals to operate. Once an anti-theft code is send through the various controls, a chain of events starts and ends only when the locking or unlocking action has been completed. When contacts and circuits wear out, actuators may actually fail, compromising the safety of the entire car locking system in the long-term. At other times, wear is cause by extended use.
Over the years, the parts of a door lock in cars have become consistently more advanced, which is a step in the right direction given the large number of safety concerns for both people and property in vehicles.
