Types of modul central locking system

A car's central locking system locks and unlocks all doors from a single control point. It enhances convenience and security for vehicle users. Most modern cars have this central locking system. The modul central locking system has various types, which include:

• Basic central locking system

  A basic central locking system is the most common type found on many vehicles. The basic system locks and unlocks all doors simultaneously using a switch or a button. The button or switch is located on the driver's door. Users can activate the locking system when the vehicle is in motion or before entering the vehicle. This system enhances security by allowing users to lock the doors from inside the car.

• Remote keyless entry

  Remote keyless entry is a popular central locking system among many car owners. The remote keyless entry allows users to lock and unlock the doors from outside the vehicle using a remote control. Users can lock and unlock the doors with a push of a button. They can also activate the panic alarm from the remote when facing an emergency. The remote keyless entry enhances convenience, especially when the car owner is carrying luggage or groceries.

• Smart entry system

  The smart entry system is an advanced central locking system found in most luxury vehicles. For example, the smart entry system automatically locks and unlocks the doors when the key fob is detected nearby. Users don't have to touch the key fob. The system also allows doors to open with a door handle touch when the key fob is in close range. The smart entry system is convenient for users since it eliminates door locking and unlocking tasks.

• Active security central locking

  The active security central locking system is ideal for high-security vehicles. The system locks the doors and windows automatically when the vehicle is in motion. It also activates security measures, such as immobilizing the engine to prevent unauthorized access. The active security central locking system provides extra security for valuable goods in transport.

• Two-stage unlock

  The two-stage unlock system is a central locking feature found in modern vehicles. It improves convenience and enhances security. The two-stage unlock system allows users to unlock all doors or the driver's door alone. The system activates the first unlock stage with a single remote button press. A double press activates the second unlock stage. The two-stage unlock system is useful in busy environments where security is a priority.
