The VIPER 211HV central locking control is probably the world's best-selling central locking remote control and was developed and manufactured by market leader VIPER in the USA.

FEATURES
- Central locking control:
Control of the central locking system installed in the vehicle via radio remote control. The outputs are 30 amp onboard XCR relays for controlling virtually any factory-installed central locking system or aftermarket actuators. Data bus-controlled systems can also be remotely controlled via optional CAN bus modules.

With the radio remote control, other functions on the car, such as the electric trunk opener, can be remotely controlled from a distance of over 50 meters.
