The remote control operates the central locking system and also the anti-theft alarm if one is installed.

The remote control has three buttons:

1. Locking
2. Unlock
3. Functions for operating the tailgate lock unit:
   • Unlock tailgate (3D and 5D)
   • Open tailgate (convertible)

When a button is pressed, the remote control sends a signal that is received by a receiver. The receiver processes the signal and transfers it to the TWICE control module.

The signals from the remote control contain an identification code that is unique to each remote control. It is a so-called "rolling code" that is changed each time the button is pressed. If the code is valid, the control module will execute the command.

When locking and unlocking, the remote control sends codes continuously for as long as the button is pressed. If the receiver misses the beginning or the entire signal from the remote control, the locking or unlocking button must be pressed again.

The transmitting range of the remote control is normally approximately 5 - 10 meters.
