Notes on programming the remote control: 

The presented remote control works in the Keeloq dynamically variable coding system. In order for it to work with the drive and open the gate, it must be programmed. In virtually every case, programming such a remote control requires access to the radio receiver located in the closed housing of the control panel or nearby. If you intend to operate a housing estate gate drive using a remote control purchased from us, you must have access to a radio receiver, which can additionally be secured with an access code. Without knowing the code, it is not possible to program the remote control, so we advise you to contact the estate administration to purchase a remote control that works with the estate gate drive.
