It is very rare however some vehicles require a motor to be installed in the drivers door to allow an alarm system to lock and unlock the doors upon arming and disarming the alarm.
Some common vehicles are:
- Daihatsu Terrios
- Nissan Skyline
- Mazda Bongo
- Mazda Eunos
- Toyota Estima
We will do our best to advise if these are required before installation of your chosen alarm system however this can vary, especially on imported vehicles.
