Ive used door poppers in the past before and they have all been sh!!t so i bought a remote garage door opening kit off ebay (a 1 that allows for 2 garage doors)...
These are very good quality and the remote phobs feel solid and well put together.
This phob has 2 buttons (A for drivers side door & B for pass door)
I then bought 2 ford transit van central locking solenoids (very heavy duty! - infact they pull 3 amp unlike the cheap 1s from china that pull about 0.5amp)
I added a relay into the circuite that was man enough and bobs your uncle.
Ive sent them to colourtech to fit but if your thinking of doing the same il email you a wiring diagram i made.
I never added any fuses into the equation incase they pop and i cant get into the car!
However I will be adding a charge point some where incase my battery dies!
