Hi all. Hoping someone may have some advice. Just bought a Civic, has a Steel Mate alarm fitted. With the fob and with the key in either door, central locking will Lock car fine. On fob unlock will disable alarm, but doesnt work CL, in either door will unlock that door only.

Anyone come across this fault? Cant see it being a fuse or anything as the system works fine to lock.

Or maybe someone has a wiring diagram?

Many thanks in advance.
