a friend of mine has recently had an M20 alarm system installed, but the engineer didnt ask him about setting any of the options when setting it up, and refused to give him the codes to do it himself when he rang up - he wants a call-out charge to come and tweak it, which is ridiculous!
specifically he is after the auto-arm (ie arms itself if you dont after 30secs), and did get a code from someone but it has now stopped his central locking arming after he starts the car, so would really appreciate all the codes if anyone has them anywhere?
cheers,
