so, the light on my key activates when I press the button, the light on the receiver unit in the car works when I press the test button....but the alarm has just stopped working. got in my car, drove home, got out and it wouldn't set the alarm or lock the doors!
There's only flipping air between the key and the receiver, and the battery can't go that dead in the space of an hour surely?
I'm doing up a document on this... You have the IR sender I expect? I have photos and a detailed repair method. Lock the car with the key for a shortwhile... I'll let you know when the document is ready.
