I don't know if there is one, but if there is, where is the module located that controls the operations of the keyless entry and alarm inputs and outputs? I have a 2002 Cavy.

On all 2000+ cars, the keyless entry and alarm functions are controlled by the Body Control Module (or BCM). It's under the driver's side of the dash, a black plastic box about 3"x6" in size. It's clipped into a white plastic holder. There's three connectors on the top edge of it, one's got light blue plastic, one's brown, and the last is purple. Should have a sticker on the front face with "RFA" on it if it's a keyless car... The cars w/o keyless won't say RFA... but I don't know what they do say
