Title: 1994 Omega dead remote
Post by: MonzaGSE on 19 May 2020, 09:15:39

The infrared remote on girlfriends Omega suddenly died yesterday. Car wouldnt start because of immobilizer. Had to go home to get spare key to get the car to start. The spare key have a bad microswitch but works. The key she has been using have been in good condition before it suddenly died. Changed batteries two times and even took it apart. 6v gets from the batteries to the circuit board inside the remote but nothing happens. The little red light dont light up and car dont react. All solderjoints look Ok to an amateur. Talked to Opel dealer who said these remotes are no longer available. They also said that remote needs to be new. A used remote from a different car cant be reprogrammed. Parts number on defective remote are 90459461 and 90460834. Both are stamped on it.
The question is do anybody know a place to get a new remote, and is it true that a good used one wont work? As i have previously understood the old infrared system requires Tech 1 to programme.

I have an ecu set from a 95/96 2.5 manual which I think has 2 remotes separate from the keys, would be cheap as it's have been on ebay for years with no interest  ;D

Im not sure how much is involved in changing the centrallocking/immobilizer system? What parts are needed to match? Car has central locking and immobilizer but no alarm. As i understand the engine ecu dont really have anything to do with it on the IR system. Dont know if the immobilizer is build into the central locking ecu or if its a standalone unit.

I may be wrong (I often am  ::)) but I think a wiring mod will take the immobiliser out of the equation.

Central locking should still be happy to work off the key in the drivers door.

I didn't post this yesterday because I thought you would still need a way to switch the alarm off. - shows how many years it is since my 94 Omega went to the crusher.............
