I have an early (1994) VR Calais, and have just replaced the ECU (engine computer), body control module (BCM) and Theft Deterrent Module (TDM) with the matching keyhead. But the old key that came with all this only worked twice before it died, so i need to replace the keyhead (I'm lucky it worked at all I think!). It is the later VS-type which are sealed at the factory so I can't just unscrew it and replace the battery myself. Anyway, I've had one of these bastards apart before and the battery is spot-welded onto the terminals, so it's a waste of time trying - Holden don't like people just replacing the battery at minimal cost, rather they want your money! :b: :b:
If I leave the new (unprogrammed) keyhead in the ignition for about 30-45 minutes, the security light goes off and I can start the car. However once I take the key out and the security light comes back on (after 30 secs) I have to wait another 30-45 minutes before it'll start the car again. Therefore it would appear that the 30-45 minutes is just an override period (i.e. the keyhead is not being prgrammed at all, rather the immobilser is overriden after this time).
My question is, so only a Holden (or Toyota) delaer with Tech-1 can permanently program keyheads, is this right? I don't want to have to pay them a cent unless I have to.
TIA
