Changing keys and central lock unit
« on: 06 August 2018, 17:32:09 »

I am about to replace my old Omega with another that is in better shape. The "new" one only came with one key and in that key the battery older is loose.

I was thinking that since the old one will be scraped for parts I could move all the lock parts over to the "new" one and then get the two working keys I got to be used in the new car.

Is that doable, if I move over all stuff it would work, right?


Thanks

My old one is a 2001 that the stuff is coming from. The one who's going to get it is a 2002.

Thanks

OK, so:
All mechanical locks and ignition barrel.
Immobiliser ECU
Alarm ECU
Engine ECU

Engine ECU as well?

That will be a problem since the old one is a 3.2L  and the "new" one is a 2.6L

If both auto, it won't matter  :y

Swapping everything is easier than trying to remember which key chip goes with which ecu when you have all the bits laid out.

By using EVERYTHING from one car, you know that it all works... The remotes, the keys, the alarm.

Last thing is to swap the car pass over, but write the chassis number and radio code (if relevant) onto the car pass for the car that you are fitting them to. That way, if you ever need anything programming then you have the information to hand

I might be Wong, why not just get a key cut,and cloned by the locksmith.  Or can't you do that with GM keys.

You need the transmitter for the central locks.

Well the old one will anyway be taken apart for spares so I might as well take care of those parts. But yes it would be easier to get a new key. I have yet checked what they charge for that at my local GM-supplier. I have to check that.

OK So I have now got the vital parts out, all the locks and the ignition switch transmitter and the ECU for the locks. But I have seen somewhere that there should be another box located behind/above the glove box area. I can only find the Automatic trans controller there.

Should there be anything else besides what I've got on this picture?

Both the old and new ones have the alarm.

That looks complete except...

1. Driver's door lock barrel.
2. Tailgate lock barrel.
3. Engine ECU.
4. Car pass.

The Delphi unit is the alarm/remote central locking unit

I wrote "all locks"  ;)

You earlier said that I didn't need the Engine ECU, have you changed your mind on that?

Nope, my comment meant that the 3.2 will happily run using a 2.6 ecu and vice versa...

You need the ecu from the donor as it is programmed to the chip in the key...
