    I have noticed quite a few people have had the same problem as me with their remote key. So I put this together with some photographs of how I repaired my key and saved myself about $100 for a new key. Can be done in under an hour.

    THIS WILL ONLY WORK ON PRE-VS COMMODORES! (VR and earlier)

    All VS and onwards keys (and also replacement keys) have a sealed unit that will wipe the internal memory of the key if it is opened up. Anything ORIGINAL from VR or before will be fine.

    Gday

    Y does everyone keep saying that post VR keys once opened will wipe the memory? that is bull**** because read my thread in the how to's because i repaired my key for a vt 99, the only wy to wipe the memory would be to remove the battery, there is no circuit attached to the plastic casing that would cause it to lose its memory.

    My key works as it always did, only with a repaired button now :D

    Cheers

    Well, as far as the wiping memory thing, I was only passing on what the Holden guy had told me at the time. I assumed he would have known what he was talking about... but I don't own a VS or anything after that, and I have not repaired the key for one, so I have absoultely no experience in repairing them, and I have no intention of making out that I do. I simply thought that I wouldn't want to be responsible for anyone stuffing up their key and putting themsleves through a bunch of inconvenience.

    So anyway, go easy troops, don't shoot the messenger. :bop:

    I was just passing on what someone who should know more about these cars than me had told me. In the light of other people's experiences, it would seem that the Holden guy may have been wrong, and some people have pulled them apart without any issues. Forgive me for being cautious in that regard.

    As for the issue of the battery itself being flat, my battery was actually ok, but I decided to replace it anyway, considering that it was like $4 for a new battery, and I didn't want to have to rip the key apart again in a few months if it died, so I replaced it while I did the repair.

    Still working fine a few years later :)

    I called Holden too, regarding replacement batteries for my '96 VS key.. They told me that I had to take the key and the CAR to holden for re-programming... WELL...

    When i brought my car, for some STRANGE reason, it came with FIVE spare keys :)
    I did what any normal person would have done and played with one of them..

    I REMOVED the battery. Just to make the point, i left it out for TWO DAYS.

    I went to the store and got the same model battery, de-soldered the flat one and re-soldered the new one in place.. all this was then held back in place with 2 part epoxy..

    so i go out the front, try my newly repaired key and whaddaya know... IT WORKS.

    So in my own experience, what Holden are telling us about keys is utter shite.

    Oh.. I should mention this too: when I had the battery out of that key, i grabbed the key itself (the one that screws into the black button housing) and drove my car about 25kms.. Now, what was Holden saying about the immobilisers?? with just the key in the ignition there is no contact on those two metal whatsits near the keyhole, so the imobiliser should not turn off --> (effectivly the key is a very niclely shaped screwdriver, as there is no contact for the deactivation of the immobilser)
    so much for immobilisers on the VS...


    From what I have seen and played with, Holden VS's do not have any security when it comes to keys... Go ahead, change that battery :)

    Nice bit of investigative work there mate :)

    I would have thought that the immobiliser is switched off when you first unlock the car though?
    But yeah that thingy on the steering column is supposed to be a "key reader." Maybe those contacts are what's used to program the key to the car in the first place.

    could be..... maybe i am a skeptic tho, coz i'm thinking that there isnt a key reader system at all... just a bunch of bells, whistles, smoke and mirrors... but as i say.. i'm probably just a skeptic

    I actually thought the contacts were only to charge the battery in the remote? I didn't think there was any "key reader" involved whatsoever.

    If you leave a key in the ignition with the ignition switched on for 1hr and 30 min, you can then start the car and drive it home ( it's in limp home mode). it doesn't work the second time within 30 hrs. once you switch it off thats it for 30 hrs or so.

    With a full working key start the car switch it off again, within 30 sec insulate the key reader from the key contact (around the ignition) and the car should start and run.

    ok guys here you go ... the truth
    the immobiliser will stay disarmed for about 30 seconds, thats why you could start the car, try it when the red light is flashing, it wont run.
    the key will under no circumstances loose its coding with the battery removed
    the contacts on the ignition barrel read the key in case the radio frequency section is dead, the contacts are also used to program the key.
    the time out is provided to allow the car to be taken to get a new key programmed if it dies completely, it will work any number of times if the system re arms
    Basically there is a good immobiliser system fitted to these cars.
    try it out, let the system arm (red light flashing) insulate the contact & try to start it.
    Vt has a different system it needs to read a good key to go

    hope this clears up some mis-information

    And the truth shall set you free....

    Thanks a lot for such a good follow up Doctor Bob, obviously even the Holden guys didn't know all of that stuff. It's good to get the drill on this at last.

    When I got my VR, it came with the original one button keyhead, and an after market 3 button one (2 Buttons did absolutly nothing lol), the 3 button one worked perfect and the originals battery is dead or somthin cause remote doesnt work, but it starts car etc. Then i got thrown in the pool with my good remote now its rooted, the only thing it does is manually open doors but it will not start car or anything, and i cant afford to fork out $80 for a new one, but i want my remote central locking back, is there any hope for it? or will all the components be rooted cause of the water?

    normally if it stops working when wet it will not come good.the only way is to get a new one & get it programmed to the car

    Sorry mate you cannot program the key yourself, it will need to be programmed.

    Btw, where are you located at?
