    Ts astra remote central locking wont work

    Hi all. I have researched this problem done everything i can and it still won't work.
    I just put a new battery in the remote inserted key into ignition turned onto accessories held the lock button in with doors closed nothing happens. Tried pressing and holding both buttons doors open etc still won't work.
    Have no idea what to do next. It's not a massive problem but would be good to have it work as it seems everyone else's does.
    Any help would be welcomed. Thanks.

    battery tray may have come apart in the key. Open the case, fold up a piece of cardboard and put that on top of the battery (so it pushes the battery down), close the case again and retry.

    You'll need to re-teach the remote by putting it in the ignition, turning to position 2 (the one where all the warning lights come on) and holding the unlock button. The car will lock and then unlock and your key should work again. But as dutchy said stick some cardboard in there otherwise you'll keep having the same issue.

    Thanks mate. As I said in the first post key is in ignition set to accessories one before engine start holding open button down nothing nada will not resync, tried pressing both buttons holding both buttons doors closed doors open nothing. If the red lights working when I press the buttons surely the battery doesn't need cardboard over it as its making contact fine other wise the light wouldn't come on. Can it be blown fuse?, it just won't resync, I read my manual it says to do the same thing that's been suggested.
    "Switch on ignition system will then remain in synchronisation mode for 30 seconds. Briefly press any button on the remote control unit when the unit is in the ignition. The central locking system locks and unlocks to show that the remote control has been programmed". Still will not work....

    Sorry, are you putting it in accessories or ignition on? You've stated 'one before engine starting' which is correct... 'accessories' will not do though.

    Taking away the confusion though, just start the car up and press the button as soon as the engine is started. If it doesn't pair then, then there is another problem.

    Ok cheers ill try what you said tomorrow morning. If that fails
    What could be the other problem?, iv read alot of google searches on this topic and everyone ends up getting it to work after its re synct, I seem to be an odd one out. I basically got the car a few months ago the caryard has to sell the car legally with an imobaliser I thought the imobaliser works with the central locking keypad button which I now know isnt the case so my car has no imobaliser and the central locking remote wont work. Can it be a fuse?, i think I have to remove the plastic covering near the hand break to get to them other wise i would have allready checked that. Other then that I'm lost for ideas.

    Has that key FOB ever worked with your car? Or did it just stop working after you replaced the battery? If it has never worked with the car, it will need to be programmed with Tech2/Opcom. I can do this for you if you live close by.

    If it has worked with the car before, it won't hurt to check fuses but I doubt you'll find anything if the central locking is still working. The OBD2 connector is near the hand brake. The fuse box is behind the compartment at the driver's right knee.

    Hey thanks Delemonte. I purchased the car around 2months ago and it never worked from the beginning.
    Thanks for the offer but I'm in Perth Click here to enlarge. Well I guess checking fuses is out of the question then as you have explained it well. It's strange because the keypad its self is worn to the sh*t either the open or lock button has no rubber on it, its down to just the little round button so that makes me think it was working and used until recently. In the manual it says to replace the FOB at 120k mines on 115k. So I guess the only way I can get this working is to get jipped taking it to holden or find someone that has one of these OBD2 devices?. Their was the inspection light on when I got the car but I never had the warning light come on and I cleared it and it hasn't come up again any chance the FOB failing would set off the inspection light?.
    Thanks again.
