    A job for op-com or the remote on my key just fuBard?

    Before anything is said, i've tried a new battery & i followed the syncing description to the letter & still no joy.

    The actual key will unlock/lock the door. It'll also start the car perfectly fine. It's JUST the remote which wont lock/unlock the car (on the spare key). The remote on my main key works perfectly fine (albeit the battery is on its way out finally, but that's nothing).

    I opened the remotes up. Both have that weird shaped black chip in place.

    There is a difference though. The innards of my main (working) remote look all secure. As you can see from the following pic....




    The innards of the duff remote though aren't looking so secure. The battery housing has to be held in place by blu tac, or it just falls out.

    I wonder if the contacts to the PCB have snapped (i don't know how it's fitted, but i'm guessing some thin metal contacts??). This is my only guess & it's just a wild one at that.

    Oh, the pic.......

    Cheers dude. Having only ever soldered once in my life, which was in year 9 high school electronics, i don't think i'll try it

    What's that little black chip thing that's a weird shape? Will i need one from the new remote, or will the one i currently have be ok? I'm assuming it's needed.


    Get new remote, slap my spare key onto it & then program it with op-com i assume?

    Black chip is what the transponder communicates with, ie your immobiliser

    And yes, spare key/opcom will be fine

    Just had a look on eBay. The price for these things ranges a bit don't they!!

    Saw a few at a reasonable price, but they're without the silver topping that you can put your keyring round. Without that, you're a bit knackered for your keyring.

    Those i saw with the silver topping were about 3-4 times as much.

    Get a second hand key with the fob part and then use OPCOM to program it up.. Then put the new programmed fob on the top of your blade key with the little black chip and away you go!
    Have just done a set for my grandad 2 weeks ago using 2nd hand keys from ebay as his MK4 Estate came with one severally buggered key which wasnt working. Think the most he paid was £10

    When I bought my astra, the spare key had one contact broken. I only noticed when I went to change the battery and noticed there was some folded up card in there to keep it in place so perhaps you could try that?

    Send me your remote fob part and I will re-solder it back on for you. I just need the circuit board and the battery holder, you can hold onto the pastic fob surround so that you can re-clip your key back onto it so your chip doesn;t get lost.

    Just cover postage via a jiffy bag and the jobs a sorted.
