Rebuilt Corsa keyfob- No programming needed!

Discussion in 'Corsa' started by Just Another Corsa Fan, Jan 3, 2007.

  1. If anyone is interested these are a few pictures of the project to
    rebuild a Corsa keyfob. Total cost was £18.50 and importantly NO
    PROGRAMMING AT ALL WAS NEEDED.

    The original fob had demised in true Corsa fashion. In the picture you
    can see the perished rubber and the switches after they were removed
    from the pcb.

    A fob was obtained from ebay which as it was listed as "brand new" I
    went to £16 +£2.10 postage for.

    When the fob got here it didn't work! Suitable feedback about yet
    another ebay rip off artist left but
    decided to carry on and try to rebuild key as the body of the
    replacement and its buttons did indeed
    seem as new. I suspect that it was faulty and was replaced by Vauxhall
    and the faulty one stuck on ebay.

    With the fob opened up the bit I was dreading. Could I get the old push
    button switches off or not?

    To my suprise, a quick dab with a VERY SMALL soldering iron at each end
    of the switch and they fell off!

    Removing the new ones from their pcb was just as easy and went on the
    old pcb no problem.

    Put it all back together using the new rubber housing and fingers
    crossed X! IT WORKED PERFECTLY!

    The equivalent of a brand new keyfob for just £18.50 with no
    programming at all needed.

    I'd only advise trying this if you are experienced with surface mount
    soldering or have nothing to lose. I.e. don't blame me if you **** it
    up...

    3 show my fingers holding a switch. You can just make out the sm solder
    connector.

    That picture looks like a bum holding it. Are you sure it wasn't your rear
    end?

  7. Thanks Mike,

    Here's a much better macro shot of the switch/button after removal
    showing the soldered connector.

    The pink stuff is my fingerprint.. (Not me arse!!)

    It really would be nice to source these switches/buttons. Anyone got
    any ideas?

    Camera is a Fuji S9500.

    In the UK, you can probably get them from Farnells
    http://uk.farnell.com/jsp/search2/b...063&Ntk=gensearch_001&Ntt=tactile+switch&Ntx=

    It might take a bit of searching to find exactly the right one amongst
    the hundreds of different types and sizes.

    Serves you right you should not have sold all those taxis

  11. It was costing me more to keep getting keys made for the taxis than
    what I was taking in fares! Vauxhall charge
    up to £160 a throw for one!

    Cost me £18 and that was only becuase I was fussy and waited for a
    brand new one. There's a bloody good and easy earner waiting if anyone
    wants to bother. I've even done what Vauxhall said couldn't be done and
    copied a key.
