    Key Remote Problems

    Is this the dreaded dodgy contacts problem???

    About 2 wks ago my fob started playin up so I replaced the battery - resync'd it as usual and all was well ..... or at least i thought - an hour or so later try to lock/unlock car and nothing... had to use key in door then resync remote etc.... again all was fine for a short period of time ...

    the same thing has happened ever since and its still playing up.

    9 times out of 10 i have to manually open the door with the key

    my spare remote (which incidentally was the main one for previous owners judging by the wear on it) is pretty much the same....sometimes it works - sometimes it doesnt.... unfortunately i cant use this key as the key part comes away from the main body of the remote as the locating tab is worn.

    I suppose Ill try a new battery in the spare remote to see if the problem goes - if so then the fault would lie with my main key and possible worn contacts.... Would this be a fair assumption???

    If so, where are the contacts in the key and what part exactly am I to be looking for to fix? Any pics would be helpful


    OR

    could it be a more serious fault in that the fault lies with the car itself and not the remotes...

    Car is a 98 (R) Astra G for those who arent familiar.

    Thanks in advance ppl

    When you open the key up, make sure that the battery holder is still connected to the key. There are 2 legs which go from the battery into the PCB and they are very weak, I have had to repair both of mine.

    Hi mate in my experience it's the contacts of the battery connector that connect to the circuit board,poor soldering on VX's part,any time the battery is replaced the solder joint can give way and causes intermittent connection,Just resolder to rectify

    Here are some pictures of what I mean, Have used a few strands of speaker cable for mine. Ignore the poor skills, the soldering iron was too hot and too big for the job
    The legs can easily break if the keys are dropped as well (as mine did)
