Title: key casing replAcment.....fault????
Post by: kam on November 19, 2012, 10:35:33 am: Hi guys I changed the casing on my worn key today, I also removed the old blade and fitted it into the new holder that comes witht the key, changed over all the internals, since then the vehicle starts for a few seconds then cuts out and comes up with imobalizer active on the clocks.

Have I done something wrong or do I need to have the key coded, it was working fine before I changed the casing and swapped the blade......any help would be great thanks.

If you haven't done that, that may be whats causing your problem. Do the buttons work to open your car remotely ?

did you transfer that over?

Ed to the recue once again, many thanks.

I found good old superglue also works rather well to stop it moving :signLOL:

eBay - lots on there. About £5 or a decent non genuine one, about 4x or more for a genuine version. I have bought a couple of non genuine ones and they are no different to the originals

Post by: Veee-dubber on November 21, 2012, 06:31:03 pm: eBay £5 all in - piece of cake to change as well! You do however need to tape the transmitter in as it's not as snug a fit as the oem ones!
