Vauxhall omega '95 on a "M"
No remote locking, and she's done 180,000 miles.
Supplied with only one key, which has worn to a nub, so couldn't get a new one cut (despite 9 attempts by "timsons" - gotta love that guarantee)
Then I snapped it.
one trip to the scrappie later.
I've replaced the drivers door lock and the ignition barrel but car is refusing to start - it turns over, just won't "catch"
I've got the remains of the original key on the key ring - the key to match the new ignition barrel still has the chip from the scrapper
Would this be interfering with the chip on the old key?
Am I better off getting a new key cut, and programmed with the original chip code?
Is it just a matter of replacing the original transponder sensor (from around the keyhole) with the one from the scrap yard car?
or can I take the wrong chip out of the new key (I'm assuming it's under the red bit of plastic) and tape the old (broken) key under the ignition barrel?
or something else entirely?
