Key wont work !

Hi everybody,
my first post since joining this forum.
just bought a '98 C240 elegance - well pleased with it.
Anyway -
Had a problem the first time the wife went to drive it when she siad it wouldnt unlock!
Eventually i used my key to unlock it, she got in and tried to start it and it wouldnt start, my key started it fine.
Faulty key! so a trip to the dealers (or stealers as i see they are affectionately known) they kindly put the key on a tester (didnt see them do it) and said the key was faulty, a new one would cost £105 +vat.
So i went straight to this forum and did a search.
there was an entry from Joe Bloggs where he said to leave the key in the ignition, and see if the keys code aligns itself with the car,
after 30 mins i took the key out, and it worked!!:grin:

So the stealer tested the key - yeah right -
if anybody has a similar issue i would try everything before buying a new key, seems they may be easy money for them.

A dealer should always try to sychronise the key before ordering a new one. But on a car that age worth getting a spare cos it probably won't last much longer

Interesting point here, there is a coil known as a transducer around the key and this transducer recognizes the key, if the key did start to lose a lttle, then maybe it can re energize the key.

Update,
I took the key to a dealer, and they said it was faulty and i would need a new one at a cost £140, and matched to the car.



So i tohught i try ot resync first before parting with all that cash, and guess what.......it worked.

I left it in the car for 30 mins, went back to it, removed it, put it back in, and it started!
And saved £140 in the process.
Moral, try everything no matter how obscur it may sound, it could save you loads
