New Diamond Key - Won’t Turn Ignition
 

Just got a new diamond key from the dealer ($265) and the key will open the doors when inserted into the lock. The key will not turn the ignition. The ignition is locked and won’t budge at all. Is this a key issue or do I need to do something?

Connected the battery to jumpers to make sure the ignition had sufficient charge but still no luck.

Does the old key turn the ignition and unlock all doors when inserted?

It sounds like it was programmed to talk to the FZV (wireless antenna) correctly, but not cut correctly. The key should turn if it is cut correctly.

I have the same thing but I need just to wiggle the new key a bit the first time. The problem is that the lock cylinder and the original key are both worn together and the new key is sharp and catches on the worn lock cylinder. Lube and wiggling will probably do the trick and maybe wire wheel to round off the new key might be the answer but I don't know if I would risk that, maybe talk to dealer and/or locksmith.

the old key worked completely and was also ordered from BMW as a replacement

do the original keys have a notch on each side cut near the top? i can’t remember if that’s an e46 key i’m thinking of or if it’s an e53?

i’ll try it a bit more

Don't forget that you may have to move the steering wheel a bit, would be same with old key but sometimes the brain blocks stuff like that out when you get focused on the new key not working.

i’ve been fidgeting with it for a bit but no luck. worst part is the truck is not at my house, it’s parked at my friends house kinda far away - i’m replacing a lost key :rolleyes:

That sucks, maybe a locksmith could buff it a bit for you ?

I use a product called Viscotene on locks but almost any kind of spray lube should work at least to get you going.

good idea, i’ll bring some when i come back - thankfully it’s fine being parked in front of his house.

If you haven't tried wiggling the steering wheel yet...try that. Could be parked with tension on the lockout mechanism.
