OK, so after accidentally putting my key through the wash and scaring myself silly, thought I had better get the spare working. After reading about charging it up etc, drove around this morning with it next to the working one. I also saw about trying to start car with working key next to spare in the ignition. Anyway nothing works?

My spare key will lock/unlock the car with the fob - as normal. However, when you put it in the barrel, other than realizing there is a key in the ignition if the door is open, it won't even turn in the barrel. Looking at the key, I cannot see any differences in the actual key between the working and non-working, so I'm a bit surprised.

Is this the action of when a key needs coding? I would have thought it would have least of turned in the barrel.

I have an IID tool if it needs coding.

The key should still turn just like a traditional key.

Holy thread resurrection Puff!

Second key has never been a priority for me but I found it the other day moving house and it ended up with the key I use. I decided to try it again, so took them both out. Second key unlocked the car fine It goes in the ignition and then won't turn However, if I put the other fib next to it, it works fine! So therefore it must have become unprogrammed for the car!

I have an IID tool - how do I match the second key to the car?
