New Key and still doesn't work.
 

X5 2002 3.O
I thought it was the key not working. I went and I bought a new Key but the same problem still doesn't disarm or arm nor opens the doors or trunk.
I have checked on fuse # 20,24 and 60 as stated on the glove compartment for the central locking system.
I don't want to bring it to the stealer to have it look at it because it might be a minor step that I am leaving out.

Anyone with any ideas?

Did you reprogramm the new key? If not done so...

Agree RE: programming....The dealer you bought the key from should have programmed the key (s) as part of the cost of the key when you purchased them (it).

I have been really busy so I had my friend just pick it up and I though it was already program. So I guess I have to wait till Sat. go down there and ask them to program it for me. But, it doesn't seem that hard from the link above.
Will try and post result.

Yes not that difficult...but the new key has to be programmed to/with the existing key and vehicle...

I have tried both method on this link and still not good.
