I opened mine couple months ago to change the battery...just wanted to mention that no initialization is required after changing the battery....worked straight away.

I was not aware that this could be done? This should be added to the DIY!


Thanks

i DON'T HAVE THE PROGRAM OR HARDWARE NEEDED , SO I WON'T BE PROGRAMMING IT .
BUT IF YOU KNOW SOME 1 THAT HAS THE GT1 UNIT I WAS TOLD IT COMES WITH
THE HARDWARE ( KEY HOLDER ) NEEDED . I HAVE ALREADY TALK TO SOME 1 HERE IN L.A.
THAT CAN PROGRAM THE KEYS .& HE SAID HE THINKS HE CAN ADD IT AS KEY 1 .

HERE IS ANOTHER LINK TO A COMPLETE KEY NEW FOR $74.99

Im in the LA area as well, let me know if he can program the key for you, also- Do i need to buy the key transponder as well, or the second link to the bmw key itself is good enough ?

you can just buy the key in the second link .
I am not getting any key's made , i was just
looking into the possibilities of re-coding
a used key . The guy who i have talked to
has done several new key's for a friend .
So im sure he can still do a key for you .

I need a spare key made and have my original key fixed. The unlock button does not work. It feels like a broken piece underneath the actual unlock button. Can you send me the contact information for your buddy who could/would make a replacement? Thanks for your help!
