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

THE HARDWARE ( KEY HOLDER ) NEEDED . I HAVE ALREADY TALK TO SOME 1 HERE IN L.A.

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!

Hey PAPER and everyone else, I really appreciate you sharing so much knowledge and helping everyone out. Im located in OC and my key works except the unlock button-I have to use the hard key to get in.. The buttons feel totally normal. I was wondering if there was a way to fix my key? Maybe I could open it up like you did, but it's my only one so I don't wanna mess it up. Also I saw some used OEM uncut keys on ebay for less than $100. I want to buy one as a spare and have someone program it to work with my ride. Does anyone know anyone in SoCal that can do it? The dealership wants like $300 for a new key and told me no locksmiths can do it for theft prevention reasons BMW has created..I don't believe him and Sterling BMW customer service wasn't that great.. They treated me like I was a nobody even though I have a clean 2003 745i with only 91k on it..
