03 M45 Remote door lock/unlock

[Gene Ln]

I am in need of the door lock/unlock part of the key.

I don't need the transponder portion of the key here are some pictures of the actual part

That might be hard to find even on a place like eBay...you might need to buy the whole thing. Either way you'll likely need a reprogram.

If you haven't tried yet, you can try using the K70206 AR200 0301 part number to see if you can find just the motherboard.

Ya reprogramming these isn't too bad, the transponder to start the car is the difficult one, These can be done at home there is a manual procedure as well as the computer one dealer would use.
I was hoping I would find someone that has lost the transponder out of these.
