Hi - My wife lost her keys to our BMWs and we thought they were somewhere in the house. We tore the place apart looking for them, but after 2 weeks of not finding them, I ordered two new keys from the BMW dealership, one for her BMW and one for the X3.

I have instructions on how to get the new fob for each car to work with the car, but am having a hard time finding instructions on how to disable the lost fobs. Some sites say only 2 fobs will work, others say they can de-code the lost fobs remotely for like $160 or something. I just need instructions on how to disable the lost fobs if anyone knows, or is it automatic if the good fob and the new fob are in the car? I have the cables, the software, and have coded the cars before, so decoding can't be much different. Any thoughts or ideas?

Thanks!
