another wierd key FOB thing

[taosx5]

Hey all, it has been awhile since I have been on here, that means things are working good - yeah! We have an 03 X5 4.4 owned since new (wife's car) The usual key FOB quit unlocking and locking doors. We have always taken the extra key every few months and use if for a few days to charge it.

The daily FOB quit working, still starts the car jus would not lock or unlock electronically. I took both keys and did the whole programing thing all within the 30 seconds. The extra key programs and works fine the old will not reprogram. I suspect something inside the key has worn out. Does anyone know if this is the case? Any clues? I read where someone called GM5 can repair keys but could not fine out much about what that involved.

Thanks in advance for any advice.
