remote issue

ok, i've spent all morning looking here and on e46 for an answer to a problem that started today.
it is an 02 330ciC, that is FULLY EURO CODED. i have 3 master keys, but this morning, none would unlock (or lock) the car, open the windows, open the trunk, or drop the top from the remote. i know 2 worked yesterday when i parked it. ALL THE BUTTONS inside the car work fine for each feature. and the gas door does lock and unlock with the key in the door. so do all the other keyhole functions. i looked at gm5 programming and it is intact. all the keys start the car. but none of the remote functions work on any. i already tried re-initializing one of the keys but it didn't help. i popped that key open and checked the batt and it is fine. what next?

solved

i disconnected the battery for about 30 min to reboot the car, tried again to re-initialize the fobs. this time it worked. before rebooting the car, it would go thru the motions correctly, locks would click, but after re-inserting the key to leave program mode, and removing it again, the fob didn't work again. i did this 1/2 a dozen times before rebooting, something would not hold the code until i rebooted the car.
so, if you have had no luck doing this, try disconnecting the battery for a bit and try it again. it worked first time after.
hope this helps someone.
