2000 Pontiac Bonneville Keyless Remote Battery Replacement Programming Help

Just replaced the battery in my keyless remote. Having trouble getting it to work again. Is there any special way to re-program the remote once the battery is replaced? I already held down the lock and unlock down at the same time for over 10 seconds and that didnt work. Thankss

IIRC this may have to be done at the dealer with a Tech II scan tool as you have remote 1 for driver 1 and remote 2 for driver 2... So the dealer may have to take care of this for you..
