Do you need to just resync your remote due to a battery replacement in the remote or car itself or do you need to program a new remote?

I had to replace the body control module and now the keyless remote does not work. I assume that the keyless remote needs to be reprogramed.
Expert:  Shawn replied 8 years ago.

Replacing the BCM will require the remotes to be reprogammed. The problem is that you need a scan tool with the proper software to perform the programming. Here is the procedure for reprogramming if you have access to a tool. If not you should put a call into a local garage that does diagnostic work or the dealer. If it were just a battery change you could resync without programming.

IMPORTANT:Up to 4 transmitters can be programmed. Do not operate
or program the transmitters in the vicinity of other
vehicles that are in the keyless entry program mode.
This prevents the programming of the transmitters to the
incorrect vehicle. The order in which the transmitters
are programmed is important. The first transmitter
programmed will be transmitter #1, and the second
transmitter programmed will be transmitter #2. Use care
to program the transmitters correctly.

Thanks, Do you know if the miles can be reset to the proper miles on the car after replacing the body control module?
Expert:  Shawn replied 8 years ago.

I believe the TECH 2 tool used by the dealers can do this with a resync with the PCM.
