To reprogram a Lexus RX300 key fob, first, sit in the vehicle and close all doors. Insert the key into the ignition and turn it to the "ON" position without starting the engine, then turn it back to "OFF." Repeat this process twice, then turn the ignition back to "ON" a final time. Press and hold the "lock" button on the key fob for a few seconds, and this should reprogram the fob. If this doesn't work, consult the owner's manual or a professional locksmith for assistance.

Car alarm in Lexus ES300 started going off at random when car was parked, not running. I changed the key fob battery (flat watch battery) with a new battery and it fixed the problem.
Lexus has to hook their computer to it to program the key to both lock/unlock and to start the vehicle.
You normally do not have to reprogram the key when you replace the battery. If you do you will have to contact your VW dealer.
You'll probably need to have this done at a dealership.

Take it to your dealership they would be the one to help you with that.
your key fob can only be programed by the local gm dealer.
