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.
