To reprogram the key fob for a 2002 Mercedes, first, ensure you have all the keys you want to program. Insert the key into the ignition and turn it to the "On" position without starting the engine. Press and hold the "Lock" button on the key fob for about 5 seconds, then release it. Turn the ignition off and remove the key; the fob should now be reprogrammed. If you have multiple fobs, repeat the process for each one.
