To reset the keyless entry on a 2002 Suzuki XL-7, first, insert the key into the ignition and turn it to the "On" position without starting the engine. Then, press the lock button on the remote within 5 seconds of turning the key. Repeat this step for each remote you want to program. Finally, turn the ignition off and test the remotes to ensure they are functioning properly.
