Review on Keyless Remote NHVWB1U521 NHVWB1U523 Instructions by David Dortch

Just received the keychain. Went outside to my son's 2002 Honda Civic EX, programmed to 30 seconds, runs like a champ! To program: put the key in the ignition, turn the key to start the car (no need to start the engine), immediately press the lock button on the key fob, turn off the car. Repeat three more times in quick succession - the fourth time the key fob locks the car. Watch YouTube videos if you want to see how the programming works.
