Denso used to make a 3-button remote with FCC ID HYQ1512R that goes with factory keyless entry systems used on several Honda, Acura and Isuzu vehicles between 1998 and 2004. The system paired with this keyless remote was used by Honda on 1998, 1999, 2000, 2001 and 2002 Passport vehicles. Acura systems using this keyfob were installed on SLX vehicles for the 1998 and 1999 model year. Isuzu used this system on many Amigo, Axiom, Rodeo and Trooper vehicles between 1998 and 2004.

Unfortunately, Isuzu is no longer in the car business in North America and Honda has discontinued sale of this part, making it more difficult to find. Remotes Unlimited does have a few left in stock.
This remote is user programmable for all applications.
