Honda makes one for it. you can buy an original Honda part and have it installed. it only works on automatics for obvious reasons. also, its impossible to unlock the doors while the engine is running in remote start mode. you must stop the engine, unlock the car, and then start it again normally. this is to prevent theft. for manual transmission or to get rid of the unlock issue, you need to go aftermarket. i would reccomend computstar or DEI.
