factory alram (remote)

picked up a factory alarm system out of the wrecking yard but it didnt come with a key fob. i was told by stereo shop it had to be an acura fob. i called acura and its been discontinued. he also said that they have always been made my Kenwood, and may be able to find a Kenwood fob that would work. Can anyone clear this up? what can i use?
thanks
