Is it possible to change the keyless entry beep/buzzer sound? i saw one parked (its an rdx) in a safeway store and heard it when the guy driving it unlocked it, it was different, sounded like those you hear on a lexus or porsche.

i was just wondering if there was a kit or something available that can do that...

 

He probably had an aftermarket alarm installed. There is no way to change the factory keyless entry beep.
