Clifford is as hard as any other alarm is to install . I'v installed Clifford and it was about a 8 out of 10 scale to do. Most car alarm shops install the alrm for about 50 bucks with an ad on for actuators for the keyless entry system. I prefer Alpine alarms . They have the Blue LED light that looks great and they offer all kinds of upgrades,but Clifford was and still is just an alarm company.
