1998 camaro Unlock

Ok my dad has a 98 camaro and he tried to install my old clifford concept 200 alarm on it. I had relays on my blazer and he didnt put relays on the camaro. The clifford alarm can be + or - out for the door unlocking. everything works except for when you unarm it it wont unlock the doors.unless you arm it then unarm it within 30 sec then it will unlock the doors. he has the wires hooked up on the passenger side where the go under the dash. I told him that he needed to tap into the wires at the motor. my question is does he have to put relays on it or not.
