TOPIC: "My Code Alarm 2-way remote will only lock and unlock my doors...and the screen on the remote keeps displaying "Zzz" on it...I think this means "sleep mode"...but I don't know how to take it out of this mode?
REPLY: Try: turn your ignition ON (do not start the vehicle), look up at the systems' antenna (which is probably mounted at the top center of the windshield on the glass behind the rearview mirror)...see if the LED light that is built into the antenna lights up solid when you turn the ignition ON (not flashing)...if it is, press and hold the button that is also built into the antenna until the LED turns OFF then release the button...now try activating the remote starter. Maybe, somehow, your system was put into valet/service mode.
