The Excalibur car alarm system works with three basic components: transmitter, the status LED light, and the hidden valet button or switch. If one of these mechanisms fails to work properly, it may cause the alarm not to arm at all or arm at the inappropriate time. Some quick and simple troubleshooting will have you driving on your way and back to feeling secure in just a few minutes. Symptoms that the yellow wire is loose or not in a good position are: the alarm arms with the ignition key on, it doesn’t arm at all, or the valet override malfunctions and fails to disarm the alarm or reset its memory. A symptom of the valet button being stuck in the “On” position would be the alarm not re-arming after you retrieve your vehicle from being serviced.
