I have a Prestige APS25e car alarm in my car and recently I had a mechanic service the car. Now the car alarm is acting in a mediocre way, sometimes it would self arm, other times it wont. Sometimes the car alarm chirps, sometimes it doesn't. But what I find strange that is happening, the car alarm would sometimes chirp for the locking of the car, but it wont for the unlocking of the car. Could this be some wire that is breaking? or could it be that I have to carry the alarm for repair? I have also noticed that under the steering wheel, there is a black cable with about 5 other black cables inside of it, 3 of those black cables look like they have burst off of something. These black cables run towards behind the stereo and what seems to be into the engine if I am not mistaken.
