If anyone can help me... I would appreciate it. I got a 2000 Protege ES. Lately I've been coming back to my car... and the doors are unlocked. I know I engage the alarm when I get out the car, but I come back and the locks are in the up position.
It should stay locked... especially since the alarm is an auto engaging one even if I left it open. The funny thing is this only happens sporadically. So I can't figure out any logical reason.

The question I have is, could this be an alarm problem (I had it installed after purchase) or is it a Protege problem? I need to know so I can go to the right source to have this fixed.

 

sounds to me like it's an alarm problem. you might have it taken back to the place that you bought it from for them to atleast look it over.. tell them whats going on with it. see what they say.

 

Thanks. I called the alarm guy and he says he never heard of this happening. But, I'm going to take it in and have him reset the alarm. I hope this works. I'll let you guys know how it goes.

 

But even if someone elses remote disarmed/unlocked the doors, I know in my P5 if the doors are unlocked but unopened, it will relock the doors. This is not happening in his case.

 

Well I took the car back to the guy who installed my alarm. He reset the alarm and I thought it worked. but, I came out the other day and once again my doors were unlocked... and I am Certain I engaged the alarm when I got out of it. I'm beginning to think its cold weather that does it.

The guy suggested I replace the brain, but I think I might need to replace it all.

What do you guys think?

Any suggestions?

p.s. I know its the alarm because I sat in my car one day, engaged the alarm and unlocked the door... sat in the car for a while and got out. The alarm went off. When I return to my unlocked car, with the alarm previously armed, the door opens and no alarm sound.

 

Disconnect the alarm (by pulling the fuses or unplugging the brain) see if the problem persists.

what brand of alarm is it? and is the shop MECP certified or of good caliber experience?

 

I'm not sure if he is MECP certified. I doubt it since he is a cop that owns the shop and does the work as a side job. He seems to do a decent amount of work in this area though. (I.E. alarms and stereos) Its an Extreme alarm. Should I disconnect and reconnect the brain or simply disconnect it? Or should I simply get a new brand of alarm?

 

Found a solution. Just thought I would post in case anyone experiences this. The problem was bad wiring job. I went somewhere else and had them check out the car. Now I have a clifton alarm installed. Its working much better. But there was something that the previous installer did not do wiring-wise that caused this problem. Something to do with the amount of pulses required to send a signal to the alarm. I will never go cheap on alarm install again.

 

Well, you just learned rule number #1. An alarm is only as good as the installation.

 

True , thats why alarms cost loads to install $$$. Installation is almost as much as the price of the alarm itself.
