So I got a Matrix 2.5x installed and am not all too thrilled about it.

First, the alarm doesn't always unlock the doors. This is really irritating since it has the auto lock on startup. If I hit arm it will lock the doors, then press disarm and nothing. It happens about 1 out of 10 times. Pressing unlock multiple times does nothing either. It just won't work for a few hours, then later it is fine again?? I think I remember other people having problems with the door locks, but it's hard to find with the current search.

I got the proximity sensor which seams a bit flakey as well. For some reason it chirps if anyone passes by either of my front fenders. It's fine everywhere else though, you can even walk by the door and it won't chirp. The sensor is mounted in the glove compartment. Any idea why the fenders?

 

Sounds like a programming problem between the remote and the alarm. I have the same system and it works perfectly. I would say that you either need it re-programmed or maybe a new remote device. Do you have the two-way communicating device?? I think we have the same setup with the exception of the proximity add-on.

Thanks, I will just have to take it back to the shop I guess. This car has been one electrical nightmare after the other.

I noticed it almost always happens in the morning then works again by the afternoon. The posts I found referenced it not working in the cold, but that was with the factory alarm and no one presented any solutions.

 

These things happen---not just with Clifford.... CLifford is top-notch hardware, just think of it as a computer that is having problems---machines break all the time, but once you get it fixed, you will have the peace of mind of having their system guarding your car.

 

I used to install alot of Clifford alarms. I've found that they've always been a bit flaky. Very senstive to voltage and the brain easily gets "confused".

If I had $1 for everytime I had to reset one of these alarms. I would be a very rich man, but unfortunately, I always had to reset them for free.

Don't get me wrong, they are decent alarms, they work most of the time. One thing that we did notice, was that Cliffords seemed sensitive to high heat. If you let your car bake in the sun for a few hours, the cliffords acted funny sometimes.

As for the proximity sensor. I have never installed them in a glove box. The positioning seems wrong for that. Prox sensors were designed to be centrally located in the car and typically someplace low. If mounted to high, then they overshoot their optimum sensor area. (thus, detecting things out past the bumper or going really wide and triggering when somebody walks by).

preferably, it should be mounted in the center console, low and directly atop of metal. This helps create the "ground plane". helps stabilize the signal.

not sure if this helps at all, but thought I toss in my 2 cents.

 

Yeah, Kronos pointed out to me that the sensor is directional and they had it facing foward... So I layed it down in the glove box and it helped a little. I originally told them to mount it in the center console but they claimed there was no room and installed it in the glove box without asking...

I saw some other installs on here where people removed the plastic casing and slid it under the armrest, may give that a try this weekend. As for the locks, I will take it back in tomorrow and have them look at it. Unfortunately it starts working again by 8:30am and they don't open till 9am.

 

yeah, I haven't looked under the center console, but taking off the prox sensor case is pretty common thing to do. if you get rid of the case, chances are the prox sensor will be half of the original height.

good luck.
