my car was recently keyed so i decied to up the sensitivity on the motion sensor i turned it all the way clock wise like the owners manual said to increase sensitivity and re armed the alarm i then shook the crap out of my car to set off the alarm nothing happened so i adjusted the sensor all the way back the other way in case i miss read the instructions and repeated testing nothing i also checked the programming for the alarm activation and everything was as normal could my shock sensor just be bad i need help

 

It may depend on where the sensor is mounted. You want it solidly mounted (screwed in) to a piece of metal as close to the frame as possible (on inside of firewall is a good place.) If you just have it hanging or tied to something it may not work well, and if the car is keyed I don't think a shock sensor will pick it up at all, and sorry to hear about your car.

In fact... I have a 95 with a shock sensor and some kids threw a f*cking HAMMER at my car and hit the roof... since the roof is fiberglas though, it didn't transmit the vibrations and the alarm didn't even set off. We did manage to catch the kid on tape though, and got $1000 cash for the roof and the drivers mirror he broke 2 months earlier... rotten bastids...

 

thx for the info the shock sensor is the stock one and is firmly mounted above the rear pasenger wheelwell
btw what type of set up did u use to catch the kid on tape since i might go that rought to catch any future vandals

 

Well what I had an old VHS camcorder that I set up in the front of my house (it was actually inside the house,) and it recorded looking out the front window. I'm in the process of buying a closed circuit tv camera, in which case it will hook directly up to a vcr to record, and will be mounted to the outside of my house.

 

I had my shock sensor turned up a lot, but all the loud trucks and stuff that drove by set it off, and it sucked because my remote would start screaming at me, (I have an Ungo that pages). So I turned it down, but now it only goes off when I hit the windshield or something.

Anyways, I think most shock sensors will not go off with just pushing the car up and down. Most of them (as far as I know) need a sudden shock or a fast vibration to set it off.

To warn keyer's, get a proximity sensor and turn it up all the way, but then the alarm will beep at anybody who walks near your car. I got a proximity for mine, but unhook it in the winter because I never take my tops off in the winter. When it is plugged in, I try to adjust it to only sense when somebody is leaning against my car, but it never was consistant, and always gave false alarms. But it is good for when you leave your car with the tops off.
