Car Alarm Problem?

Question:
I remember when I first bought my car, the alarm would go off if anyone leaned against the car. I just started noticing that it doesn't happen anymore. It goes off if I kick the tires though. Any ideas?

Help Im in trouble ! My mrs wanted a car for xmas I asked what sort she said something really racy & fast?

there is a mercury switch (vibration sensor) usually located in the engine compartment. At first the switch is really sensitive. After a while gunk and dirt clog it and it becomes a bit less sensitive. You could usually open the switch (protected by a clear box) and clean it out or just adjust the sensitivity ( with a screwdriver)

How much will it cost to replace a radiator on a 1998 Saturn?

there should be a bump sensor on most likely the brain of the alarm.. it shoudl have a rheostat , a tuneable sensor on it to adjust the sensitivity of the shock sensor

Yea the vibrating sensors are getting wore, just like anything else would. Have to keep them up to date.

Mercury Mistique question...?

It could be a wire is loose breaking the connection. I had a car that had been wrecked and after it was fixed they didn't hook it up right and every time the wind blew the blasted thing was going off.

How do you replace a alternator on a 2002 Kia Sondona?

There are two seperate sensors for better car alarms. One being a Shock Sensor, the Other being a Audio (Noise) sensor. Sounds like your shock sensor is not set as sensitive as it was before (Or its not working at all). Most alarms have an Indicator Lamp (The Red One) that will also tell you if something is wrong, by flashing a certian code (Long/short/short/long) etc. Set the Alarm and watch the lamp, if the lamp is steady (Blinking) then there is not problem, otherwise contact the company that made it.
