Default How did the theif bypass my alarm????

I went to a race spot and parked my car about 50ft from where they were racing. As I was standing there, I was trying to keep an eye out on my car. I notice some people parked their car by mine and thought nothing of it.

I say no later that 15 mins, I was ready to leave and started walking over to my car. From a distance, I was wondering why my remote wasn't working. As I got closer, I NOTICED MY CAR WAS RUNNING!!!!!
When I got in the car, I saw the the ignition was undone and I knew what was up.

Although I'm thankful that I still have my car, I can't stop thinking how the hell the theif got around my alarm without it even chirping.

The alarm is called M.A.T. It's pretty much a basic alarm with a starter interupt. When you disconect the battery, as soon as you reconect it, the alarm will sound. The alarm has a valet button.

I did a close inspection and the only thing that the theif touched was the battery. My alarm is still in full working condition. The thief didn't even remove the lower dash panel so I don't see how he could of even messed with the alarm.

Does anyone have any idea how he got around the alarm and started the car with out it even making a sound? I want to know so I can protect myself a little better.

That says it all right there. I bet you don't have enough sensors to properly protect the car. Are all doors connected to the alarm with pin switches (either OEM or aftermarket)? Is the hood protected with a pinswitch? When was the last time you tested the alarm to see if it even works?

Open hood. diconnect batt. bust ign., turn on, hook up batt.,[ silent power up] start car drive away.

You are very lucky, the car was running so they must have been very close by.

I think I know how it was done.

It must of been a two person job.
1. Grabbed hood release from outside car. No arming pins on hood so alarm didn't sound.

2. Once in hood, they disconected the battery. At this point, anything could of been done and the alarm wouldn't of made a sound.

3. Door was slimed and they entered the car.

4. This is where the second person would of been needed to do it as I describe.
One Person sood outside by the battery while another person was in the driver seat. The person in the driver seat pressed the valet button and when the other person connected the battery, the driver switched the ignition to acc and disabled the alarm with the valet button.


If they did it at the right time, the alarm would of only sounded for a split second. That probably wouldn't have been enough time for me to hear it over the racers.

Does this make sense?

Uh....

Why would they need two people? Get a universal key, put it in the ignition, push the valet button and turn the key, and voila! No more alarm. That's why you have a custom code instead of the preset valet switch.


Also, did you install the alarm or did someone else did? Most of the time, installers do not hook up starter kill unless you pay or ask for it.

Well, I know for sure that a key wasn't used becuase the ignition was apart.

They disconected the battey, but they had to reconect it to start the car. As soon as they reconect it, it would of went off. That's why I think they used two people because they could of minimized the amount of time the alarm went off.

I know the starter interupt works because I tried it.

Question!!

In order for them to press the valet switch they would have to be able to locate the alarm brain right?? What if they alarm brain is hidden?? and all the wires are soldered and wrapped into the harness under the dash, so u dont know where the alarm wires are, or where the brain is??

Not necessarily. The valet switch is often mounted separately from the alarm brain and connected to it via wires. Finding the valet switch and defeating the ignition lock will allow a thief to shut the alarm off, as in Stewie's situation.

What I've done in my vehicle is to mount a decoy valet switch in a location that is somewhat hidden. The fake wires run from this decoy switch to a location in the dash away from the alarm brain, further enhancing the deception. The real valet switch is extremely well hidden and would take a LONG time to find. I also added a hood lock and an interior piezo siren. I also have a battery backup siren. All this will really frustrate a thief.

Even if you gave 12v to the ignition, you will still have to disable the alarm some how. Because once the car was under power, the alarm would sound.

well, I'm not alarm savy so I'm sure what you mean by last mode power up, but like I said a million times before I know for a fact if you disconect the battery of my car, even if it's days later, the alarm will sound and the starter interupt will still be on. It's happen to be a lot of times when my car was sitting in my garage.

Just for your information, my alarm for sure ain't near the best out there, but in my opinion, it ain't half bad either. It does have a pin switch hookup, but this alarm was installed at the dealer for nothing when I bought the car and you know they don't do that stuff.

Also, this alarm has a battery backup, but it ain't worth a damn because the battery is five years old. Like I said, I have to step up my security a little bit.

Last mode power up, if the alarm is armed, and you disconnect the batt., and then hook it up again, 1sec later a year later makes no differance, the alarm will trip, if the alarm is disarmed, when you hook up the batt. it will not trip, and if the alarm is alarming [ say triggered by opening the door] disconnect batt., it stops,but when batt.is hooked up ,it will go off, and LED readback [if it has it] will read that it was the door that tripped the alarm, last mode power up.

Your alarm on the other hand, if I understand you, will trip when you hook up batt. even if it wasn't armed, so it does not have last mode power up. Very easy to bypass as I have said.

And I'm sorry to say if it was installed by a dealer and for free, it will be the cheepest unit they can get there hands on 94

I have a DEI alarm, Viper series. And i was told that when u arm the alarm, the starter kill module, has a switch inside that opens(unconnects), so that there is no connection, so the starter cant be used. And when i un-arm the car, that switch closes(connects) and now there is a connection. If u get my point??

Well i better look for my valet switch becaues i have been under my dash while installing my stereo system, and i didnt even notice it, let alone see any signs of a car alarm. which might be a good sign. Once they tried to take my car, they got as far as drilling the ignition out. But thats all. and this was in an underground parking lot, so im assuming they had some time.
