GM secondary anti theft device

[Avalanche Krazy]

Hi Everybody,
I'm having a problem with my 2013 avalanche I'm hoping someone can shed some light on. My 2013 came with a secondary factory anti theft alarm that goes off if the truck is jacked up to steal the tires or to be towed away. I purchased this avalanche from out of state about 4 months ago and not long thereafter realized that the alarm would go off periodically for no reason. If I got out of the car and used the remote to lock it and set the alarm sometimes it would go off within 10 to 15 seconds as if someone was breaking in. I took it to the dealership and paid for them to replace the alarm module. When I got it back within about 3 to 4 weeks it started going off again. Sometimes it would be my fault for parking in a parking spot that was maybe not completely level but other times it would go off in a flat parking place or my driveway. I have returned it to the dealership and they are going to order another alarm module in case the one they just installed was bad but they are at a loss as to why this would happen. There doesn't seem to be any kind of Adjustment to the sensitivity of the alarm. If this new part does not completely stop it my only option is to disconnect it because it will continue to alarm and run the battery down. It was at the dealership all weekend and when I came to pick it up on Monday while they order the new part the battery was dead from the alarm continually going off. When the key is turned off a message on the dash says press check to disable alarm. I can do that and that alarm will not go off but I don't want to have to disable it every time I get out of the truck, has anyone ever run into this problem or have any ideas?? There are no TSB's that we were able to find on this alarm system. Any help would be appreciated.

Sorry, I don't have anything to add that would help with your issue.

But, I was reminded of an alarm story of my own.

The key fob for my 2003 Avalanche has proven to be fairly sensitive when it comes to setting off that truck's alarm.

I have fished around in my pocket for my pocket knife and have set off the alarm many times, by accident.

Sometimes, I just have to move just right and the alarm button on the fob gets hit and sounds the alarm.

Now, I keep the keys for each of our vehicles on different key fobs since I don't care to carry around any more keys and fobs than I am likely to use at any given time.

I got over hauling around a big wad of keys and fobs a long time ago.

However, sometimes I have a need to shuffle all of our vehicles around to get to things in our garage or to allow me to work in the garage on mowers and such.

Last weekend was such a time.

I had just managed to get the Avalanche backed out, the 2004 EXT backed out and parked on the drive and also my wife's 2012 GMC Acadia.

The mower I was working on was now sitting in the shade in the garage.

Then, out of the blue, the alarm on the Avalanche started going off and I began fishing around in my pocket full of key fobs to find the right one to shut off that alarm.

I managed while feeling around for the Avalanche fob, to hit the alarm buttons for the other two trucks and set them off, as well.

All three trucks were now out on the drive just wailing away.

I just gave up and went back to working on my mower.

I'm sure my neighbors are used to this nonsense by now and just shake their collective heads.

Here's my secondary alarm, when it goes off it ALWAYS scares the burglar off..

One cheap solution to that might be to grab a couple "key fob protectors" which might help keep things from contacting the panic button depending on the design.

Also, car alarms, for what they are, are pretty useless unless it's you responding to it. People set them off on themselves all the time *cough* so no one pays attention. Its a boy who cries wolf issue. They're more of an annoyance than they're worth.

As for your issue Krazy, id check all associated grounds and power delivery to the alarm. ( a random disconnect would probably trigger it) I'd also check all of your locks and door handles to make sure they're working inside and out just in case.

You are correct about the "Cry wolf" thing.

One of my neighbors set off his ADT home alarm accidentally one afternoon and no one even flinched.

I have been known to purposely set off my car alarm on a large parking lot if I misplaced my truck.

I can find the truck and no one else even bats an eye.
