2000 Silverado Security System??

I just bought a 2000 Silverado, does anyone know what the factory security system consists of? I don't see a chip in the key and there doesn't appear to be any type of alarm or anti theft device, so what are the security features besides locked doors? Thanks

I had a 2000 single cab before I purchased my '04, and on that truck it basically consisted of this...If someone actually tried opening the doors from the inside by means of smashing the glass or entering the sliding rear window, the alarm will go off. Also, after you arm the truck, you have 15 seconds to unlock it using the key. Any attempt at unlocking the door using only the key and not the key fob after 15 seconds sets the alarm off. Kind of cheesey, but its a deterent. Now if GM would give us a kill switch and a key with a chip like the camaros and vettes, it would be better. :banghead:

Thanks TxNitro. A kill switch would be great, I'll probably see about something after market, I believe Chevy trucks are high on the car thieves' hit list.

I also installed a battery kill switch on my '04. Found a neat hiding spot under the hood, since I travel somewhat, I can kill all juice if need be. Of course, I have to re-enter my radio code and my alarm won't work but it can't be started by someone who doesn't know what to look for.

Dudes, you have it all wrong. All Silverados and it's sisters all have alarms and kill switches. The alarm is very simple and will only go off if a door is opened without unlocking it with either the key or remote. Now, the ignition also has it's own system. It relys on a special decoder that's loaded into the cyl, lock. When you start it with the key, it sends a special code to the BCM at a given time. This misleads many people because you do not see a "chip" in the key and that you can copy your keys anywhere and they'd work. Don't let this fool you. Trust me, I've been working on these systems for many years now. The system on these trucks has virtually been the same since '98 though the present. It is much better than those on the Z28 and very close to those on the Vettes.

Thanks for the input, but I'm still wondering how good the system is. I had a key made at Sears, then opened the door without disarming the system, the alarm went off, then I inserted the Sear's key and it started fine and the alarms stopped. So doesn't this mean that someone could break the window, and break into the steering column and start the vehicle with a screwdriver and drive off? I still don't see how the electronic security stops anyone from breeching the system. Thanks!

First of all, let me say that I have been doing auto electronics for 12 years. Factory alarms are crap. The car will start with the alarm going off as long as the key fits in the ignition. If someone was to jimmy the column let's say, with a screwdriver it would not start. Factory alarms lack so much; shock and motion sensors, IGNITION KILL and the ability to upgrade to remote start, window roll up, etc. For the piece of mind it is worth it to get an aftermarket alarm system.

I 2nd almost everything you say. There are SOME OEM systems that are alright but still, if they want it, it's theirs! There have been some high end Mercedes with some pretty stout systems like the "SmartKey" system is hard to beat. On the other end, I have yet to have a domestic car give me a problem. :lol:

Thanks guys for the comments, I think it's worth a few bucks to add some additional security it for nothing else piece of mind, since this vehicle sits outside, a couple hundred bucks or so for an additional systems add-on is pretty cheap insurance.

Dude, you're wrong. I have an '02 Silverado and no alarm. The message center never blinks "Security."

Maybe one of you guy can help me in this matter. I don't know what I did, but I changed the oil in my truck yesterday and started it up from the outside with the windows down and the door closed and it stated up for a minute and then shut down. The security light came on and now the truck cranks like bait caster reel, but wont start. I hooked up a snap-on scanner OBD-II and it pulled up a code saying anti-thieft security code was wrong and that's why the truck wont start. How do you reset this code. I also have a code B1001, something dealing with the airbag system. I can reset this one but it comes back when i try to start the truck again. It's a 2003 Chevy Silverado LX 1500. I tell you boy, I'm up Sh1t creek without a boat or paddle because I'm over in England. I had the truck shipped over frome Charleston South Carolina last December. If yall fellas can give me some advise, I would greatly appriceate it.
