security lightcame on and car wont start!!!!! tried resetting pcm didnt do it how do i disconnect alarm????

 

Try a different battery. I had the same problem, and I just switched out mine with a buddy's and now everything works fine. Try that, and then let us know.

 

i just read in owners manual says my key could be bad, or do you think it could be my battery

 

If you put the wrong key into the ignition sometimes that will cause it to happen.

 

its the c\key that came with the car has worked for the last 30k miles

 

I thought that it was my key as well. It wasn't. Try your battery. I am pretty sure that is your problem, just like mine.

 

Any time the security light is on it means the passkey anti-theft system isn't reading the right resistance value from the key. GM passkey systems are notorious for "forgeting" their values. Try another key if you have one then try with this one again, sometimes that will solve it. Other than that the only way I know of to fix it is at the stealership.

 

man i hope thats not the case they will charge me a fortune

 

how much will that cost me???

 

Hope you get everything fixed. Let us know.

 

ya i am about to try and get a wrench to take the battery off and switch it out with the tmp van its a truck we use to get around in the army its brand new so that shoudl work

 

This happened to me. I wound up having to get my second key and everything worked fine after that.

 

ok well i changed batteries that didnt do it, so i pray its just a key what all do i have to take to the gm dealership to get another key made

 

Your car didnt come with two keys?

There is a few ways that you can go about this. I took my key to the stealership and got my VATS number. From there I ordered the correct key off the internet (stealership wanted $99 for a key) and then had the key cut locally.

I understand you may not have the time for this so you may have to by the key from the dealership. In that case youll need drivers license, registration, and insurance.

 

where do i go to order online and i just take my key to the stealership and they willgive me my vats number?

 

On eBay (dont know if I can say that because they are not a sponsor) they should have the keys if you search for "pontiac vats key" or "chevy vats key" (although I believe all of them just had a GM logo). You just have to know the resistance value.

If I am breaking a rule by posting this please let me know and I will remove it right away.

 

Sometimes it's just that the key contacts or the contacts in the ignition switch are dirty (causing an increase in resistance). Try cleaning the contacts on the key with a pencil eraser and then some rubbing alcohol and spray some contact cleaner in the ignition switch. It's worth trying before spending money on a new key.

 

much better to try this first, should have thought of that earlier.

 

well the key is good, i have to change out ignition cyclinder which will cost about 200 to tow the car,150 for cyclinder and new key and they said about 500 to 600 to pull the steering wheel

 

You can put in a VATS bypass kit for a lot less than that.
