I've been reading all over the itnerenet and searching this forum for months and want to know if anybody has a direct solution for the security light/ no start issue? I have found like 5 different solutions, I think that getting a new key an cylinder is my choice, but seriously I've been searching. Anybody got a direct fix? (fyi I don't want to bypass) Thank you.

The fix is to replace the bad component in the system. It's usually the ignition cylinder, but it can also be the BCM...

My security light used to be on almost all the time (I was fortunate enough to avoid the no start issue) until I replaced the ignition cylinder for another reason. Since then, I haven't seen the light again...

you may or may not need a new key cut. It depends on how wore down your current one is. If you get a new cylinder and take it to a locksmith, they can key it to your current key, but they may need to cut you a new one. Either way, a locksmith will be able to key it so your ignition and door keys are one and the same.

You do NOT need to buy a GM key.

If you can take apart the dash and pull the ignition switch, you will be able to replace the lock cylinder yourself. It's not hard. Should take you about 45mins - 1hr tops. If you can do the work yourself, just order a lock cylinder from ZSPOT. Should be around $130. When you receive it, take it to your local locksmith and have them key it. I'm guessing they will charge $15-$30 to set it up, depending. Then swap it and perform the security relearn procedure.

Or you can take it to the dealer and you will probably be looking at around $500 by the time it's all said and done Sad

When I replaced my lock cylinder for the same problem you had, but mine got worse. The key was so worn that it wouldn't even recognize it anymore. You put it in, but it wouldn't turn. Purchased new lock cylinder, came with new keys already keyed for this new lock cylinder. We got whatever they had in stock as we were unable to drive the car when this happened. I believe it was around $150, but the guy knew of a discount code and applied it to the order and got us around $20-$30 off, which was VERY nice!

Now I just have to have one of the old keys and one of the new keys on my keychain. Not really a big deal. It's a fairly simple process as I did it and I'm only 16.

No. That would imply everyone here would overlook all it's glaring flaws and all of the better competition while talking about how much they like it.

you can try your spare key and see if it works, but you likely have a problem with the sensor in the lock cylinder itself since that is where the passlock sensor resides ... contrary to what the GM dealer may tell you to get you to buy keys with the GM logo on them for 3 or 4 times the price you can get them at a locksmith shop or hardware store...

I am unsure if they changed it for the 06+ models or not. I'm sure that topic has been discussed, I just don't remember.

I had my bcm replaced. so far no security light (its been 2 days) so might not be the cylinder.
