Security Light - But Blazer starts, and runs, light just on
So I get in my blazer to go to walmart, and as I am driving I notice the security light is stuck on. Last time this happened the blazer wouldnt start because of the passlock. Well I drove to walmart, maybe 5 minutes, and parked, came out maybe another 25 minutes. Started the blazer right up, but the light stayed on.....
I have no idea what this could be, but as of now, the blazer is still starting just like it used to... Any ideas?
I searched the forum and google, and haven't found where the blazer started with it on.... KYLE?!!?

Just means the ignition switch is starting to fail...hasnt yet...but it will.
The light will start randomly coming on while youre driving...then youll start having the flashing security light and no start condition.

My 1998 had a faulty passlock system, where every 300 starts would result in it locking up my fuel system for 15 minutes. I bought the 1998 at 110k, and sold it at 161k. In those 5 years, I dealt with the issue, but never did anything to correct it, because besides from those mornings where I was late to work because of the passlock, it didn't cause any real problem. 
((TAKE ALL THE CRAP OFF OF YOUR KEYCHAIN!!!)) My mechanic told me that failure in the passlock systems is caused directly by extra weight on the keychain, which causes the key to go into the ignition crooked. Your car thinks its being stolen...and BAM! Another issue with the older, higher mileage Blazers is the rear hatch separating from the glass. This little bit of play in the catch of the hatch will alert the system to possible foul play, and not illuminate the DOOR AJAR. My 2002 blinks security whenever a door is ajar (vehicle off). Also, take your key inside, and scrub it clean...that may help! GOOD LUCK!!!

I had my starter remote, house key, work key(s), and a key to my safe. Not that much weight, but he advised me to separate my keys. Well, by that point, the damage was already done...so...?

I only have my key and the remote to my alarm and I have passlock issues. Don't know how to solve this so I just wait the 10 minutes before I can start the truck. Just sucks but nothing I can do. As for the security light, mine just recently starting coming on while I'm driving. It happens once in awhile.
