![Question](https://ls1tech.com/forums/images/icons/icon5.gif)
Hello again. Just got this 2002 z28 2 months ago. As of this morning, the security light came on. Car performs flawlessly, but the Security light stays on. I only have one key, and yes, its clean. I have looked up the vats bypass online, but all I have found were directed toward older lt1 models. Would the vats bypass work (resistors under the dash) to remedy this problem? I am a college student and money is a factor.

I have now bypassed the vats as mentioned before. However, the security light remains on. Sent it to work with a friend today who will put it on the scan tool, as I am hoping the code just needs deleted. Otherwise, I am stumped as to what it could be. Does anyone else have any suggestions or ideas as to how to fix this? I need this car running 100% a.s.a.p.

im not 100% on this but if day your key is a 15ohm you cant just put a 15ohm resistor in, you have to wire it in series or something, it was explained to me by whitebird *could be wrong on the name drop*

Got it figured out now, It was the key lock mechanism. I was just using the wrong resistor (stupid me). I found this site to be of a great help, as I was totally ignorant to the world of resistors.

Now I can continue to be ignorant to resistors, as this site does the thinking for me!

Someone accidentally hurled on my dash & steering column while i was driving,
soon after the security light came on.
http://shbox.com/1/pass_key.html
excerpt from the page:
The lock cylinder circuit is continuously monitored. If a fault lasting 1 minute is detected, the SECURITY lamp will light. If the fault then goes away for 1 minute, the lamp will go back off.
If the system detects a fault with the lock cylinder circuit after the engine is already running, the SECURITY lamp will light. The engine will be able to be restarted. This is called “fault enable mode”. (The system saw a good reading from the key at one point during a previous ignition cycle before the failure. So, it considers it a problem and not someone trying to steal the car.) When in fault enable mode, PASSKey protection is disabled until the problem is repaired. Once repaired, the SECURITY lamp will go out about 1 minute after the key is turned on. Fault enable mode will not shut down the engine while you are driving.
Cant be rolling around with my anti-theft inoperable so,
Got some q tips and some 91% rubbing alcohol and cleaned/dried out the key & key cylinder.
Problem fixed.
