SOURCE: electronic chip in key

As far as bypassing the securtiy chip, we can't tell you that one as it would assist any user on here to steal your car (or others).
When you turn the key to attempt to start it do the dash lights dim or even go out ?

99 blazer security light stays on


The security light means the computer is not reading the chip in the key.
You should have a sensor in the key lock and a chip on the key programmed for the security system.
I would try a spare key first. If you don't have one, you can get one from the dealer or some locksmiths.
If you know you have a good key, the problem may be with the sensor in the lock cylinder.

My security light is on and my car wont start.


Try disconnecting the NEGATIVE battery terminal wire for about 5 minutes, that probably will do it.


Your passlock security is activated. Many things can cause this. 1 or more of three things. The key chip is bad, the ignition cylinder that reads the key is bad, or the TDM (Theft Deterrent Module-computer that reads the info) is bad.

Won't start security light comes on and flashes for about 20-30 mins till solid then will restart. recently started having no lights come on for up to 1 hr or more and have left overnight.


Try a different key
Usually the security light and no start mean the system can't read the little black chip imbedded in the base of the key

Flashing security light


if ur key has the security chip in it, it possible that ur ignition switch isnt reading that chip right away. i mean as long as u can get ur car started try and not get too worried about it. it is possible that ur ignition might be goin bad so try to keep an eye on it and if it starts to get worse take it in.

Car doesn't start randomly. "security" light comes on and off. Have to leave key in "on" position for 10 min. to reprogram. Is there a fix?


you may have the same problem I ran into and have to turn your key on don't start the car yet wait about ten seconds with key on on position then turn it over should stop the security lite from coming on all the time and locking the fuel lines. let me know if this worked
A mechanic told me maybe if I replace the ignition that may be it setting off the security sensors? I don;t know I just wait ten seconds with the key on before I start it and as long as I do that it seems to work every time.
