My 2000 Camaro occasionally will not start. I will turn the key and nothing
happens other than the security light will come on (steady, not flashing)
for 3 minutes, and then go out. If I then turn the key to the off position,
it may or may not start on the next attempt.
I only have one key, but it works flawlessly 50% or more of the time. I
have read a lot about the passlock system, but everything refers to a
flashing security light.
You may need a new key, or a new sensor for the passlock system.
I have had a ton of problems on my older Reatta with this system, but I
think this was a different vintage of the passlock system.
In my case, I finally bypassed the reader with a resistance equal to the
resistance in the key insert. That worked for a while but finally stopped
working...maybe the resistor fried...who knows. The Reatta is so
undependable that I have just lost faith in it ever being drivable.
Passlock sensor in the ignition lock is bad.
Passlock sensor is part of the lock housing, can be changed and old ignition
cylinder may be reused.
Not something that will show on a scan.
New sensor will have to go through a lean procedure.
