LAMP #25 RED SOLiD glows =

During normal operation, after turning on the ignition
switch, the Vehicle Security Alarm Indicator Light will
turn on for three (3) seconds for a bulb check. If the light
remains on after the bulb check, it indicates that there is
a problem with the electronics. In addition, if the light
begins to flash after the bulb check, it indicates that
someone used an invalid key to start the engine. Either of
these conditions will result in the engine being shut off
after two (2) seconds.
If the Vehicle Security Alarm Indicator Light turns on
during normal vehicle operation (vehicle running for
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 15
longer than 10 seconds), it indicates that there is a fault in
the electronics. Should this occur, have the vehicle ser-e
viced as soon as possible (comment scan it)

Your best bet would be to have a qualified repair shop hook up diagnostic tool to check DTC'S - diagnostic trouble codes an diagnose the problem . Sounds like you may not have knowledge on this an you could make the problem worse .

You can't do anything ,unless you have diagnostic computer . Check codes , program key etc.... Call a mobile lock smith or have towed to the dealer .

flashing because theirs a problem and your security is activated --can be problem with key- ignition switch-immobilizer -short -computer etc --check and inspect key first

For some odd reason Chevy sometimes has there stereos connected to the security system. Check the fuse to make sure it didn't blow. You probably have vats security which is the worst thing ever made. I had that on my 02 firebird and had nothing but vats issues constantly.

check to see if security system is working (activeated) ,look at fuses

Hi, Seems that the SKIM (Security Key Immobilizer Module). Try locking and unlocking drivers door, sounds like security system was triggered. If unlocking and locking door does nothing locate (ECU) fuse, (Main) fuse, and (IOD) fuse. If so pull fuses turn key to on position do not start, wait 3 to 5 minutes install fuses and try starting. Please also check battery connections for clean and secure.

scan Body control module for security codes . Car still starts right? Possible reflash needed

ITS OK MAN
