SOURCE: theft light blinking/car won!t start

If you have key numbers on the door, you should enter the code, then immediately start the truck. If this does not work contact the dealer for a sequence to reset the alarm.

SOURCE: when I try to start

If any of the gauges are blinking and going haywire and the security light flashing then the instument cluster is faulty.But if it is just the security light flashing then its in the switch.If you only had the switch replaced then you need a new ignition lock cylinder because its worn out.

The process for the passlock relearn is correct. If by chance the relearn does not work, you may have a fail component in the system. Go to this link for options to fix this yourself.

Y olsdmobile lss 98 is on security light flashing and won t star how to fixed


put key in ignition and turn all the way like your'e going to start it but don't start it. the security light is going to be flashing. leave it for ten minutes like that until the security light turns solid(not blinking). Turn the key to off and then start it. The tumblers in the ignition lock cylinder are no good any more and the ignition switch needs to be replaced and reprogrammed.

Security light blinks car won't start disconnected the battery used a different key still won't start


need to reprogram the security system. turn the key to start position then to run . let the key stay on until the light stops flashing. repeat these steps 3 times then the car should start if there is not a problem with the pass-lock sensor in the ignition switch or the BCM( body control module).

Car won't start security light blinks


If the security light is blinking, then the security system is DEFINATELY the reason why your car won't start. The actual cause of the problem is MOST LIKELY a defective ignition switch that is not sending the information from your key to the computer.

Try this:

FIRST try a different key if you have more than one for the vehicle. I have had cars towed into my shop simply because someone was trying to use a cheap duplicate key that was cut at the hardware store. These keys are fine for the doors and trunk. They are great to have around in case you lock your keys in your car. However, they do not have the electronics built into them to allow for engine starting.

If you are using the correct key and a second key also does not work. then...
1. set your parking brake (this will disable your daytime running lamps and conserve battery power.)
2. Connect a battery charger to the vehicle battery if you have one, or see if someone can connect to your battery with jumper cables.
3. Turn the ignition to the START position for about one second. Then release the key to the RUN position. DO NOT turn the ignition OFF.
4. Wait about 10 minutes until the security light quits flashing. Turn the key (without turning it off) to the START position again. The engine should start. If it does not, then you will have to get your car towed in for service.

HINT: you may want to try this a couple times to make sure you are doing it correctly before towing.

If it does start, it is recommended that you have your security system checked for fault codes. I have seen this many times, and it only gets worse and does it more often until this method no longer works to get it started.
