My 2001 Buick century custom got struck by lightning and the security light comes on every time we try to crank it. We can get it to crank and run for about five seconds and it shuts off every time. What's wrong with it?

You can try this but you may have damaged components from the lightning.

PASSLOCK 10 MINUTE RELEARN

AUTO LEARN
Time required, approximately 10 minutes:

1. Insure that the battery is fully charged.
2. Use the scan tool in order to clear the DTCs.
3. Turn the ignition switch from the OFF position to the CRANK position attempting to start the vehicle. The vehicle will start and then stall.
4. Leave the ignition switch in the ON position while observing the security indicator.
5. When the security indicator turns off, which can take up to 10 minutes, turn the ignition switch off. Wait 10 seconds.
6. The BCM and the PCM will learn the new code on the next start attempt.
