1996 buick regal, put key in ignition,car wont start

usually the security light comes on when the Chip on the key is not being read. this triggers the security light. With mine I had to replace the ignition switch to get it to read the key. If its just the light no problem, BUT if your car starts to develop a crank without starting this means its time to change that faulty ignition switch

Is your SECURITY light flashing? If so, you have a V.A.T.S. problem. VATS stands for Vehicle Anti Theft System. Try getting a new ignition key made because the resistance value has probably changed in the one you have. If that doesn't do it you'll need to get a VATS bypass.

could possibly be anti-theft problem with key or vats system.
is your security light flashing. if you have questions , call or text me

call an expert - electrician- to check whether your immobilizer has been activated and wont get off.

WELL DID YOU REPLACE BATTERY IF YOU DID OR IF BATTERY WENT LOW IT MAY HAVE SET SECURITY SYSTEM ANY WAY IF YOU HAVE SECOND KEY TRY IT FIRST IF NOT PUT KEY IN RUN POSISION FOR FIFTEEN MIN OR SO SEE IF LIGHT GOSE OUT THEN TRY TO START CAR IF YOU HAVE TOW KEY TRY THIS WITH BOTH IT COULD BE THE CHIP IN KEY WENT BAD BUT IF THIS DOSE NOT WORK THE WIRE SOME TIME BRAKES AT STEERING COLUM SO YOU HAVE TO FIX VERY COMEN HOPE THIS HELPS DO NOT LET BATTERY DIE WHEN YOU DO THIS SO IF YOU HAVE BATTERY CHARGER PUT ON WHILE YOU TRY THIS OR MAKE SHERE BATTERY IS CHARGED

Yes, I can tell you how to bypass it, but it is easier to just replace the ignition lock cylinder. That is what is bad.

yes it could check batteries in the remote or check the security wires on the back of the ignition switch behind the steering wheel
