SOURCE: 1999 Buick regal Security light on. Won't start.

A remote starter could be the problem. Have you recently gotten a new ignition key? If you have gotten a new key does it have a chip on it? If so is it the right chip? If no chip on key then that is for sure the problem. As long as that light is on after turning ignition to the on position (not start position) the car will not start when turned to the start position. If this doesn't help you out then submit more information and i'll try to help again.

SOURCE: security light stays on

First place to check would be a fuse.  See if there is one labled security or alarm.  If there is try changing that.

SOURCE: Rear brakes need ajustment on Buick Lesabre

I don't know if this works on a Buick but I have had two cars that the auto adjusters worked when you used the parking brake, I rarely use the parking brake so I got in the habit of working the parking brake 20 times or so at oil change time.

30-Minute Learn Procedure 1. Turn ON the ignition, with the engine OFF. 2. Attempt to start the engine, then release the key to ON; the vehicle will not start. 3. Observe the SECURITY tell tale light. After approximately 10 minutes, the light will turn OFF. 4. Turn OFF the ignition switch, and wait 5 seconds. 5. Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. 3x10 = 30 minutes. The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch turn from OFF to CRANK Important: Turn the Ignition Switch OFF. The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. 6. Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password. 7. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles. Without a scan tool you may have momentary starter interruptions while history clears itself. Good luck and hope this helps, keep me posted, be glad to help.

Need key code via vin number

Your dealer should be able to do this, however if you have a security system VAT, you will need the system checked so you can get the correct key blank. The chip on the key creates a certain amount of Ohms of resistance, that matches your security system. If you use the wrong one the car will not start. There are methods to by pass, however you need your old key, even if its broken to do.

Where is the fuse located in 1998 buick lesabre to bypass security light/system

If you mean the anti-theft PASS system, it does not work that way.
You have to have power to the module, and it has to get the right signal from the key chip to start the engine.
Otherwise a car thief could start the car.

I have GMC 1999 suburban wont start and it has the security light on

If it is a Pass III system like my 1999 Buick LeSabre. It means the key is weak. When my car was four years old this happened with all my keys at once. I found in the manual it stated if chip fell out system would reset immediately instead of 2 or 3 minutes. I bought a key from Sears identically cut to my GM but blank no chip to reset the system. When I tried it the car started and I bought four more keys and have used them since. ( 8 yrs) They cost $1.29 each, and have never left me waiting in a cold car again.
