You can measure the ohms of resistance in the key chip in the middle of the key then buy 1 or more resistors from radio shack and bypass the key reader if your mecanically inclined i think i can walk you through it via live support

When you locked your car did you use the fob to lock the car? If so close the car door and unlock the car using the fob!! If you use the remote/fob to lock the car you must use it to unlock the car otherwise the car will not start and will stay in Security mode. I have a 99 as well and found that little trick out lol.

99 Pontiac bonneville wont start. just get a humming. no crank or starter sound


This may be related to the antitheft security system. The system is known for turning off the starter and/or injectors when it fails. When it's the security locked out starter, you won't even hear a click when you turn the key. Is there a light on the dash that says SECURITY or a picture of a car with a lock through it? This is a common problem worth looking into. http://www.diy-gm-security.com/
