The "security" light came on for a while as I was driving, and then went out. After I got home and parked, the next time I tried to start the car, the dash lights came on, but the engine start system did not do anything, no noise, no power drain, nothing. Also, the shift would not move out of Park; brake pedal pressed or not. The car uses the chip embedded keys, and neither of the two I have worked. What is wrong, and how do I fix it?
Same experience here! There is a detailed write-up here: http://vatspasskey.com . I have a 94 Park Avenue and this was the only way I was able to save it.

the security light will flash and disable the fuel injectors preventing the car from starting, if it thinks that it is being stolen. its easy to fix. set the parking brake to turn off the automatic headlights. next turn the key to the on position and wait ten minutes. the security light should stop flashing. then turn the key off and this will reset the security system. it should start immediatly afterwards.
turn key from off to the on postiton. does the security light blink?
if so leave in on postition until light stops blinking (10min) then try to start car. may have to repeat process up to three times.
if the security re-learn process works, you will need a new ignition cylinder with security sensor. if not local gm dealer can tell you for sure.
the security system is malfunctioning .turn key to the run position for 12 minutes then finish turning the key the rest of the way to start this resets the security system.
