Tried to program a spare pontiac grand prix key, and the security light would not stop after ten minutes.

nitabelle57, It sounds like your security system will not recognize the new key you purchased. Keys have a chip in them which has to be recognized by the security system in order to work. The new key has to be programmed by your security system before it will start your vehicle. You will need a battery charger to program the key as this procedure takes thirty minutes to do. Put the charger on the battery. Be sure everything else is turned off. Place the new key in the ignition and turn it to the run position. The security light should come on. After ten minutes the security light should be out, if not proceed anyway. Turn the key to the off position but do not remove it. Wait five seconds and turn it to the run position once again. Wait another ten minutes and turn it off again. Wait five seconds and turn it to the run position once again. After the final ten minutes turn the key off (do not remove it) Wait thirty seconds and then the key should be programmed. If you have any other keys they will not work now as the security system is now programmed for the one key. If you have another key and need it for another driver then start the vehicle with the newly programmed key and let it run for about a minute. Place the extra key in the ignition and turn it to the run position and wait sixty seconds. This should solve that problem. Good luck with this.

its sensing the key your using will not pass the security. try using the spare key if you have one. you may need to have the ignition switch and key replaced and programed to the vehicle. hope this helps

• disconect battery for 30 seconds, reconect.
• try to start car, leaving key on for 10 minutes or untill security light stops blinking.
• Turn key off

then try to start car. if this doesnt work repeat procedure.
Hope this helps

Turn the key on and wait for the security light to stop blinking (may take about ten minutes). Then turn the key off and wait for at least one minute. Then try to start. That should program the key chip.

Use the key to unlock the door on passenger side.

hold the reset button on the fuse panel and when it blinks let off of it and it will go away

there is a computer chip in the lock cylinder that goes bad ,so change the key and cylinder,then leave new key on until the light stops flashing about ten minutes this will set your new key to the security system hope this helps

Try this. Roll down the drivers side window. Close the door and turn the key to the On position. Don't try to crank the car right now. Leave the key on for ten minutes. After ten minutes turn the key off then try to start the car. This procedure tells the computer that it is not being stolen and it will reset the security system. This should hopefully let your car start. I hope this is helpful.

There is no way to disconnect the security system on your car but there is a way to reset it. Roll down the drivers side window and close the door. (Stay out of the car, this is why you roll down the window) Reach in and turn the key to the On position. Don't try to start it. Leave the key on for ten minutes. After ten minutes, reach in and turn the key off. Then try to start the car. This usually will reset the security system. I hope this is helpful.
