2006 chevy impala won't start

You can try to reset system by turning key and letting on run for ten minutes and then turn to off position for 1 minute. Repeat procedure a total of 3 times.

Try touching the positive and the negative battery cables together and then hooking them back on battery then this is important 1-- unlock with key (if not locked lock it then unlock all doors with key leave doors open and put key in try to start leave in the on position for ten mins until light stops blinking then try starting it again if it don't start then leave key in on position wait ten more mins and start truck as always hope this helps good luck

Usually you will need to disconnect battery, wait 5 minutes, reconnect battery, turn vehicle to on position but do not try starting. Wait 15 minutes with key on. Turn off vehicle, wait one minute. Lock door, unlock door. Try starting.

Close the doors. Lock the doors using the buttons on the key fob. Use the fob to again unlock the doors. The key should then work the ignition. If this will not work, you will have to tow your vehicle to the dealer and buy a new key and/or fob and have it programmed to the vehicle.

Hello:Try this procedure: turn key on, turn to start, let key come back to on wait ten minutes, turn key off wait 10 seconds turn key back on wait 10 minutes. turn key off wait 10 seconds turn key back on wait 10 minutes turn key off wait 10 seconds NOW try and start. In addition you might try tapping on switch assembly while trying to start. There is not any way to disable passlock. You might try having the engine control system codes read

Passlock sensor in the ignition switch is probably bad.try starting the car,when it does not start leave the key in the run position for 10 minutes,then try to restart the car.(after the car sits for ten minutes the security light should be out.) If it now starts you need a new passlock sensor.

Your keys need to be reprogramed, especially if you have disconnected the battery. To do this operation you will need 30 minutes of your valuable time or take it to the dealer & pay through the nose. Turn your key to on position but do not start. Leave key on for ten minutes & then shut off & on. Again do not start & leave key on for ten minutes. Do this a third time the same way. Turn off after the 3rd 10 mins. & start car. The key will be reprogramed to the power control module. Do this procedure with any spare keys. Good luck!

Make sure the doors and trunk,and hood are shut,open them,and shut them .activate the anti theft,wait about 1 minute,and disarm it,see if it will start,if not,the key fob may need to be relearned,try turning the key on,leave it ten minutes,then turn it off,and right back on,then wait ten minutes,and turn it off,and right back on,do this a total of three times,,30 minutes,then try and start.

Are you reffering to the alarm or the pass lock system that put the theft light on.....If its the alarm the put the key in the door and unlock it. If its the pass lock system put the key in the ignition and turn it on and try to start the vehicle. After it shuts itself off leave the key on for ten min until the theft light stops flashing the turn key off and try to start it again. This may take a few times....
