SOURCE: 95 Impala SS. My Pass Key Fault light is on but

Try this, it may help. If not your going to have to take it to the dealer and have them hook up the tech2 scanner.
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.

2000 chevy impala won't start but everything comes on

you have a shorted battery (have it tested) or there is a loose connection. A starter motor pulls a large amount of current when it engages, a loose conection or shorted battery will all the voltage away from the dash,lights etc.

Does the security light in the dash blink?
Thinking it's a pass code fault(ignition switch)
There is no chip in the key,the computer looks for the proper rotation of the switch,had the same thing happen,
Should be able to start it if you crank the engine for a few seconds,release the starter and DON"T turn the key off,wait 10 minutes,crank it again,should start.
If not do the procedure again(had to do it 3 times on mine)
This is the relearn procedure that also has to be run after the switch is replaced(with a new key also)

How do i reset the security system on my 2003 chevy impala

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....

1995 chevy impala ingnition

I had the same problem last summer. Poor thing was dead for 2 months. Finally figured it out. Under the steering column (under the driver's side dashboard) there's a small connector with an orange cable that has two small white wires inside it. These wires come from the ignition switch, and run to the PCM (computer). The small chip in your key isn't being detected. The two wires on this connector connect to the key when it's in the slot. The ignition switch is bad, and not connecting to the key when it's inserted. Try cleaning up the chip contacts on your key, or try your spare key if you have one. Also spray a small amount of contact cleaner into the ignition switch. Insert, and re-insert the key a bunch of times to clean up the inner contacts. This should take care of it. Post a follow-up message to let me know if it worked or not. There's another solution, but it's not something I'd wanna post online because it gives away how to bypass the Pass Key theft deterrent system.

1994 chevy impala will not start battery is charged

if the pass key light is flashing you may have to take it to a shop and have it diagnosed. i had this problem with my 98 sonoma. my problem was that the pass key sensor was bad. for some reason the car is not recognising your ignition key and is going into security mode. this one is almost impossible for the do it yourselfer unless you have a scan tool. (not a code scanner) this is how gm gets you.

Does a light come on that looks like a lock?? This is GMs Passlock problem. It a fault in the ignition cylinder. The car won`t turn over. If you remove the key, the car will start in 8 to 10 minutes. Some have found that spraying an electronic spray or silicone based spray in the ignition and rapidly turning the key back and forth may help. Repeat this several times. Replacing the ignition switch is an expensive option, but may have to be done.
