Did you change the key? if you have it more than likely needs programmed as most of the gm's have either a resister based immobilizer or a passlock system. If its the same key check that you have all the connecters back at steering column as you may have disturbed the vat's one.

What is passlock security code for a 2003 chevrolet impala


Hello, if you have the security light coming on and a no start condition, this is a passlock problem. but there is no code you can use to turn off the light and start the vehicle. there is a problem with the security system, that will require checking out and repairing. in most cases this is a bad sensor in the ignition lock cylinder which requires replacing of the lock cylinder. in some cases, this also can be caused by a bad body control module

How do i reset the passlock system for the chevy impala 2001....i want to turn the damn security system off!!!!


Turn the key on, don't try to start it, let it set on for ten minutes turn it off. do this three times, after the third time your will start. Make sure you have everything else turned off. and if your lights are automatic with the key on, you will have to put a charger on the battery as you do it. because 30 minutes with the lights on will drain your battery. Also you can not disable the security system

2001 chevy impala security light keeps coming on


This is a problem with chevy vehicles that have the system theft light. after a couple of years of using the key, the lock tumblers inside the ignition switch tend to wear out and so causing the system to think it's being stolen. Now you have to put the key in and turn the ignition to the on position, without cranking the car and leave it for 10 minutes until the theft light goes out. Very annoying especially if you're in a hurry. The dealer cost to repair the ignition switch goes for about $600-$800. that includes re-teaching the key.

2001 Impala TPMS reset, radio and headlight options DONT WORK


CHEVY IMPALA &
MONTE CARLO

On a Chevy Impala or Monte Carlo with indirect TPMS, a totally different reset procedure is required. You can use the light switch or radio to reset the system. With the light switch procedure, turn the ignition on (engine off), the turn the light switch from OFF to parking lamps three times within five seconds. With the radio technique, turn the ignition on (engine off). With the radio off, hold the DISP button until “SETTINGS” is displayed. Use the SEEK button to scroll down the menu until you see “TIRE MON.” Press the PREV or NEXT buttons until “RESET” is displayed. Then press the DISP button again. You should hear a chime and see “DONE” to indicate the TPMS system has been successfully reset. Use the SEEK button to scroll through the menu until “DONE” is shown, then press DISP once more to exit from the learn mode.

How do you change a key switch in a 2001 chevy impala, the factory keys wont turn in the switch


If your key is worn try getting a new one cut.
The ignition lock cylinder and keys do not contain any coded electronic components. The lock cylinder housing contains the coded electronic components. Changing an ignition lock cylinder or replacing a key is a purely mechanical process which does not affect the vehicle theft deterrent system. To replace an existing key, simply cut a new key to match the existing one. If no keys are available, the lock cylinder must be changed. To change the lock cylinder, simply replace the existing lock cylinder with one of the same type.
If you are unable to operate the ignition cylinder with a new key then you will probably need to replace the cylinder and switch.Replacement of the switch involves reprogramming
The system may be programmed with or without a scan tool.
There is a way to get the cylinder out without replacing the switch but this procedure should be performed by a qualified GM technician as it involves removal of the switch and some precise drilling.

Change ignition cylinder? (lock?)


the new cylinder's key has a different code, so the anti-theft module has to reset to accept that code, with the old cylinder u could program extra keys as long as u had one key that worked, but since that is not the case with a new lock cylinder I think u are stuck with taking it to the dealer, any GM dealer can do this job, call around and try to get a lower estimate. Before having it towed try this work around I found on a car thread on this issue:

1) Put the key in the ignition and turn to the "ON" position. Leave it that way for 10 minutes. After 10 minutes turn the key and take it out. Repeat this process (2) more times (3 times, 30 minutes total) This should reset the passlock system to recognize your key. Not sure this will work but it is worth a try.

2001 Chevy Impala Security System


I have a 2001 Impala. My security light will flash and sometimes the car won't start. My dad told me turn the key to the start position, place your foot on the break, put your car in the last gear it was in (D, R, or N). Then shift all the way back into park. Make sure you shift all the way into park. Take your foot off the break. Then turn ignition back to off. Your car should then start right up. He said the sensor still thinks the car is in D, R, or N although it's in park. So it confuses the system and it doesn't start because it doesn't know which function to do. It pretty much locks up. I'm pos. this will work. My car does it every few months. Hope this helps.
