Yes! After installed, trun key on (engine not running) for 30 mins.,trun off and back on for 10mins., turn off and back on for 10 mins. more; flashing light will go off turn off and try starting engine. Good luck! it's GM's reset for that.

What years of 1999 Chevy Cavalier are compatible with ignition cylinder. Looking for any compatible years or models??


1995 to 2001 Cavalier & Pontiac Sunfire ignition lock cylinders are the same. Be advised that your car has an anti theft system. If you plan on installing a used cylinder from another car, you will need to have the replacement cylinder "coded" to your original key OR have a key with the same resistor value as your original key, cut for the replacement cylinder [new or used] Without doing this, the car will not start.

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.

2005 Chevy Impala ignition switch stuck in off position


Someone may have tried to steal the car and damaged the lock's internal pins. Replace the entire lock with new.

Key wont start car


Do you have the old one. The new one must be cut wrong. Or you have a bad lock cylinder.

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.
