SOURCE: 2005 Chevy Impala wont start

The most common cause of this problem on the Impalas is their @$!@ security system called Passlock or Passlock II. It is very sensitive and senses an intrusion a lot of times even when there is not one. When it does it locks down the fuel injectors. You can leave the key in the ignition in the on position and wait 10 minutes for it to re-set but it tends to do this 4-5 times a month at a minimum. The way to permanently solve this is to disable this portion of the system.
You will need to take the dash off ( it is not as hard as it seems) It is held in place with a variety of bolts, screws, and clips. You can do a web search for dash removal to try and find the exact configuration. Once the dash is out under the steering column there is a metal plate. It needs to come out also (held in place by a few bolts. Once this is removed you will have clear access to the underneath part of the steering column. Coming up the steering column you will see (3) wires grouped together. (Yellow, Black, and White). They will either be tied or taped together. The only one you need to concern yourself with is the yellow one. This is the most important step. (1) Start the car! (2) While the car is started snip the yellow wire, making sure it does not contact any metal. (3) using electrical tape or something similar cap off the ends and tie it off if you wish. (4) Turn off the car, put the plate back on, the dash back together and problem solved!. The yellow or orange security light will stay permanently illuminated, but it is not a problem. I did this on my Impala which I inherited 10 months ago and have never had this problem again. You can take the bulb out of the instrument cluster to for the security light but it is a lot of trouble and not worth the effort. Hope this helps..

• A module which communicates on the class 2 serial data circuit which supplies VIN information to the radio is replaced and not properly setup with the correct VIN information for that vehicle. The only way to unlock the radio is by using a scan tool.

SOURCE: how do i reset the security system on my 2003

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....

SOURCE: 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.

I got a new ignition and my 2005 chevy impaula will not start what do i do


The security system is locking you out after the ignition change. You will need to have it "learned" or bypassed.

My 2005 chevy impala won't start since someone broke into my car


i would say when the person broke into your car they set off the security system which stops the car from starting, the way to reset the security is to put your key into the ignition turn the key until all the dash lights come on and let them stay on about 15 minutes after the 15 minutes have expired turn the key off and wait about 3 seconds and then your car should start. hope this helps.

Reset the security system after installing a swicth 2001chevy Impala


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.
