SOURCE: how can i reset my passlock system on my 2001

Passlock system is crazy, GM should be terminated for good just for coming up with this system and putting it on all there vehicles. to me this is by far one of the worst goofs of all time, but I think they had it planned as a money making scheme to begin with...Anyways if your security light on the dash is flashing first try unplugging your battery and wait a few minutes and hook it back up. If the light is still on it wont start. proceed to step 2, turn your key forward all the way to the farthest on position. Now go have a drink talk on the phone whatever just wait 15 mins and come back. If the security light is now off, turn the key off and wait 5 or ten seconds and your car should start.. If the light is still blinking or staying on it wont' start. step 3...try a different key if you have one and do the 15 min mess all over again. Hope you have a strong battery. If that doesn't work you probably will need to get your ignition key switch replaced. I Buy them at local part stores, Orielys and off ebay for under $100. The GM dealer wants about 500+ to do this. **** on them, do it yourself or get a friend to.

Your Passlock may need to relearn the ignition keys, if the ignition lock has gone bad like my in-laws Grand Am Gt, here is what i did so they will not get stranded any more. Buy a Passlock by pass module for around $70.00. You can order one from GMPASSLOCK.COM in the mean time try resetting the Passlock. Good luck

Ignition keys relearn takes about 30 min to do. 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.

SOURCE: how do i reset the

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

My 2003 Chevy impala will not trun over at swith


Does the "security" light come on? It may be an issue with the GM Passlock anti-theft system. There is tons of information on repairing the GM Passlock problems. Just search for "2003 Passlock issues."

Security light flashes car wont start


It's could be your PassLock security system that is failing. It started happening earlier this year on my 2002 Impala. If you wait about 20 minutes, it's starts right up after it resets. It started to happen every couple weeks and then every couple days, after a few months. I ended up bypassing the security by soldering in some resistors.

See the pictures at:
http://s2.photobucket.com/albums/y48/ZeeVert/2002%20Impala/PassLock%20Bypass%202011/
It took me about two hours to take apart the dash and carefuly double check everything I did, and take pictures. If I did it again... maybe 45-60 minutes (plus getting resistors).
I was lucky to have some resistors close to what I needed, so it cost me nothing but some time.

My ignition resistance checked at 1250 ohms. I used three resistors totaling about 1400 ohms. (At least according to my $10 meter).
Seems to work, even after I disconnected & reconnected the battery.

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.

Passlock Ignition - Chevrolet knows this is a problem, but their answer is "The Passlock Ignition is not our product, so we do not know how to fix it." Their fix??? Putting in a new ignition. Ouch! We had it done a year ago. Rumor is it will happen again eventually, and we are already dealing with a plethora of issues with our 05 Impala....Enough issues that I, a long-time Chevy owner, will not buy another chevy product. It is one thing for a bad model to come out...I can understand that...What i can not understand is GM not standing behind their shoddy product.... Poor customer service means I'm saying goodbye to Chevrolet.
