Hey X1X GOSER X1X,

If you are replacing the electrical part of the ignition switch you may have to relearn the PASSLOCK system.

You may need to attach a battery charger as you will have the ignition on for a while without the engine running whilst doing the relearn.

Please see the information below on how to do that.

Regards, Joe

I've recently lost the keys to my car and was wondering how I would replace the lock cylinder without having to drill it out?

There is no way except to drill it out. Here are guides to help you replace the ignition lock tumbler. Can you please shoot a quick video with your phone so we can see what's going on? That would be great. You can upload it here with your response. I would get the new ignition switch from the dealer so they can code it for you please bring our VIN number. Check out the diagrams (below). Please let us know what happens.

Hello,

I have a question regarding this install. I just replaced my ignition switch on my fathers 2005 Impala due to the popular pass-lock issue and the vehicle not starting.

I purchased the ignition kit from GM, where a service tech told me I do not need to have the car re-keyed or programmed if I keep the stock tumbler and install it in the non-defective pass-lock. I have installed the ignition, everything is hooked up, and everything in the car works, but it wont start. I am wondering if this is due to the new pass-lock? I am not sure how it works with different keys and so-forth. I was also told it could also be the BCM but to try this first. So my question is, could the car not be starting due to the new pass-lock not recognizing the car, and being a programming issue, or has the problem spread to the BCM and I need to replace that too?

Thank you

I think the tech was not complete even if you keep the tumbler the key is what needs programming which the dealer will do when you buy the lock and key if you bring your VIN number and proof of ownership.

I have a 2000 Impala and have been having trouble with the Passlock security system. I have just removed the ignition switch and disassembled it to clean the contacts which were blackened. When I got it back together and put the key in I get the door chimes but no other lights on the dash or any other action. Any ideas? I know it probably needs to go through the reprogram sequence but right now the ignition switch is not working. I should see dash lights when I insert the key even if it does not start?

So you took apart the ignition switch and cleaned it and now you don't have any power to the dash lights blower motor etc?Have you checked all the fuses to see if you blew any? Here are the instructions on how to replace the ignition switch in the diagrams below.

Lets start by checking the solid red wire to the ignition switch it should have battery voltage to it at all times. So all the dash lights blower motor etc worked before you took the switch apart?Let me know if you have battery voltage to that solid red wire. You just have a bad ignition switch since you took it apart parts aren't made to be repaired these days we live in a throw away world.

Yes I do have battery volts. I did not remove the lock cylinder, all I did was remove the cover from the actual switch and clean the contacts. That is why I was asking if it could be another problem. Should I get dash lights and radio no matter what else is going on if I insert the key and turn it?

Yes you should have the dash lights warning lights blower motor working etc. So did the starter work when you turned the key to the start position before you cleaned the switch?Also put the key in the start position and see if you have battery voltage at the yellow wire coming out of the ignition switch. Let me know.

Looks like the ignition switch isn't working correctly and needs to be replaced to start with. As you can see from the diagram I posted the red wire feeds the battery voltage into the switch and when you turn the switch to the start position battery voltage is sent thru the yellow wire which isn't happening. But the red wire has battery voltage so bad switch you could have more then one problem but getting a new switch is where we need to start.

Thanks for your help. I was assuming it was the switch but I wanted to get another opinion in case I was missing something. I will get one in the morning and try it.

I installed the new switch and now I am back to my original problem of not being able to start the car because of the passlock security system. I have tried the reprogram sequence of turning the key to run and letting it sit for 10 minutes. I also did it 3 times in a row like some people say but it still will not start. Do you think it could be a bad passlock sensor? Is there any way to test this?

When you did the relearn procedure and did it three cycles did you make sure you waited for the security light to change status like the light was flashing and shut off or went from flashing to solid or solid to off before you did the next cycle of turning it off then trying to start it and let it sit in the position until the light changed status again before the next cycle was performed?I would also try it four cycles to see if it resets. You could have a bad pass lock sensor iam having trouble logging into are online repair data as soon as I can I will get you more info.
