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

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.

1. Perform a security system relearn. 2. Let the vehicle sit for more than 10 minutes with the key off. 3. Attempt to start the engine, leave the key in the run position, monitoring the security system indicator. 4. After 10 minutes, the security indicator will change state. 5. Turn the key off and wait 10 seconds. 6. Attempt to start the engine. If the engine stalls, wait another 10 minutes with the key on. 7. After the second 10 minute timer has expired, turn the key off for 10 seconds. 8. Attempt to start the engine. If the engine stalls, wait another 10 minutes with the key on. 9. After the 3rd 10-minute timer has expired, shut the key off for 10 seconds. 10. The security system will relearn on the 4th starting attempt, and the engine should start and run.

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.

If the engine is shutting as soon as you let the key go to the run position, you need to recheck the wiring at the switch. There is a power supply to the ignition in the start position (more voltage to the ignition for cold starts) then when it goes to the run position, voltage is lowered.
