Ive read through the other similar posts but cant come to a definitive answer to my question. I have an 03 tahoe that has issues turning the key unless it's in the exact right spot. In addition to the difficulty turning the key, my radio has a tendency of turning back on after the key is removed until I put the key back in, turn to acc, and turn it off again. I figured this was a sign that I needed a new lock cylinder so I ordered a replacement which came with new keys.
After putting the new lock cylinder in, the truck will start and then immediately die, indicating likely a passkey issue. When the truck turns off though, the passkey light goes off immediately. I know all about the usual relearn sequence of key on, try to crank, wait 10 minutes until passkey lights turns off, key off wait 5 seconds, try again and on 4th try it will start and stay running. All that is good and all but my passkey light doesn't stay illuminated, it doesn't flash, it just goes off. Is there a way to "teach" the ecu to work with the new cylinder and key?
Also, after putting in the new cylinder, the radio just never turns off. Key in, out, turned, not turned, I even put the old cylinder back in and I can't get the radio to turn off now. The truck will start and stay running with the old cylinder in, but the radio issue went from an annoying process to switch it off to not turning it off no matter what I do.
I know the cylinder has a resistor of sorts in it that is likely causing my start but no run condition, but I don't know how to go about fixing it or swapping something from the old cylinder to make it work.
Anyone have any ideas for the lock cylinder issue as well as the radio issue? Thanks for your time.
