Gotta have 4 doors..... Rawhide, TOTY 2023!
I had this same issue with my '99 Burb, and in my experience the "relearn procedures" lasted a few times at best. What finally worked was to get it electronically deleted from the PCM.Thanks for the reply. I don't know if the battery went bad due to a parasitic draw, if so if it was the PassLock that did it, or if it was just a bad battery.
What I do know is that I was having PassLock issues: starts, runs a few seconds, SECURITY light staying on. I could usually get it to work by disconnecting the battery. Sometimes (perhaps every time?), when I reconnected the battery, I would have to leave the key on for 10-12 minutes until the SECURITY light went out. Usually, I had to leave the battery disconnected for more than a few minutes, but i never could determine the minimum amount of time (determining that is not an easy test.) Connecting a jumper across the battery connections (battery removed, of course), hoping to more rapidly drain any "memory", didn't seem to speed up the process. Finally, the battery went way down overnight when NOTHING was connected to it. That was certainly not normal. I had the battery tested and got it replaced under warranty.
When I connected the new battery, I went through the full 30 minute "relearn" procedure. I don't know if a single 10-12 minute key on would have done it or not. Once I decided on the full 30 minute relearn, I stuck with it. Everything seems fine now, but I still don't trust it. My gut tells me that the chance of the PassLock preventing a theft is less than the chance of it causing trouble down the road. It is likely not a high target truck, and my lifestyle now is such that I don't often put the truck in theft vulnerable situations. I'm willing to take the chance and spend $120 for piece of mind. Thus, my original question.
In 2019 that cost me $250 at a shop that does a LOT of tuning and such on LS platform vehicles and engines. It's in far west Houston, actually Rosenberg.
