Replaced key tumbler on my ‘97, now won’t run

[df2x4]

That's what is great about this forum there's always someone with a great insight.

Or at least someone who's sleep deprived and thinking weird thoughts... Doesn't help that I've had trucks on the brain all day today worrying about dumping money into my Suburban's AC.

I'm still not 100% convinced that this is Aholter90's problem, but I thought it was at least worth mentioning.

Sometimes that's when I do my best thinking, lol.

Well, that took long enough lol. I got a new tumbler for a ‘98 and the truck runs again. Thanks for the help!

That's good news!

Glad it worked, thanks for updating us!

Ok, thanks for the info guys. It is a late ‘97, so it does appear to be PASSLOCKED. After messing it with it for a half hour, I do see that the security light flashes for a few seconds, then shuts off. The security light does not stay on for any portion of the 10 minute relearn. I have so far done the procedure 3 times to no avail.

Out of curiosity.. what is the 10th digit in your VIN? V, or W?

If yours is indeed a '97 (10th digit V) it would be the first '97 I've heard of with Passlock. Not saying it's impossible or untrue, just saying it's a first for me.

And yes, as you have found, with a Passlock-equipped truck you absolutely need the tumbler meant for one, which most regard as '98-up. It has the resistor in it that the Passlock system uses to determine that the truck was started with the key. Think of the old VATS system where you used to see the "chip" (resistor) in the key on the old Corvettes/Camaros etc., in Passlock they moved it to the tumbler.

In addition to the 10th digit of the VIN, I'd be curious to see the actual production date. If this is a '97, I bet it's a super late one. Unfortunately that question might require a $5 CompNine lookup to answer.

Yep, I asked on the VIN because that is the true definition of year model. Some states get weird with titles and if there was ever a title issue with it in the past.. who knows. I'll say it's definitely possible a 1997 got Passlock, anything is possible, and the facts that he's got a functional "security" light in the cluster and a 1998 tumbler got his truck starting and running again, pretty much say it all.

Manufacture date should also be on the driver door edge sticker (the tire info placard), at least down to the month/year, not the actual day of that month that you'd see on the build sheet.

I believe a GM dealer could put the last 8 digits of the VIN in the parts catalog and get the day/month/year build date. I know we could when I worked in a Chevrolet parts dept.
