your truck ? I have a 2000 Silverado Z71 and I only have one key, I have bought blanks from ebay, Walmart and other stores, had them cut by Walmart, even took and had them cut with to old manual type key machine. I can not get a blank to work very smoothly at all and not consistent at all. I hate to be down to one key. I figure the reason the blanks are not working very well is because the original is worn and thus not a good cut when copying. Was thinking of just replacing the cylinder in the steering column if it wasnt to intense and to very much skill LOL. I have remote unlock/lock so not real worried about the doors


thanks
