The ignition on 30-year-old truck started acting wonky a month ago. Truck started fine, but key would not fully return to 'run' position after starting engine, which resulted in being unable to move the column shifter out of 'park', unless I pushed the key cylinder in, the then manually turned the key back slightly. This happened more and more frequently, until one day (thank God it happened at my house), the key got stuck in the 'run' position, and I had to pull the fuel pump fuse, and then disconnect the battery, to shut the truck off. Thankfully, I had already ordered this part, and bought the two special tools needed to do the job (steering wheel puller, and steering wheel lock plate compressor). The part has no instructions, but there are plenty of YouTube videos. Not too hard of a job on my pre-airbag truck. It was the best $30 bucks I ever spent. The key works smoothly, in all positions, and no more having to jiggle/play with the lock cylinder. It also goes into 'accessory' position, which the old cylinder did not. In all fairness, though, the original cylinder lasted 30 years, so that's pretty good. Do yourself a favor, and go with this OEM part, rather than an aftermarket key cylinder. Do yourself an even bigger favor, and don't wait too long to do this job, if you notice your ignition is acting wonky, or else you may find yourself stranded.

I replaced Ignition Key in my Chevy Astro Cargo Van. This was a perfect fit. Quality seems good. It turns smooth and pretty much plug and play swap. It comes with two keys and no instructions of any kind. Very easy to install once you get to the point where you can locate the locking screw which holds the lock cylinder in place. Overall I am very happy with this product. Recommended to every one.
