Review on ACDelco 15841209 Original Equipment Ignition: Superior Performance and Reliability by Dave Brummet

Pros: The price was right ($36.25). Prime Class makes delivery convenient. The research helped me prepare for the coding aspect; Coding is automotive jargon and means "A key code is a string of alphanumeric characters used by locksmiths to create a key." I had to watch videos on YOUTUBE to learn how to program. This product was unreliable. On my car, a very important part of the cylinder lock ignition switch broke off (after I installed it). I've only had the item 2 weeks. If it wasn't for that, the price was great. I have attached 2 photos to show the problem. Unfortunately, that money was thrown to the wind for me. Do yourself a favor and go to your local auto parts store. You can choose one of these similar (compatible) items for a little more money, but the product is guaranteed.
