Great deal on oem parts. It was hard to find a set that didn't require two separate keys and at this low cost. People were using worn keys to gain access to my truck due to the old worn locks that I had. With these I no longer have to worry about that. I installed this set on a 2000 GMC Sierra SLT2. Install was fairly easy but I had to watch a bunch of different videos to figure it out as each video had slight differences in the trucks they were demonstrating on. I think I could have figured it out without the videos but it would have taken me much longer (at least with the ignition lock). It's easy but a bit time consuming removing things just to get to the locks. The ignition lock gave me a bit of trouble putting in because every video I watched left out a simple step. I do not recall what it was I had to do but I remember I had found the solution in one of the comments in one of the videos. I have never done locks on a vehicle before but I do pretty consistently work on locks at my job. Word of advice, constantly check your work long before closing your door or putting everything back together. If you find out you did something wrong after everything is back together and closed, you could be in a mess of trouble. Pay attention and check your work.
