Chevy Colorado: 2015-2018 Chevy Impala: 2014-2017 Chevy Impala Limited: 2014-2016 GMC Canyon: 2015-2018 ADDITIONAL INFO Do you need to change the locks in your vehicle? Maybe you've had a key stolen and you want to play it safe. Maybe you've got a domestic situation that requires re-keying your vehicle. Maybe your cylinders are simply defective or worn out. Regardless of the reason, you've found the right listing! These are fully assembled non-coded OEM original GM cylinders that include two key blades, already cut to match!! Don't settle for someone else's cylinders that require assembly. That is tedious and usually best left to professionals. Get the cylinders already assembled, ready to go in the vehicle. And why go with an aftermarket reproductions when you can get a factory original? These items are from a complete lock and cylinder kit that was ready to go in a GM vehicle on the assembly line. (These are overstock leftovers.) An example of such kit can be seen in the last picture. Please note, keyfobs are NOT included in this listing, as indicated in that picture. ABOUT US: We are NOT a salvage yard. We are NOT affiliated with a salvage yard. We don't have the typical auto parts mentality. We specialize in one thing: factory audio/video. We are very picky and strive to provide radios that we would be proud to have in our own vehicles. When you buy a radio from us, you are getting a unit that is guaranteed to work. Occasionally problems arise with used radios as a result of mishandling during shipping. However, please know that we never knowingly send out a radio that exhibited problems in our testing. It is not in our best interest to send out defective units because we waste time and money replacing them under our warranty. This is why our radios are tested before they are even inventoried. We aim to keep our returns low and our customer satisfaction high. Please give us a chance to add you to our long list of satisfied customers. SHIPPING HANDLING Shipping cost is based on weight and zip code. This site does the figuring, not us. If you feel their calculation is high, you might be underestimating the package weight and/or current shipping costs from our zip code (62401) to yours. Please don't ding us for shipping in the ratings, as we have no control over ever-increasing carrier rates. We will enter a tracking number into your order details here on the site. They will email it to you if your notification preferences are set correctly. A signature is not typically required. If you are not home to receive the package, it will most likely be left at your door. Please monitor it's progress and arrange to collect it when it arrives. This site provides a section/tab in each ad for Shipping information. We encourage you to check that section for prices, methods, time-frames, etc.
