Took me less than 2 minutes. Super easy to switch everything over. Same weight and feel as the original.Just be sure when you are taking the old fob apart, not to go gorilla on it. Finesse it open; I just used a pocket knife and wiggled it.Great product, and saved me countless dollars at the dealership.

Works great. Looks good, was easy to change. No problems so far and it fit perfectly. Used on a 2016 chevy Silverado

Great fit and more sensitive than the original.

There was no way that battery from original was going to fit. I took my dremel and shaved off 1/32 of an inch of battery holder. This allowed me to place battery in snugly and fits well. The stock GM key fob has a silicone gasket and seems to be somewhat waterproof. The aftermarket fob has no gasket and would not be waterproof.Pro: It is much easier to open up the key fob than the GM originalCon: In my case I had to shave down battery holder to load battery. No silicone seal for waterproofing. No bow tie emblem on back of fob.With that being said looks great and works. It most likely will retain its good looks because it is hard plastic where as the GM fob has a soft exterior that deteriorates quickly and looks terrible.

Very easy to install and great value for the price. Looks just like oem and is very durable . Battery life is great and nice color.

Nice replacement case but it is too easy to depress the door lock button. It rises higher than the surface of the case and is too easy unintentionally press when in a pocket or purse.

Very easy to put together if you watch video. Works and looks great

None of the reviews on this product provide useful information, so hopefully this will help some people decide.This is a CASE ONLY. You must have an existing key fob to buy this, and you must open up the factory one to switch over the microchip. This WILL NOT work by itself. Since you are switching over your currently working key fob microchip, you do not need to get it programmed at the dealer.If you need a completely new key fob, there are options on Amazon that come with a completely new key fob and programming tool for around $50. Those seem to be hit or miss, but it’s still way cheaper than the dealer.There’s not a lot of good videos out there on opening up the original key fob case (the only slightly hard part), and I don’t want to give any specific advice because I essentially destroyed my old case with a flat head screwdriver trying to get out the old microchip. I will say to pry open near the bottom where the key ring goes through. If you pry near the top by the lock/unlock buttons your screw driver will definitely be scraping up against the microchip.Now for this case: The original case has a rubbery front on it. It feels better, but wears out quickly (which is why so many people are buying these aftermarket cases). This one looks the same as the original from a distance, but it’s obviously cheaper quality once you feel it. I will say, the side chrome pieces are actually made out of metal instead of plastic, which was a nice surprise. The front of this case is a hard plastic, not rubber like the original. Who knows how long the front will last, I don’t think this key fob design has been around long enough for people to be able to test out the durability of it. However, for $10 a case, you really can’t go wrong. It’ll last long enough.I really don’t care that the front is plastic on this case. However, here is why I only give 3 stars. The case is just a millimeter or two, too small for the microchip. You can feel that the case doesn’t quite close all the way around the microchip, and when you snap everything together, it’s a tight fit. It doesn’t feel tight enough to damage the microchip, but just slightly too tight (as in front to back/ thickness of the case).Because of the tight fit, the buttons are extremely sensitive. You WILL get accidental button pushes in your pocket. Just note that that lock button seems to be the easiest to press. I don’t care if my vehicle locks again; however, if the unlock button were any easier to push, I would send it back. I would say these buttons are about 3X more sensitive than in the original factory case. Simply lightly placing your finger on the lock button will actuate the button. On my first trip to the store with the new key fob case, my truck locked on me again when putting the keys into my pocket. Since the horn honks when locking, I can see this becoming annoying over time. Like I said, since it’s the lock button and not the unlock button that is the most sensitive, it’s not as much as a safety issue. I wouldn’t want to chance accidentally unlocking my vehicle when putting the keys into my pocket.All that being said, I will still keep the key fob case. The dealer will charge $100 for a new key fob, and another $50 to program it. I went to the dealer, and this is what they tried to charge me. I’ll stick to $10 on Amazon for a new case, even with the poorer quality and performance. The extra cost simply isn’t worth a new one from the dealer.One more thing to note, I looked at pretty much all the cases available on Amazon for this key fob. Every one seemed to have something negative about it. Either too big, too small, or even poorer quality materials. This one seems to be overall OK on everything, and a solid 3/5 star product.
