Key Fob Shell Case Replacement for Chevy Silverado Colorado GMC Sierra 1500 2500 3500 HD Canyon 2014 2015 2016 2017 2018 2019 2020 2021 M3N-32337100 4 Button Keyless Entry Remote Car Key Fob Cover

I recently purchased this key fob shell replacement for my Chevy Silverado, and it fits perfectly. The 4-button design matches my original key fob exactly, and installation was super easy — I was able to transfer the internal electronics without any issues. The material feels durable and high-quality, and it seems like it will hold up well against daily use. I also appreciate the snug fit — the buttons are responsive, and there’s no wobbling or rattling when I press them. This shell is a great, cost-effective solution for anyone whose original key fob is worn, cracked, or faded. It works for multiple Chevy and GMC models, which makes it a versatile option if you own more than one vehicle. Overall, a highly recommended purchase.

Excellent replacement. Husband took the workings from original and easily inserted. Great quality and works perfectly. Cannot tell the difference in this and original.

Very nice replacement shell. Everything fit perfectly into it. Seems to be pretty durable as I’ve had it for quite awhile now. No issues at all!

Why did you pick this product vs others?: I chose this product because of good price point, mostly decent reviews, and it virtually mimics my original 2017 GMC Canyon fob. In fact, when I put it together as indicated in my attached photos, I was able to snap on the old GMC logo battery cover to the new fob shell. Ease of replacement: The hardest part was removing the old broken shell from the circuit board. I had to use a screwdriver to pry it apart. Once that was accomplished there was no issues with inserting the circuit board into the shell and snapping the new fob shell pieces together with the side chrome pieces. I then easily installed my battery, and I noticed the new non-logo battery cover is the same dimensions as my original GMC logo cover so I snapped it on to complete the fob. Ease of use: Unlike several naysayer reviews, I have found the lock, unlock and start buttons work flawlessly for the past 10 days I have been using it. ​ Durability: ​I realize only time will tell how long this new fob shell will hold up and work, but it seems to mimic the OEM fob very well at this time.

My old key fob broke where it attaches to the key ring. I ordered this. It came in quick. It was super easy to take the computer chip out of the other one and place it in this one. It worked immediately, and it looks nicer than my other fob

Seems to be a good quality item. Exact fit.

We initially considered spending $150 plus additional reprogramming costs for a new key-fob. Instead, we decided to invest $10 to evaluate the alternative. The original fob is challenging to disassemble, and there is a risk of damaging it during the process. The replacement fob presents well, with only minor differences from the OEM version, primarily the logo on the reverse side. With careful handling, it may be possible to reuse the old fob if preferred. Overall, the replacement appears to be of good quality, and all functions operate as expected. Some reviews mention issues regarding incomplete closure of the shell or improper placement of the board during assembly, though we did not encounter these problems.

Works like a champ. Easy to swap and works great. Range has even improved. Looks very professional too.
