Replacement Shell for 4-Button GM Fobs

This new key fob shell replaces the outer case on Chevrolet Silverado 1500 and GMC Sierra models from 2014 to 2023, plus Colorado and Canyon trucks from 2015 to 2022. It is intended for owners whose original remote housing is cracked, worn or cosmetically damaged but whose internal electronics still function. No transponder chip, circuit board or battery is included, so the buyer must move those parts from the old remote. The shell matches the four-button layout shown in the product images.

Fitment Decided by FCC ID and Part Numbers

Compatibility hinges on matching the FCC ID M3N-32337100 and the listed OEM part numbers such as 13577770, 84540865 and 13580082. If the original remote carries a different FCC ID or part number, this shell will not fit even if the vehicle year and model appear in the application list. Buyers must verify those identifiers on their existing fob before ordering.

No Electronics Means No Reprogramming Required

Because the shell contains no circuit board, transponder chip or battery, installation is a simple case swap that does not trigger a relearn procedure. The mixed metal and plastic construction restores the tactile feel of the original four-button remote. This product does not serve buyers who need a complete replacement remote with fresh electronics or a new transponder chip.

Questions about this item

What does the four-button layout mean once the shell is on my key fob?

The shell replicates the original four-button arrangement — lock, unlock, tailgate and panic — so every function lines up with the circuit board you move over.

Which FCC ID does this case match and what does that confirm?

FCC ID M3N-32337100 confirms the shell matches the factory remote used on 2014-2023 Silverado and Sierra models.

What physical parts must move from my old fob into this shell?

You transfer the circuit board, transponder chip (ID 46) and battery; the shell supplies only the buttons, key blade slot and housing.
