Need new key fobs for your Chevy? This 2-pack from KEYXPRESS has you covered! These remotes are compatible with 2017-2020 Chevy Trax and Bolt, 2018-2021 Equinox, 2018-2020 Sonic, and 2016-2019 Volt models. They match FCC ID HYQ4AA, operate at 315MHz, and contain ID46 chips - but IMPORTANT: you must verify compatibility by checking your original key's shape, button layout, and FCC ID, not just your car model. These are aftermarket replacements (not OEM), manufactured in China, and they'll need to be programmed to your vehicle (usually by a locksmith or dealership). The pack includes two remotes, which is great if you want a spare or need replacements for multiple drivers. Part numbers covered include 13529664, 13508767, and 13585722. Don't pay dealership prices for key fobs - these quality alternatives work just as well once programmed. Just make sure they match your existing remote exactly!
