Beefunny Honda Accord & Insight Replacement Key Fob 2018–2021 — 5-Button, 4A Chip, FCC CWTWB1G0090

This Beefunny replacement remote key fob is a complete aftermarket key for select Honda Accord and Insight models (2018–2021) with FCC ID CWTWB1G0090, equipped with a 5-button layout, 4A chip and 433.92MHz FSK frequency.

Before buying, verify the FCC ID, part number, button arrangement and chip type match your current remote.

What functions and buttons are included on this 5-button key?

Who is this for: This Beefunny replacement is intended for Honda owners (Accord 2018–2021 and Insight 2019–2021) who need a full aftermarket remote with built-in chip and emergency key. It suits drivers who prefer a cost-effective non-OEM alternative but understand that proper cutting and programming by a pro are required.
