2015–2020 Ford F-150 Key Fob Battery Type and Replacement

Which Ford F-150 model years does this cover?

These key fob battery specifications apply to every Ford F-150 built from 2015 through 2020 — the 13th generation (2015–2020, aluminum body), full-size pickup (aluminum body, steel frame). Nothing in this specification changes between those model years. Pick your year for the engines it offered, what changed that year, and the problems recorded against it.

What battery does the 2015–2020 Ford F-150 key fob take?

A single CR2032 (flip key); two CR2025 (2015–17 intelligent-access fob); CR2450 (2018+ smart fob), open the fob and match the old cell coin cell.

Can you use a CR2032 instead of a CR2025 in a 2015–2020 Ford F-150 key fob?

Usually. Both are 20 mm across; the 2032 is 3.2 mm thick against the 2025's 2.5 mm, so it holds more charge but is a tighter fit and can strain the contacts in a shallow housing. If the case will not close cleanly, use the specified CR2032 (flip key); two CR2025 (2015–17 intelligent-access fob); CR2450 (2018+ smart fob), open the fob and match the old cell.

How do you open a 2015–2020 Ford F-150 key fob?

Slide out the mechanical emergency key first, which usually releases a catch, then part the halves with a plastic pry tool or a coin wrapped in tape. A screwdriver will mark the case and can crack the seam.
