Many fobs have a hidden release slot near the key ring or emergency-key blade. - Note the battery orientation (usually positive side up) before removing the old cell. - Avoid touching the new battery's faces with bare fingers; skin oils can shorten its life. - If the fob doesn't work after replacement, check that the battery is seated fully and the contacts weren't bent. Most vehicles do not need re-pairing after a battery change. ## Which Ford F-150 model years does this cover?

A single CR2450 (intelligent-access smart fob); base remote-head keys use CR2032, open the fob and match the old cell coin cell. ### Can you use a CR2032 instead of a CR2025 in a 2021-2025 Ford F-150 key fob? This fob takes a CR2450 (intelligent-access smart fob); base remote-head keys use CR2032, open the fob and match the old cell, so start there.

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.
