Most Ford F-150 key fobs use a CR2032 coin battery, but some model years and fob styles use a CR2025 instead. The easiest way to confirm is to open the fob and check the battery number printed on the old one. Replace it with the same type, snap the fob back together, and your remote should work right away with no programming needed in most cases.

Most Ford F150 key fobs use a small coin battery. The common type is the CR2032 battery. This battery is round and flat. It is about 3.2 cm wide and 0.3 cm thick.
The CR2032 is popular because it lasts long and fits well. Many other car key fobs use this battery too.
