CR2450 doesn't fit every key for these cars. The same model year can use a different battery with a different key type, for example:
  • 2022 Ford Bronco Sport: Passive key uses CR2450; Integrated keyhead transmitter (key with remote buttons) uses CR2032.
  • 2024 Ford Escape: Push-button-start key (Intelligent Access) uses CR2450; Remote flip key (key-start vehicles) uses CR2032.
  • 2025 Ford Explorer: Push-button-start key (Intelligent Access) uses CR2450; Police remote (Police Interceptor only) uses CR2032.
  • 2026 Ford F-150: Push-button-start key (Intelligent Access) uses CR2450; Flip key (key-start vehicles) uses CR2032; Police Responder remote (Police Responder only) uses CR2032.

What “CR2450” means

CR2430 has the same 24.5 mm diameter but is thinner (3.0 mm), and CR2032 is smaller in both dimensions. Similar-looking cells are not interchangeable: use the exact code your manual lists for your key type, or the code printed on the old battery.

Battery safety

  • Keep coin batteries away from children. A swallowed coin cell can cause severe internal burns within hours. If you think a battery has been swallowed or placed in the body, get medical help immediately.
  • If the battery compartment does not close securely, stop using the key and keep it away from children.
  • Hold the new battery by its edges and avoid touching the circuit board or contacts.
  • Replace only with the same type, and recycle the old battery according to local rules.

If the key still doesn't work

  • Check the battery orientation and that the cover is fully closed.
  • Make sure the new battery is the exact code listed above — similar sizes are not interchangeable.
  • If the buttons still do not work, contact a franchised dealer. We do not cover key programming or security systems.
