How to Start a Ford F-150 With a Key (Including a Dead Key Fob)
How you start a Ford F-150 with a key depends on the trim. F-150s with a traditional ignition (common on work-truck trims such as the XL) start by inserting the key in the ignition on the steering column and turning it to START with your foot on the brake. Trucks with push-button start do not have a key slot. If the fob battery is dead, you unlock the door with the hidden mechanical key blade inside the fob, then place the fob in the backup start position (on many recent F-150s it is in the center console, often at the bottom of a cup holder or a marked pocket) and press START with the brake applied. Check your owner’s manual for the exact spot on your year.
Ford has sold the F-150 with both classic keyed ignitions and Intelligent Access push-button start, sometimes in the same model year depending on trim. That is why owners of trucks like the 2023 F-150 search for where to “insert the key” or how to start the truck manually when the fob dies.
Starting an F-150 With a Traditional Key
- Sit in the driver’s seat and fasten your seat belt.
- Put the key in the ignition on the right side of the steering column.
- Press the brake pedal and make sure the shifter is in Park.
- Turn the key to START and release it once the engine runs.
If the key will not turn, gently move the steering wheel left and right while turning the key. The steering lock may be engaged.
How to Start a Push-Button F-150 With a Dead Key Fob
Slide or press the release on the fob and pull out the mechanical key blade.
Use the blade in the lock cylinder on the driver’s door handle. On some trucks the cylinder is hidden behind a small cap that you pry off gently from underneath.
Put the fob in the backup start location, usually in the center console. On many F-150s it is at the bottom of a cup holder or in a marked console pocket, with the buttons facing up as the manual shows.
With your foot on the brake, press the START/STOP button. The truck reads the fob’s chip even with a dead battery.
Replace the coin battery soon so the fob works normally again.
Find the right battery in what battery a Ford F-150 key fob uses.
