2019 Ford Focus Key Fob Programming

On this Ford, the remote functions are built into the smart proximity key — there's no separate remote to program. Use the key programming steps to set up the proximity key, which handles remote lock, unlock, and start.

If your Ford has push-button start, you can add a new smart key yourself when you already have two working smart keys. You'll have 30 seconds to complete the sequence, so read it through first. Up to 4 smart keys total.

1. 1Place the new smart key, buttons facing out, in the center-console pocket.
2. 2Press the driver or passenger power-unlock button three times.
3. 3Press and release the brake pedal once.
4. 4Press the power-lock button three times.
5. 5Press and release the brake pedal once. The Start/Stop button starts flashing — programming mode is active and the two working keys were detected.
6. 6Within one minute, press the Start/Stop button. The message center confirms the new key was programmed. (If you see MAX # OF KEYS LEARNED, four keys are already programmed and you can't add more.)
7. 7Take the new key out of the pocket and press Lock or Unlock on it to exit programming mode.
8. 8Test that the new key locks, unlocks, and starts the vehicle.

Your 2019 Ford Focus key fob uses a CR2032 3V lithium coin cell. A fresh one typically lasts 3–5 years.

How to replace the battery

1. 1 Look for a small notch or screw on the side of the fob where the key blade meets the buttons.
2. 2 Pry the housing apart with a coin or small flathead (or remove the screw).
3. 3 Pop out the old coin cell, noting its orientation.
4. 4 Insert the new battery the same way up, then snap the case shut.
5. 5 Test the buttons — if they work, you're done.
