Resolving Key Fob Not Working Issue in a 2022 Ford Explorer

Repair Instructions:

Step 1: Check and Replace Key Fob Battery

Use the small flat-head screwdriver to carefully pry open the key fob case.
Remove the old battery and note the orientation (+/-).
Insert the new CR2032 battery, ensuring it is positioned correctly.
Snap the key fob case back together.
Test the key fob functionality by attempting to lock/unlock the doors.

Step 2: Inspect Key Fob Condition

Examine the key fob for any visible signs of damage.
If damaged, consider replacing the key fob entirely.

Step 3: Reprogram Key Fob

Access the Vehicle: Sit in the driver's seat with the key fob.
Turn on Ignition: Insert the working key fob into the ignition and turn it to the "On" position without starting the engine.
Press the Unlock Button: On the key fob you wish to program, press the "Unlock" button for 5 seconds.
Turn Off Ignition: Turn the key back to the "Off" position.
Test the Key Fob: Attempt to unlock or lock the doors with the newly programmed fob.

Step 4: Check Vehicle Battery and Fuses

Test Vehicle Battery: Use the multimeter to check the voltage (should be around 12.6 volts).
Inspect Fuses: Check the fuse box for any blown fuses related to the keyless entry system.
- Replace any blown fuses with the correct amperage rated fuse.

Step 5: Perform a Key Fob Reset

Enter the Vehicle: Ensure all doors are closed and sit inside the vehicle.
Cycle the Ignition: Turn the ignition on and off six times within 10 seconds (On - Off - On - Off - On - Off - On).
Door Locks: You should hear the door locks cycle, indicating the reset was successful.
Test the Key Fob: After resetting, test the key fob to see if functionality is restored.

Conclusion

If none of the above steps resolve the issue, consider consulting with a Ford dealership or a certified locksmith, as the key fob may require advanced diagnostics or replacement programming. Additionally, if the vehicle has an issue with the keyless entry system itself, professional assistance may be necessary.
