2020 Ford Explorer Smart Key Fob Battery Replacement Steps
Accessing the Key Fob Battery
Open the smart key fob by firmly pressing the release clip on the side and sliding the two halves apart. Carefully lift the internal board to expose the CR2032 coin cell, noting how the positive side faces up for reassembly.
Tools and Safety Precautions
Use a plastic pry tool and a small crosshead screwdriver. Avoid metal tools near the circuit board to prevent shorts. Work on a clean, non-conductive surface and keep the old battery away from children and pets.
Installing the New Battery and Testing
Place the new CR2032 with the correct polarity, close the fob halves until they click, and verify that the panic and unlock buttons respond immediately. If the fob does not work, recheck orientation and seating before proceeding to programming steps.
2020 Ford Explorer Remote Key Battery Options
If your vehicle uses a traditional remote with a mechanical key, the battery is a standard 3V CR2032 or CR2025 accessible from the back cover. Always match the part number to the original to ensure correct voltage and housing fit.
Some models may require seat and door proximity module resets after replacing remotes, especially when all remotes are replaced at once. Using genuine or high-quality aftermarket parts reduces the risk of intermittent signal issues.
2020 Ford Explorer Key Fob Programming Procedures
Programming with One Working Remote
With one working remote, insert any metal key into the ignition, turn to ON, press the lock and unlock buttons simultaneously on the working remote, then press the button on the new remote. The security light should blink to confirm programming success.
Programming with No Working Remotes
When no remotes work, use the seat and center console controls to cycle through the security reset process. Refer to the vehicle instruction card or dealer app for step-by-step guidance, as incorrect sequences can extend downtime.
Common Issues and Signs of a Weak Key Fob Battery
Slow dashboard response, inconsistent remote range, and the security warning light are typical indicators of a low 2020 Ford Explorer key fob battery. Ignoring these signs can leave you stranded when the last battery dies at an inconvenient time.
Replacing the battery early preserves the internal buttons and contacts, preventing costly repairs. Keeping spare key fobs programmed and fresh ensures you always have reliable access to your Explorer.
