How to Replace the Key Fob Battery in a Lincoln MKT

1. Slide the release on the back of the transmitter and pull out the mechanical backup key blade.
2. Twist a thin coin under the tab hidden behind the backup key head to pop off the battery cover.
3. Take out the old battery.
4. Insert the new battery with the + facing downward and press it down so it sits fully in the housing.
5. Snap the battery cover back onto the transmitter.
6. Reinstall the backup key.

• Battery type: one coin-type three-volt lithium CR2032 or equivalent.
• Do not use the backup key to remove the cover, as it could damage the intelligent access key.
• Do not wipe grease off the battery terminals or the back of the circuit board; replacing the battery does not delete the transmitter from the vehicle.
