Replacing the battery in your 2018 Ford Escape key fob is a straightforward task that can save you a trip to the dealership. The key fob for your 2018 Escape utilizes a standard CR2032 3V lithium coin battery, which typically lasts between three to five years depending on usage. When the battery begins to fail, you might notice a reduction in range or the need to press the button multiple times before the door locks. This guide provides a detailed walkthrough of the process, ensuring you can complete the replacement quickly and without hassle.
Identifying a Failing Key Fob Battery
The signs of a weak key fob battery are often subtle at first but become increasingly frustrating. You might find yourself standing closer to the vehicle than usual to unlock the doors, or the remote might fail to operate entirely if the trunk is positioned behind the vehicle. Another clear indicator is the need to hold the button down for a longer duration than normal for the system to register the command. If the key fob's panic or panic button suddenly stops working, battery failure is the most common culprit, though it is always wise to rule out any potential interference issues first.
Gathering Necessary Tools and Materials
Before you begin the replacement, gathering the correct tools ensures a smooth process. You will need a fresh CR2032 battery, which is widely available at pharmacies, hardware stores, and online retailers. While a specialized key fob battery tool exists, a small flathead screwdriver or a coin can serve the same purpose for prying open the casing. It is also recommended to have a soft surface, like a towel or cloth, ready to place the key fob on during disassembly to prevent scratches.
Step-by-Step Replacement Procedure
The physical process of changing the battery involves separating the two halves of the key fob housing. Follow these steps carefully to avoid damaging the internal components.
Step 1: Locate the Hidden Screw
On the back of the 2018 Ford Escape key fob, you will find a small rectangular cover. Use your fingernail or a small tool to pop this cover off, revealing a single Phillips head screw. Remove this screw carefully and set it aside in a safe location to prevent loss.
Step 2: Separating the Key Fob Halves
With the screw removed, locate the seam running along the edge of the key fob. Insert your thumbnail into the gap near the key ring and gently twist to pry the two halves apart. If the seam is tight, you can use a flathead screwdriver, but be cautious not to apply too much pressure to the fragile circuit board inside.
Step 3: Replacing the Battery
Once the key fob is open, you will see the battery secured in place with a plastic bracket. Note the orientation of the old battery; the positive side is usually marked with a "+" symbol and should face up. Carefully lift the old battery out of its slot and insert the new CR2032 battery, ensuring the positive side is oriented correctly.
Reassembling the Key Fob
After installing the new battery, reassembling the unit requires attention to detail to ensure the device functions correctly. Align the two halves of the key fob, making sure the circuit board and battery sit flush within the housing. Avoid forcing the halves together, as this could crack the casing or bend the contacts. Once aligned, apply firm pressure to snap the seam closed.
