What You’ll Need
Before you start, make sure you have the following items:

- A small screwdriver or coin
- A key fob opener or a flathead screwdriver
- A cloth or paper towel to protect your work surface
Step 1: Prepare Your Key Fob
Start by preparing your key fob for the battery replacement process. Make sure your key fob is turned off and all doors are closed. If your key fob has a sliding cover, slide it open to access the battery compartment.
For Ford keys with a push-button start, you’ll need to locate the small notch on the side of the key fob. This notch is used to release the battery compartment. Use a small screwdriver or coin to press the notch and release the compartment.

Once the battery compartment is open, you’ll see the old battery. Gently pull the battery out of the compartment, taking care not to touch any of the internal components.
If the battery is stuck, you can use a small flathead screwdriver to carefully pry it out. Be careful not to damage the battery compartment or any surrounding components.
Step 3: Install the New Battery
Take the new battery and insert it into the compartment, making sure it’s aligned properly with the contacts. Gently push the battery into place until it clicks or snaps into position.
Make sure the new battery is securely in place and the compartment is closed properly. If your key fob has a sliding cover, slide it shut to protect the battery compartment.
Step 4: Test Your Key Fob
Now that the new battery is installed, test your key fob to make sure it’s working properly. Try locking and unlocking your car doors, as well as starting the engine (if your key fob has a push-button start).
If your key fob is not working properly, check to make sure the battery is installed correctly and the compartment is closed properly. If you’re still having issues, you may need to replace the key fob or have it reprogrammed by a Ford dealership or locksmith.
Tips and Precautions
Here are some additional tips and precautions to keep in mind when changing your car key battery:
- Make sure to handle the battery carefully to avoid touching any of the internal components.
- Avoid mixing old and new batteries, as this can cause damage to your key fob or car’s electrical system.

Identifying the Right Battery Type
Before you begin swapping out your Ford key fob battery, it’s crucial to ensure you have the correct replacement. Ford vehicles utilize various battery types depending on the model year and key fob design. Improper battery selection can lead to malfunctioning key fobs and even damage to the electronics.
Checking Your Owner’s Manual
Your Ford owner’s manual is your best resource for identifying the specific battery type needed for your key fob. The manual will often include a diagram illustrating the key fob’s internal components and specifying the correct battery model number.
Online Resources and Retailers
If you don’t have your owner’s manual handy, numerous online resources can help you determine the correct battery. Websites specializing in car parts or key fob accessories often provide guides and compatibility charts based on vehicle year, make, and model. Reputable online retailers like Amazon also allow you to search for batteries by vehicle make and model, making it easy to find the right fit.
Battery Size and Shape
Pay close attention to the size and shape of the battery. Key fob batteries typically come in small, round or rectangular shapes. Incorrect battery dimensions can prevent proper installation and function.
Accessing the Battery Compartment
Once you have the correct battery, you’ll need to access the battery compartment within your Ford key fob. The process varies slightly depending on the key fob design, but here are some common methods:
Key Fob with a Removable Back Panel
Many Ford key fobs feature a removable back panel that secures with a small screw or a snap-fit mechanism.
- Locate the small screw or tab on the back of the key fob.
- Use a small screwdriver or your fingernails to carefully pry open the back panel.
Key Fob with a Hidden Release Mechanism
Some key fobs have a hidden release mechanism, often located near the top or bottom edge.
- Insert a thin, flat object, such as a credit card or a small screwdriver, into the designated slot.
- Gently pry open the key fob, following the direction indicated by the release mechanism.
Key Fob with an Integrated Battery
A smaller number of Ford key fobs have an integrated battery that cannot be replaced by the user. If this is the case, you will need to contact a dealership or locksmith for assistance.
Signs Your Ford Car Key Battery Needs Replacing
Knowing when to replace your car key battery can save you from the frustration of a dead key. Here are some telltale signs that your battery is nearing its end:
Key Fob Not Responding
This is the most obvious sign. If you press the buttons on your key fob and nothing happens, or the buttons require excessive pressure, it’s a clear indication that the battery needs replacing.
Dim or Flickering Lights
Some Ford key fobs have LED lights that illuminate when the buttons are pressed. If these lights are dim or flicker, the battery is losing its power.
Keyless Entry Problems
If you’re experiencing difficulties locking or unlocking your doors using the keyless entry system, a weak battery could be the culprit.
Starting Issues
In some cases, a dying battery can even affect the vehicle’s ability to start. If you notice difficulty starting your Ford, check the key fob battery first.

Remove the Old Battery
Once the cover is removed, you’ll see the old battery. Gently lift it out of its compartment.
