Is your 2018 Ford F-250 key fob not working? The most likely culprit is a dead battery. Fortunately, replacing the battery in your key fob is a straightforward task you can easily handle yourself, saving you time and money. This guide will walk you through each step to get your key fob working again.
Finding the Correct Battery for Your 2018 F-250 Key Fob
Ford F-250 key fobs typically use either a CR2032 or CR2450 battery. To ensure you purchase the right one, it’s always best to check your owner’s manual or the battery itself once you open the key fob. These batteries are widely available online and at most stores that sell batteries, and they generally cost less than $6.
Step-by-Step Guide to Replacing Your 2018 F-250 Key Fob Battery
Replacing your key fob battery is a simple process that should only take a few minutes. Here’s how to do it:
Opening Your Key Fob
The method for opening your Ford F-250 key fob can vary slightly depending on the model year.
For newer 2018 Ford F-250 key fobs:
- Locate the hidden key: First, you’ll need to remove the mechanical key from the key fob. There is usually a small release button or latch that you can press to slide the key out.
- Insert the key into the designated slot: Once the key is removed, look for a slot or notch where the key was housed. Insert the end of the mechanical key into this slot.
- Gently twist or pry: Carefully twist the key or use it to gently pry the key fob case open. The case should split open along the seam.
For older 2018 Ford F-250 key fobs (although less common for this year), or if the above method doesn’t work:
- Find the notch: Examine the edges of your key fob for a small notch or indentation.
- Use a thin, flat object: Insert a thin, flat object like a flathead screwdriver or a plastic pry tool into the notch.
- Pry open the case: Gently twist or pry to separate the two halves of the key fob case. Be careful not to apply too much force to avoid damaging the case.
Replacing the Battery
Once the key fob case is open:
- Access the battery: Carefully open the case and locate the circuit board and battery. Gently lift the circuit board if necessary to get to the battery.
- Note the battery orientation: Before removing the old battery, take a moment to observe how it is positioned in the case. Note which side is facing up (+) and down (-). This will ensure you insert the new battery correctly.
- Remove the old battery: Gently pry out the old battery. You may be able to use your fingernail or a small tool to help with this.
- Insert the new battery: Place the new CR2032 or CR2450 battery into the battery compartment, making sure to match the correct orientation you noted earlier (+ side up in most cases).
- Close the key fob case: Carefully snap the two halves of the key fob case back together until they are securely closed.
Testing Your Key Fob
After replacing the battery and closing the case:
- Test the buttons: Press each button on your key fob to check if it is working correctly. Try locking and unlocking your doors, and testing any other functions your key fob has, like remote start or panic button.
- Troubleshooting: If your key fob still doesn’t work, double-check the battery orientation and ensure the battery contacts are clean and making good contact with the battery. You can gently clean the contacts with a cotton swab and a bit of rubbing alcohol if needed.
Understanding Key Fob Types
Key fobs come in various designs, but the battery replacement process is generally similar across types. Here are five common types of key fobs you might encounter:
- Standard Remotes: Basic remotes with standard lock, unlock, and sometimes panic buttons.
- Flip Keys: Remotes with a mechanical key that folds out, like a switchblade.
- Remote Heads: Remotes with a permanently attached, non-retractable mechanical key blade.
- Fobik Keys: Remotes with a hidden mechanical key inside, where the key and fob are separate pieces when the key is removed.
- Smart Keys: Remotes often associated with push-to-start ignition systems, offering features like proximity unlocking.
When a New Battery Isn’t the Solution
If you’ve replaced the battery and your 2018 Ford F-250 key fob still isn’t functioning, there might be a more significant issue. In this case, you may need to consider replacing the entire key fob. You can explore replacement options online or consult with a professional locksmith or your Ford dealership for further assistance.
Replacing your 2018 Ford F-250 key fob battery is usually a quick and easy fix for a non-working remote. By following these steps, you can likely restore your key fob’s functionality and avoid unnecessary dealership costs.
