Your 2017 Ford Explorer key fob is a critical piece of technology, granting you access and control over your vehicle.

Don’t let a weak key fob leave you stranded or fumbling for your keys in a dark parking lot. This guide will walk you through the straightforward process of replacing the battery in your 2017 Ford Explorer key fob, ensuring you regain full functionality quickly and easily.
Why Your 2017 Ford Explorer Key Fob Battery Matters
The battery inside your 2017 Ford Explorer key fob is a small but mighty power source. It powers the transmitter that sends signals to your vehicle, allowing you to lock, unlock, and even start your engine remotely. Over time, like any battery, it loses its charge. You might notice a weaker signal range, or the buttons might become unresponsive.
Ignoring a dying battery can lead to frustration. Imagine juggling groceries, kids, or camping gear and having your key fob fail to unlock the doors. Replacing the battery is a simple preventative maintenance task that saves you hassle and ensures your Explorer is always accessible. It’s a small fix with a big impact on your daily convenience.
Identifying the Right Battery for Your 2017 Ford Explorer Key Fob
Before you begin, you need the correct replacement battery. For the 2017 Ford Explorer key fob, the standard battery is a CR2032 3-volt lithium coin cell. This is a very common battery size, readily available at most supermarkets, drugstores, electronics stores, and online retailers.
When purchasing, look for reputable brands. While generic options might seem cheaper, established brands often offer better longevity and reliability. The CR2032 is a 3-volt battery, so ensure you don’t accidentally purchase a different voltage, as this could damage the fob. The “20” refers to the diameter in millimeters (20mm), and the “32” refers to the thickness in tenths of a millimeter (3.2mm).
Tools You’ll Need for the Job
The beauty of replacing your 2017 Ford Explorer key battery is that you don’t need specialized tools. Most owners will have everything they need right at home.
- A small, flat-head screwdriver or a plastic pry tool: This is essential for gently separating the two halves of the key fob. A plastic trim tool is ideal as it’s less likely to scratch or damage the fob’s casing.
- Your new CR2032 battery: Make sure it’s fresh and from a reliable brand.
- A soft cloth: To wipe down the inside of the fob if needed and to handle the new battery without leaving fingerprints.
Avoid using sharp metal objects like knives or excessive force, as these can easily damage the delicate plastic clips that hold the fob together. Patience and gentle prying are key.
Step-by-Step: Replacing Your 2017 Ford Explorer Key Battery
This process is designed to be straightforward. Follow these steps carefully, and you’ll have your key fob working again in no time.
Step 1: Locate the Seam and Separation Point
Examine your 2017 Ford Explorer key fob. You’ll notice a seam running around its perimeter where the two halves of the casing meet. On most Ford fobs of this era, there’s a small notch or a slightly recessed area, often near where the key ring attaches or on one of the sides. This is your primary leverage point.
Step 2: Gently Pry the Fob Apart
Insert the tip of your small flat-head screwdriver or plastic pry tool into the seam at the designated separation point. Apply gentle, steady pressure to twist the tool. You should hear a faint click as the internal clips begin to release.
Work your way around the seam with the tool, carefully prying the two halves of the fob apart. Go slowly and avoid forcing it. The goal is to release the clips without breaking them.
Step 3: Expose the Old Battery
Once the fob is open, you’ll see the internal circuit board and the coin cell battery. The battery is usually held in place by a small metal clip or sits snugly in a recess. Note the orientation of the old battery (which side is up) before you remove it. This is crucial for installing the new one correctly.
Step 4: Remove the Old Battery
Using your fingernail or the tip of your pry tool, carefully lift the old CR2032 battery out of its holder. Be mindful of the small metal contacts surrounding the battery.
Step 5: Insert the New CR2032 Battery
Take your new CR2032 battery. Make sure the positive (+) side is facing upwards (this is typically indicated by the text and a plus symbol on the battery itself). Place the new battery into the holder, ensuring it sits flush and is properly seated under any retaining clips.
Step 6: Reassemble the Key Fob
Align the two halves of the key fob casing. Gently press them together, starting from one end and working your way around. You should feel and hear the clips snap back into place, securing the fob. Ensure there are no gaps around the seam.
Step 7: Test Your Key Fob
Once reassembled, test all the buttons on your 2017 Ford Explorer key fob. Lock and unlock your vehicle to confirm it’s working correctly. You should notice a stronger, more responsive signal. If it doesn’t work, double-check that the battery is inserted correctly (positive side up) and that all internal connections are seated properly.
Common Issues and Troubleshooting
While replacing the 2017 Ford Explorer key battery is usually straightforward, you might encounter a few minor hiccups.
Buttons Aren’t Responding After Replacement
- Battery Orientation: The most common reason is the battery being installed backward. Ensure the positive (+) side is facing up.
- Battery Contact: Check that the metal contacts inside the fob are clean and making good contact with the battery. You can gently clean them with a pencil eraser or a soft cloth.
- Damaged Clips: If you used too much force when opening the fob, you might have broken a small plastic clip. This could prevent the fob from closing properly or maintaining internal connections.
- Faulty New Battery: Although rare, the new battery itself could be dead or defective. Try a different brand or from a different store.
Fob Range is Still Weak
If the battery replacement doesn’t significantly improve the range, the issue might be elsewhere.
- Internal Damage: The fob might have suffered internal damage from a drop or water exposure.
- Vehicle Receiver Issue: Less commonly, there could be a problem with the receiver in your 2017 Ford Explorer.
- Interference: Strong radio frequency interference in your immediate area can also affect fob range.
If you’ve tried a new battery and confirmed proper installation, and the range is still poor, it might be time to consult your owner’s manual or a dealership for further diagnosis.
Extending the Life of Your Key Fob Battery
While you can’t prevent a battery from eventually dying, a few practices can help maximize its lifespan and keep your 2017 Ford Explorer key battery performing well.
- Avoid Accidental Button Presses: Don’t keep your fob loose in a pocket or purse where other items can press the buttons repeatedly. This drains the battery unnecessarily. Consider a small fob holder or a dedicated pocket.
- Protect from Moisture and Extreme Temperatures: Water damage and prolonged exposure to extreme heat or cold can degrade battery performance and damage the fob’s electronics.
- Keep it Clean: Dust and debris can interfere with button contacts. Periodically clean the fob with a dry, soft cloth.
- Use the Spare Fob: If you have a spare key fob, use it periodically. This ensures its battery doesn’t sit dormant and lose its charge, and it also exercises the internal components.
When to Seek Professional Help
For most owners, replacing the 2017 Ford Explorer key battery is a simple DIY task. However, there are situations where it’s best to seek assistance.
- Damaged Fob: If your key fob has been dropped, cracked, or exposed to significant moisture, the internal components might be damaged. Attempting a battery change on a broken fob could worsen the issue.
- Inability to Open: If you cannot get the fob to open without excessive force, it’s better to stop and consult a professional to avoid breaking it.
- Persistent Issues: If you’ve replaced the battery correctly and the fob still doesn’t work, there might be a more complex electrical issue with the fob or your vehicle.
In these cases, a dealership or a reputable automotive locksmith can diagnose the problem, repair or replace the fob, and reprogram it to your 2017 Ford Explorer.
