Open the Remote and Locate the Battery

Most Ford keyless remotes split into two halves held together by a small screw or a slot you can pry open with a flat tool. Look along the seam where the two plastic pieces meet — you will usually find either a Phillips-head screw on the back or a thin slot on the side. If there is a screw, use a small Phillips screwdriver to remove it. If there is a slot, slide a flathead screwdriver, coin, or plastic pry tool gently into the gap and twist to separate the halves.

Once the remote is open, you will see a small round or rectangular battery sitting in a plastic holder. The battery is typically a CR2032, CR2025, or CR2016 — all are coin-cell batteries about the size of a dime. Write down the battery type printed on the surface before you remove it, or take a photo. The battery holder usually has a small metal tab or clip that holds the battery in place.

Key Takeaways

  • Ford keyless remotes open either by removing a small Phillips screw or by prying apart a slot with a flat tool.
  • The battery is a coin-cell type (usually CR2032, CR2025, or CR2016) that costs between $3 and $8 at any pharmacy, hardware store, or supermarket.
  • When you remove the old battery, note which side faces up — the positive side (marked with a + symbol) must face the same direction when you install the new one.
  • After inserting the new battery, test the remote before closing it to confirm all buttons work.
  • Reassemble the remote by aligning the two halves and either replacing the screw or pressing the slot closed until you hear a click.

Remove the Old Battery and Note Its Orientation

Gently lift or slide the old battery out of its holder. Look at the top of the battery — you will see a + symbol on the positive side and a blank or − symbol on the negative side. The positive side should be facing up (toward the buttons of the remote). Take a mental note or snap a quick photo so you remember the orientation when you install the new battery.

If the battery is stuck, do not force it. A small plastic tab or metal clip may be holding it in place. Gently lift that tab away from the battery edge and try again. Once the battery is out, set it aside — you do not need to keep it.

Buy and Install the Replacement Battery

Take the battery type (CR2032, CR2025, or CR2016) to any pharmacy, supermarket, or hardware store. These batteries are stocked in the watch and battery section and cost between $3 and $8 for a single cell. You can also order them online, but buying one in person means you can test your remote when ready.

Slide the new battery into the holder with the positive side (+) facing up, matching the orientation of the old battery. The battery should sit flat and flush in the plastic holder. If it does not sit evenly, remove it and check that you have the right side facing up. Once the battery is seated, gently press down on it to make sure it is making contact with the metal contacts inside the holder.

Test the Remote Before Closing It

Before you reassemble the remote, press each button — lock, unlock, trunk, and panic if your model has one — and watch your Ford to confirm the lights flash or the doors respond. Testing now saves you from closing the remote, discovering a button does not work, and having to open it again.

If a button does not work, remove the battery and reinsert it, making sure the positive side is facing up and the battery is sitting flat. Press the buttons again. If the remote still does not work after a second attempt, the battery may be defective (rare but possible) or the remote may have a deeper problem. Try a different new battery from the same package or store before assuming the remote is broken.

Reassemble the Remote

Align the two halves of the remote so the seams line up evenly on all sides. If your remote has a screw, insert it into the hole and tighten it with a Phillips screwdriver — snug but not so tight that you crack the plastic. If your remote has a slot, press the two halves together firmly until you hear or feel a click, which means the latch has engaged.

Once reassembled, press the buttons one more time to confirm everything still works. The remote is now ready to use. Most Ford keyless remotes run on a single battery for two to three years, depending on how often you use the remote.

What to Do If the Remote Still Does Not Work

If you have installed a fresh battery and tested all the buttons but the remote does not respond, the problem may not be the battery. Check that you inserted the battery with the positive side facing up — this is the most common mistake. Remove the battery, wait 10 seconds, and reinsert it to reset the remote's connection.

If the remote still does not work, the circuit board inside may be damaged, or the remote may need to be reprogrammed to your vehicle. Ford dealerships can reprogram a remote for a fee (typically $50 to $150) or sell you a replacement remote. Some independent locksmiths also offer remote programming at a lower cost. Before you pay for a new remote, confirm with your dealership that the old one cannot be repaired.

Where to Buy Replacement Batteries

Coin-cell batteries are sold almost everywhere. Pharmacies like CVS and Walgreens stock them in the watch and battery aisle. Supermarkets like Walmart and Target carry them near the checkout or in the electronics section. Hardware stores like Home Depot and Lowe's have them in the electrical aisle. Online retailers like Amazon sell them in bulk packs, which is cheaper per battery if you have multiple remotes or devices.

When you buy a battery, check the package to confirm it is the correct type for your remote (CR2032, CR2025, or CR2016). Most packages show which devices the battery fits — look for "car key" or "keyless remote" on the label. A single battery costs $3 to $8; a pack of two or four costs $5 to $12 total.

Frequently Asked Questions

How do I know which battery type my Ford remote uses?

Open the remote and look at the battery itself — the type is printed on the surface (CR2032, CR2025, or CR2016). If you cannot read it, check your Ford owner's manual or call your dealership with your vehicle's year and model. You can also take a photo of the battery to a pharmacy or hardware store and ask staff to match it.

Can I use a different battery type if I cannot find the exact one?

No. CR2032, CR2025, and CR2016 are different sizes and voltages. Using the wrong type may not fit in the holder, may not make proper contact, or may damage the remote's circuit board. Buy the correct type — it is inexpensive and widely available.

What if I cannot get the remote open?

If there is a screw, make sure you are using the correct screwdriver size — a Phillips that is too small will slip and strip the screw. If there is a slot, try a plastic pry tool (like a guitar pick) instead of metal, which can scratch the plastic. If the remote is glued shut, a Ford dealership can open it for you, though they may charge a small fee.

How long does a battery last in a Ford keyless remote?

Most coin-cell batteries last two to three years in a keyless remote, depending on how often you press the buttons. If you use your remote several times a day, the battery may last closer to two years. If you use it less often, it may last three years or longer.

Do I need to reprogram my remote after changing the battery?

No. Changing the battery does not erase the remote's programming. Once you install the new battery and close the remote, it should work when ready without any additional steps.
