Steps to replacing a Lincoln key fob battery

Key fobs, also known as keyless entry devices, are handy little electronic gadgets that make it possible to unlock your car doors without having to fumble for your keys.

They typically come with most new cars and trucks these days, and they’re a great convenience - until the battery dies, that is.

When the battery in your key fob starts to get weak, you’ll notice that the range at which it will unlock your doors starts to diminish.

Eventually, you may find yourself having to stand right next to your car to get it to unlock. When this happens, it’s time to replace the battery.

If you own a Lincoln, the process for replacing the battery in your key fob is pretty straightforward. Here are the steps you need to follow:

Remove Key

The first step is to remove the hidden key located inside the key fob. There will be a release on the back of the key fob that you will need to press. Then, the emergency key can be pulled out from the key fob.

Use Flathead Screwdriver

Once the key is removed, use a flathead screwdriver to pry open the key fob. Place the flathead screwdriver in the same slot the emergency key was in and open the key fob.

Do this gently as you do not want to break the key fob.

Locate Battery

Once the key fob is pried open, you will see the battery located inside. It is a small, round battery with plus and minus signs on it.

Remove Battery

Using the flathead screwdriver again, remove the old battery from the key fob. Be careful not to touch the wires or circuits with the screwdriver as this could damage them.

If you haven't already bought a new battery, save the old one and take it to the store with you so you can get the right size and type of battery to replace it.

Install New Battery, "+" Side Down

Once the old battery is removed, take the new battery and install it in the key fob with the “+” side facing down.

Assemble Key Fob

Now, you can put the key fob back together. Be sure that it is snapped securely closed. There shouldn't be any gaps or spaces visible.

Test Key Fob

Now it’s time to test the key fob to make sure it is working properly. Get in your car and try pressing the button to see if the doors unlock. If they do, then you have successfully replaced the battery in your Lincoln key fob!

If you don't feel comfortable doing this yourself, you can always take it to the dealership or a nearby car stereo shop, and they will be able to do it for you.

Key fob batteries are not all created equal, so be sure to get one that is compatible with your specific key fob. They usually come in two common sizes: CR2032 and CR2025.

However, double-check with your Lincoln's owner’s manual or by opening the key fob to see which size you need before heading to the store.

It is also a good idea to buy extras, so you always have a few on hand in case the battery dies again. That way, you won’t be caught without a working key fob!

Lincoln's key fob isn't working - What could be wrong?

If you have replaced the key fob battery, but it still isn’t working, there are a few other things that could be wrong.

Loose Battery Cables

It is possible that your Lincoln battery cables are not tight enough. You can check this by opening the hood of your car and checking that the cables are secured.

Make sure that the vehicle is turned off before doing this. Then, use pair of pliers or a crescent wrench to tighten the battery cables if they are loose.

Corroded Battery Terminals

Correded batteries

When you are checking the battery cables, also take a look at the battery terminals to see if they are corroded.

Corroded battery terminals can prevent the flow of electricity and cause all sorts of problems. If you see any corrosion, clean it off with a wire brush or by using a special terminal cleaner.

You can also try using sandpaper to remove the corrosion. Once you have cleaned the terminals, be sure to apply a thin layer of petroleum jelly to prevent future corrosion.

If your key fob still isn't working after checking these things, there is likely an issue with the key fob itself, and it will need to be replaced.

Car isn't in park

Did you accidentally turn your vehicle off and leave it in drive or neutral? If the car isn't in park, then the key fob won't work. Put the car in park and then try again.

Dead Vehicle Battery

If tightening and cleaning the battery cables and terminals doesn't fix the problem, then it is possible that your vehicle's battery is dead.

This can happen if you let the car sit for too long without starting it or have been using many electrical accessories recently.

To test whether or not the battery is the issue, try jump-starting your car. If it starts, then you know that the battery was the problem.

If jump starting doesn't work or you don't have jumper cables, you can try giving the battery a charge with a battery charger.

Once the battery is charged, try starting the car again. If it starts, then you will need to take it for a drive to allow the alternator to recharge the battery.

If your car still won't start, then there could be a problem with the starter or ignition system, and you will need to have it checked by a mechanic.

Damaged Key Fob

Have you dropped your key fob or gotten it wet? If so, then this could be the reason why it isn't working.

If the key fob has been damaged, then it will need to be replaced. You can buy a new one from the Lincoln dealership.

You can also find them online, but be sure that you are getting one that is compatible with your car.

How much is a Lincoln key fob replacement?

Depending on the year and model of your Lincoln, the replacement key fob can cost anywhere from $120-$400.

The reason why key fobs are so expensive is that they contain many electronic components, and they need to be programmed to work with your car.

Sometimes you will have to take your new key fob to the dealership to have it programmed.

If you have lost your only key fob, then you will need to get a new one from the Lincoln dealership and have it programmed. This can be very expensive.

If you have two key fobs, you can save money by taking one of them to a locksmith or car key programmer to make a duplicate. This will be much cheaper than getting a new key fob from the dealership.

How do you start the car with a dead key fob?

If your key fob battery is on its way out or has already died, you can still start your car using the emergency key that is stored inside the key fob.

To do this, simply insert the emergency key into the keyhole in the door and turn it to unlock the door. Once the door is unlocked, press your foot on the brake, and press the start button with the key fob.

The vehicle should recognize the emergency key and start the car by doing this.

If your car doesn't have a key fob, then you will need to use the physical key to unlock the door and start the ignition.
