How Much Does It Cost To Replace A Key Fob Battery?

Today’s key fobs are capable of much more than just unlocking and starting a car. They serve as both a convenience item and a strong theft deterrent.

However, key fob replacement is a problem. So, you may want to know how much does a key fob battery replacement costs.

Key fob batteries typically cost $10 or less. However, some fobs require two batteries that increases the cost.

Even so, there are a few things that go into determining the approximate replacement cost such as the vehicle model, key fob type, programing, etc. In this article, I am going to cover all these factors.

Can Key Fob Batteries Be Replaced?

Yes, you can replace the batteries in your key fob, and it’s a lot easier than you might think. A little flat-tipped screwdriver and a new battery are all you’ll need.

The key fob battery is likely dead if the range of your car key fob has decreased, the buttons aren’t reacting to your touch, or the vehicle is having difficulties recognizing its presence.

What Do I Do If My Key Fob Battery Is Low?

First and foremost, make sure that the keyless remote battery in your car is never low. There is, however, a way out if you notice that the battery is low.

The remote or key fob in most modern cars has a security chip that functions without the use of a battery. Nevertheless, it only works when the car is within a short distance.

As a result, you’ll need to come quite near to the car and press the start button on your smart fob to start it.

Meanwhile, a complete replacement is the best answer for a low-keyless remote battery. Other remote management techniques may work in the meanwhile. But you can’t continue to rely on them to prevent the unexpected from happening.

How Much Does It Cost to Replace Key Fob Battery?

Key fob battery replacement cost depends on a few things such as Key fob type, vehicle, location, and dealer. The battery itself costs $10 or less.

The dealer may not charge you anything for the labor as it takes a few mins. Some key fob requires programming through software after replacing the battery.

In that case, it will cost you more than just the battery. Next, some key fobs require two batteries resulting in twice as much cost.

Then there is the vehicle model. Some vehicle key fobs are very expensive and the replacement cost of those models can be pretty costly.

How Do I Change The Battery On My Car Key Fob?

The procedure of changing the battery of a key fob is easy.

Follow these simple steps to do it yourself:

Step 1: Find the notch to open the fob

Because the notch may not be visible, this is the most difficult aspect. There is a little gap at the top of some devices. But you may need to inspect the connection point where the emergency key slips out on others.

Step 2: Use the screwdriver to pop it open

Wedge the flat-tipped screwdriver into the slot to open it. The entire device should split down the middle, revealing a circular battery inside.

Step 3: Identify the battery type

Look attentively at the battery inside to see if there are any marks that will identify the battery’s model. Purchase a replacement battery of the same type.

Step 4: Replace the old battery with a new one

If you use your finger to pop the old batteries out, it should easily come out. The new battery replaces the old one and fits well.

Step 5: Snap the fob shut

Close the key fob now that you’ve got a fresh key in place. When you squeeze it, it should snap back into place.

You may need to change the battery every five years or so, depending on the quality of the new battery you buy, how often you drive, and whether the battery is a proximity key that drains faster.

How Long Should The Key Fob Battery Last?

Key fob batteries typically last three to four years when used regularly. The battery, on the other hand, can survive for 4 to 7 years if you want to take particular care to extend its life.

Here are several key fob examples, along with how long their batteries last:

Smart key fob: These have a transponder that allows you to open your automobile doors without using a key. In most cases, the batteries last three to four years.

Remote key fob: This one has the same feature as the smart key fob.

Fobik key fob: A fobik is a remote control that acts as a key to start your automobile. These batteries have a lifespan of only 2.5 years.

How Do I Know If My Key Fob Needs A New Battery?

In the long term, failing or defective batteries might be troublesome. You can tell if it’s time to replace the key fob battery by looking for these three symptoms.

Weak Signal Strength

For an SUV or vehicle, the majority of fob keys have a signal strength range of 50 feet. Once the battery dies, the fob’s transmitter range and power will diminish.

If your key fob is unable to lock or unlock your vehicle, it will need to be replaced.

Inconsistent Operation

When you click a button on a key fob, it usually becomes active, suggesting that it is working properly. There are also newer varieties that begin the igniting process.

The fob is usually inserted into a dashboard slot or sends an electrical signal to the vehicle’s ECU. A motorist can then hit the start button. This feature’s inconsistency indicates that the battery is running low.

Unlocking doors requires several clicks

A key fob normally just requires one click to unlock your vehicle’s doors. It may be necessary to make a few more clicks at times. If this is the case, the battery is failing and must be changed before it dies.

It’s vital to keep in mind that entirely draining your key fob battery may cause the sensors to reset. They won’t be able to connect with your automobile if this happens.

Can You Start A Car With A Dead Key Fob?

The security chip within the fob works without a battery in most automobiles, but only within a very short range. Even if the fob’s battery is dead, it should still be able to start the car.

To start the engine, you may need to place the smart fob closer to the “Start” button or insert it into a particular slot. Directions may be found in your owner’s handbook.

A standard mechanical key might also be kept within the fob. If the fob battery dies or the car’s main battery is drained, this key can access the driver’s door.

What Battery Goes In a Key Fob?

The CR2032 is the most common automobile key fob battery. This is a very common car key fob battery. The numbers on the battery show the diameter (width) and height (height) of the battery (tall).

The 2032 battery is 20mm in width and 3.2mm in height. The letter C denotes a lithium-ion battery. The R denotes the form, which is round.
