Where To Get Car Remote Battery Replaced? (4 Places & Installation Guide)

Is your key fob less responsive or not unlocking your car? Chances are, you are dealing with a low or dead battery.

Today, key fobs or remote keyless systems are a standard in most cars, from SUVs to Pickups. Whether as a standalone unit or part of the metal key itself, key fobs offer you the convenience of locking and unlocking your vehicle, anytime. They also act as a theft deterrent.

But since these handheld devices depend on battery power, they can stop working at the worst time. This can be frustrating, especially if you don’t know where to get the car remote battery replaced.

But worry not! We are here to help you. This guide will help you locate potential places where you can replace your car key remote battery.

How Does a Key Fob Work?

Once you push a button on the key fob, it sends distinctly coded signals via a radio transmitter to a receiver integrated into a car door latch. As a result, it opens or closes your car door.

It achieves this through a radio frequency identification (RFID) system that works like an electronic barcode for identification. RFID performs the same function as a credit card barcode.

The only difference between them is the placement. The key fob and the RFID don’t need to be stationary for frequency transmission. If you press the button on the car remote within the proximity of the RFID device, it triggers the door’s locking mechanism to grant your access to the car.

In addition to locking and unlocking the car door, key fobs serve other purposes, including:

  • Controlling windows: In newer models of cars, like the Volkswagen Tiguan, you can press a button on the key fob to roll down the windows.
  • Self-parking and summoning: Other remote car keys allow users to summon their vehicles. Owners of the Hyundai Sonata, Kia EV6, and Genesis GV60 can enjoy this feature.

What Happens When the Car Key Battery is Low?

What Happens When the Car Key Battery is Low?

A key fob battery powers the car keys and runs the remote function. When it’s weak, you might not start your vehicle remotely, especially if it uses the push button to start technology.

Luckily, most vehicles come with a security chip within the key fob or car remote that function without battery power. The only catch is it only works from a very close range to the cars. That means you must get close to your car and long-press the start button on the key fob to start it.

Some key fobs have an emergency blade (E-blade) or physical key placed inside them. You just need to pull it out and open the driver’s side door when faced with a dead battery.

However, the best solution for this problem is key fab battery replacement.

How Can You Tell If the Car Key Battery Needs a Replacement?

Usually, when the car key remote battery becomes weaker, the transmitter integrated within the device loses its range. As a result, you might notice the following signs:

  • The key fob or car remote becomes less responsive
  • You have to press the button repeatedly or long-press before the vehicle’s door unlocks
  • The car fails to recognize the key remote

If you observe these signals, it’s time to get a new battery for your car key fob.

How To Change Car Remote Battery?

Once you’ve found the battery for your key fob, you will have no issues replacing it yourself. Follow the steps below to make your Subaru, Honda, Mazda, or Toyota key fob battery replacement a breeze.

Step 1: Open the car key remote or fob

It’s easy to pop open a key fob to replace the battery. Locate the notch in the seam and pry the remote into two halves. In most cases, you might not be able to open the fob with your hands. So, find yourself a small flat-head screwdriver and pry it open. Some key fobs might require you to loosen the screw holding the two halves together before you can open it.

Step 2: Confirm the batter terminals–positive and negative ends

The small coin-like battery in most key fobs comes with a plus sign and minus sign embedded in it. After opening the remote, note the battery positioning since the new battery will need to go in the same way the old battery got inserted.

Step 3: Remove the Old Battery

In most cases, the old battery will pop out of its place because of the inbuilt spring. But if it doesn’t, check if any clips are holding the battery. Move the clips to the side and slide out the dead battery. Sometimes, you might need to use a flat-bladed screwdriver to pry out the old battery. But be gentle to avoid any damage to the key fob circuits.

Step 4: Slide in the new battery and close the key remote

Once you remove the old battery, insert the new battery in the same orientation. Next, assemble the remote by snapping the separate pieces together. Finally, ensure everything works perfectly.

Closing Thoughts

While key fobs batteries can last between 3 to 4 years, they eventually drain out. When this happens, you will lose remote access to your car and become stranded.

However, you can avoid such embarrassing situations by getting your car key remote battery replaced. You can purchase the appropriate key fob battery at online stores like Amazon and Walmart or your local auto part shop.

Replacing the old battery with a new one is a straightforward process, and you can do it yourself. However, if your key fob is complicated, take it to a key fob replacement shop like BatteriesPlus, Autozone, or Keyless.
