Where to Get Car Remote Battery Replaced (4 Places & Cost)

Like most people, you rely on your car remote to make your daily commute a little bit easier. With the press of a button, you can unlock your car and be on your way. But what happens when your car remote stops working? Unfortunately, the most likely culprit is a dead battery. 

In this post, we’re going to take a look at where you can get the battery replaced, what kind of battery you need, how much it will cost, and even how to do it yourself. Let’s get started!

What Happens When The Car Key Battery Is Low?

One of the first things you will notice when the car key battery gets low is that the key fob becomes less responsive. Fortunately, most key fobs have a security chip inside the fob that functions even without battery power. This way, you can start your car even with a dead key remote battery.

However, if the battery is running low, you may need to get close to your car for the key to work. Additionally, you may have to press and hold the start button for a few seconds when attempting to start your vehicle.

Many key fobs used in keyless entry systems have a physical “slide-out key” for emergencies. This allows the driver to open the doors of the car when the remote battery or car battery gives up on you.

How Can You Tell If The Car Key Battery Needs A Replacement?

The first sign that you will soon need to replace the car key battery is that it becomes weaker and loses its range. This means the key fob or remote may become less responsive, and you’ll more frequently have to press the button multiple times and even hold it for a few seconds for it to respond.

In the worst case, your car won’t recognize the key fob, and you may end up struggling to get inside your car and get it started. If you’ve noticed any of these signs, it’s probably best to get the car fob battery replaced as soon as possible.

And if you find yourself in this situation, don’t forget about the slide-out key we mentioned above.

  2. Next, use a suitable-sized flat-head screwdriver to open the cover. On some key fobs, it requires loosening a screw to pry it open.
  3. Gently remove the old battery from the compartment, paying attention to the polarity (positive side vs. negative side) of the battery so that you can properly install the new one.
  4. Take the new battery and insert it into the compartment, ensuring that the polarity of the new battery is facing the same way as the old battery.
  5. Close the battery compartment, ensuring that it is securely closed, by replacing the screw or sliding it shut.
  6. Test your remote to ensure it is working properly by pressing a button. If the remote doesn’t work, double-check to ensure that the battery is properly installed and the compartment is properly closed.

And that’s it! With just a few simple steps, you’ll be able to change the battery in your car remote and get it working again. Now you can carry on with your day without worrying about the remote dying on you unexpectedly.
