Car Key Battery Replacement

Sometimes, people are shocked when they notice that their car key fob battery dies so quickly. Many factors could contribute to the key fob failures, such as frequent use, exposure to moisture, humidity, and extreme temperatures.

However, having the correct info will help you avoid unnecessary expenses, save time, and bypass frustration by replacing the car batteries swiftly.

In this article, you will learn about car key battery replacements and why getting professional locksmith services remains the top solution.

Why the Battery in Your Car Is Important

Modern car keys operate through small, coin-sized batteries. When the battery power gets too low, your key fob loses functionality to start the engine remotely or turn off your alarm system. This minor issue can turn into a bothersome experience when you need to rush.

Signs That Your Car Key Battery Needs to Be Replaced

These signs will indicate your key fob battery needs replacement:

  • Your car key buttons stop responding as expected
  • Reduced range of the signal
  • Warning light or dashboard alert
  • The need to repeatedly press buttons.

Failure to detect these warning signs can result in car lockouts or getting stranded.  So, timely replacement at our locksmith shop is essential.

How to Replace Your Car Key Battery

These steps require you to have the proper tools and basic understanding.

1. Determine the Type of Battery

Most car remote systems operate using lithium batteries either as CR2025 or CR2032 types. So, open the fob with care or refer to your user guide to be certain.

2. Open the Key Fob

The case requires a small flathead screwdriver to open it up carefully. Be cautious when handling it, to prevent any damage to its internal circuit.

3. Replace the Battery

After you remove the old battery, install the correct one and close the casing.

4. Test the Key Fob

Check the signal strength by pressing every button to confirm the proper functionality.

If you want someone else to handle such tasks, feel free to call GreenPro Locksmith.

A Locksmith's Advantages Over DIY 

The urge to replace your key fob battery yourself should be avoided because not all key fobs are the same. The advanced security features in modern car keys and their unique casing designs even make DIY attempts risky.

However, professional auto locksmith services in Lithia Springs ensure that key operations will be conducted with complete precision. Due to their expertise and practical understanding, they can safely change key fobs without damaging any internal components.

Cost of a Car Key Battery Replacement

Most key batteries have a price range from $5 to $15, depending on the specific model. Getting professional services from GreenPro Locksmith is a better option with numerous benefits. Besides, we can also provide you with budget-friendly rates and quick assistance to get you back on the road.
