Identifying the Key Battery Type

However, before you can proceed with the battery replacement, it’s important to first identify the key battery type. This will ensure that you purchase the correct replacement battery and avoid any potential issues or frustrations down the line.

Checking the Car Manual

One of the easiest ways to determine the battery type for your Hyundai car key is by referring to the car manual. The manual contains a wealth of information about your specific Hyundai model, including details about the key, its battery, and the replacement process. Consult the manual and look for the section that relates to the key fob or remote entry system. Here, you should find information about the battery type, along with any specific instructions or precautions for changing it.

Inspecting the Key Fob

If you don’t have access to the car manual or prefer a more hands-on approach, you can also inspect the key fob itself to identify the battery type. Most Hyundai car keys have a small compartment that houses the battery. To access this compartment, locate the small slot or button on the key fob, usually located on the side or bottom. Use a small tool, such as a flathead screwdriver or a coin, to gently pry open the compartment cover.

Once the compartment is open, you’ll typically find the battery sitting snugly inside. Take note of the battery type, which is usually indicated on the battery itself. Common battery types for Hyundai car keys include CR2032 and CR2025. Ensure you have the correct battery type so that you can purchase the appropriate replacement.

If you’re unable to find the battery type on the battery itself, you may need to remove the battery and check for any markings or specifications on the back of the key fob. Carefully remove the battery using a small tool or your fingers, taking care not to damage any components. Once you have the battery in hand, check for any markings or codes that indicate the battery type.

Identifying the battery type is the crucial first step in changing the battery in your Hyundai car key. By referencing the car manual or inspecting the key fob, you can confidently determine the correct battery type and proceed with the replacement process. With a new battery installed, your key will be ready to continue providing you with easy access to your Hyundai vehicle.
