Understanding Your Hyundai Car Key Fob
Before diving into the process of changing the battery, it’s important to familiarize yourself with the different types of car key fobs used in Hyundai vehicles. While many modern Hyundais utilize keyless entry systems with integrated remote start, the battery replacement procedure remains relatively consistent across various models.
Key Fob Types
Hyundai car key fobs typically fall into two main categories:
- Traditional Key Fobs: These fobs feature a physical key blade alongside the buttons for locking, unlocking, and trunk release. Battery replacement usually involves a small screw on the back of the fob.
- Smart Keys: These keyless entry systems utilize a proximity sensor and a buttonless design. In some cases, the battery might be integrated into the key itself and require specialized tools for replacement.
Identifying the Battery Type
The specific type of battery required for your Hyundai car key fob depends on the model year and key fob type. Refer to your owner’s manual for precise information. Common battery types include:
- CR2032
- CR2016
- CR1616
It’s important to note that using an incorrect battery size or type can damage your key fob. Always double-check the battery specifications before purchasing a replacement.
Preparing for Battery Replacement
Before you begin the battery replacement process, gather the necessary tools and materials. Having everything readily available will make the process smoother and more efficient.
Tools and Materials
- A new battery of the correct type and size for your Hyundai car key fob
- A small flat-head screwdriver (or a specialized key fob opening tool)
- A small, clean cloth or paper towel
Disconnecting the Key Fob
To avoid any potential issues with the key fob’s electronic components, it’s advisable to disconnect it from the ignition before starting the battery replacement process.
Simply remove the key from the ignition and ensure the key fob is not in range of the vehicle’s receiver.
Identifying the Right Battery
Before you begin the process of replacing your Hyundai car key battery, it’s crucial to identify the correct replacement. Hyundai utilizes a variety of key fob models, each with its own specific battery type and size.
Battery Type and Size
Most Hyundai key fobs utilize standard coin cell batteries, commonly found in a range of electronic devices. The most frequent battery type is a CR2032, a 3-volt lithium battery with a diameter of 20 millimeters and a height of 3.2 millimeters. However, some newer Hyundai models may use different battery types, such as CR2016 or CR2450.
Checking Your Key Fob
To determine the precise battery type for your Hyundai key fob, carefully examine the battery compartment. It’s usually located on the back of the key fob and may require a small tool, such as a flathead screwdriver or a dedicated key fob battery replacement tool, to pry it open.
The battery itself will usually be labeled with its specifications, including the type and voltage. If you’re unsure, you can also consult your vehicle’s owner’s manual, which should list the recommended battery type for your specific key fob model.
Where to Find Replacement Batteries

Ensuring a Secure Work Environment
It’s essential to work in a well-lit and clean environment to avoid accidentally dropping the small battery or damaging the key fob.
Having a soft surface, such as a microfiber cloth or a non-slip mat, underneath the key fob can also help prevent scratches or damage.
Understanding the Risks
While replacing a car key fob battery is a relatively simple task, it’s important to be aware of potential risks.
- Damage to the Key Fob: If you use excessive force when opening the battery compartment, you could damage the key fob’s plastic casing or internal components.
- Battery Leakage: If the battery is not installed correctly or if it leaks, it can damage the key fob’s circuitry.
- Accidental Activation: If the key fob is accidentally activated during the battery replacement process, it could cause unexpected car behavior.
By taking precautions and following the steps carefully, you can minimize these risks and successfully replace your Hyundai car key fob battery.
