Understanding Car Key Batteries
Before delving into where to find replacements, it’s essential to understand the different types of car key batteries commonly used. Car key batteries are typically CR2032 or CR2025 lithium coin cell batteries. These small, round batteries are known for their long lifespan and ability to withstand extreme temperatures. However, some newer car keys may utilize different battery types, so it’s crucial to identify the specific battery required for your vehicle model.
Identifying Your Car Key Battery
To determine the correct battery type for your car key, you can follow these steps:
- Examine your car key: Look for a small compartment or hatch on the back of your key fob. This compartment usually houses the battery.
- Check the battery label: Once you’ve opened the compartment, you’ll find the battery itself. It will typically have a label indicating its size and voltage (e.g., CR2032, 3V).
- Consult your owner’s manual: If you’re unsure about the battery type, your car’s owner’s manual will provide detailed information about your key fob and the required battery.
