1. What Type Of Battery Does My Toyota Car Key Need?

However, it’s always best to verify the specific battery type required for your particular Toyota model and year. You can find this information in your owner’s manual or by looking at the old battery after you open the key fob. Using the wrong battery type can lead to the key fob not working or even damage to the device.

- New CR2032 Battery: Ensure it’s a fresh battery for optimal performance.
- Soft Cloth: To protect the key fob from scratches.
