How to Replace the Battery on a Toyota Key Fob
If you own a Toyota vehicle with a keyless entry system, you’re likely familiar with the key fob. The key fob allows you to remotely lock/unlock your car doors, open the trunk, and even start your vehicle. However, like any electronic device, the battery in your Toyota key fob may eventually need to be replaced.

Step 1: Identify the Key Fob Type
Toyota key fobs can have different designs depending on the model and year of your vehicle. To ensure you follow the right instructions, you need to identify your key fob type. Here are the three most common types:
