Identifying the Battery Type
Your 2020 Toyota RAV4 Hybrid uses a coin-shaped lithium battery for its key fob. This battery is typically found inside the key fob itself, secured with a small screw or clip.
To identify the battery type, you can refer to the owner’s manual for your vehicle. It should provide specific details about the battery size and type required for your key fob. Alternatively, you can take the key fob to a local hardware store or automotive parts retailer and ask an employee to help you identify the battery.
Once you have identified the battery type, you can purchase a replacement from the same hardware store or retailer. Make sure to select a battery that matches the size and voltage requirements of your key fob. It is not recommended to use an incorrect battery type or size, as this could damage the key fob or its internal components.
| Battery Type | Size | Voltage |
|---|---|---|
| CR2025 | 20mm diameter, 2.5mm thick | 3V |

Testing the Key Fob Functionality
Before proceeding with the battery replacement, it’s crucial to ensure that the key fob malfunctions are indeed caused by a depleted battery. Here’s a step-by-step guide to test the functionality of your key fob:
-
Check the Range: Stand a few meters away from your car and press the unlock or lock button. If the car doesn’t respond, it indicates a potential battery issue.
-
Inspect the LED Light: Press any button on the key fob and observe the LED light. A weak or non-functioning light can be a sign of a low battery.
-
Try Other Buttons: Test the functionality of all the buttons on the key fob, including the panic, trunk, and hazard light buttons. If multiple buttons are not working, a depleted battery is likely.
-
Use a Voltmeter: For a more precise test, you can use a voltmeter to measure the battery voltage. A healthy battery should register around 3 volts.
-
Observe the Key’s Physical Condition: Check if the key fob has any visible damage, such as cracks or breaks. These can compromise the battery’s performance.
| Battery Type | Voltage | Replacement Frequency |
|---|---|---|
| CR2032 | 3 Volts | Every 2-3 years |
