The key to maintaining your Toyota Rav4 Hybrid is keeping all of its components in working order. This includes replacing the battery in your key fob when it starts to die. A dead battery can prevent you from locking or unlocking your car, which can be a major inconvenience. Thus, knowing how to change the car-key battery for a 2020 Toyota Rav4 Hybrid is essential for all Rav4 Hybrid owners to guarantee the vehicle’s good condition.
Fortunately, changing the battery in a 2020 Toyota RAV4 Hybrid key fob is a relatively simple process that can be completed in just a few minutes. You will need a new CR2032 battery and a small screwdriver. First, locate the small screw on the back of the key fob and remove it. Then, gently pry open the key fob using the screwdriver. Be careful not to damage the key fob or its components. Once the key fob is open, you will see the old battery. Remove the old battery and replace it with the new one. Make sure the positive (+) side of the battery is facing up. Finally, snap the key fob back together and replace the screw.
Identifying the Type of Key Battery
Identifying the correct battery for your 2020 Toyota RAV4 Hybrid is essential for ensuring the proper functioning of your vehicle’s key fob. There are typically two types of batteries used in Toyota key fobs: coin-type batteries and button-type batteries.
To determine the type of battery in your RAV4 Hybrid’s key fob, follow these steps:
- Locate the key fob’s physical key. It is usually stored within the fob itself and can be released by pressing a button.
- Once the key is released, locate the battery compartment. It is typically a small compartment secured by screws or clips.
- Carefully open the battery compartment. The battery should be visible, with its terminals exposed.
- Examine the battery to determine its type. Coin-type batteries are typically round and flat, while button-type batteries are smaller and cylindrical.
Once you have identified the type of battery in your RAV4 Hybrid key fob, you can proceed to purchase a replacement battery of the same type and specifications. This information is usually indicated on the battery itself or in your vehicle’s owner’s manual.
| Battery Type | Description |
|---|---|
| Coin-type (CR2032) | Round, flat battery with a diameter of 20mm and a thickness of 3.2mm |
| Button-type (CR1632) | Cylindrical battery with a diameter of 16mm and a height of 3.2mm |
Locating the Key Fob’s Battery Compartment
To initiate the battery replacement process for your 2020 Toyota Rav4 Hybrid’s key fob, you must first locate the battery compartment. Follow these detailed steps to access it effortlessly:

- If you’re still having problems, take the key fob to a locksmith or mechanic to have it tested.
- You can also try to reset the key fob by pressing and holding the lock and unlock buttons simultaneously for 10 seconds.
- If none of these steps work, there may be a problem with the car’s receiver. You can try taking the car to a dealership or mechanic to have the receiver tested.
| Battery Type | Voltage | Size |
|---|---|---|
| CR2032 | 3V | 20mm x 3.2mm |
Finding Your Key Battery
Locate the small, usually round or rectangular, battery in your key fob. It will typically be secured by a small screw or held in place by a clip.
Replacing the Battery
Use a small screwdriver or a key to open the key fob housing. Carefully remove the old battery and replace it with the new one, making sure to observe the correct polarity (+ and -). Reassemble the key fob and tighten the screw or clip.
Tips for Extending Key Battery Life
Avoid Excessive Button Pressing
Limit unnecessary button presses on your key fob, as each press consumes battery power.
Keep the Key Fob Away from Heat
High temperatures can degrade the battery’s performance and lifespan. Avoid leaving your key fob in direct sunlight or near heat sources.
Avoid Frequent Key Fob Replacement
Using aftermarket key fobs or generic batteries may compromise battery quality and reduce longevity. Stick to manufacturer-recommended batteries and key fobs for optimal performance.
Disable Unnecessary Key Fob Features
If your key fob has programmable features, consider disabling any unnecessary options that consume battery power, such as remote start or trunk release.
Maintain a Clean Key Fob
Debris and dirt accumulation on the key fob’s contacts can disrupt battery connection. Regularly clean the key fob with a soft cloth to prevent this issue.
Use the Key Manually Occasionally
Occasionally inserting the physical key into the ignition can “wake up” the key fob and extend its battery life.
Store the Key Fob Properly
When not in use, store the key fob in a cool, dry place away from moisture and extreme temperatures.
Replace the Battery Regularly
Even with proper maintenance, key fob batteries will eventually deplete. Monitor the battery level and replace it as soon as it shows signs of weakening.
Additional Troubleshooting Measures
10. Verify Battery Compatibility
Problem: The key fob does not function after replacing the battery.
Solution: Ensure the battery you installed matches the original specifications. Refer to your vehicle’s owner’s manual for the correct battery type. Different key fob models may require different battery types.
Detailed Explanation:
Key fob batteries come in various sizes and voltages, and using an incompatible battery can lead to malfunctions. Each key fob model is designed to operate with a specific battery type based on its power consumption and transmission range. Installing an incorrect battery may result in insufficient power supply, reduced signal range, or premature battery depletion.
To resolve this issue, check the battery compartment for any markings indicating the required battery type. Alternatively, consult your vehicle’s owner’s manual or a qualified technician to verify the correct battery specifications. Using the proper battery ensures optimal performance and prevents damage to the key fob’s sensitive electronics.
