Step-by-Step Battery Replacement Guide
The opening method can vary slightly depending on the age and specific design of your Lexus GX460 key fob. Here are instructions for both newer and older models:
For Newer Lexus GX460 Models:
- Locate the Hidden Key: Most newer Lexus key fobs contain a mechanical key for emergency access. Find the release button or latch on your key fob – usually a small button or slider.
- Release and Remove the Key: Press or slide the release mechanism and pull out the hidden mechanical key.
- Insert Key into Designated Slot: Once the key is removed, you will see a slot or notch where the key was housed. This slot is specifically designed to help you open the key fob casing.
- Pry Open the Casing: Insert the end of the mechanical key into the designated slot. Gently twist or lever the key. This should separate the two halves of the key fob casing.
For Older Lexus GX460 Models:
- Identify the Notch: Examine the edges of your key fob case to find a small notch or seam. This is the point where you will pry the case open.
- Use a Thin, Flat Object: Find a thin, flat object such as a flathead screwdriver (ensure it’s small to avoid damage) or a plastic pry tool.
- Pry Open the Casing: Carefully insert the edge of your chosen tool into the notch. Gently twist or pry to separate the two halves of the key fob casing. Work your way around the seam if needed, applying gentle pressure until the case pops open.
Replacing the Battery (For All Models):
- Access the Circuit Board and Battery: Once the key fob case is open, you will see the internal components, including a circuit board. Gently lift the circuit board to reveal the battery underneath.
- Note Battery Orientation: Before removing the old battery, pay close attention to how it is positioned in the case. Note the positive (+) and negative (-) sides to ensure you install the new battery correctly.
- Remove the Old Battery: Carefully remove the old battery. You may be able to gently pry it out with your fingertip or use a small non-metallic tool if needed.
- Install the New Battery: Insert the new battery into the compartment, ensuring it is placed in the same orientation as the old one. Make sure it is securely seated and makes good contact with the terminals.
- Reassemble the Key Fob: Carefully align the two halves of the key fob casing and press them firmly back together until they snap closed. Ensure the case is fully closed with no gaps.
- Test Key Fob Functionality: Press the buttons on your key fob to test if it is working correctly. Try locking and unlocking your Lexus GX460 and testing other functions like the panic button.
Troubleshooting
If your Lexus GX460 key fob still doesn’t work after replacing the battery:
- Check Battery Contacts: Ensure the battery contacts within the key fob are clean and making good contact with the battery. You can gently clean them with a cotton swab and a small amount of rubbing alcohol if necessary.
- Battery Orientation: Double-check that you have installed the new battery in the correct orientation (+ and – sides).
- Consider Key Fob Type: Understanding the type of key fob you have can sometimes help in troubleshooting. Lexus GX460 key fobs can be categorized into types like standard remotes, remote heads, or smart keys (often associated with push-to-start). While battery replacement is similar across these types, knowing your type can be helpful for further research if needed.
When to Consider Key Fob Replacement
If a new battery doesn’t solve the problem, or if your key fob is physically damaged, you may need to consider replacing the entire Lexus GX460 key fob. For more complex issues or key fob replacement options, it’s advisable to consult with a professional automotive locksmith or your Lexus dealership.
