Is your Lexus Gx460 Key Fob not working? Before you assume the worst, the most likely culprit is a dead battery. Replacing the battery in your Lexus GX460 key fob is a straightforward process you can easily do yourself, saving you time and money. This guide will walk you through each step to get your remote working again. Lexus GX460 key fobs commonly use CR1632 and CR2032 batteries, which are inexpensive and widely available online or at most retailers. Typically, these batteries cost under $6.
Knowing what type of key fob you have can sometimes help in understanding the battery replacement process. While the battery replacement steps are largely similar, here’s a quick overview of common key fob types:
- Standard Remotes: Basic remotes with standard button functions.
- Flip Keys: Feature a key that flips out from the remote body.
- Remote Heads: Have a non-retractable key blade extending from the remote.
- Fobik Keys: The key is separate and hidden within the fob, not directly connected.
- Smart Keys: Often associated with push-to-start systems for enhanced convenience.
Regardless of the type, replacing the battery is usually a similar process. Let’s get your Lexus GX460 key fob working again!
Step-by-Step Battery Replacement for Your Lexus GX460 Key Fob
The method to open your Lexus GX460 key fob varies slightly depending on the model year. Follow the instructions below that correspond to your key fob style:
For Newer Lexus GX460 Models: Using the Hidden Key
Newer Lexus GX460 key fobs are designed with a hidden mechanical key to assist in opening the case.
- Locate the Hidden Key: Find the release button or latch on your key fob. Press or slide it to release the hidden mechanical key.
- Insert the Key: Once removed, you’ll see a small slot or notch exposed on the key fob casing where the key was housed. Insert the end of the mechanical key into this designated slot.
- Open the Case: Gently twist or lever the mechanical key in the slot. This should pry open the key fob case along its seam. You may hear a click as the case begins to separate.
- Access the Battery: Carefully separate the two halves of the key fob case. Inside, you will see the circuit board and the battery.
For Older Lexus GX460 Models: Prying Open the Case
Older Lexus GX460 key fobs typically require a thin, flat object to gently pry them open.
- Identify the Notch: Examine the edges of your key fob to find a small notch or seam line. This is where you’ll insert your tool to open the case.
- Insert a Thin Tool: Use a flathead screwdriver (jeweler’s size is ideal) or a similar thin, sturdy object. Carefully insert the tip of the tool into the notch.
- Pry Open Gently: Apply gentle pressure and twist the tool to pry the case halves apart at the notch. Work your way around the seam if needed, being careful not to damage the plastic casing.
- Access the Battery: Once the case is open, carefully separate the two halves to reveal the circuit board and battery compartment.
Replacing the Battery
Once you have the key fob open, the battery replacement process is the same for both types:
- Note Battery Orientation: Before removing the old battery, carefully observe how it is positioned in the case. Take note of which side is facing up (+) and down (-). This is important for correct installation of the new battery.
- Remove the Old Battery: Gently lift or slide out the old battery from its compartment. You may be able to use your fingertip or the tip of a pen to help dislodge it.
- Insert the New Battery: Place the new CR1632 or CR2032 battery into the compartment, ensuring it is oriented exactly as the old battery was (matching the + and – positions).
- Close the Key Fob: Carefully reassemble the two halves of the key fob case. Press them firmly together until they snap securely closed.
Testing Your Lexus GX460 Key Fob
After replacing the battery and reassembling your key fob, test its functionality immediately. Press each button on the key fob to ensure it is working correctly – lock, unlock, panic button, and any other functions your fob has. If the key fob still doesn’t work, double-check the battery orientation and ensure the battery contacts are clean and making good contact with the battery.
When a Battery Change Isn’t Enough
In most cases, replacing the battery will solve the problem. However, if your Lexus GX460 key fob remains unresponsive after a battery replacement, there may be a more significant issue. In such instances, you might need a complete key fob replacement or reprogramming.
