Is your Lexus GX key fob acting up? Perhaps you’re finding yourself closer and closer to your vehicle before it unlocks, or maybe it’s just stopped responding altogether. Before you rush to the dealership or call a locksmith, there’s a simple fix you can handle yourself: replacing the key fob battery. This straightforward task can save you time and money, getting you back on the road with a fully functional remote in minutes. This guide will walk you through each step to replace your Lexus Gx Key Fob Battery, ensuring your key is working perfectly again.
Tools You’ll Need
Before we begin, gather these minimal tools:
- A new CR1632 battery – This is the specific type of battery required for your Lexus GX key fob. You can find these at most drugstores, supermarkets, and online retailers.
- A small flathead screwdriver – Jeweler’s screwdrivers work best, but any small flathead will do. This is used for gently opening the key fob casing.
Step-by-Step Battery Replacement Process
Follow these easy steps to breathe new life into your Lexus GX key fob:
Step 1: Accessing the Key Fob Internals
The first step is to carefully open your Lexus GX key fob. Locate the small seam running around the edge of your key fob. This is where we’ll gently separate the two halves. Insert the tip of your small flathead screwdriver into this seam. Apply gentle pressure and twist the screwdriver to begin prying the case open. Work your way around the seam slowly and carefully, avoiding excessive force that could damage the plastic housing. You should hear a soft click as the two halves begin to separate.
Step 2: Battery Compartment Exposure
Once the key fob is open, carefully separate the top and bottom halves. Inside, you’ll see the circuit board and the battery compartment. The battery will be a small, round, silver disc. Take a moment to note the orientation of the old battery, specifically which side is facing upwards. This is crucial for correct installation of the new battery.
Step 3: Old Battery Removal
Now, using your flathead screwdriver again, gently pry the old CR1632 battery out of its compartment. There may be a small clip or notch holding it in place, so be patient and avoid forcing it. Leverage the screwdriver gently to lift the edge of the battery until it pops out.
Step 4: Installing the New CR1632 Battery
Take your new CR1632 battery and insert it into the battery compartment. Ensure you place it in the same orientation as the old battery you just removed – the positive (+) side should typically face upwards. Press down gently until the battery is securely seated in the compartment. You may hear a faint click as it snaps into place.
Step 5: Functionality Test
Before fully reassembling your key fob, it’s wise to test if the new battery is working. Press any button on your key fob and observe if your Lexus GX responds – the hazard lights might flash, or the doors might lock or unlock. If the vehicle responds, you’ve successfully replaced the lexus gx key fob battery!
Step 6: Key Fob Reassembly
With successful battery replacement confirmed, it’s time to close up your key fob. Carefully align the two halves of the key fob casing. Press them firmly together until they snap securely back into place. Ensure there are no gaps and the case is fully closed.
Helpful Tips for Lexus GX Key Fob Battery Longevity
- Extreme Temperature Avoidance: Prolonged exposure to high or low temperatures can shorten battery life. Avoid leaving your key fob in direct sunlight on a hot dashboard or in freezing conditions for extended periods.
- Spare Battery Readiness: Keep a spare CR1632 battery at home or in your glove compartment. This ensures you’re prepared for unexpected battery depletion and can quickly resolve the issue.
- Reprogramming Considerations: In most cases, replacing the battery is enough. However, if your key fob still doesn’t function after a battery change, or if it wasn’t working before the battery change, it might require reprogramming. Contact your local Lexus dealer or a qualified automotive locksmith for reprogramming services.
- Gentle Handling: While durable, avoid dropping your key fob frequently. Impacts can potentially damage the internal components or dislodge the battery.
Conclusion
Replacing your Lexus GX key fob battery is a simple and cost-effective DIY task. By following these steps, you can restore your key fob’s functionality and avoid unnecessary trips to a service center. Enjoy the convenience of a responsive key fob once again and the satisfaction of handling this minor car maintenance task yourself!
