Experiencing a spotty connection with your 20017 Lexus RX 350 key fob? Chances are, it’s time for a new battery. Don’t worry, this is a common issue and a relatively easy fix. This guide will walk you through the process of replacing the battery in your 20017 Lexus RX 350 key fob, getting you back on the road in no time.
Understanding Your Lexus RX 350 Key Fob
Before we jump into the replacement process, it’s helpful to understand how your key fob works. The key fob transmits a radio signal to your car’s receiver, allowing you to lock, unlock, and even start your vehicle remotely. This signal is powered by a small battery inside the fob. Over time, this battery will lose its charge, leading to a weakened signal and potential issues with your key fob’s functionality.
Recognizing the Signs of a Dying Key Fob Battery
Several signs can indicate your 20017 Lexus RX 350 key fob battery is dying. Keep an eye out for these common symptoms:
- Decreased Range: You may find yourself needing to be much closer to your vehicle for the key fob to work.
- Intermittent Functionality: The key fob may work inconsistently, sometimes responding and other times not.
- Warning Lights or Messages: Your Lexus may display a “Key Fob Battery Low” warning on the dashboard.
- No Response: In severe cases, the key fob may stop working altogether.
Gathering the Necessary Tools
Fortunately, replacing your key fob battery is a straightforward process that doesn’t require any specialized tools. Here’s what you’ll need:
- New Battery: The 20017 Lexus RX 350 key fob uses a CR2032 battery, readily available at most electronic and automotive stores.
- Small Flat-Head Screwdriver: This will be used to open the key fob casing.
- Plastic Prying Tool (Optional): While not mandatory, a plastic prying tool can help prevent damage to the key fob casing when separating the halves.
Replacing the Battery: Step-by-Step Guide
Now, let’s walk through the simple steps involved in replacing your Lexus RX 350 key fob battery:
- Locate the Release Button: On the backside of your key fob, find the small release button or switch.
- Release the Mechanical Key: Press the release button and gently slide out the mechanical key from the fob.
- Separate the Fob Casings: Using a small flat-head screwdriver or a plastic prying tool, carefully pry open the key fob casing. Start from the side where the mechanical key was released, applying gentle pressure until the two halves separate.
- Remove the Old Battery: Once the casing is open, you’ll see the CR2032 battery sitting in a designated slot. Carefully remove the old battery, noting the positive (+) and negative (-) sides.
- Install the New Battery: Insert the new CR2032 battery into the slot, ensuring the positive (+) side faces up, matching the orientation of the old battery.
- Reassemble the Key Fob: Align the two halves of the key fob casing and press them together firmly until they snap back into place.
- Reinsert the Mechanical Key: Slide the mechanical key back into its slot on the key fob until it locks securely.
- Test the Key Fob: Press the buttons on your key fob to ensure all functions (lock, unlock, panic) are working correctly.
