The 2017 Lexus IS300 key fob is a marvel of modern technology, allowing you to lock, unlock, and even start your car remotely. But what happens when your key fob starts acting up? A dead or dying battery is often the culprit. If you’re experiencing inconsistent key fob performance like reduced range or unresponsive buttons, it’s probably time for a quick battery swap.
This comprehensive guide will walk you through everything you need to know about your 2017 Lexus Is300 Key Fob Battery, from identifying the signs of a dying battery to step-by-step replacement instructions. We’ll also provide some helpful troubleshooting tips to get you back on the road quickly.
Recognizing a Dying Key Fob Battery in Your 2017 Lexus IS300
Before you start digging for a new battery, it’s essential to confirm that the battery is actually the issue. Look out for these telltale signs:
- Decreased Range: Do you find yourself having to stand closer to your IS300 for the key fob to work? A weakening battery often manifests as reduced signal strength.
- Intermittent Functioning: Are your key fob buttons working only sporadically, even when pressing firmly? This inconsistency is a strong indicator of a battery on its last legs.
- Dashboard Warning: Some 2017 Lexus IS300 models might display a “Key Fob Battery Low” warning on the dashboard, providing a clear signal for battery replacement.
If any of these resonate with your Lexus IS300 key fob experience, a fresh battery is likely the solution.
2017 Lexus IS300 Key Fob Battery Replacement: A Step-by-Step Guide
Replacing the battery in your 2017 Lexus IS300 key fob is a surprisingly simple task that you can handle right at home. Here’s a detailed guide:
What You’ll Need:
- A new CR2032 battery (widely available at most stores)
- A small flat-head screwdriver
- Optional: A small plastic pry tool (to prevent scratching)
Instructions:
- Locate the Key Release Button: On the back of your Lexus IS300 key fob, find the small, recessed button.
- Release the Mechanical Key: Press and hold the key release button, then gently slide the mechanical key out of the fob.
- Open the Key Fob Casing: Use the flat-head screwdriver (or a plastic pry tool) to carefully pry open the key fob casing. Insert the screwdriver into the notch where the mechanical key was located and gently twist to separate the two halves of the fob.
- Remove the Old Battery: The CR2032 battery will be clearly visible. Gently pry it out using the screwdriver or your fingernail.
- Install the New Battery: Insert the new CR2032 battery, ensuring the positive (+) side faces upwards.
- Reassemble the Key Fob: Align the two halves of the key fob and press them firmly together until they snap shut.
- Reinsert the Mechanical Key: Slide the mechanical key back into its slot on the fob.
That’s it! Your 2017 Lexus IS300 key fob should now be back to full functionality.
Troubleshooting Key Fob Issues
Even after replacing the battery, you might still encounter issues with your Lexus IS300 key fob. Here are a few common problems and solutions:
Problem: The key fob still doesn’t work after battery replacement.
Possible Solutions:
- Check Battery Orientation: Make sure the new battery is installed correctly with the positive (+) side facing up.
- Clean the Battery Contacts: Over time, the battery contacts inside the key fob can accumulate dirt or corrosion. Use a cotton swab and a small amount of rubbing alcohol to clean the contacts gently.
- Reprogram the Key Fob: In some cases, you might need to reprogram the key fob to your Lexus IS300 after a battery change. Consult your owner’s manual for instructions on how to do this.
Problem: The key fob range is still limited.
Possible Solutions:
- Interference: Other electronic devices, particularly those operating on similar frequencies, can interfere with your key fob signal. Try using your key fob away from other electronic devices.
- Weak Key Fob Antenna: If your Lexus IS300 is an older model, the antenna inside the key fob might be damaged or worn out. Contact a qualified automotive locksmith or dealer for assistance.
