Is your 2017 Toyota key fob not working as reliably as it used to? You might be facing a common issue: a dying battery. Fortunately, replacing the battery in your 2017 Toyota key fob is a straightforward process you can easily handle yourself. This guide will walk you through each step, ensuring you get your key fob back in top shape and avoid unnecessary trips to the dealership for a simple battery swap. Let’s get started and restore the convenience of your remote key functions.
Step-by-Step Guide to Replacing Your 2017 Toyota Key Fob Battery
Changing the battery in your 2017 Toyota key fob is a task that requires minimal tools and time. Follow these detailed steps to get it done correctly:
-
Locate and Remove the Mechanical Key: First, find the small button on your key fob, usually a metallic or silver button positioned near the key ring. Press and hold this button. While pressing, gently pull out the mechanical key from the fob. This key is a backup to manually unlock your car door if needed.
-
Open the Key Fob Casing: Once the mechanical key is removed, you’ll see a slot or notch where the key was housed. This slot is designed to help you open the fob. Insert a small flathead screwdriver or a thin, sturdy object (like a credit card or plastic pry tool) into this slot. Apply gentle pressure and twist or pry carefully to split the key fob casing open. The fob is usually held together by clips, so you might hear a slight clicking sound as it separates. Be patient and avoid applying excessive force to prevent damage to the plastic casing.
-
Access and Remove the Circuit Board: After opening the fob, you’ll see the internal components, including a green circuit board. Carefully lift and remove this circuit board from the casing. It might be loosely placed or gently secured. Handle it with care to avoid damaging any of the electronic components.
-
Identify and Replace the Old Battery: With the circuit board removed, you’ll now have access to the battery. Take note of the battery type and orientation before removing it. Most 2017 Toyota key fobs use a CR2032 3V lithium battery. You can typically find the battery type printed directly on the battery itself. Purchase a new CR2032 battery. These are widely available at drug stores, electronics stores, and online retailers. Remove the old battery and insert the new one, ensuring the positive (+) and negative (-) sides are oriented correctly, matching the markings in the battery compartment.
-
Reassemble the Key Fob: Carefully place the circuit board back into its position within the key fob casing. Align the two halves of the key fob casing and press them firmly together until they snap back into place. Ensure the casing is completely closed and secure.
-
Reinsert the Mechanical Key: Finally, slide the mechanical key back into its slot until it clicks and locks into position.
By following these steps, you’ve successfully replaced the battery in your 2017 Toyota key fob. Test the key fob to ensure all buttons are working correctly – locking, unlocking, panic button, and remote start if applicable.
Troubleshooting Common Issues After Battery Replacement
While battery replacement is generally simple, you might encounter a few common issues. Here’s how to troubleshoot them:
-
Key Fob Not Working After Battery Change: Double-check the battery orientation (+ and – sides). Ensure the new battery is a CR2032 3V and is not expired. Also, make sure the circuit board is properly placed and the fob casing is completely closed. If it still doesn’t work, try cleaning the battery contacts on the circuit board with a cotton swab and a bit of rubbing alcohol.
-
Difficulty Opening the Key Fob: If you’re having trouble opening the fob, ensure you are inserting the screwdriver or pry tool into the correct slot and applying pressure in the right direction. Sometimes, gently wiggling the tool while applying pressure can help separate the casing. If it’s very tight, consider using a plastic pry tool to avoid scratching the plastic.
-
Key Fob Range Reduced: In rare cases, if the range of your key fob seems reduced after a battery change, it could indicate a weak battery or a minor issue with the key fob’s internal antenna. Try a different brand of CR2032 battery. If the problem persists, the key fob itself might need further inspection.
When to Consider a Full 2017 Toyota Key Fob Replacement
While a battery change solves most issues, there are situations where a full 2017 Toyota key fob replacement is necessary:
-
Lost or Damaged Key Fob: If your key fob is lost, stolen, or severely damaged (e.g., water damage, crushed), battery replacement won’t suffice. A full replacement is needed.
-
Malfunctioning Buttons or Electronics: If buttons are unresponsive even with a new battery, or if the key fob is malfunctioning in other ways, the internal electronics might be faulty. Replacement is often the most practical solution in these cases.
-
Wear and Tear: Over time, the plastic casing of your key fob can become worn, cracked, or broken. While this doesn’t affect functionality, you might prefer a replacement for aesthetic reasons or to prevent further damage to the internal components.
For a full 2017 Toyota key fob replacement, it’s best to contact a Toyota dealership like Chicago Northside Toyota. They can ensure you get the correct key fob programmed specifically for your vehicle. While aftermarket options exist, using a dealership guarantees compatibility and proper programming, which is crucial for security and functionality.
