Just like any electronic device, your Toyota Highlander key fob relies on a battery to function. For 2018 Toyota Highlander owners, knowing the correct battery type for your key fob is essential for maintaining seamless access and vehicle operation. Replacing your key fob battery is a straightforward process, and understanding the right battery ensures you’re always ready to hit the road. This guide will walk you through identifying the correct battery and replacing it in your 2018 Toyota Highlander key fob.
Identifying the Correct Battery Type for Your 2018 Toyota Highlander Key Fob
The standard battery for a 2018 Toyota Highlander key fob is the CR2032 3V battery. This type is a common button cell battery known for its reliability and longevity, making it an ideal power source for key fobs. While CR2032 is the most likely battery for your 2018 Highlander key fob, it’s always a good practice to double-check.
Your Toyota Highlander owner’s manual is your most reliable resource for confirming the exact battery specification. You can quickly find this information in the manual’s section on key fob maintenance. Alternatively, once you open your key fob, the battery type is often printed directly on the old battery itself. Knowing the correct battery type beforehand saves you time and ensures you purchase the right replacement, keeping your key fob functioning without interruption.
Step-by-Step Guide: Replacing Your 2018 Toyota Highlander Key Fob Battery
Replacing the battery in your 2018 Toyota Highlander key fob is a simple task you can do yourself with a few easy steps. Here’s how:
-
Remove the Physical Key: Locate the small metal button on your key fob, usually positioned above the key portion. Press and hold this button while gently pulling out the physical key from the fob.
-
Open the Key Fob Casing: After removing the key, you’ll see a small slot where the key was inserted. Take a small flat-head screwdriver or a similar thin, flat object. Carefully insert the tool into this slot and gently twist or pry to split open the key fob casing. The casing is typically designed to snap apart easily.
-
Access the Circuit Board and Battery: Once the fob is open, you’ll see a green circuit board inside. Carefully lift or maneuver this circuit board to access the battery compartment underneath. Handle the circuit board gently to avoid damaging any components.
-
Replace the Old Battery with a New CR2032: Take note of how the old battery is positioned in the compartment, paying attention to the positive (+) and negative (-) sides. Remove the old battery and replace it with a new CR2032 3V battery. Ensure the new battery is inserted in the correct orientation.
-
Reassemble the Key Fob: Carefully place the circuit board back into its position within the fob casing. Snap the two halves of the key fob casing back together until they are securely closed. Finally, slide the physical key back into the key fob until it clicks into place.
What to Do If You Need a Full Key Fob Replacement for Your 2018 Toyota Highlander
While battery replacement often solves key fob issues, sometimes a full Toyota key fob replacement is necessary. If your 2018 Toyota Highlander key fob is lost, damaged, or malfunctioning even after a battery change, it might be time for a replacement.
For a complete Toyota key fob replacement, the parts department at a certified Toyota dealership, like Chicago Northside Toyota, is your best resource.
