If you own a 2016 Toyota Highlander, you know a reliable key fob is essential. But what happens when your key fob starts acting up? Before you panic and schedule a costly dealership visit, a simple battery replacement might be the solution. This guide will walk you through the process of replacing your 2016 Toyota Highlander key fob battery.
Signs You Need a New Key Fob Battery
A dying key fob battery often shows telltale signs. Keep an eye out for these common indicators:
- Decreased Range: Do you find yourself having to stand closer to your Highlander to unlock it? This reduced range is a classic sign of a weakening battery.
- Delayed Response: A healthy key fob should trigger your Highlander’s locks immediately. Noticeable lag between pressing the button and the car responding suggests your battery is losing power.
- Dimming Lights: Most Toyota Highlander key fobs have an indicator light that flashes when buttons are pressed. If this light appears dim or doesn’t illuminate at all, a dead battery is likely the culprit.
Replacing the Battery: Step-by-Step
Replacing your 2016 Toyota Highlander key fob battery is surprisingly straightforward. Here’s a step-by-step breakdown:
- Gather Your Tools: You’ll need a small flat-head screwdriver and a replacement CR2032 battery. These are readily available at most hardware and automotive stores.
- Open the Key Fob: Locate the small notch on the side of your key fob. Carefully insert the flat-head screwdriver and gently pry open the casing. You may hear a slight click as it separates.
- Identify and Remove the Old Battery: Inside, you’ll see the CR2032 battery. Carefully remove it by prying it up from the positive (+) side with the screwdriver. Avoid touching the battery’s flat surfaces to prevent transferring oils that can shorten its lifespan.
- Install the New Battery: Insert the new CR2032 battery, positive (+) side facing up. Make sure it’s securely in place.
- Reassemble the Key Fob: Align the two halves of the key fob and press them firmly together until you hear a click, indicating it’s securely closed.
Testing Your New Battery
After replacing the battery, it’s crucial to test if everything functions correctly:
- Lock and Unlock Your Highlander: Test both the lock and unlock buttons on your key fob to ensure they work from a reasonable distance.
- Start Your Engine: Try starting your Highlander with the key fob to verify the immobilizer chip is powered and recognized by your vehicle.
Still Having Issues?
While a battery replacement is often the solution, persistent problems might require further investigation. If you’re still experiencing issues with your key fob, consider these possibilities:
- Key Fob Programming: In some cases, your key fob might need to be reprogrammed to your Highlander. You can consult your owner’s manual or contact a Toyota dealership for assistance.
- Faulty Key Fob: While less common, a malfunctioning key fob might be the root cause. If you suspect this, a dealership or qualified automotive locksmith can help diagnose and address the issue.
