Toyota Corolla 2017 Key Fob Battery: Everything You Need to Know

Is your 2017 Toyota Corolla key fob acting up? Before you panic and assume the worst, there’s a good chance it’s just a dead battery. Key fob batteries don’t last forever, and thankfully, replacing them is usually a quick and easy fix. This guide will walk you through everything you need to know about your Toyota Corolla 2017 Key Fob Battery, from identifying the signs of a dying battery to replacing it yourself.

Signs Your Toyota Corolla Key Fob Battery Needs Replacing

Just like the battery in your car, your key fob battery will eventually lose its charge. Here are a few telltale signs that it’s time for a replacement:

Decreased Range: Are you finding yourself standing closer and closer to your car to get it to unlock? This is a common sign of a weakening key fob battery.
Intermittent Functioning: Does your key fob sometimes work and sometimes not? This inconsistency is another strong indicator that the battery is on its last legs.
Warning Light on Dashboard: Some Toyota Corolla models will display a warning light on the dashboard if the key fob battery is low.
Slow Response Time: Is there a noticeable lag between when you press a button on your key fob and when the car responds? A sluggish response often means the battery is struggling to provide enough power.

Replacing Your 2017 Toyota Corolla Key Fob Battery: A Step-by-Step Guide

You don’t need to be a mechanic to replace your Toyota Corolla’s key fob battery. With a few simple tools and a new battery, you can tackle this task yourself in minutes. Here’s a step-by-step guide:

Gather Your Supplies: You’ll need a new CR2032 battery (widely available at most stores), a small flat-head screwdriver or a plastic pry tool, and your Toyota Corolla key fob.
Open the Key Fob: Locate the small release tab or notch on the back of your key fob. Gently insert the flat-head screwdriver or pry tool into the notch and pry open the key fob casing. Be careful not to use excessive force, which could damage the casing.
Remove the Old Battery: With the key fob open, you’ll see the round, flat CR2032 battery. Gently pry it out using your screwdriver or pry tool. Note the position of the positive (+) side of the battery for reference.
Insert the New Battery: Place the new CR2032 battery into the compartment, making sure the positive (+) side is facing the same direction as the old battery.
Reassemble the Key Fob: Align the two halves of the key fob casing and press them together firmly until you hear a click, indicating the casing is securely closed.

Pro Tip from John Miller, Senior Automotive Technician: “If you’re having trouble prying open the key fob, try wrapping a thin cloth or a piece of tape around the end of your screwdriver or pry tool to prevent scratches.”

Testing Your New Key Fob Battery

Once you’ve replaced the battery, it’s always a good idea to test the key fob to ensure everything is working correctly. Try locking and unlocking your car, using the remote start feature (if equipped), and opening the trunk. If these functions are working properly, you’ve successfully replaced your key fob battery.
