Is your 2012 Toyota Yaris key fob not working as reliably as it used to? A common culprit is often a low or dead battery. Understanding how to address your 2012 Toyota Yaris Key Fob Battery is essential for maintaining convenient access to your vehicle. This guide will walk you through everything you need to know about your 2012 Yaris key fob battery, from identification to replacement and troubleshooting.
It’s a familiar scenario for many Toyota Yaris owners: you approach your car, press the unlock button on your key fob, and nothing happens. Or perhaps you’ve noticed the range of your remote decreasing, requiring you to be closer and closer to your vehicle for it to respond. These are typical signs that your 2012 Toyota Yaris key fob battery is nearing the end of its life. Fortunately, replacing the battery in your 2012 Toyota Yaris key fob is a straightforward process that you can often do yourself, saving time and money compared to dealership service.
First, let’s identify the type of battery your 2012 Toyota Yaris key fob requires. Most 2012 Toyota Yaris key fobs utilize a CR2032 battery. This is a common 3V lithium coin cell battery that is widely available at drugstores, supermarkets, and online retailers. To confirm, you can usually check the markings on your old battery once you open the key fob or consult your vehicle’s owner’s manual. Having the correct battery type is crucial for ensuring proper function and longevity of your key fob.
Once you have the correct CR2032 battery, you’ll need to access the battery compartment within your 2012 Toyota Yaris key fob. The design can vary slightly depending on the exact type of fob you have, but generally, you will need a small flathead screwdriver or a similar tool to gently pry open the key fob casing. Look for a small notch or seam on the fob where you can insert the screwdriver to begin separating the two halves of the case. Be careful not to apply excessive force, as you could damage the plastic casing. Gently twist or pry until the case begins to open.

After opening the key fob, you’ll see the circuit board and the battery. Note the orientation of the old battery before removing it, paying attention to which side is facing up (+ or -). Typically, the positive (+) side faces upwards. Use your fingertip or the edge of the screwdriver to carefully remove the old battery. Avoid using metal tools to pry directly under the battery, as this could damage the battery contacts.
Now, insert the new CR2032 battery into the compartment, ensuring that the polarity is correct – the positive (+) side should be facing the same way as the old battery was positioned. Once the new battery is securely in place, carefully snap the two halves of the key fob casing back together until they are firmly closed. You should hear a click or feel them securely join.
After replacing the battery, test your 2012 Toyota Yaris key fob by attempting to lock and unlock your doors remotely. If it works, you’ve successfully replaced the battery! If your key fob still isn’t functioning correctly after a battery replacement, there could be other issues. Consider these troubleshooting steps:
- Check Battery Polarity: Double-check that you installed the new battery with the correct polarity (+ side up).
- Battery Freshness: Ensure the new CR2032 battery is fresh and not expired. Sometimes, batteries can sit on shelves for extended periods.
- Key Fob Damage: Inspect the key fob for any signs of physical damage, such as cracks or water damage, which could affect its functionality.
- Synchronization: In rare cases, after battery replacement, the key fob might need to be resynchronized with your vehicle. Consult your owner’s manual for instructions on key fob synchronization or programming, or contact a qualified locksmith or dealership.
