Is your Toyota Camry key fob not working as reliably as it used to? Perhaps you’ve noticed the range decreasing, or maybe it’s stopped working altogether. One of the most common culprits is a dead battery. Replacing the battery in your Toyota Camry key fob is a straightforward process you can easily do yourself, saving you time and money compared to dealership service. This guide will walk you through each step to get your key fob back in top shape.
What Battery Does My Toyota Camry Key Fob Need?
Before you start, it’s important to know the correct battery type for your Toyota Camry key fob. Most Toyota Camry models, especially those with smart key systems, use a CR1632 battery. This is a common type of coin cell battery that provides the necessary power for your key fob’s remote functions. While it’s always best to double-check your owner’s manual, a CR1632 battery is the highly probable choice for your Camry. You can find these batteries at most drugstores, electronics stores, and online retailers.
Step-by-Step Guide to Replacing Your Camry Key Fob Battery
Replacing your Toyota Camry key fob battery is a simple task that requires no special tools beyond what’s already integrated into your key fob itself. Follow these steps to get your key fob powered up again:
Tools You’ll Need
- Your Toyota Camry Smart Key Fob
- A new CR1632 Battery (make sure you have the correct replacement)
- The mechanical key from your key fob (this acts as your tool)
Step 1: Remove the Mechanical Key
Locate the small latch or button on the side of your Toyota Camry key fob. Press and hold this latch while simultaneously pulling out the mechanical key. This key is designed to be used in emergencies and also serves as the tool to open the key fob casing.
Step 2: Open the Key Fob Casing
With the mechanical key removed, you’ll notice a narrow slot where the key was housed. Insert the end of the mechanical key into this slot.
Gently twist the mechanical key. This will apply leverage and pop open the two halves of the key fob casing. You might hear a click, and the casing should separate easily.
Step 3: Access and Replace the Battery
Once the casing is open, you’ll see the circuit board and the battery. The battery is usually located on the back of the circuit board and held in place by small metal clips or legs.
Carefully use the end of the mechanical key or your fingernail to gently pry open these clips one at a time. This will release the CR1632 battery. Remove the old battery and take note of the positive (+) and negative (-) sides, ensuring you install the new battery in the same orientation.
Insert the new CR1632 battery, ensuring it’s securely placed under the retaining clips.
Step 4: Reassemble the Key Fob
With the new battery in place, carefully align the two halves of the key fob casing and snap them back together. You might need to apply a bit of pressure to ensure they are fully closed and secure. Finally, slide the mechanical key back into its slot until it clicks into place.
Tips to Extend Your Toyota Key Fob Battery Life
To maximize the lifespan of your Toyota Camry key fob battery, consider these tips:
- Keep your key fob away from electronic devices: Electronic devices like cell phones, laptops, and TVs emit signals that can cause your key fob to constantly “wake up” and search for a signal from your car, even when you’re not using it. This constant activity drains the battery faster. Try to store your key fob at least a meter (approximately 40 inches) away from these devices when not in use.
- Avoid extreme temperatures: Excessive heat or cold can negatively impact battery performance and lifespan. Avoid leaving your key fob in direct sunlight or freezing temperatures for extended periods.
- Use only high-quality batteries: While cheaper batteries might seem tempting, investing in reputable brands of CR1632 batteries can ensure longer life and more reliable performance for your Toyota Camry key fob.
Where to Buy CR1632 Batteries
You can easily find CR1632 batteries at a variety of locations:
- Drugstores: Most pharmacies like Walgreens or CVS carry CR1632 batteries in their battery or electronics sections.
- Electronics Stores: Retailers like RadioShack, Best Buy, and Batteries Plus are good sources for various batteries, including CR1632.
- Online Retailers: Amazon, Walmart, and other online stores offer a wide selection of CR1632 batteries, often at competitive prices.
Conclusion
Replacing the battery in your Toyota Camry key fob is a simple and cost-effective DIY task. By following these steps, you can quickly restore the functionality of your key fob and avoid unnecessary trips to the dealership. Keeping a spare CR1632 battery on hand can also be a proactive measure to ensure you’re never caught off guard by a dead key fob battery. Enjoy the convenience of your fully functional Toyota Camry smart key!
