Luckily, replacing the battery in your 2007 Camry key fob is a simple task you can easily do yourself, saving you time and money compared to dealership service. This guide will walk you through the process step-by-step and provide all the essential information you need, focusing on the crucial detail: the 2007 Camry Key Fob Battery Size.
Understanding Your 2007 Camry Key Fob Battery
The first and most important piece of information you need is the correct battery size for your 2007 Toyota Camry key fob. The 2007 Camry key fob battery size is CR1632. This is a 3V lithium coin cell battery. Using the correct battery size is crucial for ensuring proper function and longevity of your key fob.
CR1632 Battery Specifications:
- Type: Lithium Coin Cell
- Voltage: 3V
- Dimensions: 16mm diameter, 3.2mm thickness
- Common Uses: Key fobs, watches, calculators, small electronic devices
You can find CR1632 batteries at most drug stores, electronics stores like Radio Shack or Batteries Plus, and online retailers like Amazon. It’s always a good idea to keep a spare CR1632 battery at home so you’re prepared when your key fob battery eventually needs replacing.
Step-by-Step Guide to Replacing Your 2007 Camry Key Fob Battery
Now that you know the 2007 Camry key fob battery size is CR1632, let’s get into the battery replacement process. You’ll be pleased to know that Toyota designed these key fobs with user-friendly battery replacement in mind. You won’t need any special tools, just the mechanical key that’s already part of your smart key fob.
Step 1: Remove the Mechanical Key
Locate the small latch on the side of your 2007 Camry key fob. Press and hold this latch while gently pulling out the mechanical key. This key is designed to be used for manual door unlocking and also serves as the tool for opening the key fob case.
Step 2: Locate the Pry Slot
Once the mechanical key is removed, you’ll see a narrow slot at the end of the key fob, perpendicular to where you just pulled the key from. This is the pry slot where you’ll insert the mechanical key to open the fob.
Step 3: Pry Open the Key Fob
Insert the thinner end of the mechanical key into the pry slot. Gently twist the mechanical key. This will apply leverage and pop open the two halves of the key fob casing. Don’t force it; a gentle twist should be sufficient to separate the case.
Step 4: Access the Battery
After prying open the case, you’ll see the circuit board. The battery is located on the other side of this board. The circuit board is usually held in place by a light adhesive or small tabs.
Step 5: Remove the Old Battery
Carefully lift the circuit board out of the case. You will now see the CR1632 battery. It’s typically held in place by small metal legs or clips. Gently use your fingertip or the mechanical key to spring these legs open one at a time to release the old battery. Take note of the battery’s orientation (+ side up) before removing it.
Step 6: Install the New CR1632 Battery
Take your new CR1632 battery and install it in the same orientation as the old one (positive side up, usually marked with a “+” symbol). Press it firmly into place until it’s securely held by the metal legs or clips.
Step 7: Reassemble the Key Fob
Place the circuit board back into its compartment within the key fob case. Snap the two halves of the key fob case back together. You might need to apply a bit of pressure to ensure they are fully closed and securely fastened.
Step 8: Test Your Key Fob
Once reassembled, test your 2007 Camry key fob to ensure it’s working correctly. Try locking and unlocking your car remotely and starting the engine (if your Camry has push-button start).
Tips for 2007 Camry Key Fob Battery Life and Replacement
- Low Battery Warning: Your 2007 Camry may display a “low key battery” warning on the dashboard. When you see this warning, it’s a good indication that you should replace the battery soon.
- Proximity to Electronics: Electronic devices can sometimes interfere with key fob battery life by causing the fob to constantly “wake up” and search for a signal. Try to store your key fob away from cell phones, laptops, and other electronic devices when possible.
- Dealer vs. DIY: Dealerships often charge a significant amount for key fob battery replacement (sometimes $50 or more). Doing it yourself with a CR1632 battery costing just a few dollars is a much more economical option.
- Emergency Start: If your key fob battery is completely dead, you can still start your 2007 Camry. Place the back of the key fob (the side with the Toyota logo) directly against the “Start” button on your dashboard. This utilizes a passive RFID chip in the key fob that doesn’t require battery power to communicate with the car for starting in emergencies.
Conclusion
Replacing the battery in your 2007 Toyota Camry key fob is a straightforward process. By knowing the correct 2007 Camry key fob battery size (CR1632) and following these simple steps, you can easily restore your key fob’s functionality and avoid unnecessary dealership costs.
