Is your 2007 Toyota Camry key fob not working as reliably as it used to? You might be experiencing the common frustration of a dying key fob battery. Before you rush to a dealership and spend unnecessary money, you should know that replacing the battery in your 2007 Camry key fob is a straightforward task you can easily handle yourself. This guide will walk you through each step, ensuring you can quickly and efficiently restore full functionality to your key fob.
Why Your Camry Key Fob Battery Dies (and How to Potentially Extend Its Life)
Like any battery, the one in your 2007 Camry key fob will eventually need replacing. Typically, these batteries last for a couple of years, but several factors can shorten their lifespan. Interestingly, Toyota has acknowledged this issue. According to a Toyota service bulletin, electronic devices emitting “pings” or electronic noise can cause your smart key to “wake up” unnecessarily, leading to quicker battery depletion.
Common culprits include:
- Cell phones
- Laptops and desktop computers
- TVs and monitors
- Cordless phones
- DVD and VCR units
To maximize the life of your 2007 Camry Key Fob Battery, try to store your keys at least 40 inches (1 meter) away from these devices when you are at home or work. While completely separating your key fob from your phone might be impractical when you are out and about, being mindful of storage at home can make a difference.
What You’ll Need for the Replacement
Fortunately, replacing the battery in your 2007 Camry key fob requires minimal tools. Here’s what you’ll need:
- Your 2007 Camry Smart Key Fob: This is a given!
- A New CR1632 Battery: This is the specific type of battery required for your key fob. You can find these at most drug stores, electronics stores like Radio Shack or Batteries Plus, and online retailers.
- The Mechanical Key from Your Fob: This key is cleverly hidden within your smart key fob and serves as the primary tool for opening the casing.
Step-by-Step Guide to Replacing Your 2007 Camry Key Fob Battery
Follow these simple steps to replace the battery in your 2007 Camry key fob:
Step 1: Remove the Mechanical Key
Locate the small latch on the side of your key fob. Press and hold this latch while gently pulling out the mechanical key. This key is designed to be easily removed and is essential for the next step.
Step 2: Open the Key Fob Casing
Now, look for a narrow slot on the key fob, positioned perpendicular to where you just removed the mechanical key. Insert the thinned end of the mechanical key into this slot. Gently twist the mechanical key. This twisting motion will apply leverage and pop open the key fob casing. You might hear a slight clicking sound as the two halves separate.
Step 3: Access the Circuit Board and Battery
Once the casing is open, you’ll see the internal circuit board. The battery is located on the underside of this board. The circuit board is held in place with a mild adhesive, so it won’t simply fall out. Carefully slide the end of the mechanical key underneath the circuit board and gently lever it upwards. This will detach the board from the casing, giving you access to the battery.
Step 4: Replace the CR1632 Battery
The CR1632 battery is held in place by small metal legs or clips. Carefully use your fingertip or the tip of the mechanical key to gently spring these legs open one at a time. This will release the old battery. Remove the old battery and insert the new CR1632 battery. Ensure the positive (+) side of the battery is facing upwards, as indicated by the markings in the battery compartment.
Step 5: Reassemble the Key Fob
With the new battery in place, carefully put the circuit board back into its compartment within the key fob casing. 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 securely closed. Finally, slide the mechanical key back into its slot until it clicks into place.
Tips and Troubleshooting
- Low Battery Warning: If your 2007 Camry’s dashboard display has been showing a “low key battery” warning, it’s wise to replace the battery soon as it is likely to fail completely in the near future.
- Car Won’t Start After Battery Replacement? In rare cases, even with a new battery, your car might not immediately recognize the key fob. If this happens, Toyota recommends placing the back of the key fob (the side with the Toyota logo) directly against the “Start” button on your dashboard. This often provides enough of a signal to start the car.
- Where to Buy CR1632 Batteries: As mentioned, CR1632 batteries are readily available. Check drug stores, electronics retailers like Radio Shack or Batteries Plus, and online marketplaces for the best prices.
- Dealer Costs: Dealerships often charge a significant amount for this simple service, sometimes upwards of $50! By following these steps, you can save yourself a considerable sum and gain the satisfaction of DIY car maintenance.
Replacing your 2007 Camry key fob battery is an easy and cost-effective way to maintain your vehicle. With a fresh battery, you can expect your key fob to function reliably for years to come.
