Replacing the battery in your 2007 Prius key fob is a straightforward process. This guide will walk you through each step, ensuring you can get your key fob back in perfect working order in no time. Typically, the original batteries in these fobs, often Panasonic, last for 3 to 5 years. Let’s get started and show you how to replace your Battery For 2007 Prius Key Fob.
Tools You’ll Need
Before you begin, gather these simple tools:
- Precision Philips head screwdriver: A #0 size is ideal.
- Small flat-head screwdriver or paperclip: For prying and separating components.
Parts Required
- CR2032 Battery: You’ll need one CR2032 battery. This is a widely available and inexpensive coin cell battery. Make sure to have a fresh CR2032 battery ready before you start.
Step-by-Step Battery Replacement
Follow these simple steps to replace the battery for your 2007 Prius key fob:
Step 1: Remove the Emergency Key
With the buttons facing upwards, locate the small spring-loaded latch on the side of your key fob. Slide this latch to the left (usually indicated in red) and simultaneously pull the emergency key upwards and out of the fob. This removes the emergency key and gives you access to the fob casing.
Step 2: Open the Key Fob Casing
Flip the key fob over so the buttons are facing down. Again, locate the spring-loaded holder, this time slide it to the right (usually indicated in red). While holding it to the right, push the back panel of the fob upwards (as indicated in blue in the image). The back panel should slide off. If you encounter resistance, try using a rubber glove to improve your grip on the fob for better leverage when sliding the panel. This action opens the key fob casing to reveal the internal components.
Step 3: Access the Battery Compartment
With the back cover removed, you’ll see four small screws. Use your Philips #0 screwdriver to remove these screws, which are circled in red in the image. Once the screws are out, you’ll see a battery cover plate. Use a paperclip or a thin flat-head screwdriver to gently pry up this cover plate at the location indicated by the blue arrow in the image. This will access the battery compartment where the CR2032 battery is located.
Step 4: Replace the Old Battery
Now you can remove the old CR2032 battery. Take note of the orientation – the positive (+) side should be facing upwards, towards the cover panel. Insert the new CR2032 battery in the same orientation, ensuring the positive (+) side is facing up. With the new CR2032 battery replacement in place, reassembly is simply the reverse of these steps. Replace the battery cover plate, tighten the four screws, slide the back panel back into place until it clicks, and finally, re-insert the emergency key.
Conclusion
Congratulations! You’ve successfully replaced the battery for your 2007 Prius key fob. This simple maintenance task will ensure your key fob continues to function reliably. By following these steps, you’ve saved yourself time and potentially money by avoiding a trip to the dealership. Keep in mind that key fob batteries typically last for several years, but knowing how to replace them yourself is a valuable skill for any 2007 Prius owner.
