I’ll walk you through the process of disassembling your Toyota RAV4 key fob so you can replace the internal battery at home in this brief lesson. You’ll need one of these CR 2025 batteries, but it’s a really simple procedure. Now, if you’re unsure of where to find one of those or would just like to buy one online. I’ll include a link in the description so you may purchase one from Amazon for just a few dollars. So go ahead and look that up so we can get started right away.
Therefore, the first step is to gaze up at the device’s top. Along the seam, there is a little slot in the plastic. We’re going to take a standard flathead screwdriver, place it there, and then just start twisting the screwdriver to open this thing up. Now that the plastic back portion is set aside, you can look over here at the battery, which is located directly above and to the upper right. The top right side of the device, if you were to turn it about, would have that tiny hole or opening in the plastic.
As you observed, you can actually pry out the battery using the corner of a flathead screwdriver of standard size. Therefore, you sort of shove the battery down and glue it down before raising it up. And it’s really not that difficult. It’s actually lot simpler to just get inside with anything like a tiny precision screwdriver or even a paper clip. However, you shouldn’t have any issues using a simple instrument that you already have at home.
Take your CR 2025 batteries out, then go buy a new one. Make sure to reinstall it with the positive side facing out. To ensure that the plus side is facing up, simply slide it in, slide that down, and then click on the top. Now all that has to be done is to click the device’s two pieces back together, check that the light turns on, and you’ll be ready to go. I sincerely hope that was useful to you; if it was, please let me know in the comments section below or just by giving this video a like so that others can find it and benefit from it as well.
