I’ll demonstrate how to remove the battery from your Toyota 4Runner key fob and change it yourself at home in this brief lesson. It’s pretty easy to carry out. A standard flathead screwdriver and one of these CR 1632 batteries are all that are required. You might have a key fob that resembles this quite a bit, but yours is likely made of lighter gray plastic. While this one is black, the entire body is more of a light gray color.
Not to worry; it’s actually the same battery and gadget. And the process for opening it is the same. So just keep going. No matter what key you have, you simply have a different hue. Simply hold down the side button in this situation and pull the internal key out.
You can see the keyhole there from here. Following it, there is a small perpendicular indentation just across from it. See? the shape of a keyhole. To open this device, we will just twist the flathead screwdriver after inserting it into the hole.
We can now disassemble this. This rubber part should be facing up when you carefully lay it to the side. You don’t want to turn this over since your buttons might start to fall off. Simply set things aside with caution. I’ll just take the corner of my flathead screwdriver and carefully lift up this circuit board from here.
We may now leave this aside and look for the battery underneath the circuit board. Now that your circuit board is positioned exactly as shown, we should enter from the top, correct? As you can see, there is a tiny opening and a tiny corner. To prevent the battery from flying out as we get beneath it and pull it out in that manner, we’re going to insert our flathead screwdriver there and just sort of keep the battery down. You can then dispose of your old battery once it has popped out.
Take a fresh one. This is a CR 1632 battery once more. In addition, if you’re unsure where to buy one, use the link in the description to order one from Amazon. Ensure that the positive side of your battery is facing out. Therefore, you should click it in when you see this text and the battery information facing up.
Ensure that it is safe. Take a look at the small circle on the back of this plastic item. The battery will simply rest on top of that. So put that aside, grab this front piece of plastic, and let’s simply click everything back together. Okay?
