Toyota Key Battery
My was having some trouble with his Toyota remote and actually thought it would need to be replaced. So rather than leave him to spend what’s likely a lot of money, we went ahead and opened it up. We did a video as well that you can see here.
There is a gap upper corner that is your way in. A small screwdriver will do the trick.
Note right away that the buttons are loose and keeping the button side down would be helpful. Also, the buttons only fit in one spot each, so not to worry.
The battery is found in a case inside the key and it too needs to be separated. Check out the video for instructions and have a CR 2016 battery on hand. There is a circuit board inside that is loose and also goes in just one way.

Smart Keys or Intelligent Keys, or Access Keys – or whatever the manufacturer of your chooses to call them – that let you into your car and start it with just a touch use up their internal batteries at alarming rates, catching busy drivers unawares – even though the car had tried to warn you.
Our goal is to help you feel safe – and keep you moving or get you moving if at all possible – rather than leave you fretting whenever your key fob stops working. The instructions for getting into and starting most keyless start cars can be found on our pages – without roadside assistance.
