Hi Viewers and fellow youtubers. Today i have brought another video for you all in which i will show you how to change the battery of a toyota prius and aqua This is an easy procedure And you will not require any kind of tool for this. Let’s begin Here is the keyless remote you need to open safely without cracking the top cover. First step is to locate a button which says push. Push the top end of that button to release the emergency car key provided. Once your spare key is out. Use it to pry open the cover gently by placing the key in the slot below the key housing. Give it a gentle twist clockwise to pry the key lid open. Pick up the circuit board gently to reveal the battery below. Replace with a 3 VOLT CR1632 battery only. After the battery is replaced. close the cover and test the key buttons. I hope this video was useful. Please SUBSCRIBE and Like the video.
