Hi guys, in this video I show the step by step procedure on how I replaced the weak battery of my Toyota Rush wireless key fob. It is using a 3-volt Lithium 2032 battery. Mine lasted for about 2 years before the performance became irregular. This procedure was taken straight from pages 284- 285 of the car's owners manual. I think the Toyota Wigo has a similar key fob but to be sure, if you have another Toyota car model, I suggest you refer to your owner's manual for instructions, as their battery might not be the same. I would appreciate your support by a thumbs up and subscribing. Thank you and have a nice day!
