What do you think?

It’s a very simple and easy task. Battery life-span, for example, Hiace is said to be 1-2 years.

The following are often cited as reasons for shortening the life-span. “The area where the key is placed is bad” It is said that places with a lot of radio waves shorten the life-span.

Specifically, you need to be careful near the TV or microwave oven. Immediately change the place to put. Also, since the smart key corresponds with the car using radio waves, even if you are away from the car, if the same radio wave is around, the smart key tries to check if it is a car.

The smart key will continue to emit radio waves for the verification process until the end of life-span. Even if you are not using the key. This is one of the causes for the battery to be exhausted quickly.
