The battery in my car key has died. Usually I can unlock the door by touching it, but I can no longer do so.If I ask a store to do this, it will cost about 1,500 yen, but if I do it myself, it will only cost 300 yen for the batteries.It only takes about 3 minutes and anyone can do it while watching Youtube.

If you do a little research and do it yourself, your living expenses will really become cheaper.It's fun and a good exercise for the mind, surprisingly.I would like to continue to enjoy doing various things on my own and save money in the future!
