If the response becomes poor, replace the battery immediately❗️Old Daihatsu car key❗️

The remote control key for my Mira Cocoa (old Daihatsu car) started to respond poorly, so I replaced the battery! The indicator light wouldn't turn on, so I decided the battery was dead!
I replaced the CR1632 battery and the electronic card key was revived!

Introducing challenges and trials for changing oil and parts in cars, and maintenance. There are many things that professionals should be able to do, such as repairing a leaking bathroom vanity, and I think that even if you try to imitate the skills of a professional, you won't be able to do them well. However, I hope that this will be helpful for you to see how far an amateur can go, as well as the various attempts made by an amateur old man.
