Unable to unlock even from 3 meters ...

I am riding the new Sienta HYBRID G White Pearl.

Since we are doing various things, such as turning the blinker to LED or attaching a sequential blinker, When returning to Sienta parked in the parking lot, unlock it with a smart key from a little distance, I'm really looking forward to seeing Sienta's “light” ( ̄∀ ̄)

I used to feel unlocked from a distance of about 20 meters, Recently, I could not unlock unless I was close to some extent.
That's what it was ...
I had a little miserable thought, but the other day I had to get close to Sienta about 3 meters, Could not unlock.

“Ah, is that so, the battery of the smart key has run out (・ □ ・;)”

I finally realized (^ _ ^;)
Certainly, it ’s been two years since Sienta came soon, so it ’s not a strange time to run out of batteries. If you change the battery, you can unlock it from a distance as before! (* ^ ▽ ^ *)

The button battery is CR2032.

Let's open Sienta's smart key immediately.
In Sienta's manual, I only wrote it smoothly, but I think it will be somehow.


↓First, press the button for taking out the (physical) key on the left side of the smart key, Remove the key.
This key is used when the battery of the smart key has run out, When the battery of Sienta has run out It is a key to insert into the keyhole in the door knob of the driver's seat.
I think many people never use it.


↓When the (physical) key is removed, it looks like this. It seems to be good to put a flathead screwdriver in the hole on the left side of this photo and twist it.


↓Insert a flathead screwdriver and twist a little ... It did not stop with screws.


↓This is open. If you open it, you can see the contents. I just opened it to replace the battery (^ ◇ ^;)
With Polo Polo, there was no such thing as removing small parts.


↓From the crack on the right side of the photo above, I took out the contents and finally saw the battery like this!


↓The button battery that was attached was Panasonic's “CR2032”.


Watch out for Amazon button batteries

Speaking of which, there was CR2032 that I bought in amazon before! You don't have to buy it! Lucky (^_^)
I thought ... This cheap button battery I bought amazon a few years ago was unopened. After all, the battery was dead and I couldn't use it ... (◎ _ ◎;)

Looking at reviews on Amazon's button batteries, it seems that those that are nearing the expiration date are often sold cheaply. I seemed to have bought it and couldn't use it anymore. If you plan to buy it and use it right away, there will be no problem. Even if you buy too many, if you leave them for a long time, they will become unusable ...
Be careful when buying cheap button batteries on amazon!


After all, I went to a nearby home center and bought Panasonic's “CR2032”.

↓As shown in this photo, the expiration date was until November of 2022. This is safe (^_^)


Now that installation is complete, it ’s OK even 20 meters away!

Take care and remove the attached battery with your fingers. I twisted it off. In particular, it took off smoothly without any waste.


↓When you remove the button, it looks like this. As expected, the smart key has only high parts, Unlike how to attach toy button batteries, it is a solid creation.


↓Insert a new button battery there (this picture is a bad old battery). Installation was usually done with fingers.


↓After that, just install the smart key as it was and you're done! It is an impression that it took a lot of work for a screw not there (^ _ ^;)


↓A leather case is also included, and now you can lock and unlock comfortably without having to replace batteries! (^ ^)

In fact, I tried to unlock about 20 meters away, but I was able to unlock it! (T ^ T)
This feeling! When the battery runs out, the distance you can react to becomes smaller. I thought that when the battery would run out, it would disappear more quickly. But over many months, the distance over which radio waves reach slowly decreases.

Please pay attention to the expiration date when purchasing a button battery (^_^)
