M-Pass flat battery

My M-Pass unit is barely 2 years old and has stopped working. One of the guys at a toll reckoned I have a flat battery.

 

Do you prize it open and change the battery yourself or do you have to get a new one?

My M-Pass battery conked out 6 months ago.  I assumed a battery change would fix it.  Missus advises me that battery cannot be changed and she took the device to wherever she originally got it and was issued with a new device.

Yeah, I guessed so.

 

I found a YT video showing a guy opening one up and the battery looks like one of those coin cell stacks that they make in you-know-where. I'm kind of worried about having it in my car now!
