The remote for the S still working on the same battery after 5+ years

 

Still working fine after five years, seven months and nine days.

 

I do not know where is/are my remote(s). I did not use my remote(s) to lock/unlock my S for more than a year. Actually, I did not lock my S at work since day one and it is garaged at home, so I did not lock it at home either. I need to find my remote(s) and store it in a safe place.
