My key FOB has been dying out on me every week.

I've went through like 5 batteries already because I hate having to manually unlock my car .

Every time I put a new battery in I have to reprogram it as well, though, it's very easy to do.

I tested each brand new and when shot and I could tell a reasonable difference in the voltages.

I believe it's the battery that I'm using or the moisture around me getting through my pant pocket onto the battery which fries it.

Any suggestions will be appreciated. Thanks!
