Works perfectly when switching out.

This was quite easy to replace with instructions

Batteries were as described and worked with the key fob.

Super

I felt like my key fob was getting a little slow so I was thrilled to see this pop up in vine. As simple as it was to replace the battery, I did watch the recommended video. I only have one key fob and wanted to make sure I did the replacement correctly. Very easy process for a first time battery replacement.

I bought so many different brands of batteries even the big name ones to replace my Mercedes key fobs batteries. Every one would work for a time or two then the message would come up in my car that the battery needed to be replaced again. I was getting frustrated that none would last longer than a few days without the message popping up so I got these and I finally got batteries that have been in for months now and I get no message! These truly are the only ones that seem to work for me so if you have the same issue give these a try! Will get more!

This item is packaged specifically for using as a key fob, but can be used with any item requiring a like sized coin battery.I recommend writing the date, using a Sharpie, on the battery when you install it so you can determine if it lasted a reasonable amount of time. If it does not last, you can then shop other brands.

All items included work perf to get the job done but lil screw driver broke after installing.
