Bought it for my 2015 Toyota Camry Fob and it worked perfect!!

When I tried to use the batteries they didn’t work but I found out that the bitter coating that they put on them has to be removed for the negative side to make contact. I used a piece of fine sand paper and the batteries work fine. Only 4 stars because there is no instructions on the packaging.

These are the best battery brands available on the market, period!

I bought a pack of 4 to replace in 2 of my key fobs. Both failed, 1 after a month, the other worked only intermittently after several months. What a disappointment considering the amount of work to replace key FOB batteries and sometimes have to reprogram.
