Update!!!During the coldest months of the winter the battery started working and has been working ever since! So these are the best batteries once they started to work!Put the new battery in my key fob and tried it out and it worked. Used it a few times that day but it hasn’t worked very well since! Once in a blue moon it will actually work!I thought being a Duracell battery that it would work better but it’s not!It doesn’t hold the power and it was a waste of money. It fit my key fob and was the correct number and size.

Great battery used with ECG.

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.

Get this for your car's keyless start/lock fob; one for the main and spare fob, one for the glovebox, and one for the "junk" drawer. This setup has helped me and some friends out numerous times by having spares readily accessible.

Is this a joke? Can’t even turn on the small key fob light. There’s zero power on the tester. This is made in China and the one from my key is made in Japan.

Great battery for great price. Do your research.
