OK, I give up

[jpherit]

I just received my Tesla Model 3 key fob. But the darn coin batteries supplied just don't seem to fit. Slightly too large in diameter and I can't get it in place. Also, which is the correct polarity direction? Any one else have this problem? And suggestions?

Frustrated

OK, I got it. + up and then slide it under the large tab and let it snap down through the two small tabs. Thought I was going to break them but it snapped In OK.

Now try to get the battery back out.

Not the best design ...

For anyone just getting a fob, the battery lid has the direction for which side of the battery goes up. + Side facing outward towards you.
