Thanks for the response, Andrew.

I tried to replace the battery on that one and it didn't work. My soldering skills aren't the best though.

About six years ago, I got a complete cut key and one uncut one from China something like $30 each. I programmed the remote function, but they have yet to be paired with EWS. I bought the cheapo programming box back then too, but haven't used it since one of the original keys is still soldiering on
