Although not one to disagree with anything Muttley says, it takes a single CR2032 or two CR2016's
Thank you, I think. Flapper's
guide showed two batteries, and I didn't want to take my key apart unnecessarily. My mistake - just done so, and my standard key contains a single CR2032.
I have to say though that 2xCR2016 are NOT the same as 1x2032. Yes, they will fit in the same space, but two batteries in series will deliver 6V, which is likely to upset electronics expecting 3V.
