It fitted perfectly in the holes at 90 degrees to each other vacated by the old battery. I found that it was tricky to split the fob neatly and is probably is no longer able to accept a further replacement battery. Having done all that, it now appears after confirming that the voltage is being applied correctly, that the fob circuit itself is defective.

I got this battery to fit in a BMW E46 Diamond key. The legs on this battery don't quite line up for that but I was able to remove the positive side leg and reuse the original cage from the remote. Then it was just a matter of soldering in the new negative side leg and gluing on the original cage. You can find these batteries with legs that line up exactly if you're willing to wait for a delivery from Hong Kong, but for the price and speed of delivery this was the best choice for me. Worked perfectly.

Battery fitted my BMW 3 series key fob (sealed type). Easy to de-solder old battery and fit new one. Battery was pre-charged, so it worked straight away. Hardest part was nothing to do with the battery, but splitting the key fob apart to get to the circuit board. It also arrived quickly by mail.

Excellent product, the battery came caged in its mount and I soldered it into the PCB. It already had some charge and worked first time, many thanks. Just got to stop the wife from putting the key in the washing machine!!
