jkobi: We’ll see if I eventually have the same issues as others with a faulty battery but, for now, this has completely revived the key fob on a 2010 Mini Cooper S, after months of using the ‘hidden’ key to physically lock/unlock the car (only possible from the driver’s-side door btw). No ‘relearning’ procedures were necessary—after replacing the battery, the fob worked again immediately!

The hardest part was splitting open the old case. My chrome outer ring broke off years ago so I didn’t have to remove it. Cutting the case is kinda iffy using a utility knife because the shape of the fob makes it hard to hold while cutting, so please be careful not to cut yourself! Best to take it slow and make several progressive cuts along the fob’s seam and it will eventually pry open easily.

The next-hardest part was removing the old battery—use a solder wick to remove the old solder and then carefully pry out the old battery while heating each pin, which may still be stuck due to leftover solder. Careful not to overheat the connecting circuits.

Soldering the new battery is easy—remember to clip the soldering pins when you’re done because one or both may...

Bryan wilson: It’s terrible that so much effort must go into changing a coin battery. That said, once I meticulously cut the fob in twine it was easy to desolder the old battery and solder in this new one which was an exact match for the oem one I removed. Can’t complain about the battery itself but soldering skills and basic equipment are a must in this application.

Steve Choquette: Ne fonctionne pas, les pattes de conexión doivent être à 45 degrés et non à 180 degrés comme sur ce modèle-ci

Mike Hughes: bought this for a 2007 BMW #93 328i, BMW in their wisdom made a remote that, when inserted into a slot in the dash starts the car-the remote's battery (this item) is supposed to recharge by induction while inserted into its slot. The fun part is you need to dismantle the remote, de-soder the battery from the PC board (really, is soderted into place), to replace the battery. the holder this battery come in (there are two versions, a 90 degree and a 180 degree version) is supposed to line up with the holes in the PC board, NEITHER of these lines up, I know because after buying the first one, i ordered the second, NEITHER worked so I wasted about $30 buying both, plus my time. This will not work in either configuration, and this seller needs to stop selling these as replacements for this situation.

jas0n 179: only reason for a 4 star and not 5 is that the + and - tabs were not in the same position as original, but they were close enough to make work!! glad i didnt have to buy a new key from BMW, this saved me a bundle $$$

Dwayne Kinsella: Unfortunately, the battery leads did not line up with the solder points on my BMW fob. I was able to make it work, by reusing the existing Battery bracket. Otherwise product showed up on time, and looked like the photo.

balln2k9: If you own a BMW from 2000-2003 with the "Diamond" style key (could be used in other models), you did come across the right battery. Newer BMW's (like my 2011 7-Series) use a coin style battery that can simply be replaced with a $5 investment and 3 minutes... but if you also have a 2003 BMW 530i, BMW didn't use that simple method back then.

I recently purchased a 2003 BMW 530i and noticed that the key wouldn't lock, unlock, or open the trunk when the buttons were pushed. I could insert the key into the door-lock and operate manually and also start the car. Most people have this same issue and are fine with this process, but not me. This is where the frustration started while trying to solve the key's buttons not working.

If you search BMW forms, some users will say you have a blown fuse in the trunk (BMW's ignition charges the key's battery when inserted and driving) and when replaced (and driven for many hours) your key will start working again. Other users will say "you just need to reprogram the key" as it may have lost it's memory. After weeks of looking into this issue and testing different ideas, I decided to take the risk and replace my key's...

K from NJ: The battery ran out of juices after 7 years. So this year I decided to give the battery replacement task a shot. It was time consuming to open the key, and a little tricky to solder the tabs in place. But it worked. YouTube Vids on it.

If you have a programmed key, you'll need to program both keys at the same time. Or you'll keep having one working and one not.
