How to change the battery in non-removable BMW keys

Model: BMW BMW Various
Part: Key

In this video, we are taught how to change the battery in those BMW key fobs that do not allow for the battery to be easily replaced. Unfortunately, for these key fobs, the entire key fob would need to be replaced, costing between 300 and 350 euros. However, it is possible, with patience, to dismantle the key fob and simply change the battery, which costs only a few euros. We need to insert a pointed object into the small hole on the bottom side of the key fob, and then carefully pry apart the two sides, using something pointed to help. Once we have separated the two halves, as the YouTuber suggests, it is not necessary to also pry apart the small pieces like he did, as we will need to glue them back together later; just separate it in two. The battery is also glued in place, and it will require careful attention to remove it from its housing, but once done, when regluing everything back together, be light with the amount of glue; if we have to do it again, we do not want to go through all that effort.
