BMW Serie 3 - Video tutorial

Model: BMW Serie 3 E91, E90, E92 - Years 2005-2013
Part: Key
Operation: How to reload the key of a BMW E90 / E91 without opening it

We know that BMW keys can be recharged using it, and we also know that it takes 30 hours to fully charge. If we leave the key in the car the key will run out if we do not use the car and this is a nuisance because the key cannot be opened and our youtuber did an experiment looking inside a BMW key and found that the battery is soldered to the CPU and therefore not replaceable. So he came up with a little thing; a sort of handcrafted battery charger, which surely someone with some knowledge of electronics will be able to replicate, in order to charge the key without placing it in the car, and in a few hours; few compared to the 30 hours it takes for normal things. It is worth a try.
