My two cents is to go OE from bmwmini parts, if able. Getting locked out, either physically or via the EWS due to a crappy overseas key was high on my list of old car worries. I agree, the OE BMW key is worth the peace of mind.

As Andrewwyn said, no scanner or other tool needed to pair it. Follow the directions that come with the key, and watch a YouTube video or two before doing it. Nothing cosmic to it, but a definite order to follow. The new key goes first and becomes the master, then I did my two original old keys as backups.
