I spent 2 years looking for a BMW e46 remote service in the United States. Not one alternative to a $175 replacement key. I understood that the rechargeable battery swap would be a better alternative, so I continued to look. When Google brought up The Master Locksmith, all of the boxes were ticked: Simple, easy to suss out web site. Priced reasonably, considering the lack of competition. Easy shopping and check out. Convenient shipping process (even from the US) Ultra rapid turn around (exactly 3 weeks including shipping both ways). Truly a fantastic service. Big thanks to the entire Master Locksmith team!
