Yep, that's what these cost these days. Not just from MB either. I know it's crazy that one of these costs as much as a smartphone, but there's no competition. For security, the factory is essentially the only one that can make the key. Has to be made specifically for your VIN, so there's an individual production process for it. They can't just pull one from the shelf and ship it like with most other parts. As demeaning as it sounds, but yes, don't lose it. Attach an AirTag to it if you are prone to losing keys. We lost one of the fobs for my wife's car. I left it on the roof of the car, because I was gonna repark her car, but then she needed to go somewhere and drove off with the key fob on the roof and it fell off somewhere. Traced where she drove, but never found it. We didn't bother replacing it. It's a fairly old car and the quote was something like $500. I attached AirTags to the remaining fob and the spare key. My wife also tends to misplace her keys, and it already paid off finding it on another occasion.
