Way to steal Audi?
 

I left my A6 in a valet parking lot overnight (all the lots near my apartment are valet only) and the next morning I noticed all my settings were changed. The mirrors won’t auto fold when I lock and only the drivers door unlocked when I touch the handle (as opposed to all of them I had previously set).

I’m fairly sure the car showed 2 programmed key fobs in the settings and I noticed (when I was reprogramming my changed settings) that now there are showing 3 programmed keys.

Is this normal? I feel like there should be only 2, I’m not sure if the valet might’ve made a new key fob or something like that? Could someone let me know if they’ve had a similar experience? It’s a 2016 Audi A6 TDI for reference.
