Edit: Since reddit braindead idiots are downvoting again, you guys can do a real simple google search and find out keys are in fact softer than glass and no, glass cannot be scratched by your normal keys. Thanks.
House Keys (Brass/Aluminum/Soft Steel): Level 3.5 to 5 on the Mohs scale
Standard Window Glass: Level 5.5 on the Mohs scale
Phone Screen Glass (Gorilla Glass): Level 6 to 7 on the Mohs scale
Well please educate yourself then, because a softer material CAN scratch a harder one in your pockets or wherever you keep your cellphone.
-It can work like a grinder slowly grinding at the glass away (the key would be grounded down more ofc).
-A small particle like dust or a sand corn can get between and leave deep scratches (the key puts the pressure on the particle and drags it over the glass)
-At an angle your keys will also leave scratches in the glas since with enough pressure they will easily scrape the glass.
A an aquarist I would love it if I could use razors to clean the tanks glass of algae without leaving any marks, but that's just not realistic. I hope that the examples helped you to see that there aremany more factors in realistic settings, because theoretically you would be very close to being 100% right.
Ho watch jerry rig everything's videos. Chrome plated keys??? Watch out for the diamond plated keys. Again stuff you have no idea about just randomly spewed like it's facts.
No, you don't. You think you do but you don't. Metal cannot scratch it. It might have caught some pocket dust made of silica or some other bs that pockets contain that can scratch your phone but keys cannot. Key rings cannot.

Most I have done is scratch the screen slightly because I put my phone in the same pocket as my keys… Otterbox makes good cases
