Synology NAS Replacement Key & Numberplate

These are replacement keys for Synology NAS like DS918 or any other with 3,5" Hard disks with a Key lock.
I use this in my private environment because there is no extra safety needed (These locks aren't safe anyway).
It's also nice to have a number on the bays in case you remove them and forget the correct order (very important for Raid configuration)
You can simply twist the keys to unlock. When the numbers are twisted upside , then the bay is locked.

Update: Added a version with a slightly thicker "Pin" (marked mit +0,2mm) that might fit better for you.

Update: Added 2 "Numberfree" Keys in both sizes (Called KeyZero)
