I've searched and can't find any information on replacement or original key blanks for the C5. I noticed there are some C5s for sale with no keys. I know it is probably possible to have a key made, but has anyone determined a number/ type of key that works or been able to replicate the black Sinclair rubber logo part of the key?

I think most of us just use a filing cabinet lock if there isnt a key. I imagine you could 3D print the black rubber part if you had a decent high definition 3d printer.

I had thought about doing that. I have access to some high tech 3d printers at the University I graduated from up the road from me. I know a lot of owners probably don't use their keys much if it all, but thought that might be an easy project to tackle if any owners ever wanted a replacement set of keys.
