Attach a keyhole cover

I was looking to buy a keyhole cover but the problem I had was that the keyhole on my door was already on a metal handle and any keyhole cover I could find was only designed to be screwed in.

Upon discovering Sugru I decided to apply some to a keyhole cover so that it would bond onto the metal keyhole base. For extra secureness I also applied Sugru around the rim with the remaining amount I had left.
