Keyslink Auto

Keyslink Auto is a spring loaded version of my original Keyslink. The key fires out from the front when the button is pressed and is retracted manually. You will need some springs which you can get in a small kit or individually or from other devices, as well as a couple of machine screws and nuts.The key modification is the same from the previous keyslink version, only the back is ground to be more flush with the height of the key (you can tweak it accordingly to fit into the carriage).
