It would not be normal for the chuck key to be sprung. The socket in the chuck is normally sprung to eject a key when it is not positively pressed in.

There is an EN standard for lathe chucks BS EN1550:1997 +A1:2008 Machine-tools safety - Safety requirements for the design and construction of work holding chucks

New chucks supplied separately or as part of a complete lathe are subject to the Machinery Directive 2006/42/EC and should aim to meet this standard.
