I never use WD 40 for this,
it is in fact an oil which dries out and causes more sticking problems in the long run.
What I use with good results is Graphite powder.
Which is basically ground down pencil lead,
which if you didn't know is amazingly slippy stuff and doesn't dry out.
Use the nozzle to puff as much as you want into the mechanism and work the catch back and forth.
Sure Ebay sells it.
The only thing I'd use inside locks.
