For picking the Everest lock you have to have an additional tool to go along with your normal picking methods.
On the Everest Cylinders there is a small pin in the cylinder that goes down in the
bottom of the plug,
So to get around this you just make a small bypass tool out of thin flat steel 2mm wide and about an inch long. file the end to a bevel.
Just insert the tool in the small slit in the bottom of the key-way and it lifts the pin
so the lock can be picked in the normal fashion.
