Yale 500 Series
Recently a I got a pin tumbler Yale lock which is from a new series “500”. Yale locks, though sometimes can be a pig to pick but most of the time will pick relatively easy
Or so I thought.
The key didn’t seems to have a very special bitting so I started picking and after 15 mints moved to the HPG and bumping and since that didn’t work either and I decided to see what’s inside.
They were 4 nasty mushroom pins and an anti drill one. Those pins are very similar to the Corbin ones.
The inside pins holes have carves insdie.
The pins will drop very low into the plug which is unusal as they don’t normaly do that.
All in all it looks like a very good lock and it is very hard to pick.
