Speaking of which there are some croocked locksmiths out there who pretend they cant lockpick the lock, try a few different methods to fail and add to labor and eventually drill through the core, damage the lock, charge you more than 500 and additional few hundred to replace the lock. It happened to my friend’s mom. Sometimes it’s experience but sometimes it’s just overcharging. If it’s higher than market price it may overcharging or better quality
