The 140s reduced pin-tumbler count and poor manufacturing tolerances allows it to be easily picked by low skill attackers despite having spool pins. It is commonly used in [[locksport]] groups and an introductory lock for beginners to learn about defeating security pins. The No. 140 may be vulnerable to one or more of the following:

* [[Lockpicking]]
* [[Key bumping]]
* [[Impressioning]]
* [[Bypass]]
* [[Destructive entry]]
