Multi-unit access control and information management system

A locking mechanism comprising:

• a captive latch pin protruding from a slidable member,
• wherein the slidable member comprises a tongue coupled to the captive latch pin,
• wherein the tongue comprises a first portion that is coupled to a second portion that comprises the captive latch pin, wherein the first portion and the second portion are selectively slidable such that a longitudinal dimension of a combination of the first portion and the second portion is variable;
• an actuator assembly including a captive latch and an actuator configured to manipulate the captive latch between a first orientation configured to selectively retain the captive latch pin and a second orientation configured not to selectively retain the captive latch pin;
• and
• a lock body obstructing access to at least a portion of the slidable member and the actuator assembly.
