Abstract
A lock apparatus generally includes a connecting portion, a housing, a primary lock, and a secondary lock. The connecting portion is engageable to the housing with a bolt assembly, and the primary lock locks the bolt assembly in the engaged position. The secondary lock arrests the bolt assembly in the engaged and locked condition in response to an attack that displaces the primary lock from a nominal configuration.
