Lock devices, systems and methods

An apparatus, comprising:

• a housing having an inner bolt housing and a cam housing, the cam housing being telescopically coupled to the inner bolt housing, the cam housing including a first housing feature;
• a bolt having an aperture, a portion of the bolt positioned within the inner bolt housing;
• a cam having an extension, a first cam feature, and an aperture, the aperture sized for receipt of a complementary shaped driver;
• and
• wherein the first housing feature and the cam first feature are configured to prohibit the cam from being rotably coupled to the cam housing at more than a single orientation relative to the cam housing, and wherein the extension is engaged with the aperture of the bolt when the cam is rotably coupled to the cam housing at the single orientation.

A method, comprising:

• moving a door bolt cam and a door bolt housing into a pre-installation orientation;
• manipulating a relative orientation of the door bolt cam and the door bolt housing to align:
• a first cam feature of the door bolt cam with respect to a first housing feature the door bolt housing, and
• a second cam feature of the door bolt cam with respect to a second housing feature the door bolt housing, the second cam feature having a configuration that prevents alignment of the second cam with the first housing feature;
• wherein the manipulating results in only one possible orientation of the door bolt cam relative to the door bolt housing;
• and
• as a result of the manipulating, inserting the door bolt cam into the door bolt housing such that the door bolt cam is installed into the door bolt housing in one orientation.
