Door

The Door is a simple barrier type object. You can interact with it to open it, and can be destroyed if damaged enough.

Locked Variant
A door may also be locked. There are multiple ways to get around this:
 * Destroy it (Door Detonator, fire, etc.)
 * Open it from inside
 * Use the owner's key
 * Use a Lockpick or Skeleton Key
 * Knock on the door to get the owner to open it for you
