Claim:
A bollard assembly, comprising: a post comprising a generally cylindrical post wall forming a cavity, the post wall having a passage comprising a first section extending generally longitudinally along the post wall and a second section intersecting the first section and extending generally crosswise to the first section; a sleeve comprising a generally cylindrical sleeve wall forming a cavity and a latch pin attached to the sleeve wall and extending into the cavity, wherein the sleeve is adapted to receive the post such that the latch pin travels through the passage in the post wall; and a lock assembly comprising a lock cylinder secured to the post wall and extending into the post cavity and a bar connected to the lock cylinder and disposed within the cavity formed by the post wall such that the bar prevents the latch pin from traveling through the passage with the lock cylinder in a first position and allows the latch pin to travel through the passage with the lock cylinder in a second position, wherein the bar prevents the latch pin from traveling through the passage by blocking a section of the passage.
