A lock enhancement arrangement for protecting a cylinder lock, from being damaged by an axial tension is disclosed. The lock enhancement arrangement comprises a lock body having a lock channel defining an axial lock cavity and an axial reinforcing cavity, a lock unit which is adapted for actuating a latch assembly, comprising a lock cylinder disposed in the lock cavity for a corresponding key to actuate the latch assembly and a pin seat radially extended from the lock cylinder at a position within the reinforcing cavity, and a retention member, having an axial retaining slot, securely supported within the reinforcing cavity, wherein the pin seat of the lock unit is substantially engaged with the retaining slot of the retention member to block an axial movement of the lock cylinder within the lock cavity so as to substantially retain the lock unit within the lock channel of the lock body.
