A locking mechanism to secure a coin operated vending machine includes an elongate locking bar insertable into a housing of the vending machine to secure closed a door hingedly mounted to the housing. A pair of metal loops integral with the door, and a pair of cover plates integral with the housing, are aligned to simultaneously contain the locking bar when the door is closed. A key-operated lock cylinder, mounted in recessed fashion inside the housing, supports a latch for pivotal movement toward and away from a latching position, wherein the latch enters a slot formed in the locking bar to keep the locking bar in its locking position. A reinforcing plate, with a keyway and a larger opening to permit insertion of the locking bar, protects the locking mechanism against tampering to discourage unauthorized entry into the vending machine.
