A vending machine uses a field-programmable electronic lock that learns a key code from a corresponding electronic key, a hand-held program unit, or an external computing device via wireless communications. In one mode, the electronic lock has a learning process activation device that is accessible only when the door of the vending machine is in the open position. In another mode, the electronic lock is programmed in the field without first opening the vending machine. A program command and access control data including a new access code are transmitted wirelessly from a hand-held program unit or the like. Alternatively, an external computing device is used to program the electronic lock via long-range wireless communications, and an electronic key is then used to open the electronic lock to physically access the vending machine.

The access control system of claim 1 whereby the lock utilizes a first decryption algorithm to decrypt the first encrypted message and utilizes a second decryption algorithm to decrypt the second encrypted message. 18. A method of programming an electronic lock memory installed in a secured enclosure, comprising: receiving, by the electronic lock while the enclosure door is open, a signal activated by an enabler operatively connected to the lock to trigger the lock to enter into a code program operation; receiving, by the electronic lock, a first encrypted message comprising a first code transmitted by a device external to the electronic lock; receiving, by the electronic lock, the first encrypted message and obtaining the first code; storing by the electronic lock, the obtained first code into the electronic lock memory. 19. The method of claim 18 further including the step of transferring, by an electronic key to the electronic lock, a second encrypted message comprising a second code, and unlocking, by the electronic lock, a door of the enclosure if the second code received from a the electronic key matches the first code stored in the lock memory. 20. The method of claim 18 further including the step of the lock encrypting a second code and transferring the second code from the lock to a device external to the lock as a second encrypted message. 21. The method of claim 19 further including the step of the lock encrypting a third code and transferring the third code from the lock to the key as a third encrypted message. 22. The method of claim 20 whereby the second code is a lock identification number. 23. The method of claim 21 whereby the third code is a lock identification number. 24. The method of claim 19 further including the step of the key transferring a key identification number and the time and/or date to the lock to for storing in a memory to forming one of a plurality of access event records. 25.
