A system for authorizing access to a secured location, such as the vault of an automated teller machine (ATM) or the coin box of a pay telephone, without a key or combination for the secured location, and without requiring a fixed communication link extending to the location. A service technician receives an encoded access message which identifies a present access code previously stored at the secured location, the personal identification number (PIN) of the technician, and the identification number of a portable terminal assigned to that technician. The technician manually enters the encoded access message and the proper PIN into the terminal, where the identification number stored in the terminal and the manually- entered PIN are verified against the information encoded in the access message. If that information is authenticated, the technician then proceeds to the secured location and connects the portable terminal to a processor at that location. The encoded access message is transferred from the terminal to the secured location, where the access code previously stored at that location is compared with information contained in the encoded access message. The technician must also re-enter the proper PIN at this time. Access is granted only if all information is verified by information in the encoded access message. If access is allowed, the access code at the secured location is replaced by a new access code contained in the encoded access message, and that new access code is stored for the next authorized access to the particular secured location.
