ABSTRACT:
A security system for protecting a protected device including control circuitry, a non-volatile memory, a data transceiver, and input keys. A remote activation unit, including a non-volatile memory, data transceiver, and input key, is used to access the protected unit by communicating a code stored in the memory of the activation unit to the protected unit via data transceivers. If the activation unit is lost or the user desires to change the password, the user may enter a new password using the input keys of the protected unit, which is then stored in the non-volatile memory of the protected unit. The user may then initiate a password programming operation, which would involve the communication of the new password entered by the user to the remote activation unit via the data transceivers. Once the remote activation unit receives the new password, it would then store the new password in the non-volatile memory of the activation unit.
