摘要: One or more lock key units of a secure entry system is equipped with radio receiver. The receiver permits memory in the unit to be updated new data that modulated onto frequency signal. By this technique, system-wide changes programming data, such as lockout lists and access codes, targeted specific units, disabling particular key, can implemented simply quickly.
