Intelligent (encoded) lock which can be opened by communication means

The invention relates to a communication tool, comprising wire and non-wire emission tools (telephone, handset and little smart), signal receiver and lock. The communication tool [1] is used to emit signals to signal receiver [2] and the signal receiver gives a signal to lock so as to take the effect of opening and closing by signal technology treatment. The merit in invention is that the communication tool is used as non-wire key, there is the encumbrance of multiple keys and it can use the lock in common with and mechanical key. The signal receiver can change itself codes in any time and the unlocking difficulty without authorized human is strengthened so that the secrecy performance is better. The signal receiver verifies if it is stored mother numbers in it to determine rejecting and receiving by signals from communication tool (mother number).
