Abstract: A multi-protection touch lock has a lock body and an unlocking panel connecting to the lock body. The lock body has a control mechanism, a locking unit connecting to the control mechanism, and at least one displaying unit connecting to the control unit, and at least one connection interface connecting to the displaying unit. The at least one unlocking panel has at least one transmission interface connecting to the at least one connection interface, and at least one operating unit connecting to the at least one transmission interface. The lock can be located at the predetermined position to control the door access, vehicle actuation and the use of electrical appliances. When unlocking, the unlocking panel comes to in contact with the lock and the correct password is input via the unlocking panel. After the unlocking action is completed, the unlocking panel is removed from the predetermined position.
