Abstract: PROBLEM TO BE SOLVED: To provide a wireless control type keyless lock system to unlock the front and rear wheels of a locked bicycle from a a several meter distant place. SOLUTION: An electric wave of a constant level containing an ID code is emitted from the transmission side. A receiving module 11 of a keyless lock 20 receives the electric wave, and the base current of a transistor flows from a module 11 to a power source 12 for starting, the power source 12 for starting is started, and a power is fed to the receiving module 11 for a given time to start receiving operation. The receiving module 11 modulates a receiving current to a DC pulse signal and an ID code is fetched, and collation is effected by a control part. When the codes coincide with each other, a power is fed to a drive part 8 so that an electromagnetic type release valve 7 performs unlock operation. The drive part 8 is operated for a given time and a stopper part 9 a of solenoid-operated release valve 7 is moved for a given time.  Since a stopper part 9 hooked by a protrusion part 3 of a lock lever 1 is dislocated, the lock bar 1 is moved in the direction of an end part 2 through the restoring force of a spring 6 and the keyless lock 20 is unlocked.
