LOCK INCAPABLE OF BEING PICKED BY BLOCKING COMBINED KEY HOLE THROUGH LOCK OF REMOTE KEY

PROBLEM TO BE SOLVED: To provide a lock for blocking the key hole of a combined cylinder lock by the lock locked and unlocked by a remote key and preventing illegal unlocking by a picking tool. SOLUTION: In order to prevent illegal unlocking using the key hole, a latch type shutter for opening and blocking the key hole is attached. Normally, locking and unlocking are performed by the remote key by blocking the key hole. Thereby since the key hole is blocked, illegal locking by picking can be prevented. In an emergency, such as remote control failure, the key hole shutter is manually opened by an inside lug, and locking and unlocking can be carried out by a general cylinder lock. The start key of a vehicle has no door type, attaches a password input machine on the outside in place of the inside lug, and in the failure of the remote key a password is input after energization confirmation, and the key hole is forcibly opened electrically.
