摘要： A picklock-proof key slot for a lock device and a key thereof, which comprises a rotary cylinder and a lock casing, between which plural upper tumblers and lower tumblers are furnished; the center of the rotary cylinder is provided with a key slot; under lock up condition, the lower tumblers are pushed into the key slot; the center of the tumbler groove is furnished with a salient plate, of which both sides are furnished with symmetrical guide slots; a guide slot is furnished between the two symmetrical guide plates on the key plate; a plurality of unlock-tumbler holes is furnished on the guide slot between the two guide plates; the hole has a curved surface to fit with the curve surfaces on both sides of the lower tumbler so as to reduce the pushing-up space of the lower tumbler, and also to reduce the possibility of unlocking the lock device with a master key to push the lower tumbler.

摘要： A soft key includes a main body, a shank casing, and a shank. The main body includes a compartment defined by a pair of wall tracks. The shank casing is mounted in the main body and movable along the wall tracks between a first position in the main body and a second position out of the main body. The shank is extended through a longitudinal hole of the shank casing and the compartment of the main body. The shank includes a first end positioned in the main body and a second end, a plurality of key sections being attached to the second end of the shank in series. Each two adjacent key sections are connected by a pin, thereby allowing relative pivotal movement therebetween. Each key section includes a depression in a side thereof. An outermost key section that is most distal to the shank includes at least one slanted face.
