the key cannot be pulled out, except the case described in 5.1.5.
4.4 The described device to prevent unauthorized use as well as parts of the vehicle that are related to their work shall be designed to make this device not unlocked immediately, inadvertently or damaged, failed with tools that are cheap, easily hidden, easily carried and manufactured by public.
4.5 The device to prevent unauthorized use as described in 4.1 shall be installed on vehicle as an original part (i.e., this device is installed by the manufacturer on the vehicle before the vehicle is first sold). It shall be installed so that -- when it is in a locked state, even in the case of its housing being removed, it cannot be dismantled without the use of special tools. If the screw is disassembled and the device to prevent unauthorized use fails, the screw shall be covered by a part secured to the device to prevent unauthorized use or with a disassembling-proof screw.
4.6 The key to the mechanical locking system shall include not less than 1000 different combinations. If less than 1,000 vehicles were built in a year, the number of combinations shall be equal to the number of vehicles. In all vehicles of one vehicle type, the occurrence of the same combination shall not exceed 1/1000.
4.7 Electric / electronic locking system (such as remote-control lock) shall have at least 50,000 kinds of changes and be incorporated into the rolling code, and/or scanning 5,000 changes shall at least require 24h.
4.8 For characteristics of device to prevent unauthorized use, 4.6 or 4.7 shall apply.
4.9 There shall not be visible codes on lock and key.
4.10 The lock shall be designed, manufactured and installed so that it shall not rotate the lock cylinder at any torque less than 2.45 N??m using any key except when equipped with the key in its locked position, and
4.10.1 For lock cylinder with pin tumbler, the tumblers that are identical, arranged in adjacent positions, working at same direction, shall not exceed two. In the same lock, the same tumblers shall not exceed 60% of total number. 4.10.2 For lock cylinder with chip tumbler, the tumblers that are identical, arranged in adjacent positions, working at same direction, shall not exceed two. In the same lock, the same tumblers shall not exceed 50% of total number. 4.11 When the vehicle is driving, the device to prevent unauthorized use shall not have any accident wrong locking as well as accident locking that may endanger the safety.
