       5.4. The protective device referred to in paragraph 5.1. above, and the vehicle components on which it operates, shall be so designed that it cannot rapidly and without attracting attention, be opened, rendered ineffective, or destroyed by, for example, the use of low-cost, easily-concealed tools, equipment or fabrications readily available to the public at large.

       5.5. The protective device shall be mounted on the vehicle as an item of original equipment, i.e. equipment installed by the vehicle manufacturer prior to first retail sale. It shall be fitted in such a way that even after removal of its housing it cannot, when in the blocked condition, be dismantled otherwise than with special tools. If it would be possible to render the protective device ineffective by the removal of screws, the screws shall, unless they are non-removable screws, be covered by parts of the blocked protective device.

       5.6. The key locking system shall provide at least 1,000 different key combinations or a number equal to the total number of vehicles manufactured annually if less than 1,000. In vehicles of one type the frequency of occurrence of each combination shall be roughly one per 1,000.

       5.7. The key and lock shall not be visibly coded.

       5.8. The lock shall be so designed, constructed and fitted that turning of the lock cylinder, when in the locked position, with a torque of less than 0.245 mdaN is not possible with anything other than the mating key, and

       5.8.1 for lock cylinders with pin tumblers no more than two identical tumblers operating in the same direction shall be positioned adjacent to each other, and in a lock there shall not be more than 60 per cent identical tumblers,

       5.8.2. for lock cylinders with disc tumblers no more than two identical tumblers operating in the same direction shall be positioned adjacent to each other, and in a lock there shall not be more than 50 per cent identical tumblers.

       5.9. Protective devices shall be such as to exclude any risk, while the vehicle is in motion, of accidental blockage likely to compromise safety in particular.

       5.9.1. It shall not be possible to activate protective devices acting on the steering, transmission or gear shift control without first setting the engine controls to a stop condition and then performing an action which is not an uninterrupted continuation of stopping the engine.

       5.9.2. In the case of devices acting on the steering, transmission or gear shift control, if the action of key withdrawal activates the device it shall either necessitate a minimum movement of 2 mm before activation of the device or incorporate an override facility to prevent accidental removal or partial withdrawal of the key.
