Foreign manufacturers of all kinds of locking devices often forget about the features of our climate and ignore the professionalism of Russian crooks.

It’s understandable - it’s hard to invent skis without knowing the snow. So it turns out that there are a lot of locks on sale, but the good of them … This one freezes in the cold, another one is opened with any screwdriver, the third one is pulled by the cable sheath, the fourth one has a huge backlash, and the fifth one cannot be opened, including the owner …
The Moscow company CONTEH knows about Russian problems firsthand - registration is obligatory. The solution method patented by the company’s specialists is embodied in Defen.time devices.
Let's get acquainted with the first of them - the engine compartment lock. There are two main parts of this device - a locking mechanism and an electric drive (photo above). In the locking mechanism - a metal pin (Fig. 1), the movement of which is controlled by a cable controlled by an electric drive. The enclosed structure has an anticorrosive galvanic coating and does not require maintenance.
The peculiarity of the castle is that both its positions - open and closed - are fixed. This solution is acceptable for several reasons. Firstly, the owner of the car, once having turned off the security, can then calmly open the hood, using only the regular mechanism. The same applies to preventive maintenance work - there is no need to familiarize local locksmiths with the algorithm for penetrating the engine compartment. Secondly, if security is enabled, then access to the motor will remain closed to crooks even with the complete destruction of all control electronics. Finally, such a lock consumes energy only when switching from one state to another. By the way, a special coupling for transmitting the torque from the electric motor to the drive of the locking device prevents the mechanism from jamming in the event of electrical equipment malfunctions.
Interestingly, the proposed design of the locking mechanism does not require parallelism of the fixing planes (Fig. 2). His hook (photo 1) is attached in several ways - with a bracket, “directly”, etc. Thanks to this, Defen.time can be installed on almost any car. Note that even with deformation of the bonnet or front panel, the lock will not lose its operability (Fig. 3).
But what if something “dies”? For this unpleasant case, a locking cable is provided, connected to the electric drive mechanism. When installing the lock on a car, the cable is securely hidden in an inaccessible place and shown to the owner how to reach it. As a rule, for this you have to climb into the wheel arch or under the car.
The “unopened” hood allows you to use the simplest ways to electrically lock the engine start-up circuits - neither direct “short-circuits” nor “spiders” are terrible in this case. The switching contact group located inside the electric drive is capable of switching current up to 4 A - it can be connected to a vital circuit at the discretion of the owner of the machine. If the indicated current is not enough, then apply a relay. In any case, to start the engine, you must first unlock the hood.
It is simple to control the lock - just apply a voltage pulse of the required polarity to the electric drive. Any self-respecting alarm system can do this.
It is unreasonable to use antediluvian toggle switch instead of modern electronics - a thief who has penetrated the interior will instantly “calculate” it. However, it is not only a thief. KONTECH recommends comprehensive protection for the car, installing its locks not only on the hoods, but also on the door! And if so, then you still can not do without remote control - otherwise you can’t get into the car. Therefore, in any case, the toggle switch will be out of work.
The door lock (photo 2) differs from the engine compartment by the locking mechanism - its metal pin, when locked, extends outward, penetrating into the mating part of the product (photo 3). Otherwise, they are very similar (fixed positions “open-closed”, complete independence from the operation of the standard lock) and thus compares favorably with the widespread central locks, whose electric drives are connected to the “giblets” of the standard door mechanisms. If the car with the “central locks” can be opened with a key or a steel ruler, and in extreme cases, it can simply be unlocked from the inside by breaking glass, then such a number will not work with Defen. A lock without a borehole does not understand any language other than “electric”, and it simply does not have a mechanical drive, either outside or inside. Therefore, the only way to get into such a car through the door is to press the key fob button and disarm the car.
Unlike engine compartment locks, door locks do not have safety cables. Simultaneous breakage of locks in all doors is unlikely, and in case of a failure of the installers, installers can lead a control wire into a secret engine compartment.
The cost of engine compartment locks, depending on the scope of supply, ranges from $ 42 to 65. With the installation, they will cost more - from $ 120 to 125. Door locks are not supplied to the distribution network - you can equip the car at specialized service points. Refining two doors costs from $ 69 to 73, four - from $ 120 to 138.
The reliability of KONTEX products is tested by the brand new editorial “nine”, equipped with four Defen.time locks (front doors, hood, tailgate). The mechanical watchmen are controlled by the Fortress electronic system, manufactured by the Izikom Moscow company. About how successfully Russian technology guards the Russian car, we will tell in the next issues of the magazine.
