Our machines are full of all kinds of keys that we often don’t use, but sometimes it’s just necessary to have an idea of their “tasks”. For example, few people know that even cars that have seen their lives have the “Jack” function, designed to help the car owner at the most unexpected moment.
Just imagine that the battery in the alarm key fob or smart key is dead, or that the battery is suddenly “dead”, without which you simply cannot start the engine. And sometimes you just can’t get into the interior of the car. Well, if you have an ordinary mechanical key at hand or there is a pivot pin in the key fob to unlock the doors. But what if the car “cooled” far from home, where is the reserve “empty”?
You will have to break into a car or call a specially trained person who knows how to open and “adjust” clogged doors with master keys. What’s next? How to start the engine blocked by the security system? In addition, many alarms not only interrupt the fuel supply, but also “freeze” the ignition system, as well as “brain”.
Only for such excesses there is a button called “Jack”. This key is intended to deactivate the “guard” in the event of a complete discharge of the battery and an empty battery in the remote control panel. To remove the car from the “signaling”, you need to put the “Jack” function in the off mode – usually this is a black pole with a rounded end, where the button is hidden from the eyes of car thieves.
It is rather difficult to find out exactly where it is, but it is possible. However, after the purchase, almost all car owners are interested in the location of such “chips”, including a hidden immobilizer. In the worst case, the Internet will help, or a phone call to the installation center, where they will install security systems like the one in your car.
Even worse, if the functionality of the “Jack” is protected by a password that neither the car owner nor the installer will remember. Sometimes even specialized specialists cannot restore the combination of numbers and the algorithm for their introduction. This means that the best solution, albeit unpleasant and very costly, is to dismantle the alarm system integrated in the car. And for this you still need to deliver the car to a specialized technical center, because on site, especially in atypical road and climatic conditions, such procedures are practically impossible.
