We offer tools for programming machines, chips and transponders

On our website at ProfiKey, we offer tools for programming machines, chips and transponders that support the high-precision electronic devices, true mini-computers, of modern automobile keys, locks and ignition systems.

In the 1990s, car manufacturers began to apply new technologies in the construction of automobile keys and locks and to meet the requirements of passive protection against vehicle theft.


Practically all cars that were manufactured after 1995 have been equipped with anti-theft systems.  At the moment of interaction, “false” key with immobilizer and other road blocks are torn electrical circuits.  As a result, the engine is blocked by de-energizing the network responsible for the operation of the starter and the engine.  This means that even if the thief is able to get into the car, starting the engine becomes almost impossible.


Nowadays, to make automobile keys you need not only have access to special professional equipment, but you also need to have knowledge in the fields of physics, radio engineering and microelectronics.


If the transponder, which is mounted in the key, is incorrectly programmed, the engine will not start.  Currently, there are several generations of transponders and immobilizers.


Modern automobile keys come in a number of styles.  They can be made with and without transponders, which is an immobilization chip.    A remote controlled central locking and car alarm system can be placed in the key housing.  Mechanical keys come in double-sided and four-sided milling.  There are also chiopovat keys and key-cards that can be used to open doors and start engines.  Together, these provide a reliable protection against burglary. 


A car key with remote control is quite convenient, but it is always advisable to have a duplicate key in case of loss or theft.  It should be noted that remote control button on the key cannot be programmed if the vehicle does not support this feature.

If your car suddenly no longer responds to your remote control button on the key, but while the engine can be started, then the remote needs resynchronization.


In case of loss or theft of keys, it is necessary to re-flash the immobilizer—the process in which the key code is removed from the vehicle immobilizer (which prevents the engine from being started with a lost or stolen key).


There are many reasons why automobile key bodies become unusable.  If this is the case, you don’t always need a complete replacement.  The ProfiKey workshop encourages you to replace the key housing.  We can help save you money.


The ProfiKey master will determine the shape of the blade housing option, the type of transponder, radio frequency, the presence of infrared emitters, and will program a complete duplicate for you.

At the customer’s request, the masters at ProfiKey can program car keys.  The work depends on the vehicle model and our technical capabilities.  Usually, this is done using one of three basic technologies:  cloning, adaption, and adjustment of the memory.


·         Cloning: is the fastest and most convenient way.  You must provide an effective key to the ProfiKey workshop and it will be copied on a special programmer.  In this case, the master does not need the owner’s car itself.  The engine immobilizer will not notice the difference between the original and duplicate keys.


·         Adaptation: is the process of matching the radio waves of the remote control with the car electronics and engine immobilizer.  This process requires a valid key and direct access to the car itself.  Also, if there is a PIN code (special password that comes with the care and key), that must be provided as well.  You can snap both original keys from the car manufacturers and inexpensive blanks without buttons.  Each key will be stored in a separate immobilizer memory cell.  Missing keys will stop working after being rewritten; this is used to deactivate lost keys.


·         Correcting memory: if cloning and adaptation fail, correction is applied directly to the key dump and immobilizer.  This is the lengthiest process, but it allows you to selectively add and remove keys. This technology deals with the reading, analysis and reprogramming the memory dump, as well as the search and study of specifications and technical documentation.
