Remote control Valcor TX33 with hopping code

It works with the products manufactured by the company Lesi, (Valcor VCB, Valcor VCH, Valcor VCL1, Valcor VCL2) which are controlled by remote control. (Battery is included)

The advantage of Valcor remote control locking systems is that they have no visible elements. The modules are mounted on the inside of the door and only you, using the buttons on the remote control, manage the lock. Valcor remote controls have 64 bit code. They have a jumping code, which means that every time a button is pressed, a different code is emitted, which cannot be duplicated by ill-wishers. . The code hopping is expressed in a pseudo-random sequence, moving according to a different, unique algorithm for each remote control. In the modules for/with remote controls manufactured by Lesi, an anti-code scanning system has been introduced and it is not possible to hack into the system even by listing random combinations. If there was an attempt to penetrate the system through the remote control, it considers it a loss of synchronization and will automatically ask for remote identification through the so-called synchronization procedure.

A disadvantage of remote controls is that they work with a battery that is consumable and can be used up at an inopportune moment. The remote control itself is relatively complex as a device, allowing it to be damaged by getting wet, bumped, dusted, etc. Another disadvantage is that the transmission of the code uses the airwaves, which can be intentionally or unintentionally jammed and the signal from the remote control cannot reach the control panel at that time (the remote does not work).
