Antitheft combination lock for car - has ignition block coupled to mileage counter for continuous change of code

摘要

The anti-theft combination lock has an input counter of several decades and a drive coupling to the mileage counter. The driver reads the mileage figure on the tachometer and adds the secret code to obtain the new code for releasing the ignition block. The code is constantly altered as the vehicle is driven, with the code setting altering at the same time. The system is simple to install and provides maximum security as the required code constantly changes.
