After unlocking or controlling the door lock, the time IC (IC ₁ ) is instantly restored and all operation circuits by the recovery of the relay (RY ₁ ) are shut off, thereby protecting the door lock control switch. This circuit can be protected by cutting off the power supply. When the key is inserted into the lock (H ₃ ) of FIG. ₃ , the terminal (t ₁ ') (t ₂ ') is connected to the power supply to the time IC (IC ₂ ). is supplied to the relay (RY ₂₎ is a high potential is generated and instantly operating divided by the time the lock control circuit nine minutes chairs Of the trunk, and then instantaneously supplied to unlock the trunk opener, etc. The (time-IC (IC ₂₎ is restored is to block all operating circuit protects the opener and the present circuit.

It is impossible to start the engine and unlock the door by any method because it operates by connecting the operation state of the existing engine start and the door well to the electronic design of the present invention, even if the car window is destroyed for theft of the car. Since there is no lock pin, it is not possible to unlock the door and prevent theft, and even if you can get into the car, you can start the engine from the moment the object touches the seat and start the engine. As a preventive purpose. In addition, the key classifies the voltage classification range from the voltage mv, and at the same time, the number of keys can be infinitely changed by replacing and spacing the terminals t ₁ , t ₂ , t ₃ , and t ₄ . Only when the key is inserted into the lock (H ₁ ) (H ₂ ) (H ₃ ), all the operating current flows and is blocked, and the key is not inserted into the lock (H ₁ ) (H ₂ ) (H ₃ ). In this case, only a small current flows in the transistors Q ₆ and Q ₇ , and all circuits can completely ignore the current consumed because the power is completely shut off. If the power supply voltage falls below the operating voltage or is completely consumed, the key terminal shown in FIG. 2 can be unlocked by connecting the battery to (+) (-) and unlocking the door by simply inserting the key. It is a useful design that is easy to use and very reliable.
