Plastic Injection Tooling Quality Control

  With the development of automobile technology, car keys have more and more functions. But after a long time, the key suddenly lost power, which made people worry. Today we will talk about the life of the key and how to deal with it when there is no electricity power.

The functions of the remote control key:

The first generation:  the traditional mechanical key realizes the basic door switch function.

The second generation: You can press the remote control button to open and close the door, but the car needs a mechanical key to operate. The two keys are used together, which is indispensable and cumbersome.

The third generation: combining the functions of the key and the remote control into one, the door opening / closing / car activation are all completed by the active button, and the mechanical key is embedded in the remote control key.

The fourth generation: on the basis of the active buttons, a passive working mode is added, and the door opening or closing action can be realized without pressing the buttons, which further improves the efficiency and greatly improves the safety performance.


  As you can see the above picture what Asia Billion made , the life one is the third generation key and the right one is the fourth generation keys. 

Working principle

  The working principle is simple: first, a radio wave is sent from the key, the radio wave signal is received by the car antenna, the signal code is recognized by the electronic control unit (ECU, Electronic Control Unit), and then the actuator of the system (motor or solenoid) can do the opening or closing actions.

What should I do if the car key is no electricity power ?

  The remote control key will show some signs when there is almost no power, such as the distance of the remote control becomes shorter, and sometimes it does not respond when pressed. To prevent the remote control key from running out of electricity, it is necessary to find and replace the battery in time. It is also very simple to replace, and it is also available in convenience stores with button batteries. When installing, carefully identify the positive and negative poles of the battery and do not misplace them. you also need to keep spare keys in case you need them.

    you also can open them by the mechanical key. Insert the mechanical key into the key opening under the door handle cover, then pry the trim cover upward, insert the key into the lock cylinder and unlock the vehicle . you need to use a mechanical key to manually lock the door after parking too.

   Asia Billion is TS16949 certified automotive injection mold manufacture with small size , so we are flexiable enough, much quicker response , low management cost and have lower total price than the big companies who has the same quality system.   If you want find a good performance automotive injection mold maker such as this car key plastic injection mould making project. we think Asia Billion will be your best choice .
