This key code switch circuit is a type of electronic circuit that is created to replace conventional normal key switch. Without inserts a keys. But you can press the number code instead of unlock keys. We do not have to carry a load key and do not worry about your keys are lost. We just must remember to commit to a code only. Feature of this circuit – For in this circuit uses a four numeric code number and this code number can be changed up to one thousand numbers. – The case with other people to know our original code. They code can be changed easily. The circuit is designed to have the reset system, immediately enter the wrong
