Electronic Security Door Key Wiring diagram Schematic
A different Electronic Security Door Key Circuit Diagram of electronic lock very simple, one and does not need a lot of materials in order to it is manufactured. The right keys of code should be stepped with the right line, so that is activated the optocupler IC2. If from error is stepped switch that does not belong in the combination, then the lock is trapped. In order to we restore the regular operation of lock, it should we press switches S1 or S12.
Electronic Security Door Key Circuit Diagram
Switch S1 makes Reset of lock externally and the S12 internally, the door. The Code the schema as he is connected it is 147 and it can change, very easily, changing the connections in the switches of keyboard. The optocupler IC2, can drive any exterior schema as Relay etc, ensuring simultaneously electric isolation the two diagram. The schema can be also supplied from a battery 9V.
Part List
R1-7-9=1Kohm
R2-3-4-5=100Kohm
R6 =10Kohm
R9 =47Kohm
IC1 = 4066
IC2 =4N25
Q1-2=BC550
S1...11=Push button sw or keyboard
S12=Push button normal closed
All resistors is 1/4W 5%

Test the movement of the door latch by locking and unlocking the door several times while it is open. If the latch appears to be sticking, spray WD-40 or another household lubricant into the mechanism.24hrlocksmithinlewisvilletx.com
