Q. Can a solenoid be added to the circuit?
A. Hi Stuart, thank you for your question. The keypad only sends a BCD signal. You would need a microcontroller to interpret the BCD. A solenoid cannot be directly driven unfortunately.

Q. How do i program this keypad, I've been trying for just under a year now and I still don't know how to use it. don't ask me to look at "data sheet" because I have 20 times over so please give instructions on reply. Thanks
A. Hi Jack, thank you for your question. An interface like an Arduino or Raspberry Pi would be needed to connect with the keyboard encoder kit so the code that is outputted from the keyboard would be translated into an output for a lock for example. Please see here for a tutorial.

Q. How many digit passcode could I use?
A. Hi Harry, thank you for your question. This is an encoder to output a code, any numbers of codes or digit pass codes could be used. It would depend on how long a code was programmed and what was used to decipher the code i.e. Arduino programmed to receive a specific pass code etc, please see the data sheet.

Q. is there a master key or a reset button on this Keypad just incase you forget the passcode also how many Digits long can its be?
A. Hi Asif, thank you for your question. No master key or reset is available as this only outputs the binary code. A receiver or programmer would be required to allow a code to be used. Please see the data sheet.
