Can you upload the circuit for you switch to encoder circuit feedeing the PICAXE inputs?As for the other bits... I have a 4 x 4 keypad of which the outputs are encoded into binary and fed into an encoder ready to be transmitted. Once transmitted they are received and decoded back to binary. It is this binary that is being input into inputs 0 - 3 of the PICAXE.
Are you using a chip such as the 74C922 as the keypad encoder?
Are you sure that part of the ciruit is working correctly?
