I see that there is also a 318K available, a keypad which
appears to use the same receiver. If so, that would be
pretty straightforward. However, not having seen the 318K,
it's not clear how secure it is. Does it simply transmit
whatever you enter to the receiver, or do you set a specific
code in the keypad? I know that both the T and R of the
current setup have to have the dipswitches set the same way.

The manual for the 318K is off the page. There is only the four digit PIN.
No one time codes.
