rf remote using 12f629

hi every body...
can any one give me schematic of this type of remote key fob?
these remote r contained of:
----------
transistor:
m6
3em
r25
-------
micro:
pic12f629
-------
12v battery(27a)
-------
and so many resistors and capacitors
-------

i did reverse Engineering on these circuit & found out m6 is a voltage regulator,3em & r25 r high Frequence transistor for rf application.
i found out there r 2 radio circuit ,r25 circuit which is connected to pin 4 of 12f629 and 3em circuit which is connected to pin 3 of 12f629.
i cant understand relation between these to circuit.
this is so confusing!
i know these type of circuit managed by tow pin of micro.first pin is names "boost" and second pin is named "pulse".
i have more info about that if any one wants to know.
and there is a interesting way to copying these remote which the main course of this project!
im waiting for your corporation my friends.

Please Post your Circuit Diagram.

pls illustrate the circuit more as it is unclear

i will prepare circuit diagram for u but i draw it by trace the rout on the remote which i have.its not RELIABLE.the important things which i want to know is the way copying another remote on this type!
when i hold a button of first remote,and push a button of second remote near by first one,the data become saved on first remote.i do it for all button then i have a copy of second remote.
as soon as i prepare circuit diagram i will post it.
