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.
