newbie's question about car alarm transmitting freqencies
ok, i dont have a car alarm installed, infact i never really understand how they manage not to screwup. i mean i observed that most alarms transmit signals at apprx 330Mhz.
Now, how come one alarm does not open the doors of another car. say, if 1,00,000 people bought the same alarm module from the same manufacturer, is the probabilty of mismatch > 0? just wondering.
also, if i buy a transmitter unit like http://www.partsexpress.com/pe/showd...number=330-145 can i program the alarm myself, like set the transmitting "key" code manually. \
