Compatible with all Linear access receivers & controllers Quick-disconnect key ring Factory programmed MegaCode format supports more than 1 million codes Includes two 2016-type lithium batteries Operating freq: 318MHz Linear's ACT-34B is a four-channel device supplied with a quick-disconnect key ring and a unique 10-second time-out feature. Each transmitter is factory preprogrammed with one of over 1,000,000 codes, virtually eliminating the possibility of code duplication. No unauthorized person can gain access by reprogramming a transmitter because the receiver learns each specific code. Block coded transmitters are factor programmed to a sequential series of transmitter id codes and facility codes can be selected to further customize the system.
So this complex I live in uses these exact transmitters but they sell it to us for $45 which is a total ripoff. I bought this on Amazon and asked the front desk to program it. It works! They only needed the code on the back to program it. So no, you cannot self program it if it is part of a public complex.
