Wireless transmitters usually are uncoded and once programmed they stay with that code. This wireless security transmitter is cool because it has all the jumpers on top that make it a fixed code that can be changed anytime. This is what we use for testing relays and other remotes since the code can always be modified. The range is not long and the antenna is not included with this model. Its always good to have one of these transmitters in your tool kit.
