MicroCLIK RF controls are designed to provide convenience and security. MicroCLIK transmitters are factory coded to 1 of over 1 million available codes. These RF controls are ideal for single-family homes, gated communities, apartment complexes, business offices and industrial sites. MicroCLIK transmitter codes usually can be copied into the built-in transmitters found in many luxury automobiles; however we do not guarantee this commonality or functionality.
