MicroPLUS RF controls are designed to provide maximum RF code security. There are over 268 million remote codes available, plus an encrypted sync code that changes each time the remote is used. These RF controls are ideal for gated communities, apartment complexes, business offices are industrial sites. MicroPLUS codes cannot be copied, making them ideal for use in security sensitive areas.***These garage door remotes come pre-coded from the factory ready to be programmed into your system. If you do not do the programming yourself, you will need the person who does this (HOA Member, Property Supervisor, Building Manager, Gate Service Tech, etc...) to do this for you. ***
