Homelink

from Wikipedia, the free encyclopedia

HomeLink is the product name for a multi-frequency radio transmitter that is now available from many automobile manufacturers as a built-in accessory.

functionality

The system was manufactured and developed by Johnson Controls and was taken over by the automotive supplier GENTEX Corp around 2014 . It was installed in over 20 million cars in 2003. The system works like a “cloned” programmable remote control to replace the remote controls for garage doors, radio controlled lights, gates, etc. In order to use the system in the vehicle, an original remote control must first be taught (made known) to the system in the vehicle for the desired function.

The system has several buttons, often integrated into the dashboard, the driver's side sun visor or the rearview mirror. Integration into the infotainment system is possible in newer vehicles . The system is compatible with many wireless garage door openers from the frequency bands 27 MHz, 40 MHz, 434 MHz and 868 MHz and home automation systems that are unencrypted or based on the 10-bit encryption protocol or rolling code technology.

Incompatible radio systems

Since around the end of 2016, the 27Mhz and 40Mhz frequency bands in the vehicle are no longer supported by the system in newer HomeLink systems. Many hand-held transmitters from the 70s, 80s and 90s can no longer be taught-in.

Newer generations of handheld transmitters from around 2015 that work with more modern encryption systems, for example with the KeeLoq hopping code , can no longer be integrated into the system either, because these hopping code processes cannot be copied ( unique transmitter bidirectional radio), although they operate at 434 MHz Radio technology work.

The system won the 1997 PACE Award for improving the interaction between people, cars and building technology.
