The 441 remote was installed, but unfortunately I was disappointed. The remote control only gave me 20 meters or less. Contrary to what was mentioned about it, it gives more than 500 meters and all I need is 100 meters without obstacles. I placed the device in more than one place on the glass, but it was of no use

Please, I need support. Is there any settings or something?

There are no settings that change the range of remotes. 

Several factors may affect the operating range of the remote transmitter:

  • A weak transmitter battery.
  • The operating environment such as in the city and airports due to radio interference, cell phone towers, etc.
  • Several types of metal such as the vehicle itself, other vehicles, the windshields tint lines and large buildings.
  • The vehicle’s shape. Vans generally have poorer range.
  • The shape of the vehicle’s roof and the A-pillars cause considerable radio-frequency deflection. As a result, the direction in which the vehicle is facing with relation to the remote transmitter can affect range. Facing the front of the vehicle generally produces the greatest range; secondly facing the back. Facing either side of the vehicle will usually give the poorest range.
  • The range will be significantly poorer in crowded parking lots as opposed to empty parking lots.
  • Hold the transmitter at shoulder height or hold it against your chin so your body acts as a larger antenna.
  • The operating range will be somewhat poorer on vehicles equipped with a factory alarm or keyless entry system.


I quick suggestion would be to drive a few kilometers away from your current position and try the remote fob there to see if you get better range. If you do, then there was RF interence.
