App / Long Range Remote
We would highly recommend the app / long range remotes as they have multiple uses, can be used as a replacement car key in an emergency but most of all operate over a much greater distance than the standard OEM factory key fob.
In simple terms, the app (phone) either connects directly to the vehicle via a bluetooth connection (short range) or it connects to the long range bluetooth remote which then repeats the signal to the vehicle giving up to a miles connection from your phone also.
The app / long range remotes are two way meaning that they page back to your remote / phone after the vehicle has successfully started. The remote/phone will beep to confirm successful communication and an LED will also light up to display the vehicle has started.
