Some new DEI Viper 2-way remote start aftermarket alarm system models use a remote with FCC ID EZSDEI7756. DEI used a similar remote on some alarm systems that carry other brands as well. This transceiver both sends and receives radio-frequency signals in its communication with the control module in the vehicle. The remote operates at very high frequency . . . a range around 915 mHz. The keyfob has 5 buttons and an LCD screen to display the information returned back from the vehicle.
As with nearly all aftermarket alarm systems, this system can be programmed by the user to accept a new remote through the valet switch.
