Do you know where the Valet Switch is?Do you know the Model Number of the Viper?
Without knowing the Model Number, this is a guess:
Valet Switch can be located:On the Antenna of the ViperButton Type:Under Driver Dash by Parking BrakeAsh TrayGlove BoxFuse Paneletc.This all depends on the Installer
I would look under Driver Dash & find the Viper Unit.Follow Valet wire to switch (if it's there)
Or, remove Driver Knee Panel & locate the Starter Kill Relay or cut Starter wires & splice them back together
Usually:Turn Ignition ONPress & Hold Valet for apprx. 2 - 5 secondsThe LED should stop FlashingThat would be Valet.
To put it back into Alarm ModePress Valet Switch & LED should start Flashing
