Common Causes of Remote Start Failure

  • Reprogramming Required: After a battery disconnection, the remote may need to be reprogrammed to communicate with the vehicle's system.

  • Valet Mode Activation: The system might inadvertently enter valet mode, disabling remote start features.

  • Hood Pin Issues: If the hood pin is damaged or disconnected, it can prevent the remote start from functioning.

  • Faulty Wiring or Connections: Loose or damaged wiring can disrupt the connection between the remote start system and the vehicle.

  • Battery Issues: A weak or dead battery in either the vehicle or the remote can cause failures.

Troubleshooting Steps

Reprogramming the Remote

1. Open the Driver's Door: Ensure all doors are closed except for the driver's side.

2. Press the Valet Button: Locate the valet switch (usually under the dash) and press it once.

3. Hold Remote Buttons: While holding down the lock button on your remote, press and hold the valet button until you see a confirmation light (usually a solid LED).

4. Test Remote Start: Attempt to start your vehicle using the remote.

Disabling Valet Mode

1. Turn on Ignition: Insert your key into the ignition and turn it to the "On" position without starting the engine.

2. Press Valet Button Multiple Times: Press and release the valet button 1 to 5 times within 15 seconds. Wait for confirmation (usually a chirp or LED change).

3. Check System Status: Ensure that the LED indicator is not solid, which indicates valet mode is active.

Inspecting Hood Pin and Wiring

  • Check Hood Pin: Ensure that the hood pin switch is functioning correctly. Disconnect and reconnect it if necessary.

  • Inspect Wiring Connections: Look for any loose or damaged wires connected to your Viper system. Tighten or repair as needed.

Testing Battery Health

  • Remote Battery Check: Replace batteries in your remote if they are low or dead.

  • Vehicle Battery Check: Ensure your vehicle's battery is fully charged and functioning properly.

Important Notes

  • If you manage to get your main remote working but a backup remote still fails, consider reprogramming that specific remote again.

  • If none of these solutions work, there may be deeper issues with your Viper system that require professional assistance.
