Improper Starting Procedure
Vehicle Not in ‘Park’
Too Many Remote Start Attempts
Coolant and Oil Pressure
Double check your engine coolant and oil temperatures: If the engine coolant temperature is too high or the oil pressure is too low, remote start is disabled! After you have let the car cool down for 5-10 minutes and rechecked the levels, retry the start procedure.
Hazard Warning Lights
The Key is in the Car
A simple fix may be the location of the key. The vehicle cannot be started with the fob in the car. Take it out of the vehicle and retry step #1.
Check Engine Light
If the ‘Check Engine Light’ or Malfunction Indicator Lamp (MIL) is illuminated, the remote start system will not work. Don’t panic, one of the reasons the MIL can illuminate is due to a loose gas cap! Reseal the cap, restart the car, and retry step #1!
Dead Keyfob Battery
If none of the other solutions have fixed your remote start problem, try replacing the battery in the fob. The keyfob uses a CR2032 lithium cell watch-type battery. The battery is commonly found and can be easily swapped using the diagram on the right.
Check the Manual
It might be time to dust off the old, trusty manual. Your vehicle may include additional features that are preventing the remote start function from working. If other troubleshooting fails, have a look at the manual for the ‘Remote Start Procedure’.
