How Do You Fix Jeep Wrangler Remote Start Not Working?

How Do You Fix Jeep Wrangler Remote Start Not Working

Here is a rundown of the possible cause of the Jeep Wrangler remote start not working and their solutions:

1. The Gear Selector Is Not In PARK

For the remote start to engage, the vehicle must be fully secured. The gear shift must be in the park position so the vehicle does not roll away unexpectedly when you start it remotely.


Move the gear selector to the Park position. Check that the gear selector is fully engaged in Park. There may be an obstruction preventing it from latching properly.

2. The Doors Are Open

All doors must be shut for security reasons before you try to activate the remote start. This ensures no unauthorized person enters the vehicle when you start your Jeep remotely, protecting your belongings.

  • Shut and securely latch all doors. 
  • Confirm all doors are fully closed by pushing on each door handle to verify it will not open. 
  • Check for obstructions preventing doors from fully closing or latching. Also, all the removable doors must be installed.

3. The Hood Is Open

Remote start won’t engage when the hood is open to avoid accidentally activating parts beneath the hood that someone may be working on. This helps prevent injuries and damage. There is a pin that gets pressed when it is closed.


  • Close the hood and ensure the hood latches engage securely. 
  • Verify the pin isn’t broken. They are two prongs on the right side under the hood that get pressed when you close it. 
  • If broken or faulty, replace it. All you need is to pop the side snaps and pull it out.

4. The Swing Gate Is Open

With the swing gate or the tailgate open, it’s possible for someone to access the vehicle’s cargo area, defeating the security of remote starting the vehicle. 

Also, it’s possible that exhaust fumes could fill the cargo area, which is a safety hazard. So, there is a safety switch that prevents you from remotely starting your wrangler when it is open.

  • Close the swing gate completely. Make sure it latches securely. 
  • Look for any obstructions that may be preventing the gate from fully closing or latching and remove them. 
  • If the latch mechanism is faulty, repair or replace the mechanism. It’s easy if you follow the provided instructions in the manual.

5. The Hazard Lights Are On

With the hazard lights on, the vehicle thinks your vehicle has become a potential hazard for other road users preventing remote start as a safety precaution. The hazard lights need to be off to allow remote start.


Turn off the hazard lights. Check that the hazard light switch is functioning properly and not stuck in the on position.

6. Battery Voltage Is Too Low

A sufficiently charged battery is required for the remote start system to function properly. Thus, a low-voltage battery cannot provide enough power to start the vehicle.

Jeep Wrangler Battery Voltage Is Too Low


  • Check the battery terminals are clean and tight. 
  • Test the battery voltage using a multimeter – it should be above 11-12 volts. If low, recharge it. 
  • If this repeats or you experience repeated jumps, replace the battery. 
  • Also, check for electrical drains that may be discharging the battery. 

In that sense, 

  1. You want to make sure the car is in park
  2. All the doors closed and everything is turned off
  3. Set the multimeter to amps
  4. Remove the negative battery terminal and measure the amperage passing between the battery terminal and the connector. You should get 0-50mA. Anything above this will indicate you have a parasitic battery drain. 

7. The Panic Button Is Pushed Or Being Pressed

The panic button, if pressed, will prevent the remote start from functioning as a safety measure. This is to avoid accidentally leaving the panic alarm active after remote starting the vehicle.


Release any buttons on the remote that may be stuck and depressed again to ensure it is not stuck in the On position. Replace any faulty remote fobs that have stuck buttons, which you can get from a Jeep dealer or online stores.

8. The engine or Malfunction Indicator Lamp Is Illuminated

The malfunction indicator lamp, or check engine light, indicates an issue with the vehicle. That needs to be addressed before remote start can activate. It is meant to avoid unintentionally running vehicle systems that may be faulty.


Use an OBD scanner. It will show check engine light code to identify what caused it to light up. Once you identify the root cause, you can decide to DIY fix it or take it to a technician if it’s a more advanced issue. Once the underlying issue is resolved, the check engine light should turn off, allowing the remote start to function again.

9. Remote Start Is Disabled From the Previous Event

Jeep Wrangler remote start system allows you to have two attempts to press the remote start. Otherwise, you’re required to start it normally to reset the trials. If you don’t, your Jeep won’t start, no matter how many times you try. So, if previously it has been attempted twice, it would not work unless you reset it.

Be certain this is not the issue by resetting the remote start. This requires you to start the normal way – insert the key and turn on the ignition. Allow the engine to run for a few minutes and turn it off. That should reset the remote start attempts. 

10. Ignition Isn’t STOP/OFF Position

For remote start to activate, the vehicle’s ignition must be in the “off” or “stop” position when you lock the vehicle and arm the alarm. This allows the system to register that the car is off and ready to be started remotely.


Ensure to put the vehicle’s ignition into the “off” or “stop” position, remove the key fob, lock the doors, and test the remote start function. 

11. Your Wrangler Is Low On Fuel

For the remote start feature to activate, your Jeep Wrangler must have at least 1⁄4 of the fuel, or approximately 3 gallons of gas remaining. This minimum fuel requirement ensures the engine has enough gas to run for the duration of the remote start session.

Jeep Wrangler Is Low On Fuel


Fill your Jeep Wrangler’s gas tank to above 1⁄4 tank, or ideally, at least 1⁄2 full. The remote start system should function properly once you meet the minimum fuel requirement.
