There is nothing more frustrating than finding out your remote start system isn’t working when you need it most. Whether it’s a cold winter morning or a hot summer day, the convenience of remotely starting your Jeep Grand Cherokee from the inside can be lifesaving.
However, there are many potential causes for why remote start might not work in your vehicle. It could range from something as simple as dead batteries to connection issues, fuse/relay Issues, and defective components.
Knowing what these problems are and how to troubleshoot them will help you fix the main issue quickly after experiencing any type of remote start failure in your Jeep Grand Cherokee.
What is Jeep Remote Start?
Jeep Remote Start is an automotive technology that allows you to start the engine of your Jeep vehicle remotely. It can be activated with a button on a key fob or through an app on your smartphone.
With this system, you no longer need to physically get into the car to start it up as long as it’s within range of the remote starter. This feature also offers other benefits like automatic locking and unlocking for added convenience and security.
By having access to these features without having to get out of your car, you can save time and effort while providing yourself with more safety measures when parking in unfamiliar areas.
How Does Remote Start Work on a Jeep Grand Cherokee?
Remote start on a Jeep Grand Cherokee typically works by sending a signal to the vehicle’s computer via a key fob or a smartphone app to start the engine.
The specific procedure varies depending on the year and model of the Jeep Grand Cherokee, but the following steps are generally involved:
- The driver must lock the doors using the key fob or the button on the door handle.
- The driver then presses and holds the remote start button on the key fob or the smartphone app. This sends a signal to the vehicle’s computer to start the engine.
- The engine starts, and the vehicle’s climate control system may turn on to begin warming or cooling the interior of the vehicle.
- The driver can then approach the vehicle and unlock the doors using the key fob or the button on the door handle.
It’s worth noting that not all Jeep Grand Cherokees have remote start as a standard feature, and the process may vary depending on the specific model and year of the vehicle.
Jeep Grand Cherokee remote start not working Causes
There could be several reasons why the remote start feature on your Jeep Grand Cherokee is not working. Here are a few possible causes to consider:
Bad Keyfob Battery
One of the most common causes of a remote start not working is battery-related.
The key fob battery needs to be in good condition in order for it to send signals to your vehicle, so if the battery is low or dead, then the system won’t work.
Additionally, you may need to replace your vehicle’s battery if it is no longer providing sufficient power to start your Jeep Grand Cherokee remotely.
Computer or Electrical Issues
If your Jeep Grand Cherokee’s remote start system isn’t responding when you press the button on your key fob, then there could be an issue with its electrical system.
This problem can often be caused by a faulty connection somewhere along the electrical path between the key fob and the vehicle, such as corroded wires, bad grounds or poor connectors.
which prevents proper communication from occurring. An experienced technician should inspect all related components and repair any damaged parts.
Fuse/Relay Issues
In some cases, problems with remote starting can also occur due to fuse or relay issues within the Jeep Grand Cherokee’s electrical system. Fuses are designed to protect circuits from overloading and burning out;
however, they can become worn out over time due to age and wear-and-tear and will eventually require replacement in order for them to function correctly again.
Similarly, relays are responsible for controlling voltage flow through various circuits but these too can fail due to improper maintenance resulting in a lack of response when attempting a remote start operation on your car.
Damaged Key Fob
Lastly, another possible cause of why your Jeep Grand Cherokee’s remote start might not be working could simply boil down to an issue with its key fob itself – either it has been damaged somehow (e.g., water damage or dropping your keys) or it needs reprogramming.
What to Do if Your Jeep Grand Cherokee Remote Start is Not Working?
If your Jeep Grand Cherokee’s remote start is not working, here are a few steps you can try to get it working again:
- Firstly, check if the battery of your keyfob is low or dead, if this is the case, it may not be able to send the signal to start the car. Replace the battery and see if this solves the issue.
- Secondly, check your settings, your Jeep Grand Cherokee may have a setting that allows you to turn off the remote start feature. Check your owner’s manual to see if this is the case and make sure the feature is turned on.
- Thirdly, check for obstructions, If there is an obstruction in the path between your key fob and the car, it may not be able to send the signal to start the car. Try standing closer to the car or removing any obstacles that may be in the way.
Finally, If none of the above steps work, it may be a more complex issue that requires professional assistance. Visit your local Jeep dealership to have a mechanic diagnose and fix the problem.
