What are common reasons my Jeep Cherokee remote start isn’t working?

The most common reasons for a Jeep Cherokee’s remote start not functioning include low battery in the key fob, poor signal reception, or issues with the vehicle’s security system. If the battery in your key fob is dying, it may not send a strong enough signal to engage the remote start feature. Additionally, factors such as obstructions between the key fob and the vehicle, or distance limitations, can impede signal strength.

Another reason could be related to the vehicle itself. For example, if the engine is not properly secured (like if a door is ajar or the hood is open), the security system may prevent the remote start from engaging. Issues with the vehicle’s electrical system or software updates may also impact the functionality, making it essential to check various components before concluding that the remote start is broken.

How can I troubleshoot the remote start issue on my Jeep Cherokee?

To troubleshoot your remote start issue, begin by checking the functionality of your key fob. Replace the battery if you suspect it may be weak, and try the remote start again. It’s also important to ensure you are within the operational range of the remote start system, typically around a few hundred feet. If obstacles like walls or buildings obstruct the signal, consider moving closer to your vehicle.

Next, inspect your Jeep Cherokee for any open doors, the hood, or if the transmission is in the correct position (typically ‘park’). Make sure the electrical system is in good condition and that there are no warning lights illuminated on the dashboard. If none of these steps resolve the issue, consult your owner’s manual for further guidelines and consider reaching out to a professional technician for assistance.

Could there be a problem with my key fob?

Yes, problems with the key fob can significantly impact the remote start function. A dead or low battery can prevent the fob from sending a signal to the vehicle. Even when the fob’s buttons seem functional for unlocking or locking, it may still lack enough power to start the engine remotely. Additionally, physical damage to the fob or internal circuitry issues can also prevent the remote start feature from working.

If you suspect the key fob is the issue, try using a spare fob if you have one available. If the spare works and your original does not, replacing the battery or the entire fob might be necessary. If both fobs fail to initiate remote start, this could indicate a deeper problem within the remote start system or the vehicle’s security features that may require professional diagnosis.
