To address the issue with the keyless system in a 2015 Jeep Grand Cherokee, there are a few potential solutions to consider. Firstly, it would be advisable to use a scanner that reads extended codes to scan for any stored codes related to the key system.
Autoenginuity is mentioned as an effective but expensive tool for this purpose. Alternatively, the manufacturer, FCA, offers a more affordable tool that can also read most extended codes.
In cold weather, it’s possible that reduced battery power in the key fobs could lead to a “Key Fob Battery Weak” message. This can be resolved by ensuring the key fobs are warmed up, which should eliminate the message.
Regarding the issue with the door handle keyless entry-n-go feature not working after installing aftermarket audio, it is essential to check all connections and ensure that there are no loose wires or faulty installations. If both key fobs have been tried and the keyless entry is still not functioning, it is recommended to check if any other electrical components have been affected.
While remote start and lock/unlock functions still work with the key itself, it would be helpful to verify if any error codes are stored in the system that may provide more specific information about the issue.
To avoid visiting a dealership, seeking assistance from knowledgeable individuals or automotive forums could be a viable option. One suggestion mentioned the possibility of a disconnected rear sensor, but its exact location or purpose is unknown.
It would be beneficial to research the potential location and function of this sensor to determine if it could be related to the keyless entry issue.
In conclusion, utilizing a scanner to check for stored codes, inspecting the key fobs for battery power, examining aftermarket installations, and seeking advice from knowledgeable sources are all steps that can help address the keyless system issue in a 2015 Jeep Grand Cherokee without having to visit a dealership.
Key Points:
- Use a scanner that reads extended codes to identify any stored codes related to the key system
- Consider using the expensive but effective Autoenginuity tool or the more affordable manufacturer tool to read extended codes
- Warm up key fobs in cold weather to resolve “Key Fob Battery Weak” message
- Check all connections and installations for aftermarket audio to ensure the door handle keyless entry-n-go feature is not affected
- If keyless entry is still not functioning, check for any other electrical components that may be affected
- Research the potential location and function of a disconnected rear sensor that could be related to the keyless entry issue.
