Common Questions
How do I know this is the right key for my Jeep?
Check your current remote for FCC ID: M3NWXF0B1. This 4-button version is for models without the power liftgate button on the fob.
Why can't I program this key myself?
These vehicles are equipped with a "Secure Gateway Module" (SGW). Only a professional automotive locksmith or a Jeep dealership with authorized diagnostic software can bypass this security layer to program a new smart key.
What happens if the remote battery dies?
The fob contains a hidden emergency blade. You can use it to manually unlock the door. Once inside, you can typically start the vehicle by pressing the push-to-start button directly with the tip of the key fob.
