Range Rover Sport Key Not Detected, What It Means & How to Fix It

Seeing a “key not detected” or “smart key not found” message on your Range Rover Sport dashboard is unsettling, especially when your key is sitting right there in your pocket. The good news: this is a well-understood fault, and in most cases, it has nothing to do with the key itself.

“Smart Key Not Found”, What This Warning Actually Means

This message tells you the vehicle isn’t receiving a signal from your key fob. That could mean a flat key battery — or it could mean the vehicle’s own detection hardware, the KVM, has stopped working properly.

Is It the Key or the Vehicle? How to Tell

A simple way to check: if you have a spare key and it also fails to be detected, the fault almost certainly sits with the vehicle, not the key. If only one key fails while another works fine, it may be an issue specific to that key.

The Most Common Cause: A Failing KVM

On the Range Rover Sport, a worn or failing Keyless Vehicle Module is by far the most frequent cause of this warning appearing across all your keys at once. It’s a known issue on this model as the vehicle ages.

What Happens If You Ignore This Fault

Left unresolved, a failing KVM tends to get worse — intermittent detection issues often progress to the vehicle not recognising any key at all, leaving you locked out or unable to start the car.
