No start with “No Key Detected” although the remote locks and unlocks (2024–2026 Ford Mustang)

Engine / equipment

Seventh-generation Ford Mustang

Period mentioned

2024–2026 (US model years)

Symptoms

The engine does not crank or start and the cluster shows “No Key Detected”; the key does not work in the backup slot either, although the remote still locks and unlocks the car.

Possible cause described

Ford gives no cause but does give the fix: try starting with both keys, reprogram both if the fault remains and, if it still does not start, replace the body control module (BCM) (message SSM 55118).

Check for the garage

Try starting with the other key; if that does not work either, ask the workshop to follow SSM 55118.
