My key fob unlocks my car but won’t start it.
What to check before ordering a replacement fob
A working unlock button tells you the car received a remote command. Starting also requires the vehicle to recognize an authorized key. A replacement might help, but the symptoms matter.
Try the spare and the backup starting position
If you have a second key, see whether it starts the car. For push-button vehicles, check the owner’s manual for the backup starting position for your exact model. Note whether the vehicle starts there and the exact dashboard message. If both keys behave the same way, tell the locksmith before buying another fob.
A Range Rover example from our diagnostic work
On a 2018 Range Rover, the remote buttons worked and the vehicle started when a key was held near the steering column. The same symptom appeared with multiple keys. That distinction helped narrow the question to why normal proximity starting failed. A remote-button test alone could not answer it.
What to send First Key
Send your year, make, model, ZIP code, dashboard message and the results with each key. We’ll discuss whether the next step is a key check, programming or vehicle-side diagnosis. Call (305) 518-8501 or see mobile car key programming in Kendall.
