Know the year, make, and model.
Vehicle details help identify key type, fob type, transponder needs, and possible service limitations.
Explain what happened.
Locked out, lost all keys, broken key, fob not working, ignition will not turn, or key stuck in ignition.
Have the vehicle location ready.
Use a clear address, parking lot name, mile marker, business name, campground, or nearby cross street.
Be ready to show proof.
Locksmiths commonly need proof that you own or are authorized to access the vehicle.
