That problem was fixed and is not the reason why the DC-10 isn't used any more. The DC-10 (and MD-11 followon, which is still in service) went on to fly millions of safe, reliable hours once the issue with the overcentre locks were fixed with the cargo doors.
The DC-10 is out of (passenger) service now just because it's old and burns too much fuel. (It remains in cargo service, where it will be pressurized).
