2011 Honda Fit Sport Left Driver Door Actuator Latch Assembly

I have a 2011 Honda Fit Sport. The driver side door lock is stuck. It won't lock or unlock manually, using the key, or using the auto lock switch. The auto switch will lock and unlock all the other doors and the hatch. The actuator seems to still have power. The lock is just stuck. So it may be the latch, or something else. I'm not particularly mechanically-inclined, so I haven't attempted to take the door apart and investigate myself. Either way, from what I understand, the actuator comes as part of an assembly with the latch and cable. This assembly for the 2011 Fit Sport costs around $240, with no aftermarket available. I have found the part used on eBay for around $50, but only for the 2009 or 2010 model. I can't find the 2011 used anywhere. Will either of these model years, 2009 or 2010, or any other model years, fit the 2011? They all seem to be year specific. Did Honda honestly change the front left driver side actuator-latch assembly each model year? I have been unable to find this information anywhere. It's frustrating, to say the least. Thanks in advance to anyone who can help.
