My finger sensors stoped working, i can't lock the car

Did you try the pinch method by touching both top and bottom? That's my default method now as cold weather decreases the effectiveness of the sensor.

 

Does the "lock" button on the key fob still work?

 

Given that, on a 12 year old car, I don't think I would worry about it......too much or at all.
Other things likely will be failing soon too and some of them WAY more important.

 

did you do the 4 doors lock unlock, than back to the one door unlock switcharoo a few times and still no joy?
The instructions for the 2010 say to hold all 3 buttons on the fob 5-10 seconds to make the switch in both directions from 1 door to 4 doors and back again.
Of see if the repair manual can help you track down the what's going on.

 

So what's it set at now driver door unlock or all 4 doors unlock when you use the fob?

 

Is there any response form the lock actuator when trying to use the handle sensors?
Have you tried taking off the inside door panel and pulling the electrical connectors yet? to begin diagnostics
Or finding the door handle part #? for possible clues of it's operation
