check your fuses if yhey are ok pop a door lock switch out and check for power and ground going to the switch

If they all stopped working at the same time , it's most likely the 'master switch' (drivers door). ALWAYS best to diagnose first , If you're able to , check fuses as already mentioned in first reply then check for power and ground at switch.Depending on labor rates in your area and what it would cost for diagnostics , just popping a switch in may be the lesser of two evils.I'll repeat so I don't get scolded.....test first , guess second(if needed).......and make sure to check ALL fuses (under hood and under dash)
