Yes,the lock mechanism has either gone bad and needs replaced or is disconnected from the system.Whether it be accidentally disconnected while repairs being done or wire fell loose,pull the door panel and check it.If connected and has power when checked with a test light,it should work.If has power and no action,replace it.

you can buy fuse removal tool or use needle nose pliers to remove fuses that what i use..no power locks could bad relay.

Open the doors, on the door jamb of each door is a small switch with a diagram that shows the switch position to turn the locks on and off.

It's a year old. Take it to the dealer immediately and have it repaired under warrantee. Don't wait too long or they might say further damage was caused because you didn't get it looked at immediately.

I had a wire connector on the front of the engine that had so much tension, the wires broke. I didn't notice until a wet day when the car wouldn't start (and the Check Engine light was on). (The error code was related to an Emissions error.) The connector is located on the engine, front, just left of center. Hope this helps!

ouch thats a pricey one you have to replace the head unit there is no lock out for the buttons so if they dont work its a mechanical failure and its all one seald unit screen and all and it costs just shy of 2500.00 dollars
