Recently, when my wife has been using the car might I add?? When unlocking the car from the fob the drivers door doesnt open, sometimes takes 3 or 4 attempts of locking and unlocking etc?? The little lever on the handle inside the door doesn't unlock and the handle just pulls like the doors are locked? Any idea what I might need done here?? Cheers!

Sounds like the dreaded door lock problems that a few members have posted about.
