Hi everybody.. I have a 2007 NCV3 Sprinter 2500 170wb. All of a sudden my keys won't turn in the ignition. I do hear a clicking sound which indicates my key is detected but the key won't turn in the ignition at all. I've tried moving my steering wheel but it won't budge. I've tried changing gears and made sure it's in Park. The lights turn on inside so I know the battery isn't drained. I've also tried using my spare key but the same thing happens. I'm not too mechanically savvy so I'm hoping there's a simple solution. Any assistance greatly appreciated.
