Hi, my name is***** your problem is that you cannot turn the key in the ignition when it is very cold you will need to replace the ignition switch. This is a fairly common complaint in northern climates. Replacing the ignition switch or warming the interior of the car will cure the problem.

Let me know if you have any questions.
