Why wont the key come out of the key switch?

Take a small rubber mallet and tap the key. This is assuming the car is in park (automatic only) or manual transmission. The key should come out without issue. This should be enough to loosen up the parts on the lock cylinder that are binding. You may want to replace the lock cylinder at this point to ensure this doesn't happen again.

One issue in premature key/lock wear is the fact that a lot of us like to have a kilogram or two of extra keys, fobs, and bangles on our key rings. This mass, flailing about whilst you drive, certainly does the lock no good! Also, a little lock lube on the key can certainly help improve life.

Frank thank you you where wright on the money. Shifter sleeve was stack in down position ewer slightly. I pullet it in up position and key come out.
