Hello. When I turn off the car, the steering wheel does not lock, which is why I cannot lock the car with the button on the keys. I was told that when choosing a new ignition switch I should pay attention to the small hole near the lock itself where the key is inserted. Where there is a hole - it is an automatic, where there is none - it is a manual. My question is - what will happen if I install an ignition switch from a car with an automatic transmission on mine, which has a manual? And also when choosing the right ignition switch, what numbers to pay attention to? Of course I will choose used and sometimes the lock itself is sold without keys, can I use my old key provided that all the numbers match?
