Be very careful, Just recently I had an ignition switch that went wrong. It ended with the starter motor burning out which was very frightening I couldn't turn it off because of the faulty switch, my wife and I stood and waited for the car to go up in flames, which fortunately it didn't but lots of smoke. To cut a long story short, RAC recovery, Taxis, Hire car, costs to me nearly £1,000 and that was with the RAC paying recovery and Taxi's. The first clue which I did not realise at the time was the steering wheel not always retracting. Get it fixed now!!
