I searched the forum and other places, found a common problem of 'faulty ignition switch'... now could this be the reason for this noise I get upon starting the car, happens now and then, but seems more frequent now

Ignition switch is a cheap part... but have to remove steering wheel and faff about fitting to fit a new one, long and fiddly job according to the haynes manual (even drilling out a bolt so the old switch slides out of its housing!) beyond me I think
Any ideas?
