Key wont turn

My key wont turn from positon zero unless I pump the brakes for abot 30 seconds, it sounds like air is coming out of my front defrost vents on the dash. After a while the key starts and the car runs normal. Any ideas before I take it to the shop?

Vacuum leak in the booster pump?

is that expensive, would it also cause the check engine light to come on?

I cannot imagine a link between the ignition switch and the brake pedal.

Next time it happens, jimmy the steering while while turning the key.

Dunno what the problem is ... but others have had the same problem and have been given similar advice ...

So it behooves you to see what they did (and what they were told).

A quick /steering wheel(F3) in the bestlinks nets me the following.
