I just arrived at work, parked up and switched the engine off. When I came to remove the key it wouldn't come out!!?? I ended up using a little bit of force and out it popped. The car locks and unlocks okay and the steering lock enagages but when I try to insert the key it no longer inserts easily, again I have to use a little force to get it in. I then hear the steering lock unlock but when I try to start the engine nothing happens!! Any ideas please???
