Should My Steering Wheel Lock?

[new big400]

This is pretty sad after owning my car for nearly 5 yrs.I dont know this.Today while sitting in my car with the key out of the ignition I noticed the steering wheel didnt lock.It doesnt turn freely it just doesnt have a set stopping point like a domestic does.It will turn about an eigth of a turn and then you cant turn it not because it is stopped but due to resistance.I thought I remembered it locking.Would someone mind checking theyres for me?Thanks

By the way a 98 gs4

It locks completly only when turned all the way to one side.

It makes it eaiser to unlock the pin for the wheel.
