A worn out Power Steering pump, or steering box.
To unlock the steering wheel on a 1993 Honda place the key in the on position. Doing so will free the steering wheel.
Take it back to the alignment shop and they should re-do it for free. If you paid for it, your steering wheel should be straight.

Worn steering components
You can adjust the steering box some. Or possible ball joint problems. If the problem is lurches and surges in the steering (can feel like loose idler arm, loose ball joints, etc.), one common cause is a faulty steering position sensor. This $60 sensor at the base of the steering column (inside the vehicle) tells the variable assist power steering how fast you are turning the steering wheel.
Sounds like a burned or warped brake rotor. Have them inspected at a reputable shop. Some even do this for free! Call around first.
If the steering wheel spins freely but the wheels don't turn, the steering shaft (which runs from the steering wheel, into the engine compartment, and down to the steering box) probably came apart. Usually there are one or more joints in the steering shaft, to allow it to angle around obstructions in the engine compartment. It may be that the shaft separated from one of these joints. Find the steering shaft in the engine compartment and see if it's continuous all the way down to the steering box. Also see if when you turn the steering wheel, if the shaft turns also. If it doesn't, then there's a problem with the steering wheel's mounting to the shaft. At the steering wheel, the shaft is usually cut with a bunch of little notches, which the steering wheel hub slides onto. If these notches have gotten stripped, then the hub has nothing to grip, and the wheel will spin free without moving the steering shaft.
If the gearbox is causing freeplay in the steering wheel, then the gearbox needs to be replaced.
steering wheel in locked positon try moving it a little either way and the key should turn. The steering wheel has a locking device that wont let the key turn if the wheel is not free or you have the Wrong key
If you're sure that it is the right key then, the next thing to check would be: is the steering wheel lock bound up? Turn the steering wheel hard first one way then the other while attempting to turn the key. If that doesn't free it, then you might have a park/neutral safety that won't disengage.
Are you having a problem with the column getting extremely wobbly? Phil
