I'm in the middle of repairing this right now on my 2000. I noticed that in addition to the two anti-theft bolts that need to be removed, there is another bolt on top of the SCLA that when screwed all the way in, is supposed to align with a hole in a rotating assembly that is inside the steering column. I believe that if this is not aligned, then it won't hold the lock in place and when you turn the steering wheel you might get the behavior that you are seeing.

Look at the "rear" of the engine where it joins the transmission. Follow the positive cable from the battery to it. Cog with the 'teeth' you see engages the flywheel to start the motor.

It looks similar to this.

My information shows that your vehicle has High beam lamps and Low beam lamps .. they are different . which one did you buy?

1) If you bought 1 that is looks like this

It is the High beam lamp

2) If you bought 1 that looks like this

It is the Low beam lamp

The ignition crank shaft is broken inside the Steering Column Lock Assy. You will need to buy a new assy (cost appr. $202.21) and 2 steering lock bolts (cost appr. $4.96 ea) at a Toyota or Lexus dealer. Call either dealer for best price and availability. To replace you'll need to remove the black snap-on panel below speedometer then remove the screws securing the driver side dash. Behind the dash is a steel plate. Remove that and remove the steering column covers by turning the steering wheel to access the screws. You'll see that the SCLA is secured by 2 break-away bolt (this is an anti-theft feature). Use a dremel tool with cutting disc to make a notch in the screw head to remove with a flathead screwdriver. If this doesn't work your other option is to cut the bolts where the assy bolts together. Remove the broken SCLA and remove the key FOB and install into new SCLA. If your mechanically incline this should take about 2-3 hrs. and save you $300-400 in labor cost. Part numbers are same at Toyota and Lexus dealers.

not to sure if they sell them in shops but it should only be the springs so if they do sell them price them up and it should be cheaer, not 100 percent on that tho.
