1999 Lexus LX470 Steering Column Lock Assembly:

is the lock assembly in the car or out?
there are 2 jobs here, removing the assembly
and after that, attacking the lock it self.???????

any lock smith can rebuild the lock, proper
it has pins that are pressed out.
it can even be rekeyed.

the remove assembly is covered in the FSM, no books?
alldata.com covers that.
it really is an Isuzu. impulse.

my guess is its job 1, assembly out.
so toss coin lands on job1
(on most cars, steering wheel must be removed)
once that is done, its obvious from there, right? that clamp there with the antitamper screws? then must be removed. and replaced new..

a rare car , and even more one that runs....

here is the online FSM answer

Hi, can you tell if it's the lock in the steering column or something with the power steering instead? If it feels like the power steering, check the belt for looseness and tighten as needed. If it feels like it's in the column, your locking assembly may be coming loose inside. Below is a procedure for removing the steering wheel lock for inspection. Please let me know if you have questions, and thanks for using FixYa.

REMOVAL & INSTALLATION The steering lock/ignition switch/warning buzzer switch assembly is attached to the steering column by special bolts whose heads shear off upon installation. The bolts must be drilled out to remove the assembly or be removed with an appropriate tool. The bolts may also be removed with a hammer and chisel by notching the bolts and tapping them counterclockwise with the hammer and chisel.
The ignition switch or warning switch can be replaced without removing the steering lock assembly. The ignition switch is on the back of the assembly and the warning switch is on the side.

if your key won't work ,the steering wheel has to come off to replace key switch - special tools needed - if the problem is engine not starting or cranking over - the electric switch the key rod goes down to is on the bottom of the steering column above brake pedal

Its usually NOT the lock cylinder on the 470s, its usually the housing. The cylinder is on the dash and points towards the engine. Behind the plastic dash panel (once removed) you will see it in fact sticks in an aluminum tube that goes down 2 or 3 inches, then makes 2 turns, left to attatch to the steering column, and right to attatch to the actual ignition switch. The gear and rod assembly that the cylinder attatches to that allows it to rotate the switch usually shatters in the middle and the key starts freewheeling because there is no longer any attatchment to any of the gears or springs or click points that youd usually feel as the rotational resistance. UNFORTUNATELY this is not a 5 minute job (If it was, cars would be a breeze to steal!). Youll need at least a lock cylinder housing (dealer stock em, they break all the tyme), and IF your cylinder is undamaged, change the housing (it bolts to the steering column and extends from column towards center console area where the ignition SWITCH is actually located). If your cylinder is damaged or the housing is so shredded you cant remove the lock cylinder by normal means...then youll also need the cylinder...and it will have to be recoded to the vehicle so the anti theft will allow the new keys/cylinder to start the car. If your old cylinder and keys are intact, then transfer them to the new housing and car wont even know it happened and should start up and work as normal. Some can be removed intact, some cant...depends on how yours broke.

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.
