I insert key into steering column,it will not turn. Feels as if its locked. This happened on several occasions last year.but after a few tries the ignition would turn. tonight it will not budge. Ihave a 2003 cadillac deville.
Curious, i've seen this before but not whith this kind of car. if you park with the steering wheel turned to one side or the other, when you shut the car off, the power steering also shuts off. this could be putting pressure on the steering wheel when it locks off. next time, before turning off the motor, aim the wheels straight ahead first. be sure the steering wheel is straight on before you turn the engine off. this time, when you turn the motor off, the power steering will not be a factor. hopefully it eliminate the problem.

you most likely have a bad key switch cylinder assembly. you can try to spray wd40 solvent into the switch before you have the switch replaced,but sometimes it's a switch replacement that repairs the problem. have you inspected your ignition key to look for damage to the key itself? try a spare key to make sure it's the key,and not the key switch. you can also try turning the key while turning the steering wheel at the same time to get the key to work.sometimes the switch locks when parked in a bind,such as on a hill,or against a curb and so on. try this 1st before you have the ignition switch replaced. AAA auto club,if you're a member covers part of the replacement costs for a replacement switch also. you may have coverage through a cell phone also.one more thing to try, if you have a tilt steering column,try to reposition the steering wheel to see if you can get the key to turn. remember never force it enough to break your key off into the switch! thank you for choosing fixya.com!
Sounds like the ignition switch has gone kaput. The ignition switch come in two pieces, an electrical switch and a mechanical switch.
The switch electrical portion can be replaced separatly from the mechanical portion (tumbler that the key engages). It is not a real difficult repair but requires some mechanical knowlege of how the column is assembled.
This can be verified with electrical test equipment prior to buying a new electrical switch.
The ignition key cylinder in a Buick
unlocks the ignition and allows the Buick's engine to start. The
cylinder contains a switch on the end of it (inside the cylinder) that
sends an electric signal to the starter motor. When the ignition key
cylinder fails, the Buick won't start. When this happens, you'll need a
new ignition cylinder. Purchase replacement cylinders from Buick. Difficulty: Moderately Easy
Things You'll Need:
Remove the screws on the bottom of the steering column on
your Buick. These screws hold the steering column cover on. You may need
to tilt the steering wheel to its highest position to access these
Turn the ignition key to the "II" position in the ignition cylinder.
Slide the punch pin into the access slot on the bottom of the ignition cylinder.
Push the pin all the way into the access slot while you pull the ignition cylinder out of the steering column.
Insert the new ignition cylinder into the steering column with the key in the "II" position on the cylinder.
Push the cylinder into the column until it "clicks," indicating that it is locked into the column.
On tilt columns, remove the upper extension shroud by unsnapping the shroud from the retaining clip at the 9 o'clock position.
Remove the trim shroud halves.
Unplug the wire connector at the key warning switch.
Place the shift lever in PARK and turn the key to ON .
Place a 1⁄8 in. (3mm) wire pin in the hole in the casting surrounding the lock cylinder and depress the retaining pin while pulling out on the cylinder.
When installing the cylinder, turn the lock cylinder to the RUN position and depress the retaining pin, then insert the lock cylinder into its housing in the flange casting. Assure that the cylinder is fully seated and aligned in the interlocking washer before turning the key to the OFF position. This will allow the cylinder retaining pin to extend into the cylinder cast housing hole.
The remainder of installation is the reverse of removal.
either you have the wrong key,or try turning the steering wheel to the right all the way,then turn key,this usually happens when you park the vehicle and the wheels are turned,then the steering wheel locks hard
try this take the steering wheel and turn it slightly to the right or left and turn the key at the same time. repeat several times. sometimes the locking detente in the steering column either sticks or gets jammed. this should solve the problem. please rate this....thanks
