Ignition switch does not turn on my 2001 c320

I insert the smart key and usually I would get the dash lit and the wheel would slant into driving position. Now, the key goes in and nothing, It will not even turn. I finally get it to turn and the car starts. I have to fight it for about 20 mins. How can I replace the switch, do I need to replace it all?

It is possible the immobilizer ring is defective(thid ring reads the rolling and number codes form the key. Does your central locking work and does the l.e.d. illuminate when the central locking buttons are pushed. The batteries may be weak and if they are they would have to be replaced and the resynchronized. The resynch procedure is probably in your owners manual. The e.i.s. (switch) is a control module and a complicated replacement procedure- it also takes a good 10 days to get parts because they have to reload it with a special key that made for your vehicle only. Try cleaning the lens on the key. It would also be a good idea to have the e.i.s. codes pulled at a dealer or equivalent. if problem persists. If the car will not start. try disconnecting the battery and wait approx. 15 min. sometimes that will give you a couple of starts unless it is just a software issue. I believe after so many starts these switches have to be replaced because the codes are now illogical; basically they do not reset and go back to zero.

I am trying to get my 1985 GMC Vandura 2500 to start, but the steering g wheel is locked and the key won't turn to try and turn it over. What would be a cause of this?

If you vehicle is parked on a slant and the wheels are slightly turned, the pressure from the weight of the car may be forcing you steering wheel to bind. Try tweaking the steering wheel in the same direction that the wheels are turned using your left hand and at the same time try turning the key with your right hand. Tweaking the steering wheel takes the pressure off of the ignition switch. If that doesn't work, try a different key if you have one.

My 2001 PT Cruiser ignition switch will not turn. I have tried moving the steering wheel up and down, moving the steering wheel left to right while trying to turn the ignition on all to no avail. Help.

was the ignition switch getting hard to turn with the key for a while or did this just all of a sudden happen usually the problem has been going of for a while but people just ignore it until it gets to this point,it sounds like the tumblers in the ignition key switch have gone bad and the tumbler assembly needs to be replaced,the new tumbler assembly can keyed to the original key if the key is not worn out.this should be replaced with a new key if it is.

Ignition switch to a 2001 oldsmobile alero will not turn when key is inserted to start vehicle. Steering wheel will not go to a locked position as it should when car is parked and key is removed. Key will...

no there is no lock position for the alero. if the key wont turn the key and or ignition cylinder may be worn out. try jiggling the key as you try to turn it. you may need to replace the ignition switch to repair this. when you do it will need to be programed to the vehicle. hope this helps

1992 chevy pu. 4 wheel drive electrical issue.

the ignition electrical switch (not the key ignition switch) on the bottom of the steering colomn is probably the issue........You can find it by looking under the dash while turning the key you will see a rod moving back and forth. At the bottom of the rod is the switch.
Hope this helps!
