Nissan Repair: Ignition Key Wont Turn - 2002 Nissan Maxima, uncommon occurance, graphite powder

Question
Parked the car the other night and the key removal felt a little different when I took the key out after putting the auto transmission in Park.  Later that evening I tried to start the car and was unable to get the key to turn in the ignition switch.  Initially the steering wheel was not locked, but in attempting to get the key to turn I eventually locked it.  Still no key turning.  I released the shift lock and move the shift selector through the gears, still no key turn.  Rocked the car, move the car when in neutral, tried wife's key, valet key, graphite powder, many additional pull and pushs to the steering wheel while jiggling/turning the key.  Nothing seems to work which will allow me to turn the key in order to crank the car.  I have scanned the web and see that this is not an uncommon occurance with Nissan vehicles and car companies as well.  What can I do to resolve this issue?  My next step unless I can resolve is to have the car towed to the nearest Nissan dealership for service.  Is issue related to ignition switch, shift linkage, etc.  One other note, I do hear individual clicks within the stearing column when I move the shift lever between Park and the right side of the Park setting (as if shifting into other gears).  Is dealership my best bet?  Any idea on cost too?

Hi Michael -

Gosh you have done all I would have done. It looks like the pins are stuck in the ignition switch and will not engage to turn the ignition to start the car. I can think of 2 things to do:

1. Instead of Graphite, try using WD40. S[ray directly into the lock and GENTLY tap around the switch. I am hoping that the pins find home and set back where you can insert the key.

2. If that doesn't work, remove the plastic shroud around the ignition, and you should be able to remove the lower part of the ignition switch where you can at least start it with a screwdriver. Then get it down to a mechanic to have the key cylinder replaced.

NOTE: If you do not want seprate keys for your door and your ignition, you may purchase the entire lock kit from the dealer, but be ready to spend big bucks. I think the lockset alone runs a few hundred dollars.

Most repair shops can take care of your car, however the part will have to be ordered from the dealer anyway, and sometimes it is a trade off. I would still take it to a competent mechanic, though.

Hope this helps -
