Locked Steering Wheel And KEY WILL NOT WORK

It does lock but it takes a full revolution.

Disconnect battery , re set computer

Hi
if you're lucky it's just pressure on the steering lock if you put your key in and shake your steering wheel side to side whilst Turning the key

I'm going to answer this question since I don't know how the security system would affect the lock.
If you can get the key out of the lock, you may want to spray some WD40 or other lube in the slot where the key goes.
If that does not help, you should be able to drop the cover from under the steering wheel and disconnect the switch from the lock cylinder.
If the lock is still stuck, it may have damaged tumblers or something may be jammed with the shifter and steering wheel lock.

First thing you need to try is wiggling the steering wheel back and worth while turning the key to try and unlock the steering column. If the key is worn out it may not turn well in the ignition. Another thing is to lubricate the ignition cylinder. If nothing works, it maybe the ignition cylinder tumbler is worn out and needs to be replaced.

this might sound easy but have you turned the wheel enough to take tension off the key mechisium it sometimes puts a lot of preassure on the lock and you cant turn key till you turn steering wheel opposite direction to take preassure off key lock

IF this is the same problem as in the Dodge Caravan's, then put the key in the ignition and tap it with a hammer, big wrench, etc. Not too hard! My caravan does the same thing and I can jam the key in the lock and get it to turn fine. Eventually you will have to replace the igintion lock cylinder.

Try turning the steering wheel (hard) right and left while turning the key. Steering lock , and ignition lock work in conjunction with each other.

wriggle the steering wheel left to right while turning the key!

Have you pushed the button behind the key ? Small button between key and dash must be pushed to remove key.
