97 Ford Explorer ignition key in ignition won't start

[annienicole]

Okay where I am at is around 20 degree (F) and I tried to go to work this morning and when I had my key in the ignition it would NOT start!!! I have tried everything. I cannot use the blow-dryer method because my car is not parked anywhere near an outlet. I have tried keeping my key warm; I will have it warmed up and as soon as I take it out of the ignition it is cold as ice again. I also tried holding a boiling cup of water near the ignition so the steam could (hopefully) melt any possible ice. I am now out of ideas. Help anyone?!?!

Also, I have tried jiggling the steering wheel because, in the past, the steering wheel has locked up before so that they key couldn't turn.
