I can't get my ignition key out on my Honda Civic. My gear stick is stuck on P but I can roll the car back and forth. Any ideas?

Sounds like shift cable or wires off from linkage. I guess gear position is neutral position but only lever moves.
Is that lever moves lighter than before?

So check all linkage under the shift lever or around T/M area. When transmission gets P position will pull out the key.

Hope it helps.

I do appriciate that, I'll check when I get off work, thanks!
