today i went to get some brake fluid and when i turned my car off and pulled out the key only half of it came out! i didn't even feel any tension like it was breaking! anyways tomorrow i'm going to try to acll a locksmith or something. do u think i'll have to get the whole ignition replaced? holy hell this sucks............

 

sometimes they can take the lock/ignition switch apart and get the part of the key out.. other times they can't.

This is part of the reason I invested in a keyless entry. after breaking a few keys off in frozen locks, I decided it was better to pay $300 for an alarm over calling a locksmith to fix my lock twice a year at $100/key.
now I just push a button and my doors unlock and my trunk opens..
that saves me probably 10-15 "uses" of my key each day.. this of how much longer that key will last if you don't have to use it as much.

 

my dumbass brother broke my key off in my drivers side door once.. cost me about 5 bucks to get the guy at AAA lock and key to "fish" the other half out of the lock, then he just made me another one for 3 bucks from my spare that i always keep on me.. maybe in this case, the other chalf can also be "fished" out if the ignition lock??
