1997 GMC Sierra key wont turn?

Question

The key in a 1997 GMC Sierra wouldnt turn so we changed the key cylinder. We followed the instruction that came with it but now the key does not want to come out when you turn the truck to the off position. It kinda feels like it is not going all the way into the off position. Any ideas on what could be causing this? THANKS!!

Answer 1

computer controlled??

my 2004 Evnoy had a dead battery, I tried to start it, but it only clicked.... The headlights are set for daylight running, so they were on. The battery voltage was so low that the computer wouldnot function, but the lights were on and I could not get the key out of the ignition.

SOOOO, have you checked the battery? fuses? fuse links?
