2005 malibu key won't come out of ignition

SOURCE: key stuck in ignition but it will turn, and

you most likely have a bad key switch cylinder assembly. you can try to spray wd40 solvent into the switch before you have the switch replaced,but sometimes it's a switch replacement that repairs the problem. have you inspected your ignition key to look for damage to the key itself? try a spare key to make sure it's the key,and not the key switch. you can also try turning the key while turning the steering wheel at the same time to get the key to work.sometimes the switch locks when parked in a bind,such as on a hill,or against a curb and so on. try this 1st before you have the ignition switch replaced. AAA auto club,if you're a member covers part of the replacement costs for a replacement switch also. you may have coverage through a cell phone also.one more thing to try, if you have a tilt steering column,try to reposition the steering wheel to see if you can get the key to turn. remember never force it enough to break your key off into the switch! thank you for choosing fixya.com!

The key barrel is defective and it will haver to be replaced. Since you will have to force it to make it turn long enough to get it out you should take the car to a repair shop - the risk of breaking something is too great for you to do it.

A common problem is the ignition cylinder and/or the ignition switch. With the buzzing of the relay, i would say all this may be related to the ignition switch. A low voltage supply to any of the circuits that the switch feeds will give strange electrical conditions. If going to replace the ignition switch, then also do the cylinder at the same time. With all things described, sure sounds like the ignition switch. P.S. The locks may be related to the ignition switch problem or not at all. With that said, would suggest looking at the BCM(body control module)It control locks, and also has alot to do with the security system. See picture at bottom of this page of corroded BCM connectors. 4- Passlock Ignition lock

assuming the 2005 model year stil uses viper security systems...the chip in the key carries a magnetic resistance frequency. if the chip is damaged or corroded the frequency will change and wont engage the igntion. you can either get another key made (about 75 dollars) or bypass the ignition lockout feature.
