Ignition barrel release from housing. How to know if it's the lock cylinder or the housing?
I have a bmw e34 ineed to take out the ignition barrel from housing,is there a pin or something to release it I have this issue but switch cannot get to first position. Key turns just enough to unlock steering wheel...if you let go it snaps back to off. It locked up like this a day before and a little wiggling got it past. But now it won't go past, even after oiling key and such. Does this sound like the lock cylinder went bad or the housing? If the latter, how hard is it to remove the housing? (not in the Bentley manual). Thanks!

Remove the ignition lock cover, there is a release button at the end of the lock cylinder, push in with a flat tip screw driver and turn key to the "on" position but don't start car, pull cylinder out with key.
If you need to remove the ignition on a chevrolet silverado then just follow the instructions below. You will also need the following tool unless you can make something similar. The tool is: J 42759 ignition switch connector release tool.
IMPORTANT AS YOUR TAKING THE LOCK OUT OF THE HOUSING MAKE SURE YOU KNOW WHERE THE GEARS ARE LINED UP WRITE IT DOWN OR TAKE PICTURE FOR FUTURE REFERENCE AS YOU NEED TO KNOW THIS TO GET IT BACK TOGETHER.
1. disconect the negative battery lead 2. disable the SIR system Zone 3( you will need to check how to do this as it varies from each year of production. 3. remove the hush and knee bolster (instrument gauges and console) ( you may find away around doing the work above but just take your time ok) 4. remove the steering column trim covers 5. with the key in ignition turn the key to the RUN possition 6. install an allen wrench into the hole on top if the lock cylinder. Push down onto the wrench to release the tab on the lock cylinder inside the cylinder housing 7. slide the lock cylinder out of the cylinder housing. 8. disconnect the passlock and key buzzer from the lock cylinder housing 9. insert tool J 42759 into the lock cylinder housing to release the tabs on the ignition switch. 10. pull the ignition switch out of the lock cylinder housing. 11. disconnect the connector from the ignition switch.
Now for the installation procedure. To install the ignition then follow the instructions below:
1. the gears between the ignition switch and the lock cylinder must be in the correct position, failure to do this will cause the gears to be out of line in the ignition switch and lock cylinder housing witch would result in a no start of engine or even drain the battery, so make sure you get this part right. 2. you need to make sure the gears are lined up correctly if not it wont work correctly if it is wrong you need to turn the gear in the ignition switch until it is in the correct possition 3. use a screwdriver to rotate the lock cylinder housing gear counter clockwise until it hits a stop. 4. connect the ignition switch connector 5. insert the ignition switch into the lock cylinder housing, the tabs on the ignition switch must be lined up correctly in the lock cylinder, make sure this is correct. 6. use a screwdriver to rotate the lock cylinder housing gear clockwise to the start position - allowing it to spring return on its own into the run position, if it dont do this then the chances are you have the lock in the housing the wrong way or gears not set correct. 7. align the lock cylinder and then install the lock cylinder into the lock cylinder housing. 8. connect the pass lock and key buzzer into the lock housing. 9. install the steering column trim covers. 10 install the hush and knee bolster. 11 enable the SIR system 12 connect the negative battery cable 13 try the ignition and make sure it works as it should do
If you are unsure of what is being talked about above then you should either leave this job to a pro or go and get a workshop manual as getting this wrong could result in the car not starting or the battery being drained, either way it would mean you have to do the work all over again
There is a technique for turning the key to the On position and sticking a big paperclip or small drill bit into the hole in the face of the lock cylinder to release the catch so the cylinder will pull out. Works great with a new lock cylinder. Almost impossible with a 15 year old lock cylinder.
Most of us end up removing and replacing the whole housing.
A dremel tool works well to cut slots in the security bolts on top of the steering column. Then a short straight blade screwdriver bit turned with a small ratcheting box end wrench is the easiest way to unscrew them.
You will probably want a new key to go with your new lock because the key is probably pretty worn as well.
When you pull off your steering wheel, be careful not to damage the clock spring connection for the air bag, and note carefully the orientation and position of the two bushings. They are easy to put back wrong and if you do, the steering wheel will rub.
Be sure to lube your steering shaft bearings while you have the housing off.
A short piece of 3/4" PVC pipe pressed down by the steering shaft nut is the best way to put the snap ring back in its notch in the steering shaft
This is a big bucks repair. Many of us have felt your pain. I have done one of my e36s and the other will probably need it some day soon.

had this problem myself recently and i had to remove steering wheel and side covers remove shear bolts from lock housing using a smal chisel that lets you lake of lock housing and steering lock to replace them your local bm dealer should be able to order the correct one to fit your key, your car will still run with key out but you have to insert it to start it.
next to the key hole there is a spot to put in a paper clip. there is a special tool that is a bit more rugged. the key has to be in the 1st position (not off). this can be really tricky and sometimes we can work for hours trying to get a lock cylinder out.Your best bet is to find something that more rugged than a paper clip and stick with it, can be really frustrating
