For security reasons you will have to drill out the original break off bolts and install new ones with the new ignition switch. they dont make it easy without a key..

the original key is coded to your car.
So changing the barrel to have a new key wont help and ill tell you why.
Inside the original key is a transponder chip that is programmed to the cars immobiliser unit.
Attached to the ignition barrel is whats called a reader coil and its job is to read the keys chip when inserted in the barrel to deactivate the immobiliser so that the car will start.
What you need to do is contact a good knowlegable locksmith to provide a new key and code it to your car

clutch sensor at the clutch pedal

Generally speaking, you have a chip in the key that is read by the security system. If the system does not "see" the right chip, the system locks out the ignition and fuel systems.
The new key probably does not have a chip or the wrong chip.

A key code is stamped on the lock cylinder to aid in replacing lost keys.

make sure there's not release button first.
turn the key all the way back and forth (without starting it)
wiggle the key rapidly while trying to slowly pull the key out.

once you get it out try putting some graphite power in there and working it back and forth

the ignition keys are not coded. no "chip" in them you should be able to just have a spare key cut and it will work fine. These use an electronic device in key cylinder that senses the proper rotation of cylinder and tumblers. so if someone tries to pry on with a screwdriver it will disable starter. when this is replaced it has to be reprogrammed
