If the key will rotate the cylinder then you are OK as far as the "key" goes. The whole point of the key and the key cylinder/housing is to insure that the actual multi prong ignition switch's internal working are not accessible. The key cylinder sits on top of the switch". The bottom of the key cylinder has a dog tooth which matches up to a recess in the ignition switch. When you turn the key, the tooth on the bottom of the key cylinder rotates the ignition "switch" which powers up the car. On older cars like the 9000, if you have the correct key then the car starts; however, if the cylinder has been removed or one has "drilled" the key cylinder meaning the recess of the switch is not covered by the key cylinder a flat head screw driver can be inserted into the switch and the car started without using the key. In this scenario, the screwdriver becomes the "key". Back in the day, this was one of the ways a thief was able to quickly steal an "older" car. In newer cars, where a computer engine imoblizer has been activated, removing the keyed cylinder and accessing the "switch" will, in most cases, not allow the car to be started. More electronic layers of security have followed hence the move to electronic keys.In the 9000's case, once the switch is accessed, I'm pretty sure the car can be started with a flat head screw driver.
When one side loads the key cylinder during a "start" cycle, all that can possibly happen is that the dog tooth acts on the internal part of the ignition switch and brings the contacts within a severely worn out switch close enough to make "contact". While this might save your ass a few times (one time for me), eventually this hack will produce no results.
