Locate the surface for the ignition switch lock cylinder release button (2)
on the plastic ignition switch housing and center punch a location on the
rib (1) approximately 3/8 inch reward (toward the key entry end) from the
cylinder release button.
Carefully drill a pilot hole through the plastic housing with a 1/8-inch
drill bit.
Carefully drill a larger hole at the pilot location, and slightly into the
ignition switch lock cylinder surface to break the release button retaining
spring using a 9/32-inch drill bit.
Remove portions of the broken spring from the hole using a small suitable
tool.
Grasp the ignition switch lock cylinder and remove it from the switch
housing.
Remove any plastic flashing from the drilling operation, and using
compressed air blow out the ignition switch assembly.

be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or
sealant are identified in the service procedure. Do not use paints,
lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces
unless specified. These coatings affect fastener torque and joint clamping
force and may damage the fastener. Use the correct tightening sequence and
specifications when installing fasteners in order to avoid damage to parts
and systems.

I have a similar problem but I assumed it was because of poor key
duplication (I don't have any original keys).  I figured someday I
would take it over to a locksmith shop and ask him about it-- but I
haven't yet.  You might try that before going through the lock
replacement procedure :)
