I've got a new tumbler and ignition switch. How do I go about getting the old one out?

take off steering wheel
take out the screws holding the wiper/blinker switches in.
remove them...they have wires and hoses connected to them, so unplug all of that.

Then you will see a screw that is holding the key tumbler and ignition switch in...remov e it.
Unplug the ignition switch and pull the assembly out.

If you no longer have the key...you will need to forcibly remove the key tumbler from its location with a slide hammer.

there is a really small screw holding the ignition switch in place...remaove that and wiggle the switch out of the housing.

replace and you removed it.
