Are you installing just the switch or just the cylinder?

Remove the trim around the radio by pulling back. Remove the 3 connectors.

From the hole at the radio, remove the key cylinder. With the ignition in the start position, there is a place on the cylinder housing to insert a tool to release the cylinder. It is at the 5:00 position. Slide the ignition cylinder out.
On the opposite side, remove the pass lock sensor connectorAssemble and perform the relearn.
The relearn is performed by turning the key to start then release the key to run. The security light should be flashing. When the light goes out after 12 mins, turn the key off , wait 30 seconds and start the engine.
What kind of tool do I need to release the cylinder and do I push in or what?
A small nail, allen key, small screw driver, anything like that. Push in at the hole.
