I installed it based on the pelican wiki. I had a toolset which included a tool for this that made it really pretty easy. It came as part of the SG Motorsports Dash,Ignition,Lock,Radio Key Removal Tool. The tweasers looking tool.

The key was difficult to insert at first. Very difficult. Almost like it had to be broken in. Now it goes in normally but makes a very loud thunk when I remove it. Is this all normal for this keyset?

The original tumbler had the steering lock extension piece broken off. I can't imagine it was working as intended.
