1990 Dodge Spirit ignition

Hi, your local autostore may have new lock cylinder? The new lock cylinder comes with ignition key,but, not with door lock or trunk key. The new lock cylinder may come with instructions? I'll look at info. I wanted to add, if there is an airbag, you need to disarm before working around steering column.
The tamper proof screws, you may need a special bit, the national brand autostores sells them.
