Hey Hippy,
Don't worry about the door strip. The lock is actually removed from the inside of the door, not the door strip. Don't even bother removing it because it won't help you one bit. You'll need to remove the inner door panel. As you may know, the door panel is held in by three screws (philips head). One on the top of the door handle (remove that rubber plug), and two underneath the door handle.
Once you've removed that, then you can remove the door handle cover. The lock button needs to be removed first. Unlock it so that most of the red is showing and then pull as hard as you can from the end of it. Basically, it snaps onto a metal rod, so you want to break it free from the metal rod. Once the lock button is off, it should expose a metal rod behind it. Open your door and push it in to lock it.
Then remove that little Fiero emblem using a small fine flat head screw driver. (the one on the door handle plate). You will then expose a small philips head screw. It's foggy here for me, but I believe there is still another screw... maybe behind the door handle? There might be a panel that comes off... it's been a while since I've done it, but I could be mixing that up with my Porsche or my Volkswagen Bus.
Either way, once you've removed the screws holding it in, you remove the door handle plate by sliding it to the front of the car while pulling it outwards as well (like at an angle). The door handle should slide through it and you will then have removed it. You may also need to unplug the wiring for your door lock buttons if you have electric locks (they just pull off... you can pry them off with a flat head screw driver). You may also need to remove the manual mirror adjuster if you don't have power mirrors. It's a small allen key which is used to loosen the ball control (slides out through the bottom when free). Also, if you have crank windows, you'll need to remove the crank window handle as well (there is a special $4.95 tool at the local auto parts stores to remove it).
Now you can remove the door panel. It's just held in by clips. The door panel is hard card-board, so be careful when you remove it.
Once you have the door open, you should be able to see the lock. There is a circlip or something that holds it in place. Once you remove that clip, it basically just slides right out and you can replace it with a different one (not too difficult).
Oh yeah, you'll want to have the window up when you do this.
