Step 1 - Remove the Old Trim
First you should use your ripping chisel to pry the old trim off the door, you will need to break the old trim rather than attempting to remove the individual nails. You can cover the door with a piece of plywood to protect it from damage during the removal process.
Step 2 - Remove Nails
Any nails that did not come out with the trim can now be removed with a claw hammer or a nail remover. These should come out fairly easily but you need to ensure that you get every single one out.
Step 3 - Measure Up
Now you need to measure the length of the old trim to ensure that you know the dimensions you need to cut the new trim to. Use a miter saw to cut the ends of the new trim at a 45 degree angle.
Step 4 - Dry Fit the Trim
Once you have cut the new trim to size you then need to try it against the door to check that it fits properly. Make sure that you haven't made any mistakes and that the trim fits snugly against the door frame and against the other pieces of trim. If there are any gaps then you can slightly adjust the angles using a sander.
Step 5 - Mount the Trim
The exterior trim now needs to be nailed into place by using finish nails. You will find that this is easier if you're using a nail gun. However, you can also use a hammer to fix these nails in if a gun isn't available. If the trim is very thin then you might need to drill a small pilot hole through the wood to prevent it from spitting when the nail is driven through it. Then use a center punch to drive the head of the nail below the level of the wood.
Step 6 - Finishing Touches
Now you simply need to fill in all of the holes with a wood filler and use a sander to even everything out. The trim can then be painted or stained to match the color of the rest of your house and door.
