Removing the lock will allow access to the firing pin, but......just in case you need to remove the hammer, here is what worked for me: disassemble the entire lock, leaving only the hammer and tumbler. Remove the hammer screw, also. Find a suitable pin punch that fits into the hammer screw hole and reaches the bottom. Support the lockplate as close as possible to the tumbler. Insert the punch into the hammer screw hole and apply appropriate force to drive the tumbler downward, using the lockplate as a support for the hammer. I have never had any damage as a result of this process, but, shimstock can be placed under the hammer to prevent scratching. Good Luck!
