This is not a tutorial but rather my observation during repair.
Symptoms:
Key is difficult to insert; unable to close door with the key (I am sure that my former neighbor's successful ability to use master key contributed to this condition)
A bit of background:
Honda OEM locks are using numbered pins (x1, x2 etc)
During repair, a number from each pin along with its position can be written down so lock will be coded to the original key
Such pins are used starting 2003
You should get at least 3 pins of each type except the very last one (double wide)
A good source of nearly new pins is the wrecking yard; cars with key less entry typically have least worn trunk locks; manual operating locks usually have minimal wear on the passenger side
A lock with good pins should allow easy insertion of the key
After cylinder is popped out, the core must be emptied into the Ziploc bag along with springs
When removing door armrest, try not to damage master switch bezel:

Armrest removed

After removing pushpin, reach inside and pull the lock rod protector toward hinged side of the door

Inside of the door: glass run channel and door latch

Missing screw? No!

Removing key switch from the lock cylinder; sharp flat screwdriver with thin blade works better than Phillips one

I used 90 degree hook to pull the lock cylinder clip; I learned that it is not necessary to remove it completely

A little more down from this position will allow cylinder to come out

Lock is out; left and right cores are interchangeable

Core is out; there are 5 rows; every other row is upside down; the row closest to the key hole uses only one pin, the row closest to the snap ring uses double wide pin (7 thin pins, one double wide)
Now, withdraw the key only far enough to pull one row at the time; use tweezer to pull the pin and dental pick to pull the spring; write down pin number and location. Re-assemble in reverse sequence
I will post additional pictures later

New re-coded lock

Close up of the power window master switch, no recall yet..

long and thin screwdriver fits well into the lock switch screw

Screwdriver handle inserted in place of lock cylinder makes installation of retaining clip a lot easier
