Hi helio yes go to immobilizer and hit pcm replacement and follow prompts no pin
code needed. Good luck.

 it works on many vehicles. Honda does not not required to input a code but others do. this tools are not very strong on immobilizer yet, some will do and some don't depending on your region. good luck.

 If all keys was lost just select the option that all keys lost it let you do all new key but if found any old keys it will not start until do add key with new codes you just program to new created to the new key set.

Yes you are correct also, both ways will erase all keys stored in memory and program
the available keys. The reason I advice to do pcm replacement is because its mostly
available instead of all keys lost which had been found to be missing in many vehicles
and people understand what it means but pcm replacement is something some people
don't relate to programming keys, it also works very fast. The only downside to this is
it will also reset the pcm and it will need to re-learn all values but it does it pretty fast
though.

 you're welcome. supertech is right also either option may be used.
