I recommend ordering easily rekeyed locks for all the doors. Then is 4 years down the road you find you want to “change your locks” the whole process is simply buying more keys – no need for a locksmith. You can easily remove your current locks are install the new ones.
There are lots of videos both on the site below and YouTube.

Look at the Support tab for installation and re-keying instructions.
You get a couple of keys. I would keep both those keys in a drawer — use them only to have your daily use key made at HomeDepot/Lowes.
