It depends entirely on where the key is. If it was inside the house the whole time, your locks are exactly as secure as they were yesterday and nothing needs changing. If the key was lost or stolen, rekeying is the sensible follow-up, because it retires that key for good while keeping your existing hardware. Lock manufacturers give a lost or stolen key as one of the main reasons to rekey, and doing it during the same visit saves a second call.

Look after the lock and the key ages slowly. Keep the cylinder lubricated with the product its maker specifies and free of grit, and have a binding door adjusted, since resistance raises the risk, though a worn, bent or fatigued key can still fail under normal use. Retire copies that have gone thin or kinked instead of straightening them. Cut spares from code, and rotate them so one key is not doing all the work. Take the ring weight off a car key. Small habits, but they add years.

Yes, and they usually should be, because a side door into the garage is the opening most often forgotten and left on an old key. Any pin-tumbler cylinder on the property can be pinned to the house key if its keyway allows: the man-door into the garage, a shed, a keyed gate latch, and many padlocks. A mailbox lock is usually a small cam lock that is replaced rather than repinned. Mention every opening when you book so the right blanks and cylinders are in the van.

For any door people leave the house through, a single cylinder with an inside thumb-turn is the sensible choice, and provincial building rules for dwellings call for exit doors that open from inside without a key. Double-cylinder bolts are keyed on both faces and are sometimes proposed where glass is near the lock, but a captive thumb-turn, laminated glass, or a tested security-film system with its specified attachment, addresses that without a key on the inside.
