Plan the access, not only the lock
Who uses this Brookfield door every day?
A front entrance can serve one household, two units, a caregiver, delivery drivers, employees, or several tenants. Before rekeying or installing new hardware, think through who needs a key or code and which rooms or entrances should stay separate. That short access plan is easier to change on paper than after several cylinders have been completed.
Daily habits matter as well. If everyone lifts the handle before turning the key, pulls the door tight, or avoids one entrance in cold weather, say so. The workaround may point toward alignment, wear, or hardware that no longer suits the way the opening is used. Replacing one visible part without discussing the routine can leave the cause untouched.
At the end, let a regular user try the result. The person who opens that door each morning knows how it felt before. Their quick test can confirm that the new key, repaired latch, or installed lock works without the old trick.
