Buying a home is exciting, but the first week after closing is also your most vulnerable period. Realtors, contractors, cleaners, pet sitters, neighbors, and the previous owners may still have working copies of your keys. The simplest way to protect your family and your investment is to rekey every exterior lock as soon as you get the keys. This guide explains why rekeying matters, how it differs from replacing hardware, which doors and locks to prioritize, and what a professional visit looks like from start to finish.

Why rekeying is urgent for new homeowners
Unknown key circulation. Sellers may have shared keys across years of maintenance and deliveries. Even if everyone is honest, copies get lost.
Insurance and liability. After a break-in, adjusters often ask what you did to secure the property. Showing that you rekeyed promptly can support a clean claim history.
Faster and cheaper than replacement. Rekeying changes the internal pins of your cylinders so old keys stop working. You keep your existing hardware and finish the job in a single visit.
Immediate peace of mind. Moving involves dozens of tasks. Rekeying is the one action that reduces risk the moment the locksmith leaves your driveway.
Rekey vs replace: what is best for your house
Choose rekeying when
-
The current hardware is in good shape.
-
You want one-key convenience across front, back, and garage doors.
-
You are on a move-in budget but need security now.
Choose full replacement when
-
Locks are corroded, jammy, or mismatched.
-
You want to upgrade to a heavier deadbolt with a one inch throw and a reinforced strike plate.
-
Storm exposure has warped the door or frame and the bolt does not seat cleanly.
A seasoned technician can mix both in one appointment. For example, rekey functional cylinders and replace any that are rusted, misaligned, or builder grade.
The move-in day lock map
Walk the property with this checklist. Tag each item as rekey or replace.
-
Front entry
Primary deadbolt and latch set. Confirm the deadbolt throws fully and the door meets the frame without forcing. -
Back door and side door
Often neglected. These are common break-in targets because they face yards or alleys. -
Garage man door
The side or rear door that enters the garage is frequently weakest. Upgrade to a solid deadbolt with long screws into the stud. -
Door from garage to kitchen
Treat it like an exterior door. Rekey and ensure the deadbolt throws fully into the reinforced strike. -
Sliding glass doors
Install a track bar and anti lift device. Many factory latches are only partial security. -
Patio, pool, and screen doors
Add keyed levers or padlocked hasps where appropriate to prevent easy entry during backyard access. -
Gates and sheds
Replace with weather resistant padlocks and keyed alike options for easy yard access. -
Mailbox
New keys prevent mail theft and protect sensitive information like bank statements and medical letters. -
Windows that lock with keys
Rekey or standardize where practical, especially on ground floor.
One key for the whole home
Most new owners dislike carrying a thick key ring. During rekeying, ask the locksmith to set one master residential key for all exterior doors plus matching padlocks on gates and sheds. You will still be able to create restricted copies for housekeepers or dog walkers using a secondary key that opens only the back door, for example. This is an easy way to control access without buying high end systems.
What a professional rekey visit looks like
-
Arrival and assessment
The technician confirms IDs, reviews your lock map, and checks alignment so the bolt seats fully under light hand pressure. -
Pinning and keying alike
Cylinders are removed, repinned to your new key code, and tested several times to confirm smooth operation. -
Hardware strengthening
Strike plates are upgraded with three inch stainless screws into the stud. Loose hinges are tightened and non removable hinge pins added where needed. -
Weather and salt protection
Cylinders receive a light PTFE lubricant, which works better than graphite in Florida humidity. -
Key control handoff
You receive labeled primary keys and any restricted copies requested. Expect a written invoice with the new key code stored securely by the provider if you request future service.
Timing and coordination tips
-
Schedule rekeying for the same day you get the keys. It takes one to two hours for a typical single family home.
-
Bundle minor upgrades. Ask for reinforced strike plates, anti lift devices for sliders, and stainless padlocks during the same visit.
-
Plan for future projects. If you will replace a front door later, rekey now and swap that single cylinder to the new door when it is installed.
Common myths new owners believe
Myth 1: A fresh key from the seller is enough.
Key duplication is cheap and fast. You cannot know how many copies exist. Rekeying is the only way to reset the lock.
Myth 2: Smart features are required to be secure.
Strong mechanical deadbolts with reinforced frames are still the backbone of home security. Electronics are optional.
Myth 3: Only the front door matters.
Burglars prefer hidden entry points. Side and garage doors deserve the same attention.
Budgeting and options
A straightforward rekey costs less than replacing multiple locksets. Expect lower pricing per lock as you add more doors in one visit. Combining service on mailbox, gate, and shed padlocks saves time and gives you one key for everything. If you own a townhome or condo, confirm HOA rules about exterior appearance and allowable hardware finishes.
After rekey care
-
Keep a single spare with a trusted neighbor or family member. Avoid obvious hide a key spots.
-
Update your alarm provider and smart lighting schedules. New codes and new routine help the home look occupied.
-
Lubricate locks twice a year. A quick PTFE spray and a simple screw check keep everything smooth through salt season.
-
Rekey again after renovations. If contractors need entry for weeks, change the key code when they finish.
