The keys slide across the closing table, the moving truck pulls away, and your home is finally yours. But there is one question worth answering before the first night: who else may still have a working key? This new homeowner lock guide puts the first security moves in the right order, so you can protect your doors without guessing what needs attention.

Start With the Keys, Not the Hardware

A house can come with a neat key ring and still have an unknown number of copies in circulation. Previous owners may have given keys to relatives, neighbors, dog walkers, house cleaners, contractors, babysitters, or tenants. A missing spare key can outlast a sale by years.

Rekeying is usually the fastest first move when the existing locks are in good shape. A locksmith changes the internal pin configuration so old keys no longer work, then provides a new set of keys. You keep the existing lock hardware while taking control of access Professionally.

Changing locks is a better call when the hardware is damaged, worn out, low quality, mismatched, or no longer fits your security goals. If a deadbolt sticks, the key must be jiggled, the latch does not extend fully, or the lock shows signs of forced entry, do not treat it as a cosmetic project. Get it inspected and repaired or replaced.

Before any work begins, gather every key you received: front door, back door, side door, garage entry, mailbox, shed, gate, basement, and interior storage areas. A mobile locksmith can assess the lock types on-site and tell you which cylinders can be rekeyed and which ones should be replaced.

New Homeowner Lock Guide: Secure Every Entry Point

Your front door deserves attention, but it is rarely the only way into a house. Walk the property in daylight and look at it from an intruder’s point of view. The goal is simple: identify every opening that reaches the home, garage, valuables, or private areas.

Exterior Doors Need a Deadbolt and a Strong Frame

A deadbolt is only as effective as the door, frame, strike plate, and screws supporting it. Check that the deadbolt extends smoothly into the frame and that the strike plate is secured with long screws that reach solid framing. A loose strike plate or split door jamb can weaken an otherwise dependable lock.

For primary entry doors, choose quality deadbolts designed for exterior use. Grade 1 hardware is generally the strongest residential option, while Grade 2 can be appropriate for many standard homes. The right choice depends on the door construction, neighborhood conditions, number of users, and whether you want electronic access.

Also examine the hinges. On an outward-swinging door, exposed hinge pins should have security features that prevent the door from being lifted off its hinges. A locksmith can recommend the right hardware rather than adding parts that do not fit the door correctly.

Do Not Forget the Garage, Side Door, and Sliding Door

The door between the garage and the home is a major security checkpoint. It should have a reliable deadbolt or locking system, especially because garages often contain tools, bikes, vehicle remotes, and access to the main house. If your garage remote was passed along during the sale, reset the opener and remove any stored remote access you cannot identify.

Side doors and rear doors are often less visible from the street, which makes their locks just as important as the front entry. Treat them as primary exterior doors, not secondary hardware.

Sliding glass doors need separate attention. Confirm that the factory lock engages correctly, then consider a supplemental security bar or professionally installed secondary lock. The track should be clean, the door should not lift easily, and the frame should be in good condition. A lock cannot compensate for a loose or damaged sliding panel.

Decide Whether Smart Locks Fit Your Household

Smart locks are useful when they solve a real access problem. They can let you assign separate codes to family members, remove a code when a contractor’s work is done, and avoid hiding a key under a planter. For busy households, that control can be a major upgrade.

They are not automatic security magic. A smart lock still needs a properly aligned door, a strong deadbolt, secure mounting, and regular battery checks. If the deadbolt binds against the strike plate, adding electronics will not fix the underlying door issue.

Choose a model with a physical key override if you want a backup during a battery failure or technical issue. Decide who will administer the app, keep recovery information secure, and receive low-battery alerts. If you prefer simple, dependable access without an app, a high-quality mechanical deadbolt may be the better fit.

For homes with frequent visitors, caregivers, cleaners, or short-term rental activity, keypad access can reduce key handoffs. Just create individual codes instead of sharing one household code, and remove temporary access as soon as it is no longer needed.

Control Copies and Create a Key Plan

Security is not only about the lock on the door. It is also about knowing who can operate it. Once your locks are rekeyed or replaced, decide how many keys should exist and who has each one.

Avoid leaving labeled spare keys in obvious places. A hidden key may feel convenient, but it creates a predictable weak point. A trusted nearby person can hold a spare, or you can use a secure access solution that matches your household’s needs.

If several exterior doors use different keys, ask about keying them alike. One key for multiple compatible locks can make daily life easier. There is a trade-off: a single lost key affects more than one door. Some homeowners prefer one key for convenience; others choose separate keys for higher separation between areas. The best setup depends on who needs access and how you use the property.

Keep an updated record of gate keys, mailbox keys, garage remotes, keypad codes, and alarm credentials. Store it somewhere private, not on a note by the door or in an unsecured shared message.

Fix Small Door Problems Before They Become Security Problems

A lock that sticks is often a warning that the door has shifted, the frame is swelling, or the strike plate is misaligned. Forcing a key or slamming the door can turn a minor adjustment into a broken key, damaged cylinder, or full lockout.

Pay attention to these signs:

• The key is difficult to insert, turn, or remove.
• The deadbolt will not extend unless you pull or push the door.
• The latch does not catch consistently.
• The lock spins, feels loose, or shows visible damage.
• A door frame has cracks near the strike plate or latch area.

Schedule service before the lock fails completely. Early repair protects your access and gives you time to choose the right hardware instead of making a rushed decision after you are locked out.

Plan for the People Who Need Access

New homes fill up Efficiently with service appointments, deliveries, family visits, renovation crews, and pet care. Do not hand out a permanent key because someone needs access for one afternoon. Use a temporary code when appropriate, meet the person at the property, or arrange a controlled handoff.

If you are renovating, rekey after the last contractor leaves. Even when everyone involved is trustworthy, keys can be misplaced, copied without your knowledge, or passed between crews. This is especially important after changing doors, replacing windows, or completing garage work.

For a larger property, detached garage, home office, or separate guest space, consider whether restricted access makes more sense than one key for everything. A locksmith can help build a simple access plan that gives the right people the right entry points without creating unnecessary copies.

When to Call a Locksmith As scheduled
