Common Problems With Moving Into a New Home
Common problems with moving into a new home extend well beyond unpacking boxes and forwarding mail — many new residents discover too late that the locks, keys, and access hardware on their property carry hidden risks from previous occupants, contractors, and real estate agents. Understanding these challenges before or immediately after move-in allows homeowners and renters to address them methodically rather than reactively, often at lower cost and with far less disruption to daily life.
Common Problems With Moving Into a New Home Overview
A residential property changes hands through a chain of people — sellers, buyers, real estate agents, stagers, inspectors, movers, and contractors — each of whom may have received a physical key or learned an access code. By the time a new resident receives the keys at closing or lease signing, the exact number of key copies in circulation is almost never known. This is not a rare edge case; it is the standard condition of any property that has been occupied before.
Beyond key duplication, hardware itself degrades. Locks that worked reliably for a previous occupant may be near the end of their functional lifespan. Deadbolts can develop internal wear that causes intermittent binding. Knob sets on interior and exterior doors may have loose strike plates or misaligned bolts. Smart locks left by prior residents may still be paired to unknown devices or retain old access codes that were never deleted. These conditions are easy to overlook during a walkthrough focused on paint colors and appliance operation.
New construction presents its own version of the same problem. Builder-grade locks are commonly keyed alike across multiple units in a development during construction so that subcontractors can move freely between worksites. Unless the builder formally rekeyed each unit before handover — a step that is not universally performed — multiple households in the same neighborhood may share the same key cut. Verifying this directly with the builder, and then rekeying regardless of the answer, is the reliable approach.
Key Factors in New Home Security Challenges
The number of entry points requiring attention is usually larger than new residents expect. A typical single-family home has a front door, one or more rear or side doors, a door from an attached garage into the living space, and potentially a basement entry. Each of these points needs a functioning, properly secured lock. In properties with detached garages, sheds, or gated yards, the scope widens further. A partial approach — rekeying only the front door, for instance — leaves meaningful vulnerabilities in place.
Lock grade is a factor that rarely receives attention at move-in, yet it determines how much resistance the hardware provides against forced entry and picking. Residential locks are graded by ANSI/BHMA on a scale from Grade 1 (commercial-duty) to Grade 3 (light residential). Many homes, particularly older ones or those at lower price points, are equipped with Grade 3 hardware that offers minimal resistance. Moving into a new home is a natural moment to evaluate whether the installed hardware meets the resident’s security expectations, since the locks will need service anyway.
Key control is another dimension that matters in rental situations specifically. Landlords in most jurisdictions are legally required to provide a new tenant with locks that cannot be accessed by prior tenants, though the specific obligation varies by state and province. Tenants who are uncertain about their landlord’s compliance have the right to request documentation of rekeying and, in many jurisdictions, the right to have locks changed at their own expense if the landlord fails to act. Knowing this before signing a lease avoids a common point of friction.
Electronic access control introduces a different category of problems. Keypad locks, smart locks, and garage door systems all retain programmed codes and paired devices until someone actively clears them. A new resident who resets only the door code but does not unpair the previous owner’s smartphone application may still leave a functional access pathway open. Factory-resetting smart lock hardware and reconfiguring it from scratch is the correct procedure, not simply overwriting a single code.
Costs and Risks of Inaction
The financial exposure from failing to address lock security at move-in is significant relative to the cost of prevention. A residential burglary results in an average loss of several thousand dollars in property, not counting the costs of repair, replacement of damaged hardware, and the time required to file insurance claims and recover normalcy. Homeowner’s and renter’s insurance policies do cover theft, but deductibles often run $500 to $2,500, meaning that small to moderate losses are absorbed directly by the resident.
Rekeying a single lock cylinder averages approximately $20 to $50 in parts and labor when performed by a mobile locksmith during a single visit. A full home rekey covering four to six entry points typically runs $100 to $200 in total, depending on the lock hardware present and regional labor rates. Upgrading to Grade 1 deadbolts where Grade 3 hardware currently exists adds incremental hardware cost but produces a measurable increase in resistance to forced entry. By any comparison, these costs are minor relative to the losses they help prevent.

Beyond financial risk, there is the less quantifiable cost of uncertainty. Knowing that the access to one’s home is fully controlled — that no unknown key copies exist and no uncleared smart lock pairings remain — contributes directly to the sense of security that makes a new residence feel like home. Residents who defer this work often find that the uncertainty itself becomes a persistent source of low-level stress that persists for months after move-in.
When to Call a Locksmith
Rekeying your locks is a smart move after moving into a new home, and the right time to schedule that service is before or on the first night of occupancy. A mobile locksmith can perform a full rekey of residential cylinders in one visit, working from the existing hardware and producing a new key that renders all previous copies inoperable. This does not require replacing the locks themselves in most cases — rekeying changes the internal pin configuration of the cylinder at a fraction of the cost of full hardware replacement.
There are circumstances where full lock replacement is the more appropriate response. If existing hardware shows visible damage — a strike plate that has been forced, a deadbolt that binds or fails to throw fully, a knob set with a loose or spinning mechanism — rekeying a damaged cylinder does not resolve the underlying mechanical problem. A locksmith can assess the hardware on-site and advise whether the existing locks are worth rekeying or whether replacement is the more cost-effective long-term choice.
Smart lock issues specifically warrant professional involvement when factory reset procedures are unclear or when the previous owner or tenant is unresponsive and cannot confirm that pairings and codes have been cleared. A locksmith experienced with electronic access hardware can perform resets, reconfigure the device, and verify that no residual access pathways remain. This is particularly important in high-density housing situations — condominiums and apartment buildings — where shared building access systems may also be involved.
Homeowners who discover that their garage door opener uses an older fixed-code system rather than modern rolling-code technology should consult a locksmith or security professional about upgrading the receiver. Fixed-code garage systems can be compromised with inexpensive equipment available to the general public. This is a less commonly discussed vulnerability that new homeowners in older properties regularly encounter without recognizing it as a risk.
Recommended Next Steps for New Residents
A practical move-in security checklist begins with a physical inventory of every entry point on the property. This means walking the entire perimeter — including basement windows, storm doors with separate locks, and any outbuildings — and noting the hardware type, condition, and apparent age at each point. This inventory takes less than thirty minutes and produces a clear picture of what needs attention before a locksmith is called, allowing for a more efficient and accurate service visit.
After the inventory, residents should collect all keys received at closing or lease signing and account for their origin. Keys that came from the real estate agent’s lockbox should be noted specifically, since lockbox keys by definition circulated through multiple hands. Any uncertainty about how many copies exist is itself a reason to rekey. If a previous owner provides keys directly and represents that no copies were made, that representation is not independently verifiable — the correct response is still to rekey.
For properties with smart locks or keypad entry, the next step is a full factory reset of each device followed by fresh configuration using the new resident’s own credentials. Manufacturer reset procedures vary by brand and model; most are documented in the device manual or on the manufacturer’s support website. If documentation is unavailable and the device is several years old, replacement with current hardware is often more practical than attempting to troubleshoot an older system of uncertain provenance.
Finally, new residents should establish a habit of periodic lock inspection on an annual basis. Residential lock hardware that receives daily use develops wear over time, and strike plate screws loosen with repeated door use. A short inspection — checking that deadbolts throw fully, that strike plates are firmly anchored with long screws reaching the door frame stud, and that no visible damage has developed — takes minutes and catches problems before they become emergencies. This is particularly relevant in climates where seasonal temperature changes cause door frames to shift, a common cause of intermittent lock binding.
