Can I Get My Locks Changed for Free? What Renters and New Buyers Should Know

In New York State, landlords have a legal obligation to provide tenants with a secure dwelling, and in many cases that extends to lock changes between tenancies. If you are moving into a rental in the Scarsdale area and the landlord cannot confirm the locks were changed after the last occupant left, you have legitimate grounds to request a rekey or full lock replacement before you move in. This is especially true if you are moving into a unit where the previous tenant left under difficult circumstances — a dispute, an eviction, or a domestic situation. Put your request in writing and reference your lease's quiet-enjoyment clause. Many landlords will arrange a professional mortise lock service or a rekey at no cost to you simply to avoid liability.

If your landlord refuses and you're asking yourself 'can I change the lock on my apartment' or 'can I change my apartment door lock' on your own, proceed carefully. Most standard leases require written landlord consent before a tenant modifies any lock hardware. You can typically negotiate this: offer to pay for the work, provide the landlord a copy of the new key, and get the agreement in writing. Installing a higher-grade mortise lock — the type with a full bolt-and-latch assembly set into the door edge that is standard on most New York apartment doors — is often something a landlord will approve because it improves their property. Never force or damage existing hardware; that creates liability that falls entirely on you.

Yes — in specific circumstances. Homeowners and renters insurance policies frequently include a lock-replacement benefit triggered by a covered event: a break-in attempt, a confirmed theft of your keys, or vandalism to the door hardware. Review your declarations page under 'additional coverages' or 'lock replacement.' If a covered loss occurred, your insurer may reimburse a professional mortise lock replacement or emergency locksmith call-out, sometimes with no deductible applied because the claim amount is low. Document everything — photograph the damaged hardware, file a police report if keys were stolen, and keep your locksmith's itemized invoice.

Beyond insurance, certain county and municipal programs in Westchester offer security-upgrade assistance to income-eligible homeowners and seniors. The Westchester County Office for the Aging, for example, has historically connected residents with home-security improvement resources. It is worth a direct call to your local housing office to ask whether door-lock upgrades qualify. Victims of domestic violence in New York have additional statutory protections: a landlord must change locks promptly upon a tenant's written request accompanied by an order of protection or a domestic-incident report, at the landlord's expense. If you are in that situation, you do not have to wait, negotiate, or pay — call a qualified emergency locksmith to perform the work and present the invoice to your landlord for reimbursement.

New homebuyers almost always pay for their own lock changes, and that is entirely reasonable — you simply do not know how many copies of the existing keys are floating around from the previous owner, their contractors, their dog-walker, or the real estate agents who toured the property. A professional rekey or full mortise lock replacement right after closing is one of the most cost-effective security steps you can take. The same logic applies after any change in who has access to your home: a breakup, a roommate moving out, a contractor who had a temporary key, or a lost key set. Speaking of which — yes, a skilled locksmith can rekey a lock without the original key. It requires disassembling the cylinder and manually reading or replacing the pins, so the job is more involved than a standard rekey, but it is entirely routine for an experienced professional. Do not let anyone tell you the whole lock must be replaced just because a key is missing; often a rekey suffices.

What actually determines what you'll pay? Four main factors: the type of lock hardware involved (a basic door knob lock costs less to service than a high-security mortise lock with an anti-pick cylinder), the time of day (a 2 a.m. emergency locksmith call carries different labor considerations than a scheduled afternoon appointment), travel distance within the Scarsdale area, and whether new parts — cylinders, pins, strike plates, or a full lock body — are needed. At Scarsdale Locksmiths, we confirm an exact up-front price before any work begins, so there are no surprises on the invoice. If you have found yourself locked out tonight and you're wondering 'what do I do if I get locked out of my house' — check for a spare key with a trusted neighbor, try an unlocked secondary entrance, then call a professional rather than attempting to force entry yourself. Call us at (914) 344-5259 and we'll be there around the clock.

Not all lock changes are the same job, and understanding your hardware helps you have a smarter conversation with your locksmith. A mortise lock is the rectangular assembly installed inside a pocket (the 'mortise') cut into the door edge — common on older Scarsdale homes, pre-war apartment buildings, and any door where you see a large faceplate on the edge and a separate knob or lever above a deadbolt. Mortise locks are more secure than cylindrical locks by design, but they require a trained hand to service properly: the wrong cylinder or an imprecise fit compromises the very security advantage you are paying for. A door knob lock (or cylindrical lock) is the simpler round-bore assembly found on most modern interior and exterior residential doors — faster to rekey, lower parts cost, but also less robust against forced entry without an accompanying deadbolt.

Mailbox locks are a separate category entirely. If you are asking 'can I change the lock on my mailbox,' the answer depends on who owns it. A privately owned residential mailbox can typically be rekeyed or have its lock replaced by the homeowner — it is a simple cam-lock swap that takes minutes for a professional. USPS cluster mailboxes in apartment buildings or condos are federal property; only a postal carrier or approved technician can service those locks, so contact your local post office rather than a locksmith for that specific unit. For privately owned mailboxes at homes throughout Scarsdale, our team handles replacements as part of a broader property security visit.

Here is a practical sequence: If you just got your keys to a new place — whether on Chase Road, near Scarsdale High School, or anywhere in the surrounding Westchester communities — start by inventorying every lock on the property: front door, back door, side entry, garage entry door, any outbuildings, and your mailbox. Identify whether each is a mortise lock, a cylindrical lock, or a padlock. Note which look worn, which have visible damage to the keyway, and which you simply do not have a key for. Then contact your landlord or review your closing documents to establish who last changed the locks and when.

For renters, send that written request for a rekey to your landlord before you move furniture in. For buyers, schedule a professional mortise lock service for the first week of ownership — pairing it with fresh strike plates and longer security screws is a meaningful upgrade that does not require new lock bodies. If a lockout happens at any point in this process — you are standing on your porch at midnight having just moved the last box in and the door swung shut — do not attempt improvised entry methods that can damage the door or the lock. Instead, check every window and secondary door first, confirm whether a family member has a spare, and if you are stuck, call (914) 344-5259.
