Maryland law on lock changes during eviction
In Maryland, a landlord cannot unilaterally change the locks on a tenant's unit before obtaining a court-ordered eviction judgment and completing the legal eviction process. Changing locks before this process is complete — regardless of the reason the tenant is being evicted — constitutes an illegal lockout and exposes the landlord to civil liability including the tenant's costs for alternative housing and attorney fees.
The legal eviction process in Maryland requires: filing a complaint in District Court, attending a hearing, obtaining a judgment for possession, and then having the Sheriff execute the warrant of restitution. Only after the Sheriff's execution can the landlord take possession and change locks. The exact timeline varies by county and reason for eviction — non-payment typically moves faster than other grounds.
When a locksmith can legally change locks at a landlord's request
A locksmith can change locks at a landlord's request on a vacant unit — one where the tenant has physically vacated and the tenancy has legally ended. Documenting that the unit is vacant (photos, written notice to the landlord) is standard practice for locksmith companies when a property manager calls for a lock change on an occupied address.
After a successful court eviction with a Sheriff's execution, a locksmith changes locks as part of the normal turnover process — same as any other tenant vacancy. The landlord should have the court documentation available and the locksmith may ask to see it, particularly for units in occupied multi-family buildings where adjacent tenants are present.
The rekeying strategy for tenant turnover
Standard practice for responsible property managers in Maryland is to rekey or replace the cylinder on every unit at every tenant turnover — regardless of whether the previous tenant returned all keys. This eliminates the unknown-copies problem and provides documentation that the access control was reset for the incoming tenant.
For multi-unit buildings, scheduling a locksmith for a batch rekey after several units turn over in the same week reduces the per-unit cost through volume. Coordinating a single truck roll for several consecutive unit turnovers in the same ZIP cluster keeps drive time shared across invoices and preserves consistent pinning charts for master-key plans.
Sheriff execution, writs, and the moment locks may change
Maryland landlords should treat the warrant of restitution as the bright line: until the Sheriff completes execution and the tenant’s lawful possession ends, the unit is not yours to secure unilaterally. After execution, document the date and officer identifier on your turnover checklist so every vendor — cleaning, locksmith, maintenance — can see the lawful basis for access.
If a tenant surrenders keys early, that does not automatically waive remaining possession rights; written settlement language reviewed by counsel is the safe path. Locksmiths who serve multifamily portfolios learn to read redacted court summaries or property-manager attestations so they are not pulled into constructive eviction scenarios.
Documentation locksmiths expect on occupied buildings
Expect to show a government-issued ID matching the management agreement, a work order referencing the court case number when relevant, and photos proving vacancy when you claim abandonment. For occupied hallways, many operators also require a witness from building staff to confirm the unit number before cores are swapped.
Keeping a digital folder per case — complaint, judgment, warrant, Sheriff receipt — speeds the dispatch call and prevents last-minute cancellations when the technician arrives without paperwork.
Cost planning for lawful turnover rekeys
Budget for cylinder swaps on both primary and secondary doors when master-key systems are involved; partial rekeys that leave old sub-masters circulating can void an entire pinning schedule. After lawful possession returns to the landlord, same-day rekey plus restricted keyway upgrades are common because they reset liability before new marketing photos are taken.
Practical recommendations for landlords and property managers
Property managers who operate multiple units in Montgomery County, Prince George's County, and the broader Silver Spring area should establish a standing relationship with a licensed locksmith for tenant turnover work. Having a locksmith on call who understands Maryland's legal framework reduces the risk of inadvertent illegal lockouts and ensures turnover rekeying happens on a predictable schedule.
Document every lock change with a written work order, the date of service, the address, and the unit. This record serves two purposes: it confirms the incoming tenant received a fresh key set with no prior copies in circulation, and it provides evidence that standard access-control protocols were followed in the event of a future dispute.
- Court order first — do not schedule a locksmith until the Sheriff has executed the warrant of restitution
- Document all lock changes with written work orders — date, address, unit number, and technician name
- Rekey at every tenant turnover regardless of key return — eliminates unknown-copies liability
- Maintain a standing locksmith relationship familiar with Maryland landlord-tenant law
Frequently asked questions
Can I change the locks if the tenant abandoned the property?
Abandonment in Maryland requires specific documentation — written notice to the tenant at a known address and a defined waiting period. The legal definition of abandonment is stricter than common understanding. Consult a Maryland landlord-tenant attorney before treating any occupied unit as abandoned; the consequences of error are significant.
What if the tenant changed the locks without permission?
A tenant changing locks without landlord permission is a lease violation in Maryland, but the landlord's remedy is through the lease enforcement process — not unilateral re-entry without notice. Give written notice of the violation, request access, and if access is refused, apply through the appropriate legal process. Do not force entry.
Does a licensed locksmith need to see eviction paperwork before changing locks?
Responsible locksmith companies ask for documentation on occupied addresses. Field teams typically request confirmation of the Sheriff's warrant execution before performing a lock change on any unit that may still contain a tenant's belongings. This protects the landlord from inadvertently ordering an illegal lockout and protects the vendor from participating in one.
Can a landlord rekey between judgment and Sheriff execution?
Generally no — the tenant retains lawful possession until the warrant is executed. Rekeying early can convert a lawful case into a wrongful lockout claim even if rent is unpaid. Wait for the Sheriff's timeline, then schedule locksmiths immediately after lawful possession returns so the unit can be secured before personal property disputes escalate.
