What We Offer
Platform identification
Distinguish m3, M4, X4, and other systems before specifying a mechanism or key.
Manipulation resistance
Selected Medeco platforms combine pin elevation and rotation with secondary locking elements.
Product certification
Check the exact cylinder or deadbolt listing rather than assuming every Medeco model has the same rating.
Controlled key supply
Establish the keyway owner and authorization process before ordering replacement keys.
Medeco Upgrades for DC Homes
A Medeco upgrade can involve a complete deadbolt or a compatible replacement cylinder. These are different scopes of work. On an older rowhouse, preserving decorative trim may be possible, but it depends on the actual lock beneath it.
Match the model to the requirement
Selected Medeco platforms use pin elevation and rotation with secondary locking components. Different generations add different key-control features. Do not apply an M4 specification, a UL 437 listing, or a current patent date to every product with a Medeco name. Consult Medeco’s product specifications for the selected hardware.
Hardened components can improve attack resistance; they do not guarantee that a drill bit will shatter or that entry is impossible. Likewise, restricted supply can reduce ordinary copying without proving exactly how many working keys exist.
Keep future access manageable
Record issued keys and retain authorization information. If an original key is missing, address the access it still grants rather than merely ordering another copy. A rekey assessment can determine whether the cylinder can be serviced or should be replaced.
Pair any cylinder upgrade with suitable door reinforcement and normal checks of latch and deadbolt operation.
Hardware Comparison
Rekeying and Replacement: Different Decisions
| Question | Rekey Existing Hardware | Replace Hardware |
|---|---|---|
| Main purpose | Change which key operates a compatible cylinder | Change the lock, its condition, or its function |
| Existing condition | Lock and door should be working properly | Assess wear, damage, fit, and needed repairs |
| Compatibility | Depends on the cylinder and key system | Depends on door preparation and selected model |
| Exit operation | Confirm the current inside operation remains suitable | Confirm the proposed function and applicable exit requirements |
Select hardware for the actual opening. A key-operated inside lock can restrict exit and needs particular care; do not assume a glass panel makes it appropriate.

Common Questions
Medeco Residential Locks in Washington DC FAQs
Are all Medeco locks bump-proof?
No absolute attack guarantee is appropriate. Mechanisms and certifications differ across the product range, and the complete door remains part of the assessment.
Can you copy an existing Medeco key?
The exact platform, keyway, and supplier authorization determine who can provide a duplicate. Provide the key identification and system documents before arranging service.
Can a Medeco cylinder fit my existing lock?
A compatible retrofit cylinder may be available. Match the chassis, dimensions, retaining method, and tailpiece; otherwise a different lock assembly may be required.
What information helps when booking residential locksmith work?
Describe the door and lock, the problem, the Washington DC address, and whether access is affected now. Photos of visible hardware can help identify the next step.
Should I rekey or replace a lock?
Rekeying may suit a compatible lock that works properly when the aim is to change who has a key. Damage, wear, incompatible hardware, or a different function may make replacement more appropriate.
What should I check before buying a replacement lock?
Check the door thickness, existing preparation, lock function, and the manufacturer’s installation requirements. Shared entrances and rental properties may also have owner or building requirements.
Can an arrival time or full price be confirmed from a photo?
A photo can clarify visible hardware, but it may not show internal damage or door and frame conditions. Ask whether an assessment is needed, what it costs, and how the final scope and price will be approved.
What if I am locked out right now?
Call (202) 830-0706 to explain the location and check current availability. If anyone is in immediate danger or there is a medical emergency, call 911 first.
What authorization should I prepare?
Have identification and evidence that you own, occupy, or manage the property. For a shared or rental building, involve the person authorized to approve the work.
Before Work Starts on Your Home
Confirm who may authorize the work, which doors are included, and whether existing keys should stop working. Keep a written record of the hardware and keys supplied.
