EASILOK SK4510 Compatibility Guide: Replacing an Adams Rite 4510-Style Deadlatch
EASILOK SK4510 is a mechanical storefront deadlatch keypad lock with an exterior code pad, no key cylinder, and an inside push paddle. It can be screened as a replacement candidate for a compatible Adams Rite 4510-style application, but the name alone does not prove fit. Confirm the lock body, exact backset, door thickness, faceplate, latch, paddle, holes, strike, and frame before ordering.
What the EASILOK SK4510 Is
The SK4510 is a keyless deadlatch with push paddle for compatible narrow-stile storefront-door preparations. The outside mechanical keypad retracts the latch after an authorized code is entered. From inside, the push paddle provides the intended exit-side operating path. Normal mechanical-code operation does not rely on batteries, wiring, Wi-Fi, or an app.
The standard SK4510 has no physical-key cylinder. If a project requires an SFIC core, a facility key system, or a physical-key override, treat that as a separate model-selection question rather than assuming it can be added to SK4510.
SK4510 is a deadlatch product. Do not confuse it with:
- a hookbolt or straight-bolt storefront deadlock;
- a bottom-rail deadbolt;
- an electrified strike or magnetic lock;
- a cylindrical residential keypad lock; or
- a different mortise body hidden behind similar-looking trim.
The lock body and door-edge hardware identify the product family more reliably than the outside keypad shape.
Which Keyless Lock Replaces Adams Rite 4510?
For the search question which keyless lock replaces Adams Rite 4510, EASILOK SK4510 is the relevant product direction only when the existing opening uses a compatible 4510-style deadlatch arrangement and the field evidence matches the selected SK4510 configuration. In other words, it is an Adams Rite 4510 replacement candidate, not a universal drop-in conclusion.
Adams Rite describes the 4510 as a spring-loaded deadlatch that can be retracted from the inside by compatible paddle or handle hardware. That reference helps identify the old lock family. It does not transfer Adams Rite dimensions, materials, certifications, performance claims, or ordering combinations to SK4510.
Identify a 4510-Style Deadlatch Before Measuring
A 4510-style deadlatch normally presents a spring-loaded latchbolt at the door edge. The latch engages a strike on the frame when the door closes, while the inside paddle or handle retracts it for exit. This is different from a deadlock whose hookbolt or straight bolt remains projected until it is deliberately retracted.
Collect these photographs before making a compatibility decision:
- The full outside of the door and trim.
- The full inside, including the push paddle.
- The door edge with the door open.
- The complete faceplate and its screw positions.
- The latchbolt from the front and side.
- The frame strike and the latch-entry opening.
- Any visible manufacturer, model, or backset marking.
- Existing holes and previous modifications, when they can be exposed safely and with authorization.
These views let a reviewer separate the old lock body from the visible keypad or paddle. Start with the storefront lock identification guide if the existing hardware category is not yet clear.
Will SK4510 Fit My Storefront Door?
SK4510 may fit only after every material fit item has been checked. Use the following sequence and record each result as confirmed, not matched, or unknown. An unknown value is not a match.
1. Confirm the lock-body category
Verify that the existing device is a storefront deadlatch rather than a deadlock, bottom-rail lock, flush bolt, or unidentified mortise device. A similar outside plate cannot resolve this question.
2. Measure the exact backset
Backset is measured from the correct door-edge or faceplate reference to the operating centerline defined by the applicable hardware drawing. Do not estimate it from a product photo or measure from an added trim edge.
Current EASILOK catalog information lists these SK4510 backset options as product directions:
- 31/32 inch;
- 1-1/8 inches; and
- 1-1/2 inches.
Confirm that the required size exists in the exact current SKU, finish, and configuration being ordered. Adams Rite's 4510 reference also includes a 7/8-inch backset. Because 7/8 inch and 31/32 inch are different dimensions, never round one to the other or choose the closest fraction.
3. Measure structural door thickness
EASILOK catalog information lists a 1-3/8-inch to 1-3/4-inch door-thickness direction for SK4510. Measure structural face to structural face at the installation area. Do not include removable trim unless the current installation instructions explicitly define it as part of the mounting thickness.
4. Compare the faceplate, body space, and holes
Check faceplate length and width, screw positions, latch opening, lock-body cavity, outside keypad footprint, inside paddle footprint, and all mounting-hole centerlines. Previous drilling, filler plates, reinforcement, repairs, or enlarged cutouts can change what is required even when the original door model is known.
5. Verify the latch and strike together
A deadlatch works as a door-and-frame system. Confirm latch position, projection, movement, frame strike type, opening, alignment, and engagement. A replacement lock cannot by itself correct a sagging door, bent frame, worn hinge, loose strike, or distorted opening.
6. Verify the inside push-paddle arrangement
The confirmed SK4510 configuration includes an inside push paddle. Check the paddle location, clearances, actuator relationship, mounting pattern, direction of operation, and interaction with the latch. The phrase SK4510 push paddle lock describes the intended outside-keypad/inside-paddle arrangement; it does not prove that an old paddle or its holes can be reused.
7. Record handing and site conditions
Record the observation side used to describe door handing, the swing direction, frame condition, nearby glass or reinforcement, and any local egress or accessibility requirements. Do not infer a complete installation configuration from a general “non-handed” marketing phrase.
SK4510 Pre-Order Evidence Checklist
| Check | Evidence to record | Stop or escalate when |
|---|---|---|
| Existing lock type | Door-edge photos, faceplate, latch, old marking | Hardware is not a deadlatch or cannot be identified |
| Backset | Ruler-based measurement with both reference points visible | Reading is unclear, 7/8 inch, or outside a confirmed current SKU |
| Door thickness | Structural face-to-face measurement | Outside the catalog direction or affected by unverified trim |
| Faceplate and body | Dimensions, screws, cavity, latch opening | Body space or faceplate preparation differs |
| Exterior and interior holes | Hole sizes, spacing, centerlines, trim footprints | Drilling, filling, reinforcement, or hidden modification may be required |
| Push paddle | Position, actuator relationship, clearance, movement | Old paddle or connection differs from the intended configuration |
| Strike and frame | Strike type, position, alignment, door movement | Latch rubs, misses, or does not fully engage |
| Exact order | Model, backset, finish, included parts, current instructions | A family name is being used instead of an exact SKU |
Use the storefront lock measurement guide to create a consistent evidence set.
What About SK4510 Code Change Instructions?
Use only the current SK4510 code change instructions supplied for the exact product version. Follow the authorized manual with the door open, then test normal keypad and inside-paddle operation before placing the opening back into service. A missing or mismatched manual should be resolved through EASILOK support with the order and model information.
This compatibility article intentionally does not reproduce internal combination components, decoding methods, bypass steps, or unauthorized-entry instructions. Changing a code also does not prove physical compatibility: backset, holes, latch, paddle, strike, and frame remain separate checks.
When Drill-Free Replacement May Be Possible
A drill-free installation may be possible only when all relevant parts of the existing preparation align with the selected SK4510 configuration:
- the existing device is the correct deadlatch type;
- exact backset and door thickness match;
- lock-body space and faceplate preparation match;
- exterior and interior holes align;
- the latch and push-paddle arrangement match;
- the strike is suitable and correctly positioned; and
- the door and frame are aligned and serviceable.
If one required body position, hole, faceplate, paddle connection, or strike location differs, drilling, filling, reinforcement, adjustment, or professional modification may be required. Do not promise “no drilling” from the 4510 name, exterior appearance, or one measurement.
When SK4510 Is Not Yet the Right Candidate
Pause the selection if:
- the old lock is a hookbolt deadlock, bottom-rail lock, or unidentified device;
- the exact backset does not match a confirmed SK4510 SKU;
- the project requires an SFIC or other physical-key override;
- door thickness is outside the verified direction;
- the faceplate, body cavity, paddle, holes, or strike differ;
- the door or frame is damaged, misaligned, or heavily modified; or
- fire, accessibility, egress, or local-code requirements remain unresolved.
For an uncertain, damaged, modified, or regulated opening, use a qualified locksmith or commercial-door professional. Do not rely on remote photos for a life-safety conclusion.
What to Send for an SK4510 Compatibility Review
Send the outside, inside, door-edge, faceplate, latch, paddle, strike, and model-marking photos; exact backset and door-thickness measurements; required finish; current door and frame condition; and notes about previous holes or repairs. State whether a physical-key override is required. Clear evidence is more useful than “it looks like a 4510.”
Frequently Asked Questions
Is SK4510 compatible with an Adams Rite 4510-style deadlatch?
SK4510 may be a replacement candidate when the existing device is a compatible 4510-style deadlatch and the lock body, exact backset, door thickness, faceplate, interior paddle, strike, holes, and frame preparation all match the selected configuration. The 4510 name or a similar exterior does not confirm fit; measure and compare the opening before ordering or drilling.
Does SK4510 include a push paddle for exit?
Yes. The confirmed SK4510 configuration includes an inside push paddle for exit. Its inclusion does not prove that the lock fits an existing storefront door or that an old paddle can be reused. Verify the paddle position, actuator relationship, mounting holes, clearances, latch movement, strike alignment, exact SKU, and applicable egress requirements for the installation.
