Will a Lockin Smart Lock Fit a Standard Single-Cylinder Deadbolt Without New Drilling?

Learn when a Lockin smart lock can reuse a standard single-cylinder deadbolt’s existing holes, which measurements matter, and when to stop and ask support.

Usually, a Lockin smart lock can use the existing holes in a standard US single-cylinder deadbolt installation—but “standard” is only a starting point, not a fit guarantee. You still need to match the exact Lockin model to your door thickness, crossbore, backset, edge bore, latch faceplate, and surrounding clearance.

Lockin’s current Veno Go product page explicitly says it fits most standard US doors with no drilling required. Other Veno models also use existing deadbolt preparation when the measurements and hardware match. If your door fails one of those checks, do not enlarge a hole or force the lock into place; choose a compatible model or ask Lockin support to review the measurements and photos first.

What “without new drilling” means

For this question, no new drilling means reusing the door’s existing deadbolt preparation. It does not mean that the installation is an interior-only retrofit, that the original deadbolt remains in place, or that every lock in the Veno family fits every door.

Most Lockin Veno installations are a replacement for the existing deadbolt assembly. You remove the current exterior and interior deadbolt parts, keep the door and its existing openings, and install the Lockin hardware if the preparation is compatible. The latch and strike still need to align, and the deadbolt must move freely when the door is closed.

That distinction matters for renters and for doors with unusual hardware. Confirm the owner or property manager’s permission before removing the existing lock, and keep the original parts together if the installation must be reversed later.

The five checks to make before you order

Measure the door and opening before choosing a model. Product pages and the Veno Series Door Preparation Guide should be treated as model-specific evidence, not as a promise that one measurement set applies to every Veno lock.

Check What to measure or inspect Why it matters
Door thickness The thickness of the door itself; many Veno preparations are listed around 35–55 mm The mounting hardware must span the door correctly
Crossbore The large hole through the face of the door; Veno preparation materials show 38 mm and 54 mm options The exterior and interior assemblies must line up with the opening
Backset The distance from the door edge to the center of the crossbore; common listed values are 60 or 70 mm The latch must reach the strike at the correct distance
Edge bore and latch The smaller edge opening and whether the latch face is rectangular A rounded or otherwise different opening may not accept the supplied latch without approved work
Clearance Space around the lock, nearby trim, lever, glass, door stop, and frame The reader, housing, and moving parts need room to operate

Measure in millimeters where possible, photograph both sides of the door, and record the current deadbolt brand or model. A photo is especially useful when the edge bore, faceplate, trim, or door stop is hard to describe.

How the current Veno models differ

The answer depends on which Lockin smart lock you mean.

Veno Go

Veno Go is the clearest fit for the “no new drilling” question: its current product page says it fits most standard US doors and requires no drilling. That wording still contains an important condition—“most,” not “all.” Confirm the measurements and latch shape before treating your door as compatible.

Veno

The Veno smart deadbolt uses the same general door-preparation checks: thickness, crossbore, backset, edge bore, latch, and handle clearance. Reusing holes is possible when those checks match the current product and installation materials.

Veno Plus and Veno Pro

The current Veno Plus and Veno Pro product pages list a wooden door, single-cylinder deadbolt, 35–55 mm door thickness, a 54 mm crossbore, 60/70 mm backset, and a 25.4 mm edge bore with a rectangular latch faceplate. They also identify mortise and storm-door setups as exclusions for these video models.

There is a documentation boundary worth taking seriously: the linked quick-start guides depict both 38 mm and 54 mm crossbore diagrams, while the current product pages specify 54 mm for Veno Plus and Veno Pro. If your door has a 38 mm crossbore and you are considering either video model, do not assume the guide drawing overrides the product page. Send Lockin the exact model, measurements, and photos before ordering.

Veno Solar Palm and Veno Solar Face

The Solar Palm and Solar Face pages list 35–55 mm thickness, 38/54 mm crossbore options, 60/70 mm backset, a 25.4 mm edge bore, and clearance requirements around the door and frame. Their solar-light needs are a separate question from physical fit: a door can have compatible holes but still be a poor solar location. French-door installations are listed as incompatible on the current Solar product pages.

A quick go/no-go workflow

  1. Confirm the lock type. You want a single-cylinder deadbolt, not a mortise lock, interconnected lockset, multi-point mechanism, or a door with a second active lock that changes the installation.
  2. Measure before removing anything. Record thickness, crossbore, backset, edge bore, faceplate shape, and clearance with the door open and closed.
  3. Match the exact model. Use the Lockin Smart Lock Selector, then open the exact product page and installation guide for the model you are considering.
  4. Stop at an unresolved mismatch. A 38 mm opening, rounded edge opening, mortise case, storm-door arrangement, French door, unusual trim, or insufficient frame clearance is a support question—not a cue to drill immediately.
  5. Check the door operation. Before installing the smart lock, the existing deadbolt should extend and retract smoothly without pushing or pulling the door. A smart lock cannot correct a binding door or a misaligned strike.
  6. Install and test with the door open first. Follow the exact quick-start guide. Test locking and unlocking while the door is open, then close the door and confirm the bolt enters the strike without resistance.

When new drilling may still be the wrong answer

Avoid modifying a fire-rated, shared, or institutional opening without qualified review. A new hole can affect the door, frame, weather sealing, egress, warranty, or a rental agreement. Lockin’s fit guidance is not a substitute for local code or building approval.

Also avoid using “standard deadbolt” to describe a door with a mortise body, narrow stile, multi-point hardware, French-door configuration, storm-door interference, or a non-rectangular latch opening. Those conditions can look close in a photo while failing during installation.

The practical answer

Will a Lockin smart lock fit a standard single-cylinder deadbolt without new drilling? Often, yes—if the existing preparation matches the exact Lockin model. Veno Go makes the most direct no-drilling claim for most standard US doors. Veno, Veno Plus, Veno Pro, Veno Solar Palm, and Veno Solar Face still require model-specific measurement and clearance checks.

If your measurements are clear, use the exact model’s quick-start and user-manual resources as the installation authority. If they are not clear—especially around a 38 mm crossbore, latch shape, mortise hardware, storm door, or frame clearance—pause and contact Lockin support with the model name, measurements, and photos. That short check is safer than drilling first and discovering that the door preparation cannot be restored cleanly.
