A solar smart lock can reuse existing apartment deadbolt holes only when the exact model and selected accessories match the door preparation and the replacement is permitted. Before buying, compare the lock’s current installation guide or template against your door, and do not assume that “standard deadbolt” or “no drilling” means every model will fit every apartment door. For Lockin shoppers, this distinction matters. Lockin offers Veno Solar Palm and Veno Solar Face as solar-assisted smart lock options to evaluate, but a general no-drilling claim does not establish that these specific Veno Solar models install on every U.S. apartment deadbolt without drilling. Lockin also has Veno Go Palm Vein Smart Lock product information that supports no-drilling installation for that model, but that claim should not be automatically applied to Veno Solar Palm or Veno Solar Face.

Short Answer: Maybe, But Confirm the Door, Lock, and Lease First

A no-new-holes installation depends on three things: the existing deadbolt cutouts, the hardware design of the smart lock, and the rules for your rental unit. Some smart locks are designed to use existing door holes; others may require a different latch, strike plate, mounting position, or optional handle hardware.

What “Standard Deadbolt” Means Before You Buy

In practical homeowner terms, a “standard deadbolt” usually means your door already has common deadbolt preparation: an existing face bore, an edge bore for the bolt, a backset that places the latch correctly, and an aligned strike plate in the frame. But “standard” is not precise enough to buy on by itself. Before choosing a solar smart lock for an apartment deadbolt, check:

• Door thickness, then compare it with the product’s official installation requirements.
• Backset, meaning the distance from the door edge to the center of the lock bore.
• Existing bore holes and whether the new exterior and interior hardware will cover the old footprint.
• Whether your current lock is a single-cylinder deadbolt or a different configuration.
• Bolt and strike plate alignment, especially if the door already rubs, sticks, or needs lifting to lock.
• Whether the apartment door has unusual trim, a narrow stile, a security plate, or a handle set that could interfere.

If the official template does not clearly match your door, ask before buying. Record each accessible door measurement beside the corresponding requirement in the exact model's installation template. Mark mismatches and concealed dimensions separately. Send support the model name, existing lock details, door photos, and unresolved measurements before buying; do not substitute trim dimensions for hidden holes.

What “No Drilling” Can Mean for an Apartment Door

“No drilling” can mean several different things. It might mean the lock replaces the existing deadbolt using the current holes. It might mean a retrofit design attaches over part of the existing hardware. Or it might mean the main lock body does not need new holes, but an accessory, handle, or strike adjustment still might. A no-drill claim for one Lockin model should not be treated as a no-drill claim for every Lockin model or configuration. Check the complete selected package, including its accessories.

For renters, the safest question is not just “Is it no-drill?” Ask these more specific questions:

• Does the exterior unit use the existing deadbolt hole?
• Does the interior mounting plate require any extra screws beyond existing hardware points?
• Does the included or optional handle require new holes?
• Does the strike plate need to be replaced, moved, or enlarged?
• Can the original lock be reinstalled at move-out without visible changes?

Solar-Assisted Smart Locks Still Need a Battery Plan

Solar-assisted charging is not battery-free. A solar smart lock still needs a battery plan because night, winter, cloudy weather, shaded entrances, and indoor apartment hallways can reduce available charging light. Use the power-and-recovery questions below when evaluating a solar smart lock. Solar can help reduce routine charging in suitable conditions, but it should not be treated as permanent power. Observe the installed panel position rather than a nearby bright area, and keep a normal charging routine ready if the location does not qualify for meaningful solar assistance.

Veno Solar Palm and Veno Solar Face include ABX3™ Perovskite Solar Self-Charging and USB-C emergency power based on provided Lockin product facts. That means they are relevant options if you want a lock designed around solar-assisted charging, but it does not mean you can ignore charging, backup access, or low-battery warnings.

The current Solar product pages do not recommend apartment entries without daylight for solar charging. A bright-looking indoor hallway does not establish suitable daylight at the panel; resolve that placement condition independently of whether the lock fits the existing holes.

• How much direct or ambient light reaches your door on a typical day?
• Is your apartment door inside a hallway with little natural light?
• What does the lock do when the battery is critically low?
• Where is the emergency power port, and what cable or power source is needed?
• Are there mechanical key or other backup access methods you can use if electronics are unavailable?

Renter Rules: Permission, Original Hardware, and Move-Out

If you rent, check your lease and building rules before replacing a lock. Some landlords or property managers restrict lock changes, exterior appearance changes, rekeying, or any modification that affects their access in an emergency. A practical renter plan is to:

• Ask for written permission when your lease or building rules require it.
• Keep the original deadbolt, screws, strike plate, keys, and packaging.
• Avoid modifying the door or frame unless explicitly approved.
• Confirm whether the exterior side of the lock is allowed to look different from other units.
• Plan how you will restore the original hardware at move-out.

A no-new-holes installation can reduce the chance of permanent damage, but it does not automatically satisfy lease rules. Keep the written scope and original parts together, and agree on who will inspect the restored door before the move-out deadline.

How to Evaluate Lockin Veno Solar Options Safely

For this question, Veno Solar Palm and Veno Solar Face are the Lockin products most directly tied to solar-assisted smart lock evaluation. Veno Solar Palm is associated with palm vein unlocking, while Veno Solar Face is associated with 3D Face Recognition. Both are positioned around ABX3™ Perovskite Solar Self-Charging and smart access features.

Still, the purchase decision should separate confirmed product features from installation assumptions. If your top requirement is “solar smart lock apartment deadbolt no drilling,” review the current official installation guide for the exact model and configuration you want. If you are considering a broader Veno setup, note that products such as Veno Palm Vein Recognition Smart Lock, Veno Plus Palm Vein Recognition Video Smart Lock, and Veno Pro Palm Vein Recognition Video Smart Lock may have different installation and solar accessory considerations than Veno Solar Palm or Veno Solar Face.

Match the selected lock, any handle and any solar accessory to their own installation instructions using the checklist below. If a concealed measurement or required fastener cannot be confirmed, send support the model and the unresolved location before removing the existing hardware. Do not turn an unclear fit into an improvised modification on a rental door.

Pre-Purchase Checklist for a No-New-Holes Installation

• Measure door thickness and compare it with the current official manual.
• Check backset and existing bore hole placement.
• Confirm your current deadbolt type, especially whether it is single-cylinder.
• Inspect strike plate alignment and door-frame condition.
• Compare exterior and interior hardware footprints.
• Confirm whether the specific Lockin model requires new holes, a different latch, a different strike plate, or optional handle hardware.
• Check how much light reaches the door during normal days, including winter and cloudy conditions.
• Review backup power instructions, including USB-C emergency power where supported.
• For renters, confirm permission and keep all original hardware.
• If anything is uncertain, contact Lockin with photos and measurements before buying.
