Introduction: DL01S Smart Retrofit Deadbolt Kit and DL01CP Keypad — Key features at a glance
The DL01S Smart Retrofit Deadbolt Kit, bundled with the DL01CP external keypad, is a battery‑powered retrofit solution designed to modernise an existing deadbolt without replacing the entire lock. It provides keyless entry through the EZVIZ app and local access via an IP56‑rated outdoor keypad that supports passcodes and proximity cards. Designed for quick DIY installation, the package includes a door sensor, auto‑relock functionality, multi‑user code management and the convenience of battery power for homes where wiring is not an option.
Detailed specifications and benefits
The DL01S/DL01CP kit is engineered to balance convenience, weather resistance, and compatibility. Below is an organised look at what the kit contains, its technical specs, and the practical benefits they deliver.
- Model:DL01S (lock) + DL01CP (keypad)
- Product type:Retrofit smart deadbolt kit
- Key features:Keyless entry, auto‑relock, multi‑user codes, door sensor
- Lock dimensions:126.9 × 43.2 × 56.9 mm — compact profile that mounts over most standard deadbolts.
- Materials:Plastic housing with an aluminium‑alloy knob for a balance of weight savings and durability.
- Power:Lock runs on 4×AA alkaline batteries; keypad uses 2×AA alkaline batteries. This preserves convenience for homes without door wiring; batteries are widely available and simple to replace.
- Communication:EZVIZ Connect (Zigbee) — low‑power, local mesh networking ideal for home automation ecosystems.
- Remote features:Remote/online control and cloud notifications require the EZVIZ A3 Home Gateway (sold separately). Local keypad and in‑home app control work without the gateway.
- Keypad rating:IP56 — weather‑rated for outdoor installations and able to withstand rain and dust in typical residential conditions.
- Code capacity:Up to 50 code sets (6–10 digits) — supports families, guests, contractors and temporary access codes.
- Operating ambient:−25°C to 55°C, 10%–95% RH (non‑condensing) — suitable for many climates.
- Keypad features:Anti‑voyeur dummy digits to hide passcode length, proximity‑card support, built‑in doorbell and anti‑tamper alarm behaviour with LED indicators.
- Typical kit includes: DL01S lock actuator, mounting plates, batteries (pack), hex wrench, screwdriver, screw kit, door sensor and a quick start guide.
- Drill‑free retrofit installation:The lock mounts over most existing deadbolts, making it an attractive option for renters or homeowners who want a non‑invasive upgrade without replacing the entire lock hardware.
Benefits in everyday use
Beyond the raw specifications, the DL01S/DL01CP delivers tangible benefits for typical residential scenarios:
- Fast DIY installation:Drill‑free mounting minimises damage to doors and doorframes and shortens installation time compared with full deadbolt replacement.
- Flexible access control:Manage up to 50 code sets for family members, contractors and short‑term guests. Temporary or scheduled access reduces the need for physical keys and rekeying.
- Weatherproof outdoor keypad:IP56 rating and anti‑tamper features make the keypad reliable for external mounting while deterring casual tampering.
- Local and app control:Use the EZVIZ app for in‑home control and the keypad for local access. Add the A3 Home Gateway if you want remote control, cloud notifications and integration with a broader EZVIZ smart home setup.
- Added safety signals:The included door sensor provides door‑status notifications and works with auto‑relock to reduce accidental unlocked states.
Use cases and scenarios where the DL01S excels
The DL01S/DL01CP kit shines in several common real‑world situations where flexibility, ease of installation and multiple access methods matter:
Hosts can issue temporary codes to guests and change them between stays without replacing locks. Drill‑free installation preserves the property’s original hardware, helping comply with landlord requirements and simplifying end‑of‑tenancy reversals.
The ability to create distinct codes for family members and track usage (when paired with a gateway and cloud features) helps manage access for children, relatives and service providers. Auto‑relock ensures doors aren’t accidentally left unlocked.
Contractors and cleaners can be given time‑limited codes or proximity cards, removing the need to hand out physical keys. The doorbell on the keypad adds a familiar interaction point for visitors.
Because the DL01S mounts over an existing deadbolt, renters can add smart lock functionality without violating lease clauses about altering door hardware. Homeowners who prefer non‑invasive upgrades will also appreciate the straightforward install process.
How it compares with similar products
In the smart lock market there are several approaches: retrofit actuators that mount over existing deadbolts, full‑replacement smart deadbolts, and smart locks with integrated Wi‑Fi or proprietary bridges. Here’s how the DL01S/DL01CP stacks up in key areas:
Retrofit models (like the DL01S) install over your existing deadbolt and preserve the indoor thumbturn and exterior hardware. This is less invasive than full replacements (from brands such as Yale or Schlage) which require removing the existing lock hardware. Retrofit is faster and reversible, but full replacements may offer a sleeker integrated look and additional features like built‑in Wi‑Fi or advanced grading certifications.
The DL01S uses EZVIZ Connect (Zigbee) and needs the A3 Home Gateway for cloud features. Zigbee is low‑power and works well in mesh networks with other Zigbee devices. Some competing locks provide built‑in Wi‑Fi (no hub required) or include a proprietary bridge for remote access. If you already run a Zigbee‑centric smart home, the DL01S integrates naturally; if you prefer no hub, look for Wi‑Fi enabled alternatives.
Not all retrofit actuators include an IP56‑rated external keypad. The DL01CP adds outdoor usability with passcodes and proximity cards plus a doorbell — functionality some competitors only provide with additional accessories or higher‑cost full‑replacement models.
With a suggested retail price of around $199 the DL01S kit sits competitively against other retrofit solutions and entry‑level full‑replacement smart deadbolts. Pricing can be attractive for buyers seeking keypad access, weather resistance and a drill‑free install without paying a premium for integrated Wi‑Fi.
Customer feedback and typical reviews
While individual experiences vary, aggregated customer impressions tend to highlight the following themes:
- What users like:Many users praise the simple retrofit installation and the convenience of multiple access modes (app + keypad). The IP56 keypad gets good marks from owners who mount it outdoors, and the inclusion of a door sensor and auto‑relock are frequently appreciated for added security and peace of mind.
- Common concerns:Some customers note that remote access and cloud features require the EZVIZ A3 Home Gateway (sold separately), which is an additional purchase if remote control is desired. A few reviewers mention wanting more detailed battery‑life estimates or advanced integration notes for specific smart home platforms.
- Performance impressions:When installed correctly, reports indicate reliable day‑to‑day operation with smooth motor actuation and responsive keypad entry. Users in colder climates appreciate the specified operating range, and the anti‑tamper behaviours are reported as effective at discouraging casual interference.
Conclusion: Why the DL01S Smart Retrofit Deadbolt Kit is a strong choice
The DL01S paired with the DL01CP keypad is a practical, cost‑effective route to adding smart lock functionality to an existing deadbolt. It offers several standout advantages: drill‑free retrofit installation for fast DIY upgrades, robust weather‑rated keypad hardware for outdoor use, flexible multi‑user code management, and low‑power Zigbee connectivity that integrates into smart home systems via the EZVIZ A3 Gateway.
For homeowners, renters and property managers who want keypad access, temporary codes and the convenience of app control without a full lock replacement, this kit is an attractive option. Before purchasing, confirm that you are comfortable adding a Zigbee gateway if remote access is required, and check fitment using the manufacturer’s templates and instructions. With thoughtful installation and the right integrations, the DL01S/DL01CP kit modernises entry security while keeping the installation simple and reversible — a strong balance of convenience, weather resilience and cost.
