Introduction: Meet the EZVIZ DL01S Smart Deadbolt Adapter
EZVIZ DL01S Smart Deadbolt Adapter (CS-DL01S) – Inside Mount, Bluetooth & Zigbeeis a DIY, inside-mount smart deadbolt adapter designed to add keyless convenience to an existing deadbolt without replacing the exterior cylinder. The DL01S clips or mounts to the interior face of most standard deadbolts and brings local Bluetooth unlocking, app control, auto-lock scheduling and optional keypad support. For those who want remote access and cloud features, the DL01S pairs with the EZVIZ A3 Home Gateway (sold separately) to provide EZVIZ Connect via Zigbee.
- No-drill, inside-mount installation that preserves your existing exterior hardware and keys.
- Local Bluetooth unlocking through the EZVIZ app and optional keypad entry (in select SKUs).
- Configurable auto-lock, lock schedules and a privacy/do-not-disturb mode.
- Support for temporary and permanent PINs (requires keypad for PIN entry when not using the app).
- Door sensor integration for auto-lock and door status monitoring; some kits include a built-in doorbell.
- Remote control, push notifications and multi-device management when connected via the EZVIZ A3 Home Gateway (Zigbee).
Detailed specifications and benefits
The DL01S is designed to be compact and straightforward to install. Below are its primary specifications followed by what they mean in practice for homeowners and renters.
- Model:CS-DL01S (DL01S).
- Product type:Inside-mount smart deadbolt adapter.
- Materials:Plastic housing with an aluminium alloy knob.
- Dimensions (H×W×D):126.9 × 43.2 × 56.9 mm.
- Power & batteries:4 × AA alkaline batteries (typical packs include batteries).
- Connectivity:Local Bluetooth for app unlocking; remote access via EZVIZ Connect (Zigbee) when used with the A3 Home Gateway (sold separately).
- Operating conditions:−25°C to 55°C, 10%–95% non-condensing humidity.

- Compliance:CE / UKCA / RoHS / WEEE / REACH depending on region.
- Keep your current keys and exterior hardware:Because the DL01S mounts inside the door, you retain your existing cylinder and key access. That’s ideal for renters, landlords and anyone who prefers to keep the exterior look or who has a master key system.
- Simple power solution:Uses readily available AA alkaline batteries. Typical battery handling is straightforward and low-cost, with low-battery alerts to minimize lockout risk.
- Local-first design:Bluetooth control means you can operate the lock even without internet access. This reduces reliance on cloud services for day-to-day use while keeping the option of remote access through the A3 gateway.
- Flexible integration:With Zigbee support via the A3 gateway, the DL01S can become part of a broader smart home ecosystem for automations and notifications.
Use cases and scenarios where the DL01S excels
The DL01S is well suited to a range of practical scenarios where convenience, minimal installation impact and budget-conscious smart upgrades matter.
Renters often face restrictions when modifying doors or replacing locks. The DL01S installs on the interior face without drilling into the door surface or changing the external cylinder, making it an excellent, reversible option for tenants who want smart access without permanent alterations.
If your door has a decorative or custom exterior cylinder, or your home uses a keyed master system you can’t replace, the DL01S upgrades to smart functionality while leaving the exterior hardware intact.
Owners of short-term rentals can benefit from temporary PINs (when using an optional keypad) and Bluetooth-based guest access. When combined with the A3 gateway, hosts can manage remote access, monitor lock status and set schedules for cleaners and guests.
People who want a quick install without replacing the entire lock will appreciate the no-drill approach. Installers who prefer to keep the existing cylinder for compatibility or client preference can use the DL01S to add smart features quickly.
Comparisons with similar products
Retrofit smart lock adapters and replacement smart deadbolts fall into two categories: inside-mount adapters that preserve the exterior cylinder, and full smart deadbolt replacements that swap the whole lock. Here’s how the DL01S compares to common alternatives.
- Installation:Full replacements require removing the existing deadbolt and exterior cylinder; the DL01S installs inside and generally avoids exterior modification.
- Security model:Full replacements integrate the entire lock mechanism and may offer higher mechanical security certifications. DL01S preserves the existing cylinder’s mechanical security while adding electronic convenience.
- Feature set:Many full replacements include Wi‑Fi/bridge options and sometimes built-in keypad or touchscreen on the exterior. DL01S focuses on interior convenience with optional keypad bundles and remote features via an external gateway.
- Connectivity:August and Danalock offer Bluetooth-based control, often with optional Wi‑Fi bridges for remote access. The DL01S uses Bluetooth locally and Zigbee via the EZVIZ A3 gateway for remote/cloud features.
- Smart-home integration:If you already run a Zigbee-based smart home with EZVIZ or compatible systems, the DL01S plugs into that ecosystem with the A3 gateway. Other adapters may integrate with different ecosystems or have their own bridges.
- Price and bundles:Pricing varies by SKU. The suggested retail price for the DL01S is USD 179.99, which sits in the mainstream range for retrofit smart lock adapters. Bundle options with keypad and sensors make it flexible for different budgets.
Customer feedback and real-world impressions
Official customer reviews for the DL01S vary by retailer and region, but common themes from users of inside-mount retrofit locks include:
- Pros:Quick, non-invasive installation; maintaining existing exterior hardware; straightforward app-based unlocking and scheduling; good value when available in bundled SKUs.
- Cons:Remote/cloud features require the separate A3 gateway, which is an extra expense for users who want full remote control and notifications; battery life is tied to AA cells so performance varies with usage patterns; compatibility checks are important because not every deadbolt shape fits every adapter.
If you’re reading retailer reviews, look for comments on fit with your specific deadbolt model, battery longevity under heavy use, and whether the SKU you purchased included the keypad or door sensor if those are important to you.
Installation, safety and practical tips
- Check compatibility first:Review the official manual and compatibility list before purchase to ensure your deadbolt’s dimensions and clearance match the DL01S mounting plates.
- Install on the inside only:The DL01S is intended for interior mounting. Do not mount externally or attempt to modify the product housing.
- Keep a mechanical backup:Always ensure you retain mechanical key access to the door in case of battery depletion or unforeseen issues, and test function after installation.
- Plan for remote features:If you require remote unlocking and push notifications, budget for the EZVIZ A3 Home Gateway and plan placement for reliable Zigbee coverage.
Conclusion: Why the EZVIZ DL01S is a solid choice
The EZVIZ DL01S Smart Deadbolt Adapter is a practical, budget-conscious way to add smart features to an existing deadbolt without replacing exterior hardware. It’s especially appealing for renters, landlords and homeowners who want a reversible, no-drill solution. The combination of local Bluetooth operation and optional Zigbee-based remote access through the EZVIZ A3 gateway offers flexibility: use it as a standalone local smart lock or integrate it into a wider smart home setup.
Bottom line:If you want a non-invasive, easy-to-install smart lock adapter that preserves your current keys, provides app conveniences like auto-lock and schedules, and can extend to cloud features with a separate gateway, the DL01S is worth considering. Be mindful that remote features require the A3 gateway and check the SKU contents to ensure the keypad or door sensor are included if you need them. For many users, the DL01S hits the sweet spot between convenience, cost and minimal door modification.
