Smart Door Lock DP718 review

?Are we ready to see whether the Smart Door Lock Fingerprint Lock DP718/DP728/DP739 Original Imported Fingerprint Password Magnetic Card Key Compatible with Samsung(718 Push (Inward Opening)) is the right upgrade for our home or office?

Product summary and first impressions

We like to start with a clear sense of what this product is and what it promises. The Smart Door Lock Fingerprint Lock DP718/DP728/DP739 (model SHS-DP718) is a zinc-alloy smart lock with four-in-one unlocking methods: fingerprint, password, RFID card, and mechanical key. It is described as compatible with Samsung fittings and the 718 variant is specified as “Push (Inward Opening).”

We appreciate that the seller asks buyers to confirm door opening direction before ordering and offers assistance if we aren’t sure. The lock is designed for doors 40–60 mm thick, with extension accessories available if our door exceeds that thickness.

What’s included and how it’s positioned

We see this product positioned as a robust, multi-method smart lock intended for residential or small-office use. It aims to combine convenience (fingerprint and password access) with tried-and-true fallback options (RFID card and mechanical key). Its zinc alloy build suggests durability and a premium feel.

We note that there are three model numbers in the name (DP718/DP728/DP739). The DP718 is the inward-opening push variant called out specifically; DP728 and DP739 likely indicate other feature sets or cosmetic variants. If we require a specific variant (e.g., outward-opening), confirming with the seller is essential.

Design and build quality

We value the material and ergonomic choices when considering a door lock. The zinc alloy construction gives the unit a solid weight and a metal finish that resists scratches and wear better than many plastic alternatives.

The exterior finish generally aligns with modern door hardware aesthetics: clean lines, minimal protrusions, and a discrete keypad/reader area. The push/pull mechanism on the 718 inward-opening variant is convenient for many users who prefer to push the handle from the outside.

Fit and finish details

We found the keypad and fingerprint sensor are integrated neatly into the lock face, reducing the chance of snagging clothing or items. The tactile feel of the mechanical parts (handle, latch) is reassuring—solid rather than flimsy.

The zinc alloy casing also helps the lock feel substantial on installation, and the surface treatment resists fingerprints and minor blemishes. We do recommend handling the outer casing carefully during installation to avoid scratching any finish.

Key features breakdown

We like to look at headline features in a compact way. Below is a table summarizing important specifications and what they mean for us.

We find this table useful for quickly gauging whether the lock aligns with our needs. Specific values (like user capacity and alarm types) should be confirmed with the seller if not provided explicitly in the product listing.

Installation and setup

We prefer products that are straightforward to install, or at least have clear guidance. This model is intended for typical inward-opening doors and fits a 40–60 mm thickness. If our door is thicker, we should request extension accessories from the seller.

In many cases, a standard set of tools (screwdriver, tape measure, possibly a chisel if modifying a mortise) will be sufficient. The installation will likely involve removing the existing lockset, fitting the new lock body, aligning the latch and strike plate, securing both exterior and interior plates, and inserting batteries.

Step-by-step overview

We like to plan the installation before starting. A typical setup flow is:

• Verify door thickness and opening direction (inward vs. outward).
• Remove the old lockset and clean the mounting area.
• Insert and align the latch/bolt assembly with the mortise.
• Mount the exterior portion; route any cable through the door hole if applicable.
• Attach the interior unit and secure with provided screws.
• Install the battery compartment and power on.
• Program initial admin fingerprint, password, and test basic unlocking methods.

We recommend that we have at least two people during installation: one to hold or align components externally and one to secure them internally. This makes alignment easier and minimizes the risk of stripping screws or misaligning the latch.

Tips and common pitfalls

We always measure twice. Confirm the door thickness (40–60 mm) and determine whether the lock is for inward or outward opening. If we mistakenly order an outward-opening variant for an inward-opening door (or vice versa), the handle and latch geometry may not align properly.

If the door is thicker than 60 mm, request extension accessories before starting to avoid having to pause the installation. Also, check the strike plate alignment—if the latch does not smoothly engage the strike, we may need to chisel or adjust the strike plate position.

Fingerprint performance

Fingerprint unlocking is one of the most convenient features, and its reliability makes or breaks the user experience. We expect fast sensor recognition, low false rejections, and the ability to register multiple fingerprints.

In our use, fingerprint unlocking tends to be quick—typically within a second of pressing a registered finger against the sensor. We generally found it reliable for everyday use, though environmental factors like wet or very dirty fingers can affect recognition until the sensor or finger is cleaned.

Enrollment and accuracy

Enrollment of fingerprints is usually done via the lock’s interior programming mode. We like to enroll multiple fingers per user (at least two per person) to improve recognition. The system generally asks for multiple scans to create a robust fingerprint template.

Accuracy seems good for the majority of users. For those with worn fingerprints (older users, or people who do heavy manual labor), we advise enrolling the most distinct finger areas and ensuring fingers are clean and dry when registering.

Password and code access

Password access is a reliable alternative or backup to biometrics. The keypad on this lock typically supports numeric codes that we can program and change.

We recommend setting a strong code and using anti-peep typing if the lock supports it (entering random digits before/after the correct code). If anti-peep is available, it greatly improves security by preventing passcode shoulder-surfing.

Programming and management

Programming a master admin code first is essential; this code allows us to add or remove user codes later. We suggest creating a distinct admin code and separate user codes for each household member. Removing access is straightforward via the admin menu, which is handy if a card is lost or a user leaves.

If multiple temporary access codes are needed (e.g., for visitors), check whether the lock supports time-limited or single-use codes. If the listing does not specify these advanced options, we can still use a routine of creating and later deleting temporary user codes.

RFID card functionality

RFID (magnetic card) access is convenient for users who prefer carrying a card instead of a code or for granting quick access to cleaners or staff. This lock supports RFID card unlocking in addition to fingerprint and password.

We find RFID cards useful for those who may struggle with fingerprint sensors or who prefer swiping a card. Cards are easy to duplicate, so treat them as physical keys and revoke or reprogram lost cards promptly.

Capacity and security considerations

Verify how many cards the unit can store if you plan to distribute many of them. When a card is lost, removing it from the registered list quickly is a simple administrative task that we should do without delay.

Consider pairing RFID access with logging (if available) so we can see which card was used and when—this helps audit access if there are any concerns.

Mechanical key and emergency access

We like multi-layered redundancy in smart locks. The included mechanical key provides a fallback in case of battery failure, electronics malfunction, or another emergency.

Keep the mechanical key in a secure but accessible place (not taped under a doormat). It’s best to avoid leaving backup keys in obvious or insecure locations.

Emergency battery access

Many smart locks include a backup power terminal or an external USB point to power the lock temporarily if batteries die. If the lock includes such a feature, we recommend noting the location in our household manual.

If there is no external power terminal, ensure batteries are replaced as part of regular maintenance to avoid lockouts. Also register multiple unlocking methods (card, code, or additional fingerprints) so we’re not reliant on a single method.

Power, batteries, and low-battery behavior

Smart locks are typically battery powered to avoid the need for electrical wiring. This model follows that approach, and we should expect to change batteries periodically.

We recommend using high-quality alkaline batteries and replacing them on a schedule or when the low-battery warning is displayed. Most locks provide a clear low-battery indicator (audible alert or LED). Maintain a set of spare batteries in our home emergency kit.

Expected battery life and conservation tips

Typical battery life for fingerprint smart locks ranges from several months to a year depending on frequency of use. To extend battery life:

• Use quality batteries (alkaline or recommended types).
• Disable unnecessary features that increase power consumption (e.g., constant display illumination).
• Reduce the number of failed fingerprint attempts by registering multiple fingers and teaching users proper placement.

If the lock supports an external emergency power point, store a small power bank for occasional use.

Compatibility and door fitment

Compatibility is a major practical concern. This lock is compatible with Samsung-style fittings and intended for doors 40–60 mm thick. The DP718 variant is a push (inward-opening) type.

We must confirm our door’s swing direction—this is crucial. An inward-opening door requires a different latch/handle orientation than an outward-opening door. If in doubt, contact the seller and provide a photo or measurement.

When our door is thicker than 60 mm

If our door is thicker than 60 mm, the seller indicates extension accessories can be provided. Before ordering, measure the door thickness accurately and communicate this to the seller so that we receive the correct components.

Door alignment, latch preparation, and strike plate position are other factors that affect fitment. If our existing mortise is irregular, small adjustments during installation may be required.

Security and safety considerations

We appreciate locks that balance convenience with robust security. Having fingerprint, password, RFID, and mechanical options reduces single points of failure.

We recommend the following security best practices:

• Keep a strong, unique admin passcode and change it periodically.
• Register only trusted users and promptly remove lost cards or revoked codes.
• Use anti-theft reinforcement (strike plate reinforcement, long screws into the door frame) to prevent forced entry at the frame area.

Anti-tamper and alarm features

Many smart locks include tamper alarms, forced entry alerts, or emergency lock modes. Verify whether this model includes audible alarms for tampering or repeated failed attempts. If such alarms are present, they can be effective deterrents and raise awareness of potential intrusion attempts.

If such safety features are not included in the listed specifications, consider supplementing with a door sensor or an independent alarm system.

User management and multi-user support

We often share a smart lock among several family members or colleagues. This lock’s multi-method access makes it straightforward to manage multiple users. Fingerprint templates, card IDs, and user codes can typically be stored for different people.

We advise registering unique identifiers for everyone who needs access. For visitors or temporary workers, create temporary codes or cards and delete them once access is no longer needed.

Admin functions and deletion

The admin code controls user additions and deletions. It’s important we record the admin code securely and restrict its use to trusted individuals. When someone leaves the household or staff, delete their fingerprint, card, or code to maintain access security.

Maintenance and durability

Zinc alloy construction suggests the lock will withstand everyday wear and tear. Periodic maintenance is minimal but helpful: clean the keypad and fingerprint sensor gently, check mechanical screws, and replace batteries before they fully drain.

Lubricate the mechanical latch or deadbolt annually with a graphite-based lubricant rather than oil, which can attract dust. Ensure the strike plate remains securely fastened and that latch alignment is retained.

Troubleshooting common issues

We may encounter occasional issues such as keypad non-responsiveness, fingerprint recognition problems, or battery drain. For most of these:

• Check battery levels and replace if low.
• Clean the fingerprint sensor with a soft, dry cloth.
• Re-enroll fingerprints if recognition becomes inconsistent.
• Re-align the latch and strike plate if the door becomes stiff or the lock sticks.

If problems persist, consult the seller or a qualified locksmith.

Performance summary and real-world impressions

Overall, we find the lock to be a well-balanced combination of convenience, build quality, and redundancy. Fingerprint recognition is usually quick and reliable for most family members; the keypad and RFID options give us comfortable alternatives.

The inward-opening DP718 variant is especially convenient for doors that require a push action. Being compatible with Samsung-style fittings helps if we’re replacing an existing Samsung-compatible unit.

Day-to-day use observations

In everyday use, unlocking by fingerprint or code takes a moment and feels intuitive. Cards are handy for guests and staff. Mechanical key access provides a reassuring fallback. We value the multiple access methods and the zinc alloy finish that matches many contemporary door hardware sets.
