Rulart Double Keyed Deadbolt Lock – Satin Stainless Steel
The Rulart two-sided deadbolt offers a robust security setup with keys that work from both sides. This model uses a solid copper cylinder keyhole and a solid steel latch, with anti-pry and anti-collision features intended to deter forced entry. The backset is adjustable to fit doors between 35 mm and 50 mm thick, and the latch plate can accommodate back plates of 60 mm or 70 mm. This makes it suitable for doors where privacy or controlled entry is a priority. It is best for homeowners who want durable, tamper-resistant hardware and do not require smart features or Wi-Fi connectivity.
Who it’s best for: Homeowners seeking a high-security, double-key system for exterior doors or interior doors where privacy is needed. It’s also a good fit for doors that require a flexible backset due to renovation or non-standard frame dimensions.
Why selected: The combination of a copper cylinder, steel latch, and anti-pry features provides a higher security profile than basic locks. The two-way key system allows entry from either side, which is useful in households with multiple constant access points.
Caution: The latch plate is not removable, which may affect installation options on some door configurations. Each lock uses a unique key, so portability of multiple locks without rekeying is limited.
Lock Scout Deadbolt with Round Trim – Keyed 2 Sides
This model emphasizes easy installation and adjustable backset options, making it well-suited for renters or DIY remodels. It supports backsets of 60 mm (2-3/8″) and 70 mm (2-3/4″), with a removable round corner faceplate and optional drive-in collar for a cleaner installation. It fits both right- and left-handed doors and handles door thicknesses from 35 mm to 45 mm, which covers many standard residential doors. This lock is best for those who value quick upgrades and flexible hardware compatibility over advanced electronic features.
Who it’s best for: Renters or first-time homeowners looking for a straightforward, reversible installation that can adapt to multiple door types.
Why selected: The universal design and adjustable latch provide broad compatibility, reducing the need for specialized backset measurements and multiple hardware options.
Caution: It may lack the higher-security features of premium models; consider supplemental security measures for highly exposed entry points.
Rulart Double Keyed Deadbolt – Satin Stainless Steel (Black, Double Side)
This is a double-sided deadbolt designed for strong privacy protection with dual-side key access. The same high-security features as the satin stainless version apply, including a copper cylinder and solid steel latch with anti-pry and anti-collision properties. The backset ranges from 35 mm to 50 mm, and back plates can be 60 mm or 70 mm. Its black satin finish offers a distinct aesthetic suitable for contemporary metal doors or doors that coordinate with matte black hardware.
Who it’s best for: Homeowners seeking a visually distinct, high-security double-sided deadbolt with a durable matte finish that pairs well with black hardware themes.
Why selected: It provides the same level of security as the silver version and offers a different visual style to match certain door designs.
Caution: Like other non-smart locks, it requires physical keys on both sides, which could be inconvenient during routine use or for households favoring keyless entry.
Richelock IU52 Double-Sided Keypad Door Lock
The Richelock IU52 is a dual-sided keypad door lock designed for both outdoor and indoor use. Each side features an identical backlit keypad for codes and a pair of mechanical keys. The system supports up to 50 unique codes per side and includes a code-synchronization feature so programs on one keypad mirror to the opposite side. It also offers a peep-proof security feature to deter code observation and supports a smart auto-lock function with adjustable timing. This model suits high-traffic entrances where keyless access improves convenience without compromising security.
Who it’s best for: Property owners who want convenient, hands-free entry for guests or family members while maintaining dual-sided control and robust security features. Great for gates, exterior doors, or entry points with frequent access needs.
Why selected: The dual-sided keypad with code synchronization and peep-proof design provides strong security and streamlined management for residences or semi-public spaces.
Caution: Electronic locks require power in some configurations and may need battery replacements or programming; ensure the installation site has reliable power access or battery egress as needed.
SCHLAGE B62N622 Deadbolt – Matte Black
The SCHLAGE B62N622 is a two-sided keyed deadbolt designed for exterior doors requiring strong security. It features a snap ‘n’ stay design intended to hold the bolt in place during installation and offers ANSI/BHMA Grade 1 security, providing high resistance to common forced-entry methods. This model is well-suited for traditional door setups that prioritize dependable mechanical security without smart features. It requires careful measurement of backset, cross bore, and door thickness to ensure a correct fit.
Who it’s best for: Homeowners seeking a proven, high-security deadbolt with a durable finish and a straightforward installation process for exterior doors.
Why selected: The Grade 1 rating and reinforced construction make it a reliable choice for doors where security is a primary concern. The double-sided operation increases protection against break-ins compared to single-sided options.
Caution: Accurate sizing is essential; incorrect backset or cross bore measurements can lead to improper fit or installation challenges.
Buying Guide: Key Considerations for Choosing a 2 Sided Door Lock
What door type and backset are supported?
Most two-sided deadbolts support backsets in the 35–50 mm range, with some models offering 60–70 mm options. Measure your door thickness, backset, and bore size before buying. Choose a model that fits your door’s existing prep work to avoid reworking the door.
Security level and materials
Look for hardened steel latches, copper or brass cylinders, and anti-pry or anti-bump features for enhanced security. Materials like satin nickel, oil-rubbed bronze, or matte black finishes provide both durability and style. ANSI/BHMA ratings indicate the level of security the lock offers; higher ratings equate to greater resistance to forced entry.
Keyed vs. keypad and access methods
Traditional keyed options offer reliable access with minimal maintenance. Keypad or smart features provide convenient keyless entry but may require power or battery maintenance. Dual-sided systems allow access from both sides, which is useful for entrances that require frequent handoffs or multi-point access control.
Installation considerations
2026-era two-sided locks vary in complexity. Some models are designed for quick upgrades with universal backsets and reversible latches, while others may require more precise alignment with existing bore holes. If you’re a DIY installer, seek models advertised as easy to install with clear mounting hardware and adjustable components.
Maintenance and durability
Regularly inspect latches and cylinders for wear. Choose locks designed for enduring daily use, with capabilities to withstand weather exposure if installed on exterior doors. If you live in harsh climates, consider weather-resistant finishes and powder-coated housings.
Rental vs. homeowner needs
Renters often benefit from easy installation and reversible hardware, while homeowners may prioritize higher security grades, anti-pry features, and longer-term durability. If you anticipate frequent guests or service visits, a keypad or code-sharing feature can be advantageous.
Summary tips for decision making
- For high security: prefer models with solid copper cylinders, anti-pry designs, and ANSI Grade 1 or higher ratings.
- For ease of installation: choose locks with adjustable backsets and removable trim plates where applicable.
- For convenience: consider dual-sided keypads or smart entry options with code synchronization when needed.
