Its 4-pin cylinder plus dual ball bearings contribute to strong pick resistance and smooth operation. The design emphasizes durability for outdoor fences, sheds, and gates, while providing weather protection for extended outdoor use. When selecting a padlock for gates, this model offers a proven balance of security and environmental resilience.
Gate Lock XLB – Secure Keyless Fence Lock

The XLB gate lock uses a 2-way keyless code system to open the lock, with a mechanism that activates the latch by pulling a wire through a post. It is designed for wood or vinyl gates and can swing in either direction. The lock box is a larger 3″ by 5″ unit with XL dials, offering easier readability and operation. Installation details and hardware are included, and the device is US and Canada patent protected. This model suits gates where a robust, weather-tolerant keyless entry is preferred over traditional keys.

The installation kit includes all necessary hardware, facilitating a straightforward setup. The latch is intended to enhance yard security by ensuring the gate locks automatically after closing, reducing the risk of accidental openings. It combines simple operation with durable construction suitable for outdoor gate applications.
Buying Guide: Key Purchase Considerations
- Security level: For outdoor gates, look for hardened materials (boron-carbide shackle, laminated steel bodies) and anti-tamper designs. Compare lock types: combination, keyless, smart, and mechanical pawl designs.
- Weather resistance: Opt for weatherproof coatings, rust-resistant hardware, and IP ratings for electronic locks to ensure operability in rain, humidity, and temperature shifts.
- Unlocking method: Decide between keypad, combination, RFID, Bluetooth/smartphone access, or traditional keys. Smart options add convenience but may require batteries or connectivity.
- Installation compatibility: Confirm gate material (wood, vinyl, metal) and backset or latch alignment to ensure a proper fit with mounting hardware and strike plates.
- Maintenance: Consider ease of rekeying or resetting combinations, as well as availability of replacement parts and spares for longevity.
- Size and fit: Check shackle height, lock body dimensions, and post dimensions to avoid overhang or clearance issues on fences and gates.
- Code management: For combination locks, ensure the ability to reset codes easily and securely. For shared access, consider a system with multiple user codes or admin controls for group use.
When choosing the right lock for a backyard gate, weigh the environment, gate material, and desired access method. A combination of mechanical durability and weather resistance typically yields the best long-term security with minimal maintenance for outdoor gate applications.
