Lockwood 303 Single Cylinder Deadlock – High-Security Meets Easy Egress
At Aus Lock and Safe Co, we recommend the Lockwood 303 Deadlock for those who prioritize a quick exit without compromising on heavy-duty perimeter security. As a single-cylinder rim deadlock, it offers the perfect balance for family homes: high-strength protection from the outside and a simple turn-knob on the inside for a fast, keyless escape in an emergency.
Unlike standard nightlatches, the 303 features an interlocking strike and case, meaning the lock and the frame become a single, solid unit when engaged. It’s a "jemmy-resistant" powerhouse that has been a staple of Australian home security for decades.
Why the Lockwood 303 is a Professional Favorite
The beauty of the 303 lies in its robust engineering. It’s built with a thick-walled zinc alloy casing and a massive stainless steel bolt, designed specifically to withstand hammer and jemmy attacks. Because it is a Single Cylinder lock, it is particularly well-suited for solid doors where you want the convenience of never having to search for a key to get out of your house.

Details
- Locking Mechanism: Key
Features & Benefits
- Positive Deadlocking Action: Once the door is locked from the outside by key or from the inside by the turn-knob, the bolt is deadlocked—preventing "shimming" or "loiding" of the latch.
- Emergency Egress: The internal turn-knob is always free for exit, making it fully compliant with fire safety recommendations for a quick and easy departure.
- Jemmy Resistant: The interlocking case and mounting plate are designed to resist forced entry attempts using crowbars or hammers.
- Hinged & Sliding Door Compatibility: Unique among many rim locks, the 303 is suitable for both standard hinged doors and some sliding timber doors.
- Kinetic Defence®: Equipped with Lockwood’s pick and bump resistance technology to thwart sophisticated entry methods.
- Sleek Satin Chrome Pearl Finish: A high-quality, modern finish that provides excellent corrosion resistance and matches most contemporary hardware.
