AutoLock AV4: The Game-Changer for Fabricators, Installers, and End Users

Resolving Industry Challenges Head-On

Thermal expansion remains a major challenge across the door industry, causing functional issues, increased service visits, driving up service costs, and frustration for both installers and end users.

With record high temperatures continuing, elevated and prolonged heatwaves are placing even greater stress on door systems, leading to misalignment and compromised performance. These conditions aren’t going away, and neither are the inefficiencies they create for fabricators and installers.

Recent Keystone market research into UK consumer fenestration trends revealed that 58.5% of respondents who identified security frustrations with their current doors, expressed a desire for better locks. It’s clear the market is calling for a change.

autoLock AV4 from Winkhaus answers that call. With its ultra-low force-to-operate and wide installation tolerances, AV4 is engineered to stay dependable in all conditions, across all door materials and usage environments, AV4 performs where others falter.

A Lock That Works, Even When Others Don’t

AV4 delivers the reliability and simplicity installers and fabricators need. Independent testing shows that AV4 requires up to 70% less force to operate than alternative systems. This makes it easier to use, reduces wear and tear, and extends product life, cutting down on service visits and complaints.

The system engages automatically with two anti-pushback hooks locking into place when the door closes, no lifting of handles or turning of keys. It’s PAS24 compliant and Secured by Design approval, combine peace of mind with day-to-day practicality.

Built for Efficiency in Fabrication and Installation

For fabricators, AV4’s non-handed design reduces stockholding by up to 50% and simplifies ordering. Shared routing with other Winkhaus multi-point locks allows for easy interchange of functionality through fabrication and installation.

For installers, the system helps avoid costly call-backs thanks to its ultra-dependable low-force operation, even when installed under pressure or exposed to shifting conditions over time.

Proven in the Field – Backed by End Users

In user testing, AV4 consistently outperformed competitor locks under simulated conditions that pushed doors beyond normal industry tolerance levels. Participants highlighted the ease of use, reliability, and long-term benefits.

Javaria, a landlord managing multiple properties, said: “Over time, doors become inherently more difficult to open. AV4 will reduce callouts and be easier to use for tenants in the future.”

Lee, a homeowner, commented: “Even as the door gets older and is open to the elements and wear and tear, it works—it was absolutely excellent.”

In 2025, it returns as a finalist in three categories: Door Component of the Year, Best Use of Video (for the AV4 end user film series), and again for Digital Marketing Campaign of the Year.
