How We Work with Your Brand

When you start a new lock system project, you don’t want surprises – you want a clear path. Here’s how we usually move from first idea to final solution with your team.

1. Project Brief

You share your security needs, target market, installation requirements, and any ideas you already have for the locking systems. We ask practical questions about usage, certifications, and regulatory requirements to fully understand your goals.

2. Concept & Customization

Our team works with you to select the right lock models, materials, and smart technologies that meet your needs. We present tailored recommendations and customization options to match your brand, security level, and installation criteria.

3. Prototyping & Testing

We provide samples of the locks, whether physical mockups or standard prototypes, for your team to review. If needed, we support functional tests, including compatibility checks and security performance trials, before you finalize your choice.

4. Delivery & Installation Support

Once you’ve selected your locks, we assist with logistics and delivery. We also offer installation guidance and ongoing support to ensure a smooth setup, with the assurance that all systems are fully functional and meet your security requirements.
