Tigris®Premier4™ – Cutting Through the Nonsense of Key Security

A 3d render of gold Tigris Premier 4 key. on a simple neutral background. Engraved within the metal of the key reads 'TIGRIS Premier 4 Patent Protected'.
Let’s be honest — the key security world is full of noise. Marketing jargon. Smoke and mirrors. Talk of “restricted systems” and “trade marked keys” dressed up to sound like cutting-edge security. But here’s the truth: unless it’s patented, it’s not protected. Full stop. At Access2, we’ve been banging this drum for years — not just because it sounds good, but because it’s the only way to guarantee real control, real compliance, and real peace of mind.

Why Tigris®Premier4™?

Premier 4 is our latest and most advanced high-security mechanical key system. It’s the natural evolution of Premier 3, which has been trusted across commercial, retail, healthcare, and public sector applications for years. The key difference? The patent on Premier 3 expires in 2032. The patent on Premier 4 runs until 2042 — giving customers an additional decade of exclusive protection and legal security. In short: Premier 4 exists because our customers deserve a better, longer-lasting return on their security investment.

What Makes Premier 4 Different?

Premier 4 isn’t just a new name. It’s a total upgrade in design and performance:
  • Unique Branch Groove Keyway A patented design feature that makes illegal key copying practically impossible.
  • Dual Patent Protection It’s not just about the key — the barrel (cylinder) the key goes into is also patented. That’s two layers of defence, not one.
  • Side Elements for Complex Keying Systems Allows us to design highly bespoke master key systems without compromising on security.
  • Easy Key Entry Ergonomic upgrades make it easier for users to insert the key, improving usability without sacrificing control.
  • Backed by Patent Law — Not Marketing Spin We’re not talking about a logo on a key. We’re talking about registered intellectual property, enforceable in court.

Don’t Be Misled

Some systems are marketed as “patented” when the patent applies to an internal component or aesthetic design — not the key security itself. That’s misleading. With Access2, you’re protected where it matters most: the key AND the lock.

A System Built on Integrity

At Access2, 90% of what we supply are patented key systems. We’ve built our reputation on doing things properly — not just ticking boxes. Premier 4 is the result of that mindset: real innovation, real security, and real-world usability.

We don’t do gimmicks. We do proven solutions that protect our customers’ buildings, reputations, and bottom line.

Final Word

When your building’s security depends on keeping keys out of the wrong hands, there’s no room for half-measures. Tigris®Premier4™ offers one of the longest-lasting patents on the market, complete with mechanical innovations that make life easier for users — and harder for anyone with bad intentions.

Want a system that delivers long-term ROI and real peace of mind?

Let’s talk. Your security deserves more than a sales pitch.

Tigris®Premier4™ – Secure. Smart. Future-ready.

Access2 Announces New Southern Sales Manager: Poppy Rule Steps In

Access2, one of the UK’s leading suppliers of advanced locking and security solutions, is proud to announce the appointment of Poppy Rule as Sales Manager for the South of England.

Poppy has grown up around locks and keys – spending many a summer job in the production team – and now brings that lifetime of exposure into a dynamic sales role that blends legacy knowledge with a modern approach. “We’re thrilled to officially welcome Poppy to the sales team,” said Clint Robertson, Sales Director of Access2. “She’s shown incredible initiative, connected brilliantly with our customers, and is already shaping our southern presence. I’ve seen Poppy grow up around the company so this is a proud moment for us all.” Poppy will be supporting customers across the southern territory, continuing to champion Access2’s trusted product lines including Tigris Premier4, mechatronic cylinders, digital access systems, and bespoke security solutions. “I’ve loved getting to know our customers over the past year,” said Poppy. “Access2 has always felt like home, and now I’m excited to grow our footprint across the South – bringing great service, solid relationships, and a few laughs along the way.” For media enquiries or to connect with Poppy directly, please contact:📧 sales@access2.com
