Premier 4 Tigris® – 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 Premier 4 Tigris®?

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. Premier 4 Tigris® 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.

Premier 4 Tigris® – Secure. Smart. Future-ready.

Cylinder Options and Features

All cylinders perform the same basic task, but the details of their design and construction provide a range of additional features and benefits. A number of additional features are available as options within the Tigris® ranges of cylinder. Clutch Function When inserted the key disengages the thumb turn operation, and has priority over locking and unlocking. Often required in facilities for vulnerable people, it prevents a door being held locked by gripping the thumb turn on the inside. Classroom Function A variant of the clutch function. The key operation remains the same, however the thumbturn can only be used to unlock the door. Construction Cylinder Allows contractors to install and use the cylinder during the construction phase using a Construction Key. Once a valid system key is used, the internal pinning arrangement alters to negate and prevent any future use of the Construction Keys. Thumbturns We offer a range of thumbturns to suit different hardware ranges, aesthetics or for Special Needs requirements. Finishes An unrivalled number of finishes are offered through our Colourmatch service. As well as 10 standard finishes we are able to colour match any hardware finish you wish to specify.
