How secure do you think a Push Button Lock really is? Push Button Locks are a simple way to control who can enter into rooms or buildings. You find them in all kinds of places. Jewellers, Hospitals, Schools, Airports, even Police stations. But think twice before you mistake them for being secure.

CodeGUARD 5 Under Test

CodeGUARD 5 from UNION is a new generation of push button mechanical locks, purpose-designed to bring serious security to access control.

CodeGUARD 5 has  been tested to the very limits of endurance. 200,000 punishing test cycles to make sure the BS3621 standard latch works first time, every time. Prolonged exposure to the destructive effects of corrosive salt water, making sure the 304 grade Stainless Steel construction keeps your door secure in the harshest conditions. And subjected to continual, brutal assault to ensure you can install a push button lock solution that delivers what you really want – reliable security that exceeds BS8607 Grade 5.

The result? A push button lock which you can install almost anywhere and will protect you from violent attack. This is access control that shrugs off abuse thanks to its fortress construction and integrated deadlocking latch that makes it much stronger than lesser alternatives.

CodeGUARD 5 reaches new performance levels never seen before. That’s why BSI awarded CodeGUARD 5 the new BS8607 Grade 5, the highest grade possible. Only devices that make this grade can use the coveted BSI Kite Mark. And with a 3 year guarantee as standard, you can safely recommend CodeGUARD 5 with the confidence to Fit and Forget.
