Protect Your Home With an Anti-Snap Lock Replacing the lock cylinder is an effective and easy way of making your home secure without having to change the entire lock or door. If you have an external PVCu or composite door, you can upgrade the euro profile cylinder to Yale’s new AS Platinum Series lock, then you can be assured that your home has the very latest security protection. The new AS Platinum Series euro profile lock cylinder offers four separate lines of defence to deter even the most determined attack. These include a snap-off front section, which will come away if attacked to give the intruder less of the cylinder to grasp; hardened grip defenders, which make gripping the rest of the cylinder difficult; a hardened reinforced bar – designed not to snap, but to flex in a way that will defeat the vast majority of intruders; and an interlocking cam with strengthening bar providing additional protection on the top section of the cylinder. In addition to these new lines of defence, the Yale AS Platinum still has the same great features that you would expect from the original Yale Kitemarked cylinder, including anti-drill, anti-screw, anti-bump and anti-pick protection. Whereas previously Yale AS Series cylinders were approved by Sold Secure SS312 Diamond Standard, we have moved away from this standard and focused all our development activities on the latest British Kitemark standard TS007. Homeowners throughout the UK recognize the Kitemark logo as a symbol of product quality and performance. Yale KM, AS and AS Platinum Series cylinders are all approved to TS007. Yales KM Series, AS Series and AS Platinum Series cylinders are also Secure by Design approved giving them the stamp of approval by the official police security initiative, the logo of which is clearly displayed on our packaging.
