Today, garage doors are a simple and effective entry point for burglars. While front doors have long sported obvious deadbolts and sophisticated smart cameras, garage doors are typically protected by old locks, which in seconds can be opened with a couple of minutes of tinkering and either a screwdriver, pry bar or even coat hanger. Because of this vulnerability, numerous anti-theft devices for the garage door lock kit have been invented and implemented, to protect both against brute force attacks, electronic manipulation and skilled picking. The article discusses what progress has been made with anti-theft systems - and what implications that holds for homeowners and owners of industrial facilities.
Rising Incidents of Lock Manipulation and Bypass Attacks
The Burglary Statistics will always illustrate that a number of residential & Business Property break-ins are forced through the garage doors. Existing pin tumbler locks & simple latch mechanism can be picked, raked, or snapped through easily. As there is a necessity, lock companies have developed anti-pick & anti-bump technologies for the garage door locks. Modern garage door lock sets consist of cylinder locks that contain spool pin, drivers that are serrated and a paracentric keyways resistant against the traditional picking devices. Such cylinder designs are used on their industrial locks like cylinder locks and lever handles (with IP65 rating) made by WenZhou MeiGu Lock Industry Co. Ltd. For example, the six pin, anti-bump cylinder can only exist on the lever handle. The mechanism involves minute details, of which most burglars lack the knowledge. In addition, strengthened steel or Zinc/Aluminium Die Casted housing secures the cylinder making it resistant against the plier method of snapping the cylinder in half. Such advanced features address the needs in the current scenario where basic locks have become obsolete.
Reinforced Mechanical Structures Against Prying and Spreading
Pick is not the commonest problem during a garage door raid, it's brutish brute force attacks. Attackers will pry their crowbars between the door and frame of a garage door e.g. Widening the space between door and frame to enable it to pop out. This method is common with single-point locking, which most modern garage doors will use. Unfortunately, security is developing: anti-theft is currently achieved using multi-point locking systems; enhanced strike plates etc.
One modern lock kit includes internal handle/rod locks, which lock the garage door to the frame on all 4 sides of the handle, and also top & bottom of the handle. Opening the handle causes strong steel rods to be fired into reinforced, hardened brackets on the frame; moving the centre of the door slightly outwards but retaining the connection between top/bottom rods and frame. MeiGu's hook/accessory range works very similarly to their industrial cabinets lock kit range, providing the same strength and rigidity, as well as incorporating strong hasps and anti-spread brackets, which prevents forced movement of the door. The mechanism's strengthening creates too much resistance for burglars attempting to get a grip of the door, so the attempt is likely abandoned and the door deemed too difficult to break into, forcing them elsewhere.
Drill-Resistant and Tamper-Proof Component Design
Another commonly used attack method is to drill through the lock cylinder and either shatter or break the pins, or drill through the cam mechanism. However, normal brass or zinc cylinders do not pose too much trouble to drill with a carbide drill bit, and now with anti-theft lock kits and material, it becomes drill resistant due to ball bearings within the cylinder faces and sacrificial anti-drill plate.
MeiGu's cylinder locks and cam locks utilize a series of hard steel pins and ball bearings in the face of the cylinder, that will either spin, or destroy the drill bit without being penetrated. In addition, cylinder blocks made from 304 stainless steel, 316 stainless steel forging or stamping, have proven exceptionally resistant to being drilled. Some of MeiGu's cylinders also have fake notches and trap pins so the lock will not operate once tampered with. These drill resistant locks are necessary for all types of applications, such as toolboxes for work vehicles, RV caravans where tools are stored.
Integration with Electronic Tamper Alerts and Smart Monitoring
Modern security builds on top of the mechanical anti-theft device; what modern security is concerned with is sensing the situation. New garage door lock kits may be retrofitted with electronics that detect events of attempted lock manipulation, such as heavy vibration, forceful rotation, or attempts to shear the lock body. A sensor that detects this sort of attempt will either trigger a local alarm, signal an alert to a smartphone, or activate a commercial security center. MeiGu's Cam lock cylindrical series type may have sensor cavities for micro switch or reed switch. An event like this causes the contacts to connect to either a hub device, or a commercial security panel. This provides a time critical notification to a security team that an attempt has been made to unlock the door, and allows the team to investigate potential theft of a high dollar item of equipment or high dollar merchandise which is stored in another area of a high dollar facility. More advanced options may even contain a "locking position monitor", ensuring that the deadbolt or locking rods are in fact fully extended, not merely an attempt has been made to extend them. This combination of brute force mechanical anti-theft devices and electronic awareness is a significant enhancement over "old lock kits".
Conclusion
Today's garage door anti-theft features are smartening up much faster than today's thieves as the method by which antis SOC perform are changing. Anti-pick cylinders and multi-point swing handle and rod systems, and drill-resistant parts made of stainless steel along with electronic tamper warn indicators make for important lines of defense.
