Locks & Keys — Advanced Security for Total Peace of Mind

Welcome to the home security and access control collection at THS Now. Your doors do more than separate rooms—they serve as the primary defensive barrier protecting your family, your property, and your peace of mind. A lock is only as reliable as its internal engineering; low-grade alloys or generic pin configurations can make an entryway vulnerable to bypass methods. At THS Now, we understand that compromise is never an option when it comes to security. We offer a strictly vetted selection of high-security padlocks, tamper-proof mortise assemblies, rugged rim locks, and cutting-edge biometric hardware designed to bring absolute protection to your space.

Choosing the Best Lock for Your Security Needs

Selecting physical security hardware requires matching the mechanical complexity of a locking unit to the specific asset risk level of your property. Relying on basic locks for high-value access points leaves your building vulnerable. Focus on these three core security principles when upgrading your entryways:

Interior vs. exterior door security

The placement of a door dictates its mechanical requirements. Interior doors (like bedrooms, bathrooms, and interior home offices) prioritize privacy and smooth daily operation over extreme force resistance. Lightweight cylindrical locks or low-lever privacy keys are perfectly adequate here. Conversely, exterior doors (main entrance gates, balcony access, back doors, and warehouse entryways) demand heavy-duty, pick-resistant hardware. These exterior points require deadbolts or multi-point locking systems constructed from solid brass or hardened steel to withstand forced entry attempts and brutal weather elements.

Understanding lever and cylinder mechanisms

The internal mechanism of a traditional manual lock heavily influences its tamper resistance. Classic lever locks utilize a series of flat internal plates (levers) that a matching bit-key must lift to precise heights to throw the bolt. Higher lever counts (such as 6-lever or 8-lever designs) make picking incredibly difficult. Modern high-security setups typically deploy pin-cylinder mechanisms, which utilize precise spring-loaded split pins. For maximum safety, premium cylinders feature computer-coded dimple keys and built-in anti-drill hardened steel pins that completely jam the cylinder if a drill bit tries to destroy the core.

The transition to smart digital locks

Physical keys are rapidly giving way to digital credentials. Upgrading to a smart digital lock eliminates the risk of lost, stolen, or duplicated physical keys. Modern smart locking units combine motorized physical deadbolts with multiple secure authentication methods, including advanced capacitive fingerprint scanning, encrypted RFID key fobs, custom numeric PIN codes, and smartphone app access via secure Bluetooth or WiFi networks. These digital systems also log precise entry times, allowing property managers to monitor access remotely.

Types of Locking Systems

To help you discover the exact mechanical configuration your project requires, the THS Now security catalog is organized into highly specialized hardware categories.

Heavy-Duty Padlocks

The ultimate classic solution for standalone security. Our heavy-duty padlock inventory features double-locking hardened steel or boron-alloy shackles that offer massive resistance against bolt cutters and hacksaws. Equipped with solid brass bodies and anti-pick cylinder tracks, these padlocks are ideal for securing rolling shutters, main boundary gates, utility sheds, and heavy industrial lockers.

Mortise & Handle Locks

Seamlessly integrate high-level protection with modern architectural aesthetics. Our mortise locksets fit completely inside a pre-routed pocket within the core of your wooden or metal door, making the mechanical deadbolt completely inaccessible to external prying tools. Paired with ergonomic, high-tensile designer pull handles and luxury escutcheon plates, these units provide the benchmark safety standard for main residential entry doors.

Night Latches & Rim Locks

Add an immediate, robust layer of secondary security to your existing entryways. Rim locks and night latches mount directly onto the interior surface of your door frame. Featuring automatic deadlocking spring latches and internal thumb-turns, these locks provide reliable protection for residential apartments and commercial back doors, ensuring the door locks securely the moment it clicks shut.

Multi-Key & Master Key Systems

Streamline access management across large commercial complexes, multi-family housing units, or expansive office buildings. THS Now provides specialized multi-key and master key configurations. This engineering layout allows individual users to open their specific designated doors with a unique personal key, while authorized personnel carry a single master key capable of unlocking every door across the entire facility.

Frequently Asked Questions

How do I choose the right size for a mortise lock?

To select the correct size for a replacement mortise lock, you need to measure two primary dimensions: the backset and the center distance. The backset is the distance from the leading edge of the door to the exact center of the keyhole or cylinder hole. The center distance is the measurement from the center of the handle spindle hole down to the center of the keyhole. Standard backset sizes for Indian doors typically range from 45mm to 60mm. Always verify these precise dimensions against the technical diagrams provided on THS Now before checking out.

Are your padlocks rust-resistant for outdoor use?

Yes. The THS Now collection includes specialized outdoor padlocks designed to withstand heavy environmental exposure. For external main gates, marine environments, or rainy areas, look for padlocks specifically designated as "weatherproof" or "marine-grade." These units feature solid brass or stainless steel bodies, internal drainage channels, and silicone shackle seals that protect the internal tumbler pins from water corrosion and grit accumulation.

Do you offer duplicate key services or sets with multiple keys?

We do not provide custom locksmith key-cutting services online; however, all mechanical locks in the THS Now catalog come standard from the factory with 3 to 5 original keys included inside the sealed box. For high-security installations where family members or staff require extra access, we recommend purchasing our dedicated cylinder lock ranges that include ultra-secure master key packages or upgrading to our smart digital locks, which allow you to issue unlimited digital access keys instantly.
