10 Different Types of Door Locks in India: Which One is Right for Your Home?

10 Different Types of Door Locks in India

Most people don't think about their door lock until something goes wrong—a break-in attempt, a jammed knob, or a landlord asking you to "just install something secure" before you move in. At that point, the sheer number of options on Amazon or at your local hardware store can be overwhelming.

The truth is, there's no single "best" lock among the many different types of locks on the market. A padlock that's perfect for a warehouse shutter would be useless on your bedroom door, and a heavy-duty mortise lock makes little sense for a kitchen drawer. The right choice depends on where the lock is going—a main door, an interior door, a sliding door, or even a piece of furniture—and how much traffic that door sees and what you're actually trying to protect.

Quick comparison: Types of Door Locks

List of Types Of Door Locks in india

Here's a practical, database-style breakdown of the ten most common types of locks for doors you'll come across in Indian homes and commercial spaces, plus a look at locks built specifically for sliding doors and drawers, along with where each one genuinely earns its place.

1. Padlocks

Padlocks remain one of the most familiar locks around, mostly because they're not fixed to anything—you can move them between a gate, a trunk, a shutter, or a storage unit as needed. That portability is exactly why they're everywhere: shop shutters, garages, warehouse doors, and two-way grill gates all rely on them.

Not all padlocks are created equal, though. If you're locking up something valuable—a storefront or a warehouse full of inventory—go for a shutter padlock built with hardened steel. The cheap ones you find at every corner store are fine for a garden gate, but they won't stop anyone determined to break in.

2. Deadbolts

If there's one lock worth spending extra on, it's the deadbolt—and that's precisely why it's the standard for main entrance doors across most homes. Its bolt extends deep into the door frame, which makes it far harder to force open than a spring-latch lock, and it can't be slipped or manipulated with a knife the way older knob locks sometimes can.

The single-cylinder deadbolt is the version you'll see most often. It's operated with a key from the outside and a simple thumb turn from the inside—straightforward, reliable, and easy for anyone in the house to use without training.

3. Doorknob Locks

Doorknob locks are the ones you grew up with—the lock cylinder is built right into the round or lever-shaped knob, and they're a staple on interior doors like bedrooms and bathrooms.

Here's the catch: they're convenient, but not particularly secure. A firm hit with a hammer or a heavy object can pop one open fairly easily. That's why security experts rarely recommend them alone for a front door—if you do use a knob lock on your main entrance, pair it with a deadbolt for actual protection. For internal doors where privacy (not security) is the goal, they're a perfectly reasonable, low-cost choice.

4. Mortise Locks

Walk into any commercial building, glass-front office, or high-end residential complex, and there's a good chance the main door is running a mortise lock. Unlike a surface-mounted lock, the mortise system is recessed into the door itself, with a rim cylinder and a box lock mechanism working together along the door's edge.

Mortise locks come in different lever configurations—three-lever and five-lever being the most common. As a rule of thumb, more levers mean more security, since each lever adds another point that has to be correctly aligned before the door opens. This is why mortise locks are the go-to for commercial entrances and doors that genuinely need to resist forced entry.

5. Lever Handle Locks

Lever handle locks trade the twist-and-turn motion of a knob for a simple push-down action, which makes them noticeably easier to operate—a real advantage in spaces designed for accessibility or for anyone carrying groceries with both hands full.

You'll typically find these on internal doors in offices and on bedroom or bathroom doors at home. They're not built for heavy-duty security, though, so keep them off your main entrance and reserve them for doors where ease of use matters more than resistance to force.

6. Electronic Locks

Electronic locks have moved from "futuristic gadget" to "standard fitting" fairly quickly, especially in offices, hotels, and increasingly, Indian apartments. Instead of a physical key, access comes via a keypad code, an RFID card, or—in newer models—a smartphone app that lets you unlock the door remotely.

They run on batteries or mains power, which does mean there's a maintenance side to consider (nobody wants to get locked out because the batteries died). But the upside is real: no more re-keying every time an employee leaves, no more spare keys under the doormat, and the ability to track who accessed the door and when.

7. Chain Locks

You've almost certainly used one of these in a hotel room without knowing its name. Chain locks aren't meant to stop a determined intruder—their real job is letting you crack the door open a few inches to see who's outside before you commit to opening it fully.

It's an old, low-tech idea, and it still works because it does exactly one thing well: it buys you a moment to check who's knocking. On its own, a chain lock offers minimal security, which is why it's almost always installed alongside a stronger primary lock. Families with young children also use them as an extra safeguard against toddlers wandering off unnoticed.

8. Euro Cylinder Locks

Euro cylinder locks are common on front gates and are often built into multi-point locking systems, where a single turn of the key engages several locking points around the door frame at once. Inside, a pin-and-tumbler mechanism lines up a set of pins that only your specific key can align correctly.

One underrated advantage: if the cylinder ever wears out or you want to upgrade your security, you can swap out just the Euro cylinder without replacing the entire multi-point mechanism. That makes ongoing maintenance and upgrades far cheaper than replacing the whole lock assembly.

9. T-Handle Locks

T-handle locks are built for one very specific job—vending machines and similar equipment—and they do it well. Pull the T-shaped handle, and the lock disengages; no fiddling with keys at odd angles.

The trade-off is that replacing a T-handle lock, once it's worn out or a key is lost, tends to be a slower process than swapping a standard cylinder. Still, for vending machines, utility cabinets, and similar low-security-but-frequent-access applications, they remain the standard choice.

10. Latch Locks

Latch locks are the classic spring-loaded mechanism you'll find on garden gates and screen doors. The bolt sits at an angle on the edge of the door; when you turn the handle, it retracts against spring pressure, and once you let go, the spring snaps it back out to catch the strike plate on the frame.

They're simple, inexpensive, and self-closing—genuinely useful for gates and secondary doors—but they're not a substitute for a proper lock on any door that needs real security.

Types of locks for sliding doors

Sliding doors—common on balconies, patios, and modern wardrobes—don't take a standard deadbolt or mortise lock, since there's no swinging door edge for the bolt to seat into. 

Because sliding doors are also vulnerable to simply being lifted out of their track, security experts usually recommend pairing a hook lock with an anti-lift bracket for real protection.

Instead, they rely on their own dedicated hardware:

• Hook locks—a curved bolt that hooks into the frame, making the door harder to lift off its track. The most common choice for aluminum and UPVC sliding doors.

• Flush bolts/foot bolts—mounted at the top or bottom of the door and manually slid into a hole in the track, often used as a secondary lock alongside a hook lock.

• Sliding door pin locks—a simple pin that stops the door from sliding open beyond a set point, useful as a ventilation-friendly partial lock.

• Electronic sliding door locks—increasingly used on balcony and patio doors in apartments, offering keyless entry with the same sensor-based mechanism as standard smart locks.

Types of locks for drawers and cabinets

Drawer and cabinet locks are built for low-force, low-traffic security — think of them as protecting privacy and contents rather than resisting a break-in attempt. The main types include

• Cam locks—the most common drawer lock, using a rotating cam that catches on the drawer frame when turned with a small key. Found in office desks and furniture across India.

• Plunger locks—a spring-loaded pin that automatically locks when the drawer is pushed shut, unlocked with a key or release button.

• Sliding bolt locks—a simple manual bolt for cabinets that don't need a keyed mechanism, often used for child-safety cabinet locks.

• T-handle locks (also covered above)—frequently used on filing cabinets and multi-drawer units, where a single handle locks several drawers at once.

How to choose the right lock

A few quick questions can narrow this down fast:

• Is this your main door? Go with a deadbolt or mortise lock—ideally both, paired together—since this is the door that carries the most security responsibility in your home.

• Is it an internal door (bedroom, bathroom, office)? A knob lock or lever handle lock is perfectly adequate.

• Is it a sliding door (balcony, patio, or wardrobe)? A hook lock paired with an anti-lift bracket, or an electronic sliding door lock for keyless convenience.

• Is it a drawer or cabinet? A cam lock for everyday furniture or a sliding bolt lock for simple child-safety needs.

• Do you want keyless access or remote monitoring? An electronic lock is worth the investment, especially for offices or rental properties.

• Is it a gate, shutter, or storage unit? A padlock or Euro cylinder lock, depending on whether it needs to be portable.

• Want an extra layer on an already-locked door? Add a chain lock—but never rely on it alone.
