How To Unlock A Locked Door?

Getting locked out of a room, your home, or even your office is something that happens to the best of us. Whether it's a forgotten key, a jammed lock, or a broken mechanism, it can be frustrating and stressful. But don't panic — this guide is here to help.

In this article, we'll walk you through everything you need to know about unlocking a locked door. We'll explore common causes, step-by-step solutions, and how to choose the right door lock to prevent it from happening again. Whether it's for security doors, home use, or commercial use, we've got you covered.

Plus, we'll highlight different types of door locks, like mortise locks, pocket door locks, barn door locks, and more, so you understand what you're working with — and what to look for when replacing or upgrading. Let's dive in.

Understanding Why Doors Get Locked (and Stay Locked)

Before we talk about how to unlock a door, it helps to know why it's locked in the first place. Here are the most common reasons people find themselves stuck outside:

• You lost or forgot the key.

• The key broke off inside the lock.

• The lockbody is jammed or faulty.

• The door lock components are rusted or misaligned.

• It's a digital or combination door lock, and the code isn't working.

• The door swelled due to humidity and won't release the latch.

• Someone locked it from the inside — and left through another exit.

Identifying the cause helps you choose the right method to unlock it without damaging the door.

Types of Door Locks You Might Be Dealing With

Not all doors are created equal — and neither are their locks. Understanding what kind of door lock you're dealing with can make the unlocking process easier. Here are some of the most common types:

Lock Type	Description	Common Use
Mortise Lock	A lock that fits into a deep pocket inside the door	Office doors, apartments, hotels
Pocket Door Lock	Designed for sliding doors that disappear into the wall	Bathrooms, closets
Barn Door Lock	Surface-mounted lock for sliding barn-style doors	Modern homes, farmhouses
Patio Door Lock	Typically found on sliding glass doors leading to outdoor areas	Homes, apartments
Magnetic Door Lock	Uses electromagnetism to secure doors	Commercial buildings, offices
Bedroom Door Lock	Usually a simple knob lock with or without a key	Homes
Sliding Glass Door Lock	Locks that secure glass doors that slide horizontally	Balconies, patios
Combination Door Lock	Uses a keypad instead of a key	Offices, smart homes
Double Door Lock	Meant for French doors or double-panel doors	Elegant entrances

Each lock type needs a different approach to unlocking. We'll talk about that next.

Quick Fixes: How to Unlock a Locked Door Without a Key

Sometimes you don't have tools or time to call a locksmith. Here are some emergency hacks you can try, depending on the type of door lock:

Use a Credit Card (Only for Spring Latch Locks)

This classic trick works best on interior doors with a spring-style lock (not deadbolts). Simply:

• Grab a flexible card you don't mind damaging.

• Insert it between the door and frame, just above the lock.

• Wiggle and slide downward while turning the handle.

This won't work on high-security locks or exterior doors, but it's worth a shot for a bedroom door lock or door lock for home use.

Try a Paperclip or Hairpin (For Simple Keyholes)

If you've got a lockbody with a basic keyhole, you may be able to pick it:

• Straighten a paperclip or bobby pin.

• Insert it into the keyhole and apply light pressure.

• Jiggle or twist until you hear a click.

This isn't easy and doesn't work on advanced locks like a magnetic door lock or a combination door lock, but it might help in a pinch.

Remove the Doorknob or Lockset

If you can access the screws:

• Use a screwdriver to unscrew the handle or lock plate.

• Pull off the knob and manually turn the locking mechanism.

• Open the door.

This works for many interior door locks, especially older models or cheap hardware.

When to Call a Locksmith

If the door refuses to budge or you're not sure what you're doing, it's best to call a professional. Locksmiths have tools to open even the most stubborn mortise locks, patio door locks, and sliding glass door locks without damaging the door.

Here's when to call for help:

• You're locked out of your home at night.

• The key broke off inside the lock.

• You're dealing with a high-security commercial door lock.

• The door is your only entry or exit (safety issue).

  
  

How to Prevent Getting Locked Out Again

Unlocking a door is only half the battle — let's keep it from happening again.

Upgrade to a Smart Lock

Digital door locks for home use are a game-changer. Options include:

• Keypad locks (no key needed)

• Smartphone-controlled locks

• Combination door locks with backup keys

  
  

GMB's digital smart lock series includes advanced options like:

• Smart handle locks

• Face recognition locks

• Smart deadbolts

• Electronic cylinders

These options are perfect for homeowners and business owners who want convenience and security.

Install a Double Door Lock or Deadbolt

If you're dealing with double doors, you'll want secure locks on both sides. A double door lock with a keyed deadbolt and latch system offers better protection and ensures you don't get locked out easily.

Keep Spare Keys Smartly

• Hide a key in a secure outdoor key box.

• Give a spare to a trusted neighbor or friend.

• Keep a backup key in your car or work bag.

Regular Maintenance of Lock Components

Lubricate your door lock components every few months. This keeps your lockbody from jamming and prevents rust buildup. Check alignment, screws, and handles.

Choosing the Right Lock for Your Door Type

Some doors need specific locks. Here's a breakdown:

Door Type	Recommended Lock
Sliding Glass Door	Sliding glass door lock, patio door lock
Barn Door	Barn door lock, surface latch
Pocket Door	Pocket door lock with privacy latch
Bedroom Door	Simple knob lock, magnetic door lock
French or Double Door	Double door lock, mortise lock with deadbolt
Office/Commercial Door	Mortise lock, high-security lockbody, electronic cylinder

Choosing the correct lock ensures better safety and ease of use. GMB offers a wide selection of locks based on material, function, and design.
