How To Lock A Door From The Inside

Locking a door from the inside is a simple yet crucial skill that everyone should know. Whether you’re staying in a hotel room, dormitory, or your own home, knowing how to lock a door from the inside can give you peace of mind and keep you safe. In this article, we will discuss various ways to lock a door from the inside to ensure your safety and security.

Types of Locks

There are several types of locks that you can use to secure a door from the inside. The most common types of locks are deadbolts, knob locks, and chain locks. Deadbolts are the most secure type of lock and can only be opened with a key from the outside. Knob locks are less secure as they can be easily picked or forced open. Chain locks are also less secure and can be easily broken with force. No matter what type of lock you have, it’s essential to use it properly to ensure your safety.

Using a Deadbolt

To lock a door with a deadbolt, first, make sure the door is closed properly. Then, insert the key into the lock and turn it clockwise until you hear a click. The deadbolt should now be engaged, and the door should be secure. If your deadbolt lock has a thumb turn on the inside, you can use it to lock the door from the inside instead of using a key.

Using a Knob Lock

To use a knob lock, turn the knob on the inside of the door until it clicks into place. This will engage the lock and prevent the door from being opened from the outside. However, knob locks are relatively easy to pick or force open, so it’s essential to use them in conjunction with a deadbolt or other types of locks.

Using a Chain Lock

Chain locks are the least secure type of lock, but they can still provide an extra layer of security. To use a chain lock, first, close the door properly. Then, attach the chain to the door frame, and slide the latch into the catch. This will prevent the door from opening fully, but it will not prevent someone from forcing the door open.


Q: Can I lock a door without a lock?

A: Yes, you can use a doorstop or wedge to prevent the door from opening. However, this is not a secure method and can be easily bypassed.

Q: Can I lock a door from the outside?

A: It depends on the type of lock you have. Some locks can be locked from the outside with a key, while others can only be locked from the inside.

Q: What should I do if the lock is broken?

A: If the lock is broken, you should contact a locksmith or your landlord to have it fixed.


Knowing how to lock a door from the inside is crucial for your safety and security. Whether you’re at home, staying in a hotel room, or living in a dormitory, make sure you use the appropriate type of lock and use it properly. Don’t forget to check the lock before you go to bed or leave the room to ensure that it’s secure. By following these simple steps, you can keep yourself and your belongings safe and secure.
