Baby Door Locks

Baby door locks are an essential part of baby proofing your home and should be used as soon as baby is mobile.  A curious child has a knack of getting into places they shouldn't and since they aren't old enough to understand the dangers it's important to prevent access to some areas in your home.

All locking devices aren't created equal but they all have the same purpose and that's to prevent your baby from opening a door and being injured by what's in the room or hurt themselves on the moving parts of a door.  Hinges and doors are unfortunately a common place for baby's to pinch fingers and we're here to help with that too!

Since it's not practical to use a baby gate in every room or area that presents a hazard to your baby, door locks can be a saviour.  The good thing is that there are are many options available but it can be difficult to find the right product.  We'll discuss the different options so you get it right the first time and prevent injuries.

You probably have a few questions about baby door locks and if you are like most parents this will be the first time you have used them. 

  • Is the device foolproof and will my baby figure out how to use it?
  • How difficult is the lock to install?
  • Is the lock going to leave permanent marks when we remove it?

If you haven't already done so be sure to read our baby gate safety page with some excellent information about baby gates for indoor use that can be used in tandem with locks for an added layer of safety. 

Where should I use Baby Door Locks?

A lock should be used on any door that if baby was to get into the room they could injure themselves or at least cause a bit of destruction!  Unfortunately most parents don't consider locking doors until it's too late but we commend you if you are reading this before your baby is up and about. 

The places you should consider baby door locks around the home are:

  • Bathroom
  • Laundry room
  • Bedrooms
  • Doors leading outside the home
  • Closets

A door that can't be opened by your baby will add peace of mind and one less thing to worry about.  All babies are different but one common theme is they are curious and they will catch you off guard - more than once!

1.  Door Lock and Pinch Guard

A baby door lock combined with a pinch guard is any parents dream and we know your baby would thank you if they could!  The Door Monkey is a great option that looks a little different but it really does the job well.  The "tail" catches on the door frame to prevent the door from opening and the bracket that attaches to the door itself prevents little fingers getting pinched.

  • Only works on standard square moulding

This device is recommended for anyone with standard doors because it works and is easy for parents to use.  If you don't mind the appearance you can't go wrong with this product. 

2.  Multi Use Latches and Straps

Multi use straps and latches are a great option for interior doors like the laundry room, bathroom or pet room.  If you need a door kept partially open to let air circulate or a pet through but not baby or children - this is a great option. 

The straps are attached with an adhesive to the door and frame and can be adjusted to allow just the right amount of space.  

door lock straps


  • Very easy to install
  • No drilling or measuring required
  • Versatile and can be used to baby proof drawers, cabinets and appliances
  • Easy to use


  • Adhesive works best on smooth surfaces and can leave marks when removed

If you have an interior door that you need to leave open whether its to allow pets in and out or want to allow air circulation throughout your home these are perfect. 

3.  Bi-Fold Closet Door Lock

A bi-fold or closet door can easily get overlooked but they do present hazards including finger pinching.  They present a unique challenge to lock and this simple product does the trick. It works by sliding over the fold to prevent opening and by simply sliding they allow the doors to open. 

bi-fold closet door lock


  • Easy to install and use
  • Simple design
  • Clean and tidy appearance
  • Works on standard width closet doors


  • Can be difficult to slide on thicker doors
  • Is a bit flimsy and can break over time

If closets are a concern this product is ideal and very easy to use.  It's worth considering if you want to take the extra step to create a complete baby safe home. 

4.  Finger Pinch Guard

A finger pinch guard is a simple and effective product and an easy way to prevent those accidental finger pinches that unfortunately happen when children first learn how to use doors.  A finger pinch guard won't prevent baby's or children from getting in a room but they will help prevent injury.

finger pinch guards


  • Affordable 
  • Simple
  • Easy to use
  • Effective
  • Colorful and fun options available


  • They can fall off with repeated use
  • Needs to be removed to close door fully

Pinch guards are a great arsenal in your overall baby door locks regime and are even available in fun shapes including colorful cartoon animals.  They can be hung on the door knob when the door needs to be close completely. 

5.  Door Knob Cover Lock

Door knob locks and covers have been around for many years and are still a decent option for parents of baby's and young toddlers.  They are designed to easily snap over existing round door knob handles and prevent children from turning the knob and opening the door.  They do however have some shortcomings that you should consider.

door knob cover lock


  • Easy to install
  • No hardware required or damage to door
  • Easy to use (possibly too easy)
  • Ideal for external doors that need to kept shut


  • Some children can figure out how to operate
  • Can only be used on round door knobs

This style of lock is effective but can be figured out by children and should not be relied on for complete safety and security.  Many parents have reported that their child has figured out how to operate this style of device so if you do decide on this device we caution against the reliability for some children. 

As an added safety device for external baby door locks we recommend a deadbolt lock that will discuss further in this article. 

6.  Lever Handle Baby Door Locks

A lever handle lock is an option for doors with lever style handles instead of the standard round ones.  This style of handle has grown in popularity in recent years because of their style and ease of use but unfortunately they are also easier to operate for babies and small children.  

A couple varieties include a device similar to round knob covers that snaps over the lever and a device shown in the picture that fits around the lever - both work good but do have some limitations.  

lever handle lock


  • Easy for parents to operate
  • Works well on some handles depending on size and shape


  • Only works on swing-out doors with proper hardware spacing
  • Locking required every time it's used and can be forgotten
  • Some parents report device doesn't adhere strong enough 
  • Some models require screwing into door which will leave holes after it is removed

If you have a lever style handle you are limited in devices that fit on or around the handle.  If you choose this option you are taking a chance on whether it works as advertised.  There are many other baby door locks available that can be used in tandem with or in place of this product. 

7.  DeadBolt Lock

A deadbolt lock is perfect for an additional safety measure on main exterior doors that are equipped with an extra locking mechanism.  Exterior doors sometimes get forgotten by parents but should be considered because adventurous children will be curious about what's outside.  

These devices are pretty simple to install and for the extra safety they provide they are worth serious consideration.  If they are used in tandem with a door knob or lever lock you can be assured you are doing everything you can to keep baby's and children safety inside the home.

  • Effective safety device
  • Easy to install
  • Easy to operate for parents

  • Some deadbolts can be difficult to install dependant on spacing from edge of door
  • Seniors may find this door lock difficult to operate

This is an overall great option for added peace of mind and safety for your home.  If baby proofing is a concern this is a great addition to baby door locks.

8.  Lock for In-Swinging External Doors

External doors present a unique and real hazard for baby's and children.  If you have ever experienced your child missing from home you can relate to the fear and sense of helplessness.  The home presents dangers for children but that gets magnified if an adventurous and curious child escapes outside without supervision.  

Adding an extra safety device to external doors is highly recommended and although it can be a hassle to operate an extra lock it is worth it and over time it will become second nature.  The Door Guardian from Cardinal Locks is excellent for doors that are flush with the door frame and provide a reliable and trusted safety lock.
