A lever handle lock and a baby proof door lock both stop toddlers opening doors, but they work in different places. A lever handle lock works on the handle itself, either by blocking the lever from being pressed down or by replacing the handle with one that locks. A top-of-door lock, like the GlideLok top-of-door childproofing lock, leaves the handle alone and secures the door high up, out of a small child’s reach.

Lever handle lock vs baby proof door handle lock

The key difference is where the lock sits. A lever handle lock sits at handle height and relies on a mechanism a toddler cannot work out or operate. A top-of-door lock sits above the handle, near the top edge of the door, and relies on height: a child simply cannot reach it.

That difference affects installation, how the door looks, which doors each suits and how easy it is for adults to use every day. GlideLok’s product is the top-of-door type, so if you want to lock a lever at handle height, you will be looking at a different kind of product.

How lever handle locks work

There are two common kinds:

Clip-on lever locks. These attach to the existing lever, usually with adhesive or a clamp, and stop it being pressed down unless an adult presses a release. They leave the handle in place and can usually be removed later.
Replacement lever handles with a lock. These swap out the handle for one with a built-in lock, such as a push-button privacy lock. They look like normal hardware but need the old handle removed and a screwdriver to fit.

A lever lock is handy on doors adults open many times a day, because the lock is right where your hand already goes. The downsides are that clever toddlers sometimes work out clip-on releases, adhesive can weaken over time, and a replacement handle is a bigger job and a bigger cost if you have many doors to secure.

If you are replacing a handle, check the backset (the distance from the door edge to the center of the handle). Most residential doors use a 2-3/8 inch or 2-3/4 inch backset, and door thickness also varies, so measure before you buy.

How top-of-door locks work

A top-of-door lock mounts at the top edge of the door, well above the handle. With the lock engaged, the door cannot swing open even if a child turns the handle. Because it does not depend on the handle, it works whatever handle you have, lever or knob.

Read the GlideLok top-of-door lock listing for how it attaches, whether it needs tools, which door thicknesses it fits and how you release it. GlideLok also sells a 2-pack extension rod as an accessory for the door top lock; check the listing to see whether your doors need it.

Top-of-door locks suit renters and anyone securing several doors, since they leave the handle untouched. The trade off is that shorter adults may need to stretch to reach the lock, and it is one more step every time you go through the door.

Which door gets which lock

Many homes end up with a mix. As a starting point, we suggest:

Pantry, laundry and storage closets: a top-of-door lock. These doors are opened less often, and the lock keeps cleaning products and small items away from little hands.
Home office or a room with hazards: a top-of-door lock, or a lever lock if the door has a lever and you open it all day.
Doors with knobs: a top-of-door lock, since lever locks will not fit.
Stairs and outside doors: use a lock that an adult can open quickly, and check the product is meant for that door.

Be careful with any lock on a room a child sleeps in. Never lock a child inside a room, and make sure every adult in the house can open any locked door quickly in an emergency, such as a fire.

Materials and durability

Check the materials on any listing. Clip-on lever locks are usually plastic and depend on their adhesive or clamp. Replacement handles are usually metal and last as long as normal door hardware. Top-of-door locks vary, so look at what the body and the latch are made of and whether the listing states the door thicknesses it fits.

Whichever you choose, test it a few times after fitting, and check it regularly. A lock that has worked loose, or adhesive that has started to peel, stops protecting anyone.

Our take and where to buy

If you want the lock at hand height on lever handles you use all day, look at lever handle locks. If you want one type that works on any door and handle and keeps the lock out of reach, a top-of-door lock such as the GlideLok door top lock is the simpler route.

Questions

Lever handle lock vs baby proof door handle lock: what is the difference?

A lever handle lock works on the handle, blocking it or replacing it with a locking handle. A top-of-door baby proof lock, like GlideLok's, leaves the handle alone and secures the door high up, out of a child's reach.

Does a top-of-door lock work on a door with a knob?

Yes. Because it secures the door rather than the handle, the handle type does not matter. Check the listing for the door thicknesses it fits.

Will a lever handle lock fit a round door knob?

No. Lever locks are made for lever handles. For knobs, use a knob cover or a top-of-door lock.

Do I need tools to fit these locks?

Clip-on lever locks usually do not. Replacement lever handles need a screwdriver. For the GlideLok top-of-door lock, check the listing for the fitting method.

Is it safe to lock a child's bedroom door?

We do not suggest locking a child inside a room. Every adult in the house should be able to open any locked door quickly in an emergency, such as a fire.
