Child proof door handle lock for a lever, not a stair

Updated: October 2026

A toddler has learned that a lever goes down, and the bedroom or the cupboard opens. You want a fix without a drill, often because you rent. The only product in the [room door lock comparison](/hub/door-and-window-security/room-door-lock) that does that job is the Moonybaby two-pack, a stick-on lock that blocks the lever. It buys time on a lever handle. It is not the bath, it is not the stairs, and it is not a tested standard unless the listing states one. This ASIN does not. Peter F. used the amazon.co.uk listing in October 2026, plus NHS and Which? guidance. A qualifying purchase can earn a commission at no extra cost to you.

What the two-pack actually blocks

The Moonybaby lock is about £7.99 for two, in ABS, fixed with acrylic foam tape. The listing says no tools. You press it under the lever so the handle cannot travel far enough to release the latch, and you free it with two buttons. A centre button is meant to stop the lock engaging by accident. The lock is shaped for a lever. A round knob does not give it a bar to sit under. The two-button release slows a toddler. It is not a claim that no child will copy you. BABYGO, a different brand, says some children learn a similar action, which is why medicines still belong out of reach. Reviews include adults who found the release awkward with one hand. The pack does not take a key, and it does not replace the latch. Sashlock sizes belong on the internal door lock buying guide.

What the reviews add

The file is 4.5 from 1,250 amazon.co.uk reviews. Reviewers say the tape holds for toddlers. A hard tug pulled one lock off. Removal marked the paint. Spare pads are not in the box. One buyer added extra glue after a child pulled a lock off. Another used a hairdryer to soften the tape. Press the pad onto clean, sound paint, and test it with the pull a child gives the handle. If it lifts, the lever works again. GOV.UK says a fire door must meet the frame. A handle so clogged that the latch no longer catches is a fire-door problem. The lmytdo slide bolt, the best-value Jelken at about £3.79, and the QWORK top pick are inside-only fasteners, not this lever lock. Who should skip which row is on the best bathroom door lock page.

Stairs and the bathroom are separate

A review describes using the Moonybaby lock at the top of the stairs. This page does not treat that as the control. Which? says a pressure-fit stair gate has a bottom bar and should not be the only barrier at the top of the stairs. Healthier Together keeps stair gates in the picture until at least the age of two, and says never to leave a baby or toddler in the bath. A handle lock does not supervise the water. If the child is inside, and the bathroom has a bolt they can reach, the stick-on lock on the landing handle does nothing. That choice is on the bathroom door lock page. A keyed bedroom handle can make the same trap.

What you still do after it is stuck on

Medicines and cleaning products stay up. BABYGO’s page claims EN 16948:2017 and EN 71-3 for BABYGO’s own lock. The Moonybaby listing does not state EN 16948. Do not copy that line across. Keep the stair gate if the stairs are the risk, and keep an adult at the bath. Use the lever lock where a push on the handle is the actual problem: a bedroom during a nap, a cupboard, a room you are working in. Test the two buttons while you are holding what you usually hold. If the door is a fire door and the residue stops it closing, clean it back until the latch meets the keep.

Common questions

Will a stick-on lock fit a round knob?
The Moonybaby pack is for a lever that moves down. A round knob does not give the lock a bar to block. Check the handle before you peel the tape. If every door is a knob, this two-pack is the wrong product.
Can my toddler learn the two-button release?
They might. Two buttons slow a small child, and a centre button only stops the lock engaging by accident. BABYGO warns that some children learn a similar action on their own lock. Treat this pack as a delay, and keep medicines and cleaners out of reach as well.
Does it need a drill?
No. The listing says no tools, and the fixing is acrylic foam tape. You are not cutting a mortice. That suits a rented door, as long as you accept marks when the pad comes off.
Will it mark the door when I take it off?
Reviews say it can. People mention paint marks and a hairdryer to soften the tape. Spare pads are not in the box. Peel slowly, and do not pile on extra glue if the door is a fire door that still has to close into the frame.
Can I use it at the top of the stairs instead of a gate?
No. A reviewer used it that way, and a lever lock does not close the stair. Which? says a pressure-fit gate should not be the only barrier at the top, and prefers a screw-fixed gate there. Healthier Together keeps gates in use until at least two.
Is the Moonybaby lock tested to EN 16948?
The listing does not say so. EN 16948:2017 appears on BABYGO’s page for BABYGO’s lock, with an EN 71-3 claim. Those sentences stay with that product. This pack’s evidence is the amazon.co.uk reviews, not a standard number.
