Magnetic vs adhesive strap cupboard locks: which should you choose?

Somewhere between crawling and walking, most babies discover that cupboard doors open. And the things we keep in low cupboards are often the things children should never get hold of.

This guide compares magnetic locks and adhesive straps honestly, using official advice from the NHS, the HSE Child Safety Checklist and RoSPA on what actually needs locking away.

The short answer: magnetic locks are hidden and harder for toddlers to figure out, but you need the key every time. Adhesive straps are quick for adults and fit almost anything, but your child can see them. Many families end up using a mix of both.

Why lock cupboards at all?

The NHS notes that medicines are the most common cause of hospital admissions for poisoning in under-5s, and that liquid laundry and dishwasher capsules and tablets can also cause poisoning. They're often packaged in bright, child-friendly colours. Here's what official advice says should be kept out of reach (our guide to hidden hazards at home goes further):

• Medicines, vitamins and supplements. The HSE advises keeping them in their original containers in a high, locked cupboard. RoSPA recommends locking medicine away even if it has a child-resistant cap.
• Cleaning products, laundry pods and dishwasher tablets. The HSE and RoSPA both advise storing them high up in a locked cupboard, in their original containers. The NHS says to keep cleaning products high up, and if that isn't possible, to fit safety catches to low cupboard doors.
• Knives, scissors and breakables. The HSE recommends safety locks on the cupboards and drawers where these are kept.
• Appliances. The HSE advises keeping the dishwasher, washing machine and dryer closed and using safety locks, and using fridge and freezer locks if there's food or drink your child shouldn't get to.

High and locked comes first. Official advice is clear that the strongest option for medicines and chemicals is a cupboard that is both high up and locked. A lock on a low cupboard is a useful backup, not a replacement for moving dangerous things up and out of reach. The NHS also reminds parents that child-resistant packaging only slows children down.

How magnetic cupboard locks work

A magnetic lock fits inside the cupboard, with a latch on the back of the door and a catch on the frame. When the door closes, the latch holds it shut. To open it, you hold a magnetic key against the outside of the door, over the lock, and the latch releases. From the outside, nothing is visible.

Pros

• Hidden from view. There's no strap or button for a toddler to see, pull or copy you opening.
• Your kitchen looks the same. Handy if you'd rather not have locks on show.
• No drilling with adhesive versions, which fix inside the cupboard with adhesive pads and usually come with an applicator tool to line the parts up.

Cons

• You need the key every time. Fine for occasional cupboards, tiresome for one you use ten times a day.
• Lose the key and you're locked out until you find it. Keep the key in the same high spot every time, and consider buying a spare key at the start. Spare keys are usually sold separately.
• Fitting takes a little more care. The latch and catch need to line up exactly, and you're working inside a cupboard. Check the maker's guidance on door thickness and material before you buy.

How adhesive cabinet straps work

An adhesive strap fixes across the outside of the door and frame (or two doors, or a lid and its base) with an adhesive pad at each end. The strap holds the door closed, and an adult releases it by hand with the strap's catch or clip, with no key needed.

Pros

• Quick for adults to open, with no key to keep track of.
• Fits almost anywhere flat. Because the strap is flexible and adjustable, it works on fridges, freezers, toilet lids, drawers, appliances and side-by-side doors, as well as ordinary cupboards.
• Fast to fit, with no drilling and nothing to line up inside the door.

Cons

• They're visible. A strap is something to look at and play with, and it changes how your units look.
• Older toddlers may work them out. RoSPA points out that young children copy grown-ups, so a determined two or three-year-old may eventually learn to open some straps.
• The adhesive needs time. Straps rely on a good bond, so they need careful fitting and time to set before use.

Other types worth knowing about

• Multi-locks are short, flexible adhesive locks for corners, appliances and doors where a long strap won't fit.
• Sliding locks slot through a pair of knob or loop handles on side-by-side doors. No adhesive, but they only work if your handles are the right shape.
• Drawer catches fit inside a drawer and let it open a short way before catching. An adult pushes down on the catch to release it.

Magnetic locks vs adhesive straps at a glance

	Magnetic locks	Adhesive straps
Visibility	Hidden inside the cupboard	Visible on the outside
Opening for adults	Needs the magnetic key every time	Quick release by hand, no key
Where it fits	Standard hinged cupboard doors and drawers	Cupboards, drawers, fridges, toilet lids, appliances and other flat surfaces
Fitting time	Longer, as parts need to line up inside the door	Shorter, but the adhesive needs time to bond
Good for	Cupboards holding the riskiest items, and those you open less often	Everyday cupboards, appliances and awkward spots

Which rooms suit which?

• Kitchen, under the sink. (See our full kitchen baby-proofing guide.) Ideally, move cleaning products and dishwasher tablets up high first. If something has to stay low, a hidden magnetic lock is a good fit here, as it gives a curious toddler nothing to work at.
• Kitchen, everyday cupboards and drawers. For pots, food and the cutlery drawer, straps or drawer catches can be easier to live with, since you're in and out all day.
• Fridge, freezer, dishwasher and washing machine. Straps or multi-locks, which fit the flat fronts and seals of appliances more easily than locks made to sit inside a cupboard.
• Bathroom. A strap on the toilet lid, and a magnetic lock on a vanity cupboard holding cleaning products or razors. Medicines belong in a high, locked cupboard.
• Living room and utility room. TV units, sideboards and utility cupboards often have odd handles or glass doors, so check what fits before you buy.

Fitting adhesive locks properly

Adhesive locks rely on a good bond. Whichever type you choose:

1. Clean the surface to remove grease and dust, especially in the kitchen.
2. Let it dry completely.
3. Choose a smooth, flat spot. Textured, flaking or uneven finishes won't give a good bond.
4. Check the position by opening and closing the door before you peel off the backing.
5. Press firmly and hold for the time the instructions give.
6. Leave it to bond. Follow the maker's instructions; for adhesive cabinet straps like ours, that's 24 to 72 hours before you start opening and closing the door.
7. Test it before you rely on it, and check it again every few weeks.

Review your locks as your child grows

The right setup at 8 months may not be right at 3 years. Walk round your home again at each new stage:

• Crawling (around 6 to 12 months). Low cupboards and drawers come first.
• Pulling up and climbing (around 1 to 2 years). Higher cupboards come within reach, especially with a chair or step nearby. Check that "high" is still high enough.
• Watching and copying (around 2 to 4 years). If your child has learned to open a strap, swap it for a magnetic lock or move the contents higher. Keep magnetic keys well out of sight, as children notice where you put them.

Adhesive can loosen over time with heat, steam and constant use, so check every lock regularly and refit any that feel loose.

Our take

There's no single right answer. Magnetic locks suit the cupboards that matter most and that you open least. Straps suit appliances, toilets and the cupboards you use all day. Whichever you choose, no lock and no home can be made completely risk-free, and nothing replaces watching your child. Store medicines and chemicals high up and locked first, then use cupboard locks as the extra layer they're designed to be.
