Families with children know the frustration of lost keys, kids forgetting them at school, or little ones struggling with fiddly lock mechanisms. A mechanical keypad lock solves all of these problems at once. Children learn a simple code rather than carry a key. Parents change the code in minutes if it gets shared too widely, and nobody gets locked out because there is no key to lose.
This page recommends five proven models from the Lockey Digital range, each suited to different family situations. All are 100% mechanical, require no batteries or apps, and are manufactured in Japan with Teflon-coated stainless steel internals for long-lasting, reliable performance.
Top 5 Digital Locks for Families with Kids
1. Lockey 2835 — Best All-Round Family Lock for Doors and Gates
The Lockey 2835 is the most versatile model in the range and the clear first choice for most family homes. It features lever handles on both sides, which are far easier for children to operate than knobs, especially when carrying school bags or with wet hands. The built-in passage function is particularly useful for families: switch it on during the day so children can come and go freely from the garden without entering a code, then disable it in the evening to restore full security.
The code uses a non-sequential system, meaning children press the correct buttons in any order after the clear button. This is easier for younger children to remember than a strict sequence, because they just need to know which buttons to press, not the exact order.
For families with a garden gate, the 2835 Gate Lock Adapter fits gate thicknesses from 44mm to 127mm with gate gaps of 10mm to 38mm. This makes it the standard choice for securing play areas, driveways, and side gates where children’s safety around roads is a concern.
- Code combinations: Over 8,000 groups
- Code length: 3 to 7 digits
- Material: Zinc-plated steel, Teflon-coated stainless steel internals
- Lever handles: Yes, both sides (easier for children than knobs)
- Passage function: Yes (code-free access when enabled)
- Holdback: Yes
- Fire rated: BS EN 1634-1:2014 with intumescent kit
- Door thickness: Up to 55mm (standard kit)
- Warranty: Lifetime mechanical
- Price: From approximately £135.60 inc. VAT
2. Lockey 2435 — Best for Front and Side Doors
The Lockey 2435 is a compact, proven lock well-suited to front doors, side doors, and utility entrances that children use daily. It features a knob on the outside and a lever on the inside. The inside lever means children exiting the house never need to enter a code — they simply turn the lever and go, which is important for fire safety and for young children who may not yet have memorised the code.
The holdback facility is handy for families during busy periods: push the internal snib and the latch stays withdrawn, allowing the door to open freely without code entry. Release it to restore security. Over 7,000 possible code combinations mean plenty of scope to choose a code that your family can remember easily.
The 2435 has been fire-tested to BS EN 1634-1:2014 with the Lockey intumescent kit, making it suitable for fire-rated timber door sets — relevant if your front or internal fire doors require compliant hardware.
- Code combinations: Over 7,000 groups
- Code length: 4 to 6 digits
- Material: Zinc-plated steel, Teflon-coated internals
- Outside handle: Knob
- Inside handle: Lever (no code needed to exit)
- Holdback: Yes (via internal snib)
- Fire rated: BS EN 1634-1:2014 with intumescent kit
- Door thickness: 35–55mm
- Warranty: Lifetime mechanical
- Price: From approximately £112.20 inc. VAT
3. Lockey 2435K — Best When Parents Want a Backup Key
Families with very young children sometimes want the reassurance of a physical key as backup. The 2435K is identical to the standard 2435 but adds a euro-profile key override cylinder. This means the door can be opened either by code or by key, giving parents a fallback option if a young child cannot manage the keypad.
The key override is also useful for landlords with families renting, or for situations where a grandparent or babysitter prefers using a key. The cylinder comes in keyed-different or keyed-alike options, so if you have multiple 2435K locks across different doors, one key can work on all of them.
- Code combinations: Over 7,000 groups
- Code length: 4 to 6 digits
- Key override: Euro-profile cylinder (keyed differently or keyed alike)
- Inside handle: Lever (no code needed to exit)
- Holdback: Yes
- Fire rated: BS EN 1634-1:2014 with intumescent kit
- Door thickness: 35–55mm
- Warranty: Limited lifetime (key override models)
- Price: From approximately £159.60 inc. VAT
4. Lockey 1150 — Best for Heavy-Traffic Family Entrances
If your front door gets hammered with constant use — kids coming and going, school friends, after-school clubs, deliveries — the 1150 is built for it. This heavy-duty lever lock is designed for 80 to 100 operations per day, far exceeding what even the busiest family household will demand. That over-engineering translates directly to longevity in a family setting.
Like the 2835, it features lever handles on both sides and both holdback and passage functions. The heavy-duty construction means it can handle years of enthusiastic use by children without the mechanism loosening or wearing out.
- Code combinations: Over 7,000 groups
- Lock type: Heavy-duty lever latch
- Passage function: Yes
- Holdback: Yes
- Fire rated: BS EN 1634-1:2014 with intumescent kit
- Warranty: Lifetime mechanical
- Price: From approximately £228.00 inc. VAT
5. Lockey 2430DS — Best for Garden Gates and Play Area Security
Keeping young children safe in gardens, especially near roads or driveways, requires a gate lock that works from both sides. The 2430DS has a keypad on both the inside and outside of the gate, requiring a code to open from either direction. This prevents toddlers from wandering out while still allowing authorised access from the street side.
Each keypad operates independently, so you can set different codes if needed. The lock does not include a holdback facility, meaning the gate always requires a code to open, exactly what you want when preventing unsupervised access by young children.
- Code combinations: Over 7,000 groups per side
- Lock type: Double-sided keypad (code in / code out)
- Holdback: No (always secured — ideal for child safety)
- Fire rated: BS EN 1634-1:2014 with intumescent kit
- Warranty: Lifetime mechanical
- Price: From approximately £250.80 inc. VAT

Why Keyless Entry Works Well for Families
The practical benefits for families with children go beyond simply not having to carry a key.
- Children as young as five or six can learn a keypad code. Lockey mechanical codes are non-sequential, so a child just needs to remember which buttons to press, not the order. Pressing C, then the correct buttons in any order, then operating the handle is a simple routine that children master quickly.
- No key to lose, damage, or copy. Lost keys are one of the most common household frustrations for families. A single locksmith callout to deal with a lost key costs £50 to £100 or more. A keypad lock eliminates this expense permanently.
- Code changes take minutes and cost nothing. If your child shares the code with a school friend or you suspect it has become too widely known, you can change it yourself by rearranging the internal tumblers. There is no locksmith fee and no limit on how many times you change the code.
- No batteries to fail. All models recommended above are 100% mechanical. There is no risk of being locked out because a battery died, which is particularly important for families who rely on their children being able to get into the house after school.
- The passage function on the 2835 and 1150 adapts to your family’s day. Enable passage mode during after-school hours so children can move freely between the house and garden without entering a code. Disable it in the evening to restore full security. This flexibility suits the rhythm of family life far better than a lock that is either always locked or always unlocked.
Features That Matter Most for Families
- Lever handles vs knobs. Lever handles (available on the 2835, 1150, and inside the 2435/2435K) are much easier for children to operate, especially with wet or cold hands, when carrying bags, or when in a hurry. If your household includes younger children, prioritise a model with lever handles on at least the inside.
- Exit without a code. On single-sided models like the 2435 and 2835, the inside handle always operates freely without entering a code. This is essential for fire safety and means even the youngest family member can exit the house without assistance.
- Holdback facility. The holdback on the 2435, 2435K, 2835, and 1150 lets you keep the latch withdrawn so the door opens freely without any code entry. This is useful during children’s parties, when unloading shopping with a pushchair, or during any period where constant code entry would be impractical.
- Double-sided locking for gates. The 2430DS requires a code from both sides, preventing children from opening the gate unsupervised. This is the safest option for garden gates adjacent to roads, driveways, or any area where unsupervised child access is a concern.
- Protective clutch mechanism. The knobs and handles on Lockey 2000 Series locks include a slipping clutch that prevents damage if forced. This is a practical detail for families, because children (and their friends) are not always gentle with door hardware.
Installation Tips for Family Homes
Every Lockey lock ships with a drilling template, all required hardware, and step-by-step instructions. A competent DIYer can complete most installations in under an hour.
- Measure your door thickness and backset before ordering. The 2435 and 2435K suit doors of 35 to 55mm thick with a 60mm backset (adjustable to 70mm). The 2835 suits doors up to 55mm with an adjustable backset. Getting these measurements right ensures a smooth fit.
- For gate installations, the 2835 Gate Lock Adapter is purpose-built for timber and metal gates. It accommodates gate thicknesses from 44mm to 127mm and gate gaps from 10mm to 38mm. The adapter housing is made of glass-filled nylon, which is strong, weather-resistant, and rust-resistant.
- Position the lock at a height accessible to your children. The standard lock height is around 1 metre above ground. If your youngest child is particularly small, consider whether they can comfortably reach the keypad. For gate locks, you may need to position slightly lower than standard.
- Use stainless steel fixings for outdoor installations to prevent rust from weakening the mounting over time.
- Test the code thoroughly with your children before relying on the lock. Have each child practise the sequence multiple times with the door open. Make sure they understand the C (clear) button must be pressed first.
Choosing a Code Your Children Can Remember
Lockey mechanical codes use the buttons numbered 0 to 9, plus X and Z (on the 2835) or additional buttons on 2000 Series models. The code is non-sequential, so a child pressing 3, 7, 1 achieves the same result as pressing 1, 3, 7.
Choose a 3- to 4-digit code for younger children. Shorter codes are easier to memorise while still providing good security from the thousands of available combinations. Avoid obvious patterns like 1234 or your house number.
A useful technique for younger children is to create a visual pattern on the keypad rather than asking them to remember numbers. For example, three buttons that form a diagonal line or an L-shape are easier for a child to recall than three random numbers.
You can extend the code to 5, 6, or 7 digits as children grow older and can handle longer combinations. Changing the code is free and takes only a few minutes.
Fire Safety and Building Regulations
Several of the recommended models have been fire tested to BS EN 1634-1:2014 and BS EN 1363-1:2012 when fitted with the Lockey intumescent kit. This applies to the 2430, 2435, 2435K, 2430DS, 2835, and 1150, making them suitable for 30- and 60-minute fire-rated timber door sets.
The intumescent kit is required for fire compliance. Without it, even a fire-tested lock does not meet the standard. If your door is fire-rated, order the intumescent kit with your lock.
All single-sided Lockey locks allow free exit from the inside without a code, which meets the Building Regulations requirement for unimpeded escape. The inside lever or thumbturn operates the latch directly, so no one — including young children — can become trapped inside.
Maintenance for Busy Households
Mechanical Lockey locks need very little upkeep, which suits busy family life well.
Wipe the keypad with a damp cloth periodically to remove dirt, sticky fingerprints, and grime — all inevitable in a household with children. Do not use harsh chemical cleaners.
If buttons feel stiff, clean the keypad face first. Most stiffness is caused by dirt rather than mechanical wear. If an external moving part feels tight, apply a small amount of silicone-based lubricant. Never use oil-based lubricants, which attract dirt and can damage the Teflon coating.
Check mounting screws once or twice a year, especially on gate-mounted locks, where wind and vibration can gradually loosen fixings.
The adjustable latch and spindle are consumable parts and may eventually need replacement after years of use. Replacements are available from Lockey Digital UK at minimal cost.
Frequently Asked Questions
What is the best door lock for a family with kids?
A mechanical keypad lock with lever handles is the best choice for most families. The Lockey 2835 combines lever handles on both sides, a passage function for code-free access during the day, over 8,000 possible code combinations, no batteries, and a lifetime mechanical warranty. Children as young as five or six can learn the non-sequential code, and parents can change it in minutes at no cost if it becomes compromised. For families who also want a backup physical key, the Lockey 2435K adds a euro-profile key override cylinder.
Are keypad locks safe for children?
Yes. Single-sided Lockey mechanical locks always allow free exit from the inside without entering a code, so children cannot become trapped. The inside lever or thumbturn operates the latch directly. The passage function on the 2835 and 1150 allows the door to operate completely freely during the day when children are moving in and out. For garden gates where you want to prevent children from opening the gate unsupervised, the 2430DS requires a code from both sides, which is the safest arrangement near roads or driveways.
Are keypad locks as safe as key locks?
Mechanical keypad locks from quality manufacturers are bump-proof and pick-proof because they contain no cylinder. They match or exceed the physical security of standard keyed locks. The additional advantage for families is that there is no key to lose, copy, or steal. If a code is compromised, changing it takes minutes and costs nothing, whereas rekeying a traditional lock requires a locksmith visit costing £60 to £120. Several Lockey models are fire tested to BS EN 1634-1:2014, demonstrating compliance with UK safety standards.
What locks do police recommend?
UK police generally recommend locks that meet recognised British Standards for resistance to picking, drilling, and forced entry. Mechanical keypad locks are inherently pick-proof and bump-proof because they have no pin-tumbler cylinder. For front door security, pairing a Lockey latch lock (such as the 2835 or 2435) with a Lockey deadbolt (such as the 2210) provides a two-lock arrangement that offers strong physical security. Always check with your insurer, as acceptance of keypad locks varies between providers.
