Sliding patio doors are one of the most targeted entry points in UK homes, yet many are still protected by nothing more than a basic latch. If you are looking for a keyless, battery-free way to secure yours, a mechanical push-button lock is the most practical solution available. This page ranks the top five Lockey Digital models for patio installations, explains what makes each one a good fit, and covers the key buying considerations when choosing hardware for exposed, outdoor-facing doors.
Top 5 Digital Locks for Patio Doors
Choosing the right keypad for a sliding or hinged patio entrance depends on the frame material, how the panel moves, and what level of protection you need. Below are five Lockey Digital models ranked by their suitability for typical UK patio setups, from purpose-built sliding options to versatile alternatives that work on side-hinged conservatory entrances.
| Model | Best For | Bolt Type | Frame Compatibility | Key Override Option |
| Lockey 2500 | Sliding patio doors | Surface hook bolt (20 mm throw) | Timber, aluminium, UPVC | Yes (with LD2000 adaptor) |
| Lockey LD950 | Narrow-stile aluminium sliders | Mortice hook bolt (22 mm throw) | Narrow aluminium & steel | Via 2210/2430DS keypad pairing |
| Lockey 2200 | Narrow frames & double-rebated panels | Surface rim sliding bar (57 mm throw) | All standard frame types | No |
| Lockey 2210 | Hinged patio & conservatory doors | Mortice deadbolt (25 mm throw) | Standard timber & UPVC | Yes (with LD2000 adaptor) |
| Lockey LC150 | Lightweight sliders & serving hatches | Surface hook bolt (compact) | Cabinets, closets, light sliding panels | No |
1. Lockey 2500 Hook Bolt
The Lockey 2500 is the standout choice for most residential sliding patio installations. Its surface-mounted hook bolt delivers a 20 mm throw that wraps laterally around the frame member, providing the engagement needed to resist lifting and prying on a sliding glass panel. Where a traditional deadbolt pushes straight out from the edge, a hook bolt grabs the frame from underneath. That difference matters more than most people realise.
Built from zinc-plated steel with Teflon-coated internal components, the 2500 handles rain, humidity, and temperature swings without the corrosion issues that plague cheaper alternatives. It fits wooden, aluminium, and uPVC frames, and the standard 14-button keypad provides over 7,000 possible code combinations. Installation is straightforward because everything ships in the box. No additional parts, no specialist tools. The satin chrome finish is recommended for outdoor use, which covers virtually every patio scenario.
One thing worth mentioning: the 2500 requires manual throw-back to re-lock after you open it. That is typical of mechanical sliding hardware, though, and it becomes second nature within a day or two. For properties where a key bypass is needed alongside the code, you can pair it with the LD2000 Key Override Adaptor.
2. Lockey LD950 Mortice Hookbolt
For narrow-stile aluminium patio frames where surface-mounting is not ideal, the Lockey LD950 is the heavy-duty option. This mortice hookbolt lock case sits inside the frame rather than on its face, giving a cleaner look while delivering serious holding power. The five-ply laminated steel bolt with a hardened pin offers 22 mm of throw, which provides a strong mechanical advantage against forced entry.
The LD950 is designed to retrofit with the Lockey 2000 series keypads, specifically the 2210 and 2430DS models. It uses a 28 mm backset, making it compatible with frames previously fitted with Adams Rite-style cylinders. If you are replacing keyed cylinder access on a commercial-grade aluminium slider, this is the natural upgrade path. The lock case dimensions are compact at 176 mm x 25 mm x 44 mm, fitting neatly into narrow profiles that reject bulkier hardware.
What I particularly like about this model is the option to pair it with the GB950 weldable steel gate box for external sliding gate applications as well. So if your property has both a patio entrance and a side gate, you can run a consistent system across both.
3. Lockey 2200 Surface Rim
The Lockey 2200 uses a surface rim-mounted sliding bar with a 57 mm throw rather than a hook bolt. Why does that matter for patio applications? The sliding bar can be fitted as close to the edge of the frame as you need, making it a strong candidate for double-rebated doors or narrow profiles where a standard mortice latch simply will not fit.
The bar retracts when you enter the correct code on the external knob, and an internal thumbturn allows free exit at any time. It shares the same 14-button keypad, Teflon coating, and over 7,000 code groups as the rest of the 2000 series. Finishes include satin chrome, bright brass, and jet black, so matching your existing handles and hinges should not be an issue.
Available in a non-handed configuration, the 2200 works on left or right-opening panels without modification. For homeowners dealing with awkward frame widths or older conservatory installations where standard mortice locks are problematic, this model often solves the puzzle. Do keep in mind that it requires a manual throw-back to re-engage the bar after unlocking.
4. Lockey 2210 Mortise Deadbolt
Not every patio entrance is a slider. If yours is a hinged French-style or side-opening conservatory arrangement, the Lockey 2210 gives you a mortice deadbolt with a stainless steel core shaft that cannot be cut. The 25 mm bolt throw sits within a 60 mm backset (with an adjustable 60/70 mm version arriving soon), and the deadbolt retracts by turning the external knob after entering your code.
This model works well as a secondary security measure on doors that already have a multipoint mechanism but need an additional layer of protection. It is also a solid primary locking solution for lighter conservatory entrances where the original hardware has worn out. The free-spinning core shaft is a detail that matters; it prevents anyone from gripping the bolt with tools and forcing it back.
Like other 2000 series models, the 2210 is non-handed and compatible with the LD2000 Key Override Adaptor. That means you can add a keyed backup without changing the core installation, which is useful for landlords or property managers who need emergency access.
5. Lockey LC150 Hook Bolt
The LC150 is the most compact option in the Lockey sliding range. At just 127 mm x 30 mm, it was originally designed for cabinets and lockers. Still, it works surprisingly well on lightweight sliding panels, serving hatches, and internal partition sliders that lead to garden rooms or covered patios.
Installation requires drilling only three holes, and the absence of a C-to-clear button keeps the profile minimal. Clearing the code is done by turning the front thumbturn instead. The surface hook bolt can be positioned as close to the panel edge as required, and the satin chrome finish blends with most residential fittings.
Where this model fits into the patio conversation is in smaller-scale scenarios: a sliding window between the kitchen and outdoor dining area, a garden office partition, or a utility room opening onto an enclosed terrace. It is not intended for full-sized, heavy glass sliders, but for everything else, it is an affordable, fuss-free choice.
Choosing the Right Lock for Your Setup
Frame Material and Bolt Compatibility
The first consideration is always what your patio frame is made from. Aluminium, timber, and uPVC each behave differently when drilled in, and they tolerate different mounting approaches. Surface-mounted models like the Lockey 2500 and 2200 are forgiving across all three materials because they fix onto the face of the frame rather than inside it. Mortice options like the LD950 need a routed pocket within the stile, which is straightforward on aluminium and timber but requires more care on uPVC to avoid cracking.
Sliding panels specifically need lateral-engagement hardware. A standard deadbolt that extends perpendicular to the edge of the frame does very little to prevent someone from lifting the panel off its track. That is why hook bolts exist; they curve around the keep and physically hold the sliding section against its track. If your patio uses sliders, prioritise the 2500 or LD950 over a conventional bolt.
Weather Resistance and Finish Selection
Every model in the Lockey 2000 series is rated for both internal and external use, but finish selection still matters. The satin chrome option is consistently recommended for outdoor-facing installations because it resists tarnishing from rain, UV exposure, and temperature cycling better than brass or jet black alternatives. Lockey uses zinc-plated steel construction across the range, and the Teflon-coated internals reduce friction even when moisture finds its way into the mechanism.
For coastal properties, where salt spray accelerates corrosion, periodic maintenance is worth the effort. A light application of silicone-based lubricant to the keypad buttons once or twice a year keeps everything operating smoothly. Annual checks on frame engagement points, bolt travel, and the strike plate ensure that gradual wear does not compromise security over time. These are simple tasks that require no specialist knowledge and considerably extend the working life of any mechanical system.
Code Management for Shared Access
One of the genuine advantages of a mechanical keypad over a traditional keyed mechanism is how easy code changes become. Every Lockey 2000 series model supports over 7,000 code groups when using combinations of three to seven digits. Changing the code takes minutes and requires no locksmith visit.
This is particularly valuable for holiday lets, Airbnb properties, or households where access needs to be shared with cleaning staff, gardeners, or tradespeople. After each guest or contractor period, you update the combination and move on. No keys to collect, no cylinders to replace. The Lockey 2435 model, which sits in the same 2000 family, even supports keyed-different override, meaning management can carry a physical override across multiple installations without needing to memorise every code.
For those who want the convenience of code entry plus a physical backup, the LD2000 Key Override Adaptor retrofits behind the existing keypad on compatible models. It ships with three keys and requires no additional drilling or modification to the frame. Worth considering if you have elderly family members or young children who might struggle with the keypad in poor lighting conditions.
Frequently Asked Questions
Are push-button door locks safe?
Mechanical push-button models from Lockey Digital are pick-proof and bump-proof because they contain no traditional cylinder for intruders to exploit. The 14-button keypad offers thousands of unique code combinations, and the knobs feature a slipping clutch that prevents damage if someone tries to force them. Security depends partly on choosing the correct bolt type for your frame and panel movement. For sliding installations, a hook bolt like the one found in the Lockey 2500 provides lateral holding strength that resists lifting and prying far more effectively than conventional spring latches or magnetic catches.
What are the disadvantages of keyless door locks?
Mechanical keyless systems require you to remember a code, which can be inconvenient if combinations are long or changed frequently. Models with manual throw-back, including the Lockey 2500 and 2200, need the user to re-engage the bolt after each opening. There is also no remote monitoring capability, so you cannot check from elsewhere whether the entrance was secured after someone used it. On the positive side, mechanical models avoid battery failure and electronic malfunctions entirely, making them more dependable for outdoor locations exposed to rain and temperature extremes throughout the year.
What are the best locks for patio doors?
The answer depends on whether your patio entrance slides or swings open. For sliding glass panels in timber, aluminium, or uPVC frames, the Lockey 2500 surface hook bolt is widely regarded as the strongest mechanical option available in the UK. Narrow-stile aluminium frames suit the LD950 mortice hookbolt, which fits inside the profile for a cleaner appearance. Hinged conservatory entrances benefit from the Lockey 2210 mortice deadbolt, which features a stainless steel core shaft resistant to cutting. Each model operates without batteries or wiring, making them reliable in exposed outdoor positions year-round.
Do thumb turn locks invalidate insurance?
Most UK home insurance policies require external entrances to be fitted with adequate security measures, but the specific type of mechanism is rarely prescribed beyond British Standard requirements. Thumb-turn operation on the interior side of a keypad system typically does not void the cover because the exterior remains code-protected. However, insurers do vary, so checking your policy wording is always advisable. If your provider requires keyed override capability, the Lockey LD2000 adaptor adds a cylinder backup to compatible 2000 series models, including the 2210 and 2500, giving you both keyless convenience and traditional access.
