Best Smart Lock for Wooden Doors: 2025 Expert Review
DR Joinery
Expert Joiner & Proprietor
Fitting a smart lock to a comprehensive UPVC or composite door is straightforward, but wooden doors present a unique challenge. Timber enters a constant cycle of expansion and contraction depending on the humidity and temperature. In York's damp winters, a wooden door can swell significantly, which plays havoc with precision electronic locking mechanisms.
Many homeowners buy the flashiest gadget they see online, only to find the motor burns out because the door 'binds' in the frame, or the lock body doesn't cover the existing mortise holes left by the old handle. As a joiner, I often get called out to fix these botched DIY attempts.
In this review, I have analysed three specific smart locks available on the UK market. I have evaluated them not just on their 'smart' features, but on how they physically integrate with timber joinery, focusing on weatherproofing, compatibility with UK multipoint systems, and build quality.

Specs vs. The Real World
The Spec: "Works on all wooden doors"
"Marketing suggests these locks fit any timber door simply by swapping the handle."
Wooden doors in older properties often have non-standard thicknesses or warped frames. If the door usually needs a firm pull to latch, a smart lock motor will struggle and likely fail.
The Spec: "DIY Installation in 15 mins"
"Just a screwdriver is needed to retrofit the lock."
This is rarely true for timber. You often need to chisel out the mortise slightly to accommodate new cables or deeper mechanisms. If you compromise the timber core/stile, you weaken the door's security.
My Top 3 Recommendations
Three options to cover different needs and budgets
AILRINNI Smart Door Lock, Fingerprint Door Lock, 12-in-1 Biometric Electronic Smart Lock
AILRINNI
For those just dipping their toe into smart home security, this AILRINNI unit offers an incredible amount of functionality for the price. Whilst I would hesitate to put a £50 lock on the main entrance of a high-value heritage property, it is an excellent choice for a garden office, internal garage door, or a side gate made of timber.
The Good
- Excellent value for money given the feature set
- Multiple entry methods prevent lockout scenarios
- Includes mechanical key override (essential for electronic failures)
The Bad
- Zinc alloy construction feels lighter than premium brass/steel fittings
- Design is quite modern; may clash with period timber doors
- Requires gateway (sold separately) for Wi-Fi remote access
Installer Tip:
When fitting this to a wooden door, ensure the strike plate is aligned with millimetre precision. If the deadbolt rubs against the wood, the batteries will drain rapidly trying to force the lock.

Ruveno
This is a serious piece of kit designed specifically for the UK market. Unlike generic imports, the Ruveno is built to work with 'lift-to-lock' multipoint mechanisms, which are standard on high-quality modern timber and composite doors. The weatherproof rating is genuine, making it suitable for exposed front doors facing the Yorkshire elements.
The Good
- Specifically designed for UK weather with waterproof front panel
- Works with standard UK Lift-to-Lock multipoint systems
- Slimline design fits well on narrow door stiles
The Bad
- Significant investment compared to budget options
- Installation likely requires professional adjustment of the mortise
- Doesn't work if your current handle doesn't lift up to lock
Installer Tip:
Timber doors in the UK often feature a 35mm or 45mm backset. Check your existing lock centre measurements carefully against the 3585 mortise spec before ordering, or be prepared to fill and re-cut the lock pocket.

Check Price on AmazonEseesmart Smart Door Lock with Handle, Fingerprint Door Lock with RFID Keypad
Eseesmart
The Eseesmart bridge the gap between budget and premium. It addresses the common headache of finding a lock that fits 'standard' UK holes. It covers a wide range of door thicknesses (40-120mm) and includes the 3585 mortise, making it a problem-solver for older doors where modern standard locks might not fit without extensive woodwork.
The Good
- Accommodates very thick doors (up to 120mm), great for heavy oak entrances
- Designed for UK weather (Waterproof & rust-proof)
- Good balance of features and price
The Bad
- App interface is functional but less polished than premium brands
- Handle rotation feel isn't as weighty as traditional ironmongery
Installer Tip:
If fitting to an older wooden door that has been painted many times, strip back the paint where the rubber gasket sits. This ensures a watertight seal and prevents moisture from getting into the electronics behind the handle.
