Smart Lock Sourcing in China Without Guessing the Hidden Parts
We help buyers compare smart locks against the same door, mortise, access methods, software expectations and approved sample version.
Direct answer
How do you source smart locks from China?
Start with the actual door material, thickness, opening direction, backset, existing cutout, mortise dimensions and required cylinder or override. Then define access methods, user capacity, power, emergency entry, language, app or platform needs, finish, accessories, packaging, quantity and destination market. Ask suitable suppliers to confirm compatibility rather than selecting from panel photographs. Test a sample on a representative door and record hardware, firmware, app and accessory versions. Before production, freeze that baseline and identify what evidence or testing the buyer requires for the target market.
Compatibility first
The door and mortise decide whether the lock can be installed
A suitable front panel does not prove that the spindle, screw positions, latch direction or mortise will fit. Send a dimensioned door drawing or clear measurements from both sides and the edge.
Door
Material, thickness and handing
Cutout
Existing holes and edge dimensions
Mortise
Case size, backset, centers and faceplate
Interface
Spindle, cylinder, cable and fasteners
What sits behind the quotation
Compare the lock as four connected layers
Reader, keypad, fingerprint module, board, motor and power arrangement.
Local programming, app, gateway, user roles, logs and update method.
Cards, keys, manuals, branding, packaging, spare parts and support scope.
The same model name may hide a different mortise, board, fingerprint module or firmware. Ask the supplier to identify substitutions before production.
Scenario-based sample review
Test the actions a real user and installer will perform
Install
Check drilling references, handed setup, cables, fasteners and alignment.
Enroll
Add and remove users, cards, fingerprints or codes as specified.
Operate
Try normal entry, locking, low-power warning and emergency access.
Recover
Review reset authority, lost-phone handling, override and support steps.
Record the sample model, mortise, board or firmware information, app version and included accessories. A later software update may change screens or functions, so confirm which behavior controls the order.
Supplier and evidence checks
Confirm who controls the product after assembly
A smart lock supplier may make panels, purchase mortises and electronic modules, license an app, or only complete assembly. Review which party can correct mechanical problems, revise firmware, maintain the app and supply matching spare parts.
Available certificates or reports should be checked for holder, manufacturer, model, standard, date and limitations. Wireless, battery, cybersecurity, fire-door or accessibility requirements vary by product and market. ALF Supply organizes supplier information but does not make legal compliance decisions.
Lock compatibility starts with the door, not the product photo
For smart locks, the buyer should establish the physical door conditions before comparing models. Record door thickness, mortise dimensions, backset, opening direction and the existing hardware. Then define the user journey—fingerprint, keypad, card, app, key or other access—and the power and emergency-access requirements.
Smart-lock reference pack
- Door and mortise measurements
- Required access methods and user roles
- Power, battery and emergency-access requirements
- App, connectivity or firmware expectations
A supplier can confirm a model only against the information available. Compatibility should be checked against the actual installation conditions.
Prepare your inquiry
Send door measurements and the required user journey
Include photographs, door thickness, handing, cutout or mortise drawing, access methods, app needs, quantity, finish, destination and delivery date. Mention the current lock if this is a replacement.
