Compatibility before confirmation
The lock can be good—and still be wrong for your entrance.
A model that looks suitable online may fail because of one measurement. We review the actual setup before narrowing your options.
Old holes and available lock areaThe new lock must cover or work around the existing cut-outs safely.
Door-and-gate spacingTight clearance can cause the gate lock, door lock or handles to interfere.

Common questions
Before choosing a digital lock.
How much does a digital lock cost in Singapore?
Selected digital locks currently start from Starting From $499 with standard installation, subject to compatibility. Final pricing depends on the setup, selected model, required features and any non-standard installation work. The full price is confirmed before booking.
How do I know whether a lock fits my door or gate?
Send clear photos of the front, back and existing lock area. For a door-and-gate setup, include both entrances closed together. We may request measurements where the spacing or existing holes are tight.
Should I choose fingerprint or face recognition?
Choose around the main users and daily routine. Fingerprint is already fast and practical for many households. Face recognition is useful when hands-free entry removes a frequent inconvenience or when some users have difficulty with fingerprint recognition.
Do I need Wi-Fi on my digital lock?
Not always. Wi-Fi is worth paying for when remote access, notifications or temporary access solves a real need. A simpler offline model can be better value for households that only want reliable keyless entry.
What happens if the battery becomes flat?
Most locks provide low-battery warnings and an external emergency-power method. Some also include a mechanical key. The exact recovery method varies by model and is covered during the handover.
What warranty and after-sales support are included?
Coverage varies by model and brand. Interlock explains the applicable lock warranty, workmanship coverage and relevant exclusions before confirmation, with local support available after installation.
