What recent reviews say

Customers consistently report same-day or next-day service with minimal wait. Staff respond at all hours, including midnight calls, and installers arrive early or on time. The team teaches users how to set up fingerprint and facial recognition on site, handles alignment issues from previous installs, and avoids hard-selling unnecessary upgrades.

Technicians deliver clean, neat workmanship that conceals old drill holes and fits locks seamlessly to door design. Interlock sends warranty terms and user guides in writing, maintains a clear invoice record, and focuses on matching the right lock model to each customer's existing setup rather than the priciest option. Multiple reviewers cite Alex or Marlene by name.

Common questions

How fast can Interlock install a smart lock?
Next-day installation is common; same-day service is available depending on availability. They also respond to emergency calls at midnight and prioritise broken lock replacements.
Will I need new drill holes if I'm replacing an old lock?
Not always. Interlock checks compatibility and can install replacement models that fit the existing shape, avoiding new drilling. They also conceal old holes from previous installs.
Do they teach you how to use the biometric features?
Yes. Installers provide on-site training for setting up fingerprints, RFID tags, facial recognition, and palm vein recognition for all household members.

Reviewers consistently report steep charges far above market rates, failed key duplicates that did not work, and shoe repair jobs that fell apart within weeks. The owner does not respond to complaints or acknowledge mistakes. One reviewer praised fast key duplication, but this was buried under 21 critical reviews citing inflated prices (belt shortening quoted at $30 versus $6-10 elsewhere), damaged shoes, defective keys, and closed hours that did not match their published schedule.

Staff at My Digital Lock earn consistent praise for patience and genuine helpfulness without pushiness. Julia, Molly, Britney, and installation technician Ah Long are named repeatedly for clear product explanations, tailored budget-conscious recommendations, and warm service from first inquiry through setup. The business stocks a wide range of digital locks from $299 up to $550, spanning door and gate models with features like dual battery backup and motion detection. Purchases flow smoothly, with staff actively helping customers match locks to their home's needs rather than upselling.

Responses come within an hour, often much faster. Staff diagnose problems efficiently and complete work in minutes. Dave and John are named repeatedly for quick turnarounds and professional skill. One reviewer was offered free phone guidance rather than a service call for a digital lock battery issue. Upfront quotes come with no hidden charges. Trust and reliability run through every report. A repeat customer called back after using the service twice.
