All 13 reviews are five-star, citing fast response times, knowledgeable staff (particularly Doris), and quality hardware. Customers praise the organized inventory and straightforward dealing without pressure to buy extras.
Yew Digital Lock wins over customers at the sales stage with clear pricing and courteous staff, but the relationship collapses once products are installed. Locks consistently malfunction within months to two years, yet the company's after-sales team ignores calls, ghosts customers for weeks, and delays warranty repairs until coverage expires.
Customers report dead fingerprint sensors, gate locks that refuse to open, and broken remote controls within the first year. When customers reach anyone, they face redirects between multiple staff members with no resolution, instructions to pay for repairs on warranted items, or vague promises of follow-up that never arrive. Several reviewers explicitly warn others not to buy.
Recent shift: Negative trend accelerating: all one-star reviews from the past 3 months detail complete after-sales collapse (unreachable staff, warranty delays, lock malfunctions). The single five-star review from a month ago (praising Darren) stands as an outlier amid a wall of escalating complaints about the same core issues-ghosting customers, missed appointments, and faulty products kept in service under warranty.

Reviewers consistently report arrival within 30 minutes, often from Woodlands or North Singapore areas, with lock issues resolved in under five minutes by Chris. The repeated strength is speed paired with politeness, along with clear pricing stated before work begins and no damage to locks even on old or complex mechanisms. Service spans residential lockouts, lock replacement, file cabinet unlocking, and door lock repairs. Chris handles jobs at midnight with the same efficiency as daytime calls. Customers mention specific costs like $120 for unlock plus replacement and $250 for a main door lock set with installation, though one reviewer noted pricing slightly higher than expected elsewhere.

Service quality swings sharply. One recent customer regained entry in 40 minutes at 11:30 pm with the lock untouched. An older job saw a metal frame plate fall off within a month, with the technician declining responsibility.
