Ketch arrives quickly and solves lockouts and replacements with care.

The business handles residential door locks, RFID drawer repairs, digital lock conversions, and key management. They recommend quality components (stainless-steel sets, Nelon hardware) and carry authorization from Yale, Samsung, Kaadas, Philips, and Igloohome. Custom work, post-installation cleanup, and honest guidance on security upgrades are hallmarks of repeat business.

Vincent and the team consistently arrive within 15 minutes to an hour and handle bedroom lockouts, stuck doors, and lock replacements with polished professionalism. Reviewers praise transparent quotes, no surprise charges, friendly communication via WhatsApp, and willingness to serve emergency calls at midnight-qualities rare enough in the locksmith trade that several reviewers mention trusting the business with sensitive security situations. Residential work dominates the visible reviews: bedroom doors, BTOs, and home lock changes. The business claims 30+ years operating across Singapore, and their website lists high-security locks and master key systems alongside lockout services. Every recent review is five stars except one four-star, which still praises the speed and professionalism.
