Digital / Smart Lock Installation on Existing Door — Causes, Fixes & Cost in KL
You bought a Samsung, Yale, Kaadas or similar smart lock and need it installed on your current door properly.
Estimated professional fix: RM 250–RM 550+ per door
A smart lock is only as secure as its installation. The lock itself — Samsung, Yale, Kaadas or similar — is fine off the shelf; what decides whether it protects the door is the prep work: the right mortise cut for the lock body, the correct thumb-turn alignment, a battery pack that is reachable, and access codes that are actually tested in every mode (fingerprint, card, code, app, and the emergency key). On metal or fire-rated doors the work is harder because the mortise has to be cut into steel, and a bad fit on a short-let or rental door means a locked-out guest and a JMB or tenant dispute. Most of the "smart lock doesn't work" calls we get trace back to installation shortcuts, not the hardware.
Common causes
Professional solutions
Safe DIY checks first
- 1Measure the door thickness (35–55 mm typical) and the bevel edge before buying or scheduling — the spec sheet must match the door
- 2Check the existing mortise: if the old mechanical lock body size differs from the smart lock, the door will need a new cut
- 3For metal or fire-rated doors, confirm the lock is rated for that material — standard wood-door bodies will not cut or hold correctly
- 4If the door is a short-let or Airbnb, decide which access codes and self-check-in features you need before installation day
When to call a pro
What affects the cost
Installation on a standard timber or composite door runs RM250–RM450 per door, covering the mortise cut where needed, body fitting, wiring of the battery pack, app pairing, and full access-code testing. Metal or fire-rated doors take longer and sit at RM450–RM550+. We complete pairing with your phone, enrol fingerprints and user codes, and hand over the emergency key and manual. Typical time: 45–90 minutes standard, 90–150 minutes metal doors.
