Door Lock Repair and Replacement in Singapore

When to Repair vs. Replace Your Door Lock

247 Locksmith Singapore provides door lock repair and replacement for HDB flats, condos, and landed homes island-wide. With over 21 years of experience and a 12-person team covering all five regions, our licensed locksmiths respond within 30 minutes on average. Not every problem requires a full lock replacement - our technicians assess your lock on-site and recommend the most cost-effective solution.

Repair is usually sufficient when:

• The key turns with difficulty or gets stuck
• The lock bolt does not extend or retract fully
• The door latch does not catch properly
• Internal springs or pins are worn but the lock body is intact

Replacement is recommended when:

• The lock body is visibly cracked or corroded
• The lock has been forced open or damaged during a break-in attempt
• The lock is outdated and replacement parts are no longer available
• You want to upgrade to a higher-security lock or digital lock installation

Lock Types We Service Across Singapore

247 Locksmith Singapore’s technicians carry tools and parts for every common lock type found in Singapore homes and businesses:

HDB Main Door Locks

HDB flats and BTO units typically use mortise locks on fire-rated doors. These locks endure heavy daily use and are prone to wear over time, especially the cylinder and dead-latch mechanism. We repair and replace mortise cylinders, handles, and complete lock sets while maintaining your door’s fire rating. If you need a completely new lock fitted, see our traditional lock installation service.

Iron Gate Locks

The iron gate (or grille gate) at the entrance of many HDB flats uses a separate lock, often a rim lock or padlock. Singapore’s humid climate accelerates rust, and dirt buildup from void deck foot traffic can cause these locks to jam. We clean, lubricate, and repair gate locks, or replace them with modern alternatives that resist corrosion.

Bedroom and Bathroom Locks

Interior locks for bedrooms and bathrooms in HDB flats and condos are typically knob locks or lever handle locks with privacy functions. These can jam, especially when children accidentally lock themselves in. We provide fast unlocking and repair or replacement of interior locks.

Sliding Door Locks

Sliding door locks on balconies and patio doors use a hook-bolt mechanism that can wear out or become misaligned. We realign, repair, or replace sliding door locks to restore smooth and secure operation.

Cabinet and Letterbox Locks

Small locks on cabinets, drawers, and HDB letterboxes are often cam locks. We replace lost keys, repair jammed cam locks, and upgrade letterbox security.
