Resale HDB lock handover checklist: keys, gates and digital access

A resale-flat handover is a good time to make a clear record of who can enter your home. Start with every entrance lock and every way it can be operated, rather than treating the main-door key as the whole handover.

Coordinate any changes with the seller or agent and arrange access for the agreed handover. A complete key ring is a useful inventory, but it cannot tell you whether other copies have been made.

Make a separate entry for each lock

Walk through the flat with a short written list. For each item, record the keys or access devices received, the visible brand or model, and any difficulty operating it.

• Main door: account for its keys and check that the door closes and the lock operates without force.
• Metal gate: treat this as a separate lock. Do not assume the main-door key also operates it.
• Letterbox: check that you have the correct key and can access your own box. Our letterbox guide covers this separately.
• Other locks: include any bedroom, cupboard or storage lock that is part of the handover and matters to you.
• Digital access: list cards, fobs, PINs, fingerprints, apps and backup keys that the installed model supports.

The aim is to identify missing access and unreliable hardware before you have to organise a visit in a hurry. You do not need to choose a replacement product at this stage.

Decide what needs a new key, and what needs new hardware

Ask a locksmith to assess each existing mechanical lock rather than assuming every door needs a complete replacement set.

A compatible lock in suitable condition may have an option to change its key access; worn, damaged or unsuitable hardware may need a different solution. Our rekey-versus-replacement guide explains those options in more detail.

For the handover, the questions are practical: which old keys will stop working after the proposed job, which locks are included, and how many new keys will be supplied? Ask for a written description of the proposed work. Keep a record of the completed work and the date.

Transfer digital ownership, not just the everyday PIN

If a digital lock stays with the flat, ask the seller to demonstrate the owner or administrator access and identify the exact model. Follow that manufacturer’s handover process with the seller or authorised installer.

Changing a familiar PIN alone does not establish that all other credentials and app permissions have been addressed. Ask how previous users, cards, fingerprints and app owners are removed, and how your own access is verified afterwards.

The process varies by product. Yale’s guidance for previously owned smart locks, for example, describes situations that need the previous owner’s involvement. Do not assume every model can be transferred through the same reset sequence.

Have the manual, model details and any supplied backup key available. Confirm a working way to enter before testing changes; do not reset an unfamiliar lock while relying on it as your only access.

Check the door before choosing a replacement lock

For a fire-rated main door, ask the supplier or installer to confirm the proposed hardware’s suitability before work starts. SCDF explains how to check digital lock certification for fire-rated doors. A product’s appearance or advertised features do not establish compatibility with your door.

Keep the door closer in place. HDB’s door-care guidance says the closer on a fire-rated entrance door must not be removed. Raise a door that catches, slams or does not close correctly with the installer rather than working around it by disabling the closer.

Book one visit with a clear scope

Before arranging HDB locksmith help, gather the inventory, lock photos, model names and a list of missing keys or credentials. Tell the locksmith which doors must remain usable while the work is done.

Ask for a written description of the locks covered, whether the proposal is repair, rekeying or replacement, and what keys or setup assistance are included. Keep people, house numbers, personal details and access codes out of any photos shared for an enquiry.
