Moving into a new flat in Singapore: a locksmith checklist

Moving into a new place brings a long list of things to sort out, and locks can easily slip down the priority list behind furniture and utilities. It’s worth moving it back up, since securing your new home properly is easier to do before you’ve settled in than to retrofit later.

Why this matters regardless of flat type

Every kind of move raises the same underlying question: who else might have a working key or code for this door? For a new BTO flat, the answer is usually no one, since it’s handed over without any lock fitted at all. For a resale flat, a rental, or a condo, previous owners, tenants, agents, or contractors may have had keys or codes over the years, and there’s no reliable way to know how many copies exist.

This isn’t about assuming the worst of anyone who lived there before you. It’s simply that keys accumulate over a property’s history, and starting fresh with your own locks removes the guesswork entirely.

New BTO or newly built flats

New flats are typically handed over without any lock on the main door or the metal gate, so this is one of the first jobs a new owner needs to arrange, often timed around HDB key collection day. Many owners choose to have the main door lock, the gate lock, and sometimes a digital lock all fitted in the same visit, since it’s more efficient than separate appointments.

Resale flats

A resale flat almost always has existing locks, and the main decision is whether to rekey or fully replace them. Rekeying, which changes the internal pins so old keys stop working while keeping the existing lock body, is usually the more affordable option if the hardware is in decent condition. Full replacement makes more sense if the locks look worn, outdated, or if you’d rather switch to a different type entirely, like moving from a standard key lock to a digital one.

Flat type	What to check first
New BTO	No lock exists yet; arrange main door, gate, and optional digital lock
Resale flat	Decide rekey vs replace based on lock condition and age
Condo	Check if main door and any secondary locks both need attention
Rental	Confirm with landlord who arranges and pays for any lock change

Condos and landed properties

Condo units sometimes have more than one lock point to consider, particularly if there’s a separate utility or storage door, and landed properties often have gates in addition to the main house door. Walk through every entry point when you move in, not just the front door, since it’s easy to overlook a side gate or back door that also needs a fresh lock or at least a rekey.

Timing it around your move

If you’re coordinating movers, contractors, and utility appointments in the same week, it’s worth booking the locksmith visit early rather than treating it as the last item on the list. Many owners schedule it for the same day as key collection or the first day they have access to the unit, before furniture and boxes make the entrance harder to work around. Doing it early also means you’re not living in a new place with unknown keys in circulation for longer than necessary, even if it feels like a low priority next to unpacking.

Renting rather than owning

If you’re renting, check with your landlord before assuming you can change the locks yourself, and confirm who’s expected to cover the cost. This is worth raising before you move in rather than after, since it’s an easier conversation to have at the start of a tenancy than partway through.

Getting it all done efficiently

Bundling everything into one visit, main door, gate, and any digital lock addition, generally costs less than separate callouts and gets your new place secured faster.
