# Lost my keys in Singapore: what to check first, what it costs, who to call Source: https://honestfix.cf-migrate-pulse-web.workers.dev/guides/lost-my-keys · checked 15 Sep 2026 the Honestfix team · checked 15 Sep 2026 Lost my keys means you have no working key to your home at all, not a lock that has jammed on a key you are holding. That distinction matters, because a lost key can mean someone else now has a way in, which a jammed lock never does. ## What to check first Retrace your steps before you call anyone. The most likely cause is a key misplaced somewhere ordinary: another bag, a different jacket, a car, or a desk at work. Retracing the last few places you had the keys finds most of these before you need to call anyone. Then check who else holds a spare. The third cause is that the spare you were counting on is also missing, misplaced with a family member, or was never cut in the first place. Confirm who holds a spare before you assume you are fully locked out — a phone call to a family member can save you a callout fee entirely. While you check, think honestly about where the keys were last seen. That answer decides everything that follows: whether this is a five-minute re-entry, or a job that needs the lock changed as well. ## The likely causes, in order **Misplaced somewhere ordinary (most common).** The most likely cause is a key misplaced somewhere ordinary: another bag, a different jacket, a car, or a desk at work. Safe check: physically retrace the last two or three places you had your bag or pockets before treating it as lost for good. **Lost outside the home, in public (second most common).** The second cause is a key lost outside the home, in a public place or on transport, where you cannot retrace every step. This is the case that turns a lost-key problem into a security question, because you cannot rule out a stranger finding it. Safe check: think about whether anything on the same keyring or in the same bag identified your address. **No usable spare (third most common).** The third cause is that the spare you were counting on is also missing, misplaced with a family member, or was never cut in the first place. Safe check: call whoever you believe holds a spare before assuming you need a locksmith at all. ## When to call, and who Call a locksmith once you have confirmed there is no accessible spare. Tell them clearly whether the loss was inside the home (low risk, simple re-entry) or outside it in public (higher risk, likely needs a rekey), because that changes what they should quote you for. Stop and rekey, not just re-enter, if the lost key could be traced back to your address — for example if it was on a ring with mail, an access card, or ID. The Singapore Police Force lists housebreaking and dishonest misappropriation among its published property-crime advisory categories, which is the exact risk a traceable lost key creates. Getting back in and doing nothing else leaves that risk open. ## What it costs Ask for a firm price for both the entry and, if needed, the rekey. Ask for the entry price and the rekey price as two separate figures, quoted before anyone travels to you. A locksmith who only quotes "from" a number for the combined job is leaving room to raise it once they are at your door and you have little choice. Ask, too, whether the quote includes a new set of cut keys and how many, since a rekey with only one working key afterwards is not the full job most households need. ## Who to call, and how to judge them Lockout and lock-change work is not licensed work in Singapore, so there is no public register to check a locksmith against. Judge one on a firm quoted price, a real business you can verify, and a willingness to confirm the address is yours before opening anything. An ACRA registration confirms the business exists, nothing more. A locksmith should ask where and how the keys were lost before quoting, because that answer decides whether the job is a simple re-entry or a full rekey. All fire-rated doors at the entrance of HDB flats are installed with a door closer, a self-closing safety device that must not be removed during either job. ## Frequently asked questions **How is a lost key different from being locked out?** Lost my keys means you have no working key to your home at all, not a lock that has jammed on a key you are holding. That distinction matters, because a lost key can mean someone else now has a way in, which a jammed lock never does. **Do I need to change my lock if I lost my keys outside the home?** Stop and rekey, not just re-enter, if the lost key could be traced back to your address — for example if it was on a ring with mail, an access card, or ID. The Singapore Police Force lists housebreaking and dishonest misappropriation among its published property-crime advisory categories, which is the exact risk a traceable lost key creates. **What should I tell the locksmith when I call?** A locksmith should ask where and how the keys were lost before quoting, because that answer decides whether the job is a simple re-entry or a full rekey. ## Sources - [Singapore Police Force, Advisories](https://www.police.gov.sg/Advisories/Crime) (fetched 15 Sep 2026) - [HDB, "Fixing Gate and Door Issues in HDB Flats" home care guide](https://www.hdb.gov.sg/managing-my-home/renovation-and-maintenance/home-maintenance/home-care-guide/gate-and-door) (fetched 15 Sep 2026) - [gov.sg, Singapore Government homepage](https://www.gov.sg) (fetched 15 Sep 2026) [Compare locksmiths providers](/locksmiths) and get a firm price for both the entry and any rekey before anyone travels to you. ## Related - [Locksmiths in Singapore — compare providers](/locksmiths) — Locksmiths - [Locked out of your home in Singapore: what to do first, what it costs, who to call](/guides/locked-out-at-2am) — Guide: Most lockouts are a jammed bolt, a broken key or a dead digital lock battery, not a broken door. - [Key stuck in lock in Singapore: what to check first, what it costs, who to call](/guides/key-stuck-in-lock) — Guide: Stop turning and wiggling the key before it snaps; that turns a callout into a lock replacement. - [Aircon compressor faulty in Singapore: what to check first, what it costs, who to call](/guides/aircon-compressor-faulty) — Guide: A silent outdoor unit while the indoor fan still blows usually means the compressor. - [Aircon gas leak in Singapore: what to check first, what it costs, who to call](/guides/aircon-gas-leak) — Guide: Cooling that fades over weeks, not a sudden stop, usually means a gas leak. - [Aircon leaking water in Singapore: what to check first, what it costs, who to call](/guides/aircon-leaking-water) — Guide: A blocked drain pipe, not a broken unit, causes most aircon water leaks — a chemical wash usually clears it.
