Key Cutting & Duplication in Singapore
A guide to choosing a key cutting and duplication shop in Singapore, with 76 providers compared on accuracy, turnaround, and blank selection.
Key cutting sounds simple until a freshly cut spare jams in the lock or won't turn a deadbolt smoothly. This category covers shops and locksmiths across Singapore who cut and duplicate keys for HDB and condo doors, gates, padlocks, mailboxes, and cabinets, along with transponder and remote key duplication for cars. We've listed 76 businesses that offer this service, ranging from void deck key stalls to full locksmith outfits that also handle lock repairs and installation.
What the service actually involves
A technician reads the grooves or pins of your original key and cuts a blank to match, either by tracing the original on a manual or semi-automatic machine, or by clamping it into a code-cutting machine that follows the key's factory specifications. For car keys and some digital locks, duplication also means cloning a chip or programming a remote, which needs different equipment and usually a longer wait.
What to check before you hand over your key
- Whether they stock the right blank for your lock brand, especially for European or high-security cylinders that need imported blanks
- Whether they test the cut key in your lock on the spot, not just hand it over uncut-tested
- Turnaround time, since transponder keys and some restricted keyways may need to be sent out or ordered in
- Whether they can cut from a code (useful if you've lost all copies) or only trace from an existing key

Common questions about key cutting & duplication
- How much does key duplication cost in Singapore?
- A basic house key copy is usually a few dollars, often between S$2 and S$8 depending on the blank. Higher-security or restricted keyways cost more, sometimes S$15 to S$30 or higher, because the blanks are pricier and less common. Car transponder keys and remotes cost significantly more, often S$50 to S$150 or more, since they involve chip programming rather than just cutting metal.
- How long does it take to cut or duplicate a key?
- Standard house, padlock, or cabinet keys are usually cut on the spot in a few minutes. Restricted or patented keyways may need the shop to order the blank in, which can take a few days. Transponder key duplication or remote programming for cars can take from 30 minutes to a few hours, or longer if the part needs to be sourced first.
- How do I know if a duplicated key is good quality?
- A well-cut key should slide in without resistance and turn the lock smoothly on the first try, not need wiggling or repeated attempts. Ask the shop to test it in your lock before you leave. If it sticks, catches, or only works after some force, the cut is off and should be redone or refunded rather than accepted as normal.
- Can any shop cut a key with a 'do not duplicate' stamp or a restricted keyway?
- Not always. Restricted keyways (common in some condo and commercial systems) are tied to a specific dealer or manufacturer and legally require proof of authorization, like a card or code tied to your unit. A shop without that access simply can't cut it, so check this before assuming any nearby stall can help.
