Reading your photo correctly is our risk, not yours.

Not a general locksmith. We do not take door, gate, car or safe work, so we carry the right parts and finish most jobs on the first visit.
Locked out of your mail at midnight? We answer round the clock, every day of the year, and urgent installation slots are available.
Our combination models need no battery, ever. Nothing to charge, nothing to fail at the wrong moment.
We send you a video of the finished, tested lock. You confirm it is right, then you pay. Nothing is charged before that.
If we confirmed a model from your photo and it does not fit, you pay nothing — including no attendance fee.
We group jobs by area each day, so you get a confirmed arrival window instead of waiting in all afternoon.
We carry every model we list, plus the cams and nuts that go with them. No ordering in, no second trip.
We verify you are the resident, owner, tenant or authorised person before opening any locked mailbox. ID is sighted only, never copied.
We are a dedicated letterbox lock specialist. Every quote is prepared by the team that carries out the work, so the written price and the final price are the same number. Our installers are trained on every model we supply and carry the full range and fittings on every visit.
Interior designers, renovation firms, developers, MCSTs, managing agents, town councils, property agents and landlords — as well as individual residents. Whatever the letterbox lock need is, it is handled end to end by the same specialist.
Handover-ready locks fitted to your schedule, one consistent model across every unit, and a single consolidated invoice.
Whole-development mailbox bank fit-out before TOP or handover, surveyed first and completed as a scheduled programme.
Block-wide replacement in one coordinated visit, with a written per-unit scope your committee can approve.
Estate-scale programmes across multiple blocks, sequenced so residents keep access to their mail throughout.
Between-tenancy lock changes so an outgoing tenant's key or code never opens the next tenant's mail.
One lock, one visit, one written price — the same service and warranty as our largest projects.
Shared mail rooms in shophouses, industrial units and small offices, fitted outside your business hours.
Whatever the need, it is handled by the same specialist from quote to completion. No subcontractors, no handover.
Send the estate name, the unit count and one photo of a representative mailbox. You get a written per-unit scope and a single consolidated quote.
Feedback from 6 customers who agreed we could share it, with the job and model shown so you can see what was actually done.
Lost my letterbox key on a Sunday. Sent a photo, got a price, and it was opened and re-keyed within two hours. Very fair rate.
Upgraded to a keyless PIN lock. Clean installation, tested everything and showed me how to reset the code. Highly recommend.
Our whole block's MCST used them for a bulk replacement. One appointment, single invoice, no fuss. Good value.
Jammed lock replaced within hours of calling. Transparent pricing with no hidden charges. Friendly and professional.
Responsive on WhatsApp and arrived on time. The battery-free lock is exactly what I wanted — nothing to charge.
Elderly mother kept losing keys, so we went with a keyless code lock. She finds it so much easier now. Thank you!
Every entry above is a real customer who agreed we could publish their feedback. A public review profile is being set up — until then, ask us for references before you book.
Nothing is charged until you have seen the finished lock working and told us you are happy.

We cover all of Singapore, 24 hours a day. Find your station below, or just send your postal sector — we will tell you the next run passing it.
Letterbox and mailbox lock replacement across every HDB town, condominium and landed estate in Singapore. If your estate is not listed, send your postal sector — it is still covered.
Landed homes and estates away from a station are covered too — MRT lines are listed simply because they are the easiest way to find your area.
Choose one lock or build a list for multiple letterboxes, then add your address. WhatsApp opens with your order ready to send.
Supply and installation starts from S$50 for a standard HDB or condo letterbox. If the mailbox is locked and the key is lost, opening adds S$25 per unit, so a typical open-and-replace job starts at S$75. Digital touch-PIN models start at S$60 and the range tops out at S$85. Urgent installation adds S$10. The final price is confirmed in writing after we review your photo.
Yes. We answer WhatsApp and phone round the clock, every day of the year, including public holidays. Late-night and early-morning lost-key openings are a regular part of what we do. Urgent installation, at any hour, carries a S$10 surcharge, stated in writing before we travel — there is no separate night rate and no emergency multiplier.
Yes. We cover every HDB town and condominium in Singapore, plus landed homes and outdoor mailboxes. We plan routes across the island each day, so your job is slotted into the next run passing your postal sector and you get a confirmed arrival window before we travel.
Yes. We open the locked mailbox and fit a replacement lock the same visit. Opening starts from S$25 per unit and we verify on site that you are the resident, owner, tenant or an authorised person before anything is opened.
After the job is done and you have confirmed it. We install the lock, send you a short video of it working, and you only pay once you are satisfied. There is no deposit, nothing to pay online and no card details taken.
Yes — most of our range. Our combination models (P2, P3, P5, P6, P8 and P9) have no battery at all, so there is nothing to charge and nothing to fail. Only the digital touch-PIN models (P4 and P7) use a replaceable battery, and those warn you before it runs low.
Most single replacements take 15 to 30 minutes once we are on site and the mailbox is accessible. Bulk jobs for a whole block are scheduled as one coordinated visit.
For your own unit's letterbox you do not normally need approval — the lock is yours to maintain. For a block-wide or common-area mailbox bank, the MCST, managing agent or town council must approve the works first, and we help prepare that request before anything is scheduled.
In most cases, yes. Send one straight-on photo of the mailbox front and we identify the cut-out, cam type and swivel direction, then confirm in writing which model fits. If we confirm a model and it does not fit on site, you pay nothing — including no attendance fee.
No call-out fee and no attendance fee. Standard visits on our daily route carry no travel charge at all. The only additional charge is S$10 for urgent installation, a special arrangement outside our planned route — and that figure is in your written quote before we travel.
Yes. We are a one-stop letterbox lock solution for interior designers, renovation firms, developers, MCSTs, managing agents, town councils, property agents and landlords, as well as individual residents. Projects get one consistent model across every unit, a written per-unit scope, work scheduled around your handover or TOP date, and a single consolidated invoice.
