Door lock prices in Bangladesh range from about ৳250 for a basic latch to ৳45,000 or more for a feature-rich smart lock, with installation often charged separately. The final price depends on lock type, door material and thickness, brand, security grade, and whether fitting requires drilling or changes to the door.
Amounts below are indicative retail estimates in Bangladeshi taka (BDT); USD conversions use approximately ৳120 per US$1 and are rounded. Local shop prices, imported stock, and exchange rates can change the quote.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Basic latch or barrel bolt | ৳250 (US$2) | ৳700 (US$6) | ৳1,500 (US$13) | Simple interior or secondary security fitting |
| Standard cylindrical or mortise lock | ৳800 (US$7) | ৳2,500 (US$21) | ৳6,000 (US$50) | Common keyed entry lock, usually excluding fitting |
| Heavy-duty or branded lock | ৳3,000 (US$25) | ৳7,500 (US$63) | ৳15,000 (US$125) | Higher-grade body, finish, or cylinder |
| Digital or smart lock | ৳8,000 (US$67) | ৳22,000 (US$183) | ৳45,000 (US$375) | Price varies by access methods and door compatibility |
| Lock installation | ৳500 (US$4) | ৳1,200 (US$10) | ৳3,000 (US$25) | Basic replacement through more involved fitting |
What a typical Bangladesh door lock costs
For a standard apartment or house entrance, a conventional keyed lock commonly costs ৳1,200-৳4,000 (US$10-US$33) for the product. With ordinary installation, a buyer may spend about ৳1,800-৳5,500 (US$15-US$46). A more secure branded mortise set can bring the installed total to ৳4,000-৳10,000 (US$33-US$83), depending on the door and hardware included.
Prices at the lowest end usually cover a basic mechanism rather than a complete handle-and-lock set. Product listings may also exclude screws, strike plates, extra keys, or fitting. Smart locks cost substantially more: a typical installed unit is about ৳10,000-৳28,000 (US$83-US$233), while premium models or difficult installations can exceed ৳50,000 (US$417).
Assumptions: Typical urban retail pricing, standard single-door installation, and no major repair to the door or frame. USD values are approximate conversions.
For a routine entry-door replacement, budgeting ৳2,000-৳6,000 (US$17-US$50) covers many standard locks and straightforward fitting.
How cylinder, mortise, and smart-lock prices compare
Lock type is a major price driver because each design uses different hardware and may require different preparation. A simple latch suits an interior door or as an additional bolt, but it is not a substitute for a properly fitted main entrance lock. Cylindrical locks are often easier to replace, while mortise sets fit into a pocket cut into the door edge and may include a handle.
| Lock type | Product price | Typical fitting | Common use | Budget note |
|---|---|---|---|---|
| Barrel bolt or latch | ৳250-৳1,500 (US$2-US$13) | ৳300-৳800 (US$3-US$7) | Interior door or added bolt | Lowest cost, limited as a primary lock |
| Cylindrical keyed lock | ৳800-৳3,500 (US$7-US$29) | ৳500-৳1,500 (US$4-US$13) | Common residential doors | Check backset and door thickness |
| Mortise lock set | ৳1,800-৳8,000 (US$15-US$67) | ৳800-৳2,500 (US$7-US$21) | Wood or metal entry doors | May require a correctly sized pocket |
| Digital keypad or fingerprint lock | ৳8,000-৳45,000 (US$67-US$375) | ৳1,500-৳4,000 (US$13-US$33) | Homes, offices, short-term rentals | Confirm power, thickness, and backup access |
Some sellers use “smart lock” for a keypad-only model, while others mean a connected device with app access, fingerprint scanning, or remote control. A higher feature count does not automatically mean a better fit. Check whether the model includes a mechanical key, emergency power option, and local service support before comparing prices.
Compare the complete set and fitting cost, not just the lock body’s displayed price.
Which parts of a Bangladesh lock quote add up
A quote may combine the lock, handles or escutcheon plates, installation labor, delivery, and any door preparation. For replacement, an installer may reuse existing holes and strike plates; for a new lock type, cutting or drilling can increase labor. Ask whether the quote includes removal of the old mechanism and adjustment of the latch alignment.
| Quote item | Typical price | What changes the charge | Budget check |
|---|---|---|---|
| Lock and cylinder | ৳800-৳8,000 (US$7-US$67) | Type, material, brand, included keys | Confirm whether handles and strike plate are included |
| Installation labor | ৳500-৳2,500 (US$4-US$21) | Replacement versus new cutout | Ask for a separate fitting charge |
| Door drilling or mortise work | ৳300-৳1,500 (US$3-US$13) | Door material and required modifications | Clarify if this is included in labor |
| Old lock removal and disposal | ৳100-৳500 (US$1-US$4) | Rust, damaged screws, or seized cylinder | May be bundled with replacement |
| Delivery or service visit | ৳150-৳800 (US$1-US$7) | Distance, urgency, and provider | Check for a minimum visit fee |
For labor estimates, the basic calculation is time multiplied by the installer’s hourly rate, though many local providers quote a flat amount per door. A straightforward replacement may take 30-60 minutes; drilling, alignment, or a smart-lock setup can take 1-3 hours.
Get an itemized quote so added drilling, travel, or removal does not appear as an unexpected charge.
Door thickness, material, and security grade change the price
Door measurements matter because a lock must match the thickness, edge preparation, and backset—the distance from the door edge to the lock center. Many residential doors fall around 35-45 mm thick, but metal security doors and older doors can differ. A lock that does not fit may require a different cylinder, extension, or additional work.
Door material also affects fitting. A pre-cut wooden door may accept a replacement mortise set with modest labor. A steel door can need compatible hardware and careful drilling, while a damaged wooden frame may need repair before the strike plate can hold securely. These conditions can add about ৳500-৳3,000 (US$4-US$25) to labor and preparation.
Security grade affects price through cylinder construction, deadbolt design, body strength, and resistance to forced entry or picking. A basic lock can cost ৳800-৳2,000 (US$7-US$17), while a heavier branded set may run ৳4,000-৳15,000 (US$33-US$125). A lock with an anti-drill cylinder or reinforced deadbolt typically costs more than a light-duty interior mechanism.
Smart-lock compatibility has additional thresholds. Some models fit door thicknesses of roughly 35-60 mm, but the exact supported range varies. A door thinner or thicker than the stated limit may need a special kit or may not accept the model at all. For a door with a 60 mm or greater thickness, verify product specifications before ordering.
Measure the door and existing lock before buying; a mismatch can erase the savings from a low product price.
Dhaka and other city quotes can differ
Bangladesh does not have one fixed national retail price. In Dhaka and Chattogram, buyers may find wider selection and more imported or premium models, but service rates and delivery charges can be higher. A reasonable planning allowance is roughly 5%-15% above a smaller-town quote for comparable branded products and service, although promotions and stock can reverse that difference.
In smaller cities and rural areas, common mechanical locks may be available at similar or lower prices, but a specific smart-lock model may cost 10%-25% more if it must be ordered from a major city. Travel for installation can add ৳300-৳1,500 (US$3-US$13), especially when the provider charges for distance or a separate service visit.
Price comparisons should use the same lock model, included hardware, warranty terms, and installation scope. Two sellers may quote the same product at different totals because one includes fitting and the other does not. For imported products, confirm whether local replacement parts and warranty service are available.
Assumptions: Regional percentages are planning estimates rather than fixed tariffs; dealer, stock, and transport conditions vary.
Compare at least two local quotes using the same model number and a clear list of included services.
Three realistic installed lock budgets for common doors
A low-cost interior replacement is a basic latch or cylindrical lock on a prepared wooden door. A typical estimate is ৳700-৳1,800 (US$6-US$15), including a product around ৳400-৳1,000 and 30-45 minutes of fitting. This option is appropriate for a low-security interior door, not necessarily for the main entrance.
A standard apartment entrance upgrade might use a midrange mortise set priced at ৳2,500-৳5,500 (US$21-US$46), plus ৳800-৳1,800 (US$7-US$15) for fitting and alignment. A likely total is ৳3,300-৳7,300 (US$28-US$61). The estimate assumes a compatible door and no frame repairs.
A smart-lock installation on a compatible door may include a keypad or fingerprint unit at ৳12,000-৳25,000 (US$100-US$208), plus ৳1,500-৳3,500 (US$13-US$29) for installation and setup. The total is often ৳13,500-৳28,500 (US$113-US$238). Extra charges are possible if the door needs modification or Wi-Fi accessories are sold separately.
These examples show why a complete installed quote can be much higher than the product’s shelf price.
When repair costs less than replacing the lock
A sticking latch, loose handle, or misaligned strike plate may need adjustment rather than a complete new lock. A basic adjustment or tightening service may cost ৳300-৳1,000 (US$3-US$8); replacing a small spring, screw, or cylinder may bring the total to roughly ৳500-৳2,000 (US$4-US$17). Costs depend on parts availability and whether a call-out charge applies.
Repair is less attractive when the lock body is cracked, the key repeatedly jams, the cylinder is badly worn, or the lock no longer secures the door reliably. If a replacement cylinder alone costs close to half the price of a complete new set, compare both options. A locksmith may also recommend replacement after lost keys or a break-in, when restoring access control is more important than the cheapest immediate fix.
For a smart lock, check battery condition, firmware or keypad issues, and the availability of a manual key before replacing the unit. A battery replacement may cost only ৳200-৳800 (US$2-US$7), while a control-board or motor repair can be much more and may not be worthwhile if the product has no local parts support.
Pay for diagnosis before replacing a lock when the problem may be limited to alignment, batteries, or a replaceable cylinder.
How to lower the lock bill without weakening the fit
Keep the existing lock type and dimensions when the door is sound. Reusing the same cutout can avoid extra drilling and reduce the chance of damaging a finished door. Take the old lock or clear photos of its faceplate, cylinder, handle, and door edge when asking a shop to match a replacement.
Choose features based on actual use. A quality keyed mortise lock may be a better-value entrance upgrade than a smart lock if remote access or fingerprint entry is unnecessary. For digital models, compare warranty, emergency entry, and included accessories; paying extra for app features that will not be used adds cost without improving the basic fit.
Request a written breakdown for product, installation, drilling, delivery, and removal. Compare the same model from two or three sellers, and ask whether fitting is cheaper when purchased with the lock. If several doors need replacement, bundling may reduce the per-door visit charge, but confirm each door’s measurements before ordering multiple units.
Schedule non-urgent work during ordinary business hours, since urgent evening visits may add a call-out fee. Avoid buying solely on the lowest online price until shipping, return conditions, and warranty support are clear. A lock that cannot be fitted or serviced locally can create a larger expense later.
The most dependable savings come from matching the lock to the existing door and comparing complete installed prices.
