The buyer measured the door wrong and now the lock will not fit.
A lock is bought for a door and a fear. The door has a thickness, a fitted cutout and a side it opens on. The fear is a break-in, a lost key, a tenant who copied one, or a child locked in a bathroom. The page has to deal with both.
A 90-minute audit call and a written, scored report. Turnaround, reporting and term are agreed in writing after the audit.
In one paragraph
Locks are door locks, padlocks, cabinet locks and digital locks, bought for a particular door and a particular worry about security. GullySales writes pages that ask for the door thickness and the cutout before the buyer pays, show how the lock is fitted, and explain finish, lever count and key type in the words a homeowner uses.
A lock that does not fit the door is the commonest return. The second commonest is a buyer who thought they were buying security and bought decoration.

Who it is for
This is written for you if you sell locks online.
- Makers and brands of mortise locks, cylindrical locks and rim locks
- Sellers of padlocks, cabinet locks and locker locks
- Digital and smart lock importers who need the fitting and power questions answered
- Dealers who supply builders, carpenters and housing societies in quantity
Not for
It is not the right fit if.
- Sellers of locks with no fitting information or documentation. The buyer's first question is whether it fits.
- A business that wants to promise that a lock is 'unbreakable' or 'burglar-proof'. We will not write that, and no honest lock seller should.
How buyers choose
What decides the sale of locks.
Door thickness, cutout and handing
A mortise lock needs a mortise cut into the door and a lock case of the right size. The buyer asks the door thickness, whether it is wood or metal, and whether it opens left or right.
Lever count, key type and cylinder
A padlock buyer compares shackle thickness and body material. A door lock buyer looks at the number of levers, whether the key is dimple or pin, and if there is a master key option for a building.
Finish and match
A lock is chosen to match the handles: brass, antique, satin steel, black. The buyer looks for a photograph on a door like theirs, not on a white background.
Digital locks and the questions about power
A digital lock buyer asks which batteries it takes, what happens when they die, whether a key backs it up, and who installs it.
Where sales are lost
What usually goes wrong when you sell locks online.
In the words sellers use on the first call.
“Customers send the lock back because it does not fit the door”
Door thickness and cutout were not on the page. The right line above the buy button would have prevented a return and a bad review.
“Buyers ask whether the lock is strong and we cannot say”
Without lever count, shackle thickness and material on the page, a strong lock looks the same as a weak one. Specific numbers answer the worry.
“Our digital lock gets a flood of installation calls”
Buyers are not sure who fits it, whether the door suits and what happens in a power cut. A short fitting guide and an installer list cut those calls.
“Builders and societies want sets with a master key and we only sell single locks”
An apartment project wants matching locks on fifty doors with one master key. The enquiry needs a form and a person who understands what is being asked.
The scope
The work we would propose for locks.
Measured on purchases and, for trade buyers, qualified enquiries, quotation requests and repeat orders. Anything here that needs a platform or tool we have not used with you is confirmed in the audit before it goes in the scope.
- Fit checker on every lock pageDoor thickness range, cutout dimensions, backset, handing and door material in a fixed table, with a drawing beside it. The buyer checks against their own door before paying.
- Security detail pagesPlain notes on levers, shackle thickness, cylinder type and body material, and what each does. No claims of unbreakable locks.
- Project and society enquiryA request form for builders and housing societies that takes door count, master key needs and finish, and goes to the person who quotes.
- Video and short-form contentA close view of the lock being fitted and used on a real door. Buyers watch it to judge the build and the finish.
Fitting guides and installer information
A short video and page for installing each type, and a list of installers or a fitting enquiry where you offer one. We confirm with you what service is actually available.
What we do
What you get for locks.
Each deliverable and what it is there to change.
A door measurement guide
A one-page guide with a drawing on how to measure thickness, backset and handing. It stops the wrong-size order.
A specification table for each lock
Levers, material, finish, key type and cutout in one table. It lets a careful buyer compare without a call.
Fitting videos for the main types
Short films of a mortise lock, a digital lock and a padlock in place. They reduce the installation calls.
A project quotation form
A request page for builders and societies with master key and quantity fields. It sorts the project buyers from the single-lock ones.
How the result is measured
- Purchases
- Conversion rate
- Return rate
- Quotation requests
- Orders won
- Fit-related returns
Recorded as a baseline before work starts, so every later report has an honest comparison.
How it works
From your first message to the first report.
No open-ended retainer. Every step gives you something in writing.
First
Free audit call
90 minutes with whoever handles your enquiries: how they arrive, how fast they are answered, where they are lost.
After the call
Written, scored report
Six areas scored, fixes ranked by return and cost. If you want our help, the scope, the fee and the reporting come with it, in writing.
Before work starts
Baseline recorded
Enquiries by source, reply time, conversion and cost per order, written down so every later report has an honest comparison.
After the baseline
The first fix goes live
Usually the cheapest one on the report: reply time, a follow-up sequence or the marketing-to-sales handover.
As agreed
Report against the baseline
What moved, what did not, and what changes next, in plain words. How often you get it is set in writing before work starts.
At renewal
Renew on the numbers
The term ends and you decide whether to continue from the results. The length is agreed in writing before anything starts.
What we need from you
What to have ready before the audit call.
None of it has to be tidy. We read what you have.
- Product list with door thickness range, cutout and backset for each lock
- Fitting instructions and manuals from the maker
- Return and complaint reasons, especially fit-related
- Housing projects and builders you have supplied, and how many doors each had
- Installers you work with, if any
Selling in India and abroad
Selling locks beyond your own market.
Where you sell decides sizes, units, seasons and returns. We work from Bengaluru and have no overseas office, so for a new country we start from your own sales and the platforms you already use.
Door sizes and lock types differ by country
Doors and locks follow different standards elsewhere, and a mortise case made for Indian doors may not suit them. Check the dimensions against the target market before listing.
Digital locks and local rules
Radio and electrical rules for smart products differ by country. What is allowed for sale abroad is for your adviser and the importer to confirm.
