If you’re after a no‑nonsense mechanical door lock that gets the basics dead right, the Godrej Khatakhat Ultra XL Door Lock 1CK is one you’ll want on your shortlist — especially for homes and small commercial spaces where you don’t need fancy electronics but do want solid security. This is old‑school locking tech done properly, with a one‑side key system and inside knob action that’s simple and predictable in everyday use.

Forget bells and whistles — with its 14‑pin Ultra XL+ cylinder, this lock throws roughly 10 crore possible key combinations at would‑be key duplicators, and that matters a lot when you’re securing a front door that actually gets used. The body and bolt setup are built to resist force and weather, and the finish stands up to corrosion so it doesn’t turn into a crusty door anchor after a couple of monsoons.

Key Features:

• Ultra XL+ 14‑Pin Cylinder - Generates tons of key combinations, making casual key copying a real headache for anyone trying it.
• One‑Side Key Mechanism - Only needs a key from the outside and a knob inside, so you can lock up fast when you dash out.
• Steel Lock Body - Thick, stamped steel stands up to kicks, shoulder checks, and everyday bumps — not delicate stuff you’ve got to baby.
• Safety/Privacy Knob - Engage it from inside and nobody gets in from outside, even with the correct key — nice when you’ve got guests or kids around.
• Wide Compatibility - Fits inward‑opening wooden and plywood doors between roughly 25–60 mm thickness — good for most Indian home setups.

Applications

This is a mechanical entry door lock that’s ideal for main entrance doors, side doors, servant quarter doors, or store room doors where you want reliable key access from outside and simple knob control inside. In practice, it’s especially suited to inward‑opening wooden or plywood doors in homes or offices — you mount it, crank it, and forget it until you need it.

Why Choose This Model

Here’s the thing — you don’t need a smart lock with apps and batteries for every doorway. Sometimes what matters most is having a lock that’s easy to service, easy to operate, and not going to quit on you when the kid drops their lunchbox into a monsoon puddle. The Godrej Khatakhat Ultra XL Door Lock 1CK gives you exactly that: straightforward mechanical operation with plenty of security built into the pin cylinder and solid metalwork that keeps working year after year.

Technical Specifications Explained

• Lock Type - A one‑side key rim lock, meaning you use a key on the outside and a knob inside — easy and intuitive for everyday use.
• Backset (60 mm) - This is the distance from the door edge to the keyhole centre, and 60 mm is the standard you’ll see on most residential wood doors — no weird fit issues.
• Door Thickness Range - Works on doors from around 25 to 60 mm thick, so whether you’ve got a thin internal door or a beefier entrance, it’ll clamp right in.
• Number of Keys - Typically ships with four numbered/grip‑buttoned keys so everyone in the house has their own copy — practical.
• Finish - Electroplated and corrosion‑resistant finish means it won’t pit or flake off for a good long while, even in humid conditions.

Who Should Buy This

If you’re looking for a solid mechanical door lock that won’t leave you sitting in the rain because a battery died, this is a no‑nonsense pick for homeowners, apartment dwellers, landlords, and small office owners. It’s not flash — it’s workhorse stuff that gets the job done without drama.

And if you care about keeping cut‑rate copies of your keys from working, if you want a lock body that stands up to everyday abuse, and if you prefer simplicity over gadgetry, you’ll appreciate what this model brings to the table.
