Godrej Astro EXS+ 1CK: Ultimate Door Security Lock

Product Overview

Indian homes, contractor sites, and DIY projects demand locks that deliver unbreakable security without constant maintenance hassles. The Godrej Astro EXS+ 1CK 63mm rim lock solves these pain points with its robust stainless steel build, 63mm backset, and Milano Bronze finish. Designed for single and double doors, this 1CK model (one cylinder, one knob) offers key operation from outside and knob from inside, making it ideal for entrance doors in wooden or sliding setups.

Contractors in Mumbai or Delhi face rusty locks failing during monsoons, while DIY homeowners struggle with cheap imports jamming after months. This Godrej lock withstands India's humid climate, weighs just 1.5kg, and measures compactly at around 131mm length, 87mm width, and 48mm height for seamless installation on doors 30-90mm thick.

Key Features of Godrej Astro EXS+ 1CK

EXS+ Technology for Pick-Proof Security

The standout EXS+ mechanism uses 16 angular pins and up to 200 crore key combinations, making duplication nearly impossible. Forget worries about thieves picking locks during late-night site visits—this tech ensures smooth, reversible operation without sticking.

Premium Nickel-Silver Keys and Durable Body

Keys crafted from rustproof, bend-resistant nickel-silver alloy last years under daily use. The concealed stainless steel body with electroplated Milano Bronze finish resists corrosion, perfect for coastal areas like Chennai or Kerala where salt air wreaks havoc on standard locks.

Convenient 1CK Design

Operate effortlessly: key from outside for security, knob from inside for quick access. The 63mm backset fits standard Indian doors, and hold-back facility prevents accidental lockouts—a common frustration for busy contractors rushing between jobs.

Versatile for Sliding and Double Doors

Built for left/right-handed inside-opening doors, it handles sliding and double-door setups common in Indian apartments and bungalows. Dimensions of 17x20x8.5cm ensure it mounts flush without bulky protrusions.

  • Backset: 63mm for precise fit
  • Finish: Milano Bronze (also available in Ruby Red variants)
  • Weight: 1.5kg—light yet tough
  • Warranty: 1 year against manufacturing defects
  • Suitable doors: 30-90mm thick, wooden or metal

Real-World Benefits for Indian Users

DIY enthusiasts in Bangalore often drill new holes for ill-fitting locks, wasting time and wood. The Godrej Astro EXS+ 1CK 63mm installs in under 30 minutes with basic tools—no special drilling needed. Contractors building row houses in Pune appreciate the aldrop-style privacy bolt equivalent, blocking outside access even with keys for added family safety.

Benefits extend to longevity: unlike flimsy local brands that seize in dust-heavy Rajasthan sites, this lock's angular pins and strong sheet metal body deliver seamless operation for 10+ years. Homeowners save on replacements, while the sleek Bronze finish elevates door aesthetics without painting.

For high-traffic commercial spaces like small shops in Kolkata, the tamper-proof design deters break-ins, protecting inventory overnight. Reduced maintenance means fewer callbacks for pros, boosting efficiency on tight project deadlines.

Practical Use Cases

Residential Entrance Doors

Families in high-rise societies face unauthorized entries from duplicate keys. Install this on main doors for 21mm double-throw bolt strength, ensuring kids and elders stay safe.

On under-construction villas in Hyderabad, temporary plywood doors need quick, reliable locks. The hold-back feature lets workers exit freely without relocking every time.

Buying Guide: Choosing the Right Godrej Astro EXS+ 1CK

Select based on door type first: measure backset (63mm standard) and thickness (30-90mm). For humid regions, prioritize Milano Bronze over shinier finishes to avoid tarnish.

Compare models: 1CK suits single-knob needs; opt for 2C if both sides need keys. Check weight (1.5kg ideal for easy handling) and verify stainless steel construction for anti-theft pins.

Factor Recommendation

Best For Entrance, sliding, double doors

Budget tip: At affordable pricing, it outperforms pricier imports. Buy from trusted sellers for genuine warranty. Test knob smoothness on-site—smooth turn means quality pins.

Pro advice for contractors: Stock multiples from the Drill Machines Collection supplier for bulk site needs.

Installation Tips for Flawless Setup

Mark 63mm backset from door edge. Use a drill bit matching latch size—pair with Godrej-compatible bits. Secure with provided screws; test key turn before final fix. For double doors, align both locks at same height.

Common pitfall: Misaligned strike plate causes jamming. Shim if needed for perfect bolt throw. DIYers, watch for concealed body to avoid visible screws spoiling looks.

Maintenance for Longevity

Wipe with dry cloth monthly to prevent dust buildup. Lubricate pins yearly with graphite powder—no oil, as it attracts grime in Indian climates. Avoid forcing keys; if stiff, clean pins.

This routine keeps the Godrej Astro EXS+ 1CK 63mm performing like new, saving repair costs.
