Why You're Seeing This Problem
Remote Is Locked
Your AC remote display shows "CL" and all buttons are disabled. This is the Child Lock feature — not a hardware fault. It can be removed in seconds.
Fix CL error →Buttons Not Working
Pressing buttons on your AC remote but getting no response? Could be child lock, dead batteries, or IR transmitter issue. All are fixable.
Fix unresponsive remote →CL Showing on Display
"CL" stands for Child Lock. It's a safety feature that disables all remote buttons to prevent accidental changes. Use a button combination to remove it.
Remove child lock →Good to know: The AC unit itself continues to run normally while the remote is locked. Your cooling is not affected — only the remote buttons are disabled. You can also use the control panel on the AC unit directly while troubleshooting. See complete unlock guide for all brands
How to Remove Child Lock from AC Remote
"To remove child lock from an AC remote, press and hold the + and – buttons together for 3–5 seconds. If that doesn't work, try Mode + Temp or Swing + Temp, depending on the brand."
Hold + and – Together
Press Temp+ and Temp– simultaneously for 3–5 seconds. Most universal method across all brands.
Try Mode + Temp
Hold Mode and Temp+ together for 3–5 seconds. Works for Hitachi, Godrej, Voltas and others.
Remove Batteries
Remove both batteries, wait 5 full minutes, then reinsert fresh AAA cells. Always works.
Child Lock Is NOT a Hardware Fault
The remote is not broken. Child Lock is just a software setting. No repair, no service call needed — just the right button combination.
AC Keeps Running While Locked
Your AC unit continues to cool normally even with child lock on. Only the remote buttons are disabled. No setting is changed.
What Is Child Lock in AC Remote?
A Built-In Safety Feature
Child Lock is a deliberate feature found in almost all modern AC remotes. When activated, it completely disables all buttons on the remote — so no one can accidentally change temperature, mode, fan speed, or timer settings.
Designed for Households with Children
Prevents young kids from constantly changing AC settings — especially in bedrooms and living rooms. A single accidental button press can disrupt sleep or energy efficiency.
Used in Hotels and Offices Too
Hotels and offices use child lock to prevent guests or employees from changing preset temperature and mode settings — keeping the room at a fixed comfort level.
Present on All Major AC Brands
Voltas, LG, Hitachi, Blue Star, Lloyd, Godrej, Daikin, Samsung, Panasonic, Carrier — every major Indian AC brand includes child lock as a standard remote feature.

Why Child Lock Gets Enabled
Understanding the cause helps you prevent it from happening again.
Kids Playing with the Remote
Young children pressing multiple buttons simultaneously is the #1 cause of accidental child lock activation. The simultaneous button press is exactly what triggers it — making it an ironic outcome of the very problem it solves.
Fix: Use the standard unlock combination for your brand and store the remote out of children's reach.
Accidental Long Press / Button Combination
Picking up the remote while two buttons are being pressed, resting it face-down on a surface, or storing it in a bag with other objects pressing the buttons are all common triggers. The remote doesn't distinguish between intentional and accidental presses.
Fix: Hold the correct unlock combination for 3–5 seconds. Store remote face-up in a fixed location.
Low Battery Voltage Glitch
When battery voltage drops below a threshold (usually around 1.0V per cell), the remote's microcontroller becomes unstable and can enter unexpected states — including child lock. This often appears as CL activating overnight without anyone touching the remote.
Fix: Replace both batteries immediately with fresh 1.5V AAA alkaline cells. Do not use rechargeable NiMH.
Intentional Activation (Forgotten)
A family member, housekeeping staff, or technician may have intentionally enabled child lock to prevent accidental setting changes — and forgot to mention it or couldn't remember the unlock sequence. Common in homes with elderly members.
Fix: Same unlock combination applies. Ask household members if child lock was deliberately enabled.
How to Prevent Child Lock from Activating Again
Store remote face-up on a flat surface — never face-down
Use a dedicated remote holder or stand near your bed or sofa
Replace both batteries every 6–8 months proactively
Write your brand's unlock combo on a note and stick it near the AC
Avoid pressing buttons while cleaning or wiping the remote surface
If you need to enable child lock intentionally, tell everyone in the household
Troubleshooting — When Methods Don't Work
Advanced fixes for stubborn child lock or unresponsive remote issues.
Try a Different Combination
If + and – didn't clear CL, try Mode + Temp+ (for Hitachi, Godrej, Voltas) or Swing + Temp+ (for Lloyd, Blue Star). Each brand uses its own primary combo.
Hold Longer — Up to 10 Seconds
Some remote models require 7–10 seconds, not just 3–5. Keep holding firmly until the display changes or you hear a beep from the AC unit.
Battery Removal — The Guaranteed Reset
Remove both batteries and wait 5 full minutes before inserting fresh AAA alkaline batteries. This clears all firmware states without exception.
Use the Pinhole Reset (if available)
Check the remote's back panel for a small RESET hole. Insert a pin and hold 10 seconds. The display will go blank and restart with all settings cleared.
Nothing Worked? Contact Brand Service
If all 5 methods fail and the remote appears physically undamaged, the microcontroller may have a permanent fault. Contact your AC brand's toll-free helpline for support.

How to Remove Child Lock from AC Remote — Complete Guide
Child lock on AC remotes is one of the most searched AC problems in India, and also one of the most misunderstood. Millions of users search for 'remove child lock AC remote' or 'AC remote child lock fix' every month — believing their remote is defective or needs replacement. The truth is simpler: child lock (shown as 'CL' on the display) is a deliberate safety feature, not a malfunction. Removing it takes under 60 seconds once you know the correct button combination for your brand.
The concept of child lock in AC remotes works the same way as child locks on smartphones, television remotes, and microwave ovens — a specific button combination disables all inputs to prevent accidental changes. Indian AC brands have standardised around a few key combinations: Temperature+ and Temperature– together (the most universal), Mode + Temperature+ (used by Hitachi, Godrej, Voltas), and Swing + Temperature+ (used by Lloyd and Blue Star). LG stands out with its unique Timer + Min combination for Dual Inverter models.
Battery health is a critically important and frequently overlooked factor in child lock issues. When AAA batteries in an AC remote drop to around 40% charge, the remote may still display normally but deliver insufficient voltage for stable microcontroller operation. This manifests as phantom child lock activations (CL appearing without anyone pressing buttons), sluggish response, or buttons that work intermittently. The solution is always to replace both batteries simultaneously with fresh 1.5V AAA alkaline batteries — avoid rechargeable NiMH cells as their nominal 1.2V is insufficient.
For users whose child lock won't clear despite trying multiple combinations, the 5-minute battery removal method is a guaranteed solution for every single AC brand and model. This works because removing the batteries drains the remote's internal capacitor charge over 5 minutes, fully resetting the microcontroller's firmware state. When fresh batteries are inserted, the remote boots fresh with no lock states active. If even this fails, the remote has a hardware fault and requires replacement — genuine brand remotes cost ₹400–600, while compatible third-party options are available for ₹150–350.
