How to Unlock AC Remote — The 30-Second Fix
To unlock an AC remote, press and hold the Temperature (+) and Temperature (–) buttons together for 3–5 seconds. The display will show "CL" disappear or a lock icon will turn off. If that doesn't work, try holding Mode + Temp simultaneously, or perform a battery reset by removing batteries for 5 minutes and reinserting them.
Press + and – Together
Hold both temperature buttons for 3–5 seconds until 'CL' disappears
Try Mode + Temp
If step 1 fails, hold Mode and any Temp button simultaneously for 5 seconds
Remove Batteries
Last resort: remove batteries for 5 minutes, reinsert to factory reset the remote
What does "CL" mean? CL stands for Child Lock — a safety feature that disables the remote to prevent accidental temperature changes. It is the most common reason why AC remotes appear "locked." The fix is simply re-pressing the same unlock combination.

4 Methods to Unlock AC Remote
Try these in order — Method 1 works on 80% of cases
Button Combination (Most Common)
Most AC remotes can be unlocked by pressing specific button pairs simultaneously. Try each combination one at a time, holding for 3–5 seconds each.
Hold both temperature arrow buttons together — works on Voltas, Blue Star, Lloyd
Works on Hitachi, Daikin, and Carrier models
Common on LG and Samsung models
Reset via Pinhole Button
Many modern AC remotes have a small reset pinhole, usually at the bottom or back of the remote. This performs a factory reset of the remote settings.
- 1
Locate the small pinhole labeled 'RESET' on the back or bottom of your remote
- 2
Insert a pin, toothpick, or SIM ejector tool into the hole
- 3
Hold for 5–10 seconds until the display blinks or resets
- 4
Re-pair the remote with the AC unit if required
Remove & Reinsert Batteries
Removing the batteries fully resets the remote's firmware, clearing any lock state. This works on all remotes regardless of brand.
- 1
Open the battery compartment (usually on the back of the remote)
- 2
Remove all batteries completely
- 3
Wait for at least 5 minutes — this ensures the capacitor fully discharges
- 4
Reinsert fresh batteries (AAA 1.5V is standard for most AC remotes)
- 5
Test the remote — it should respond normally now
Pro Tip: This also fixes remotes that work intermittently or have unresponsive buttons due to firmware glitches.
Disable Child Lock (CL Feature)
The Child Lock (CL) feature is a dedicated function built into most modern inverter ACs. When enabled, all remote buttons are disabled except the unlock sequence.
- 1
Look for the lock icon or 'CL' text on your remote's LCD display
- 2
If 'CL' is visible — the child lock is active
- 3
Press and hold the designated Child Lock button (check your manual) for 3–5 seconds
- 4
On many brands, pressing Temp + and Temp – together for 5 seconds disables it
- 5
The 'CL' indicator should disappear — remote is now unlocked
Pro Tip: Child Lock is intentionally hard to disable accidentally — which is why it can feel like the remote is broken when it's just locked.

AC Remote Still Locked After Trying All Combinations?
Try These StepsTry all combinations systematically

Your specific model may have a unique unlock combination. Search '[your model number] remote unlock' on Google.
AC Remote Showing "CL" — What It Means
Most Common IssueCL = Child Lock (not a malfunction)
"CL" does NOT mean the remote is broken. It means Child Lock mode is enabled — a deliberate feature to prevent accidental changes.
Why CL gets activated accidentally
Pressing multiple buttons simultaneously (e.g., setting a timer wrong) can accidentally trigger Child Lock on many remotes.
How to clear CL
Press and hold Temp + and Temp – together for 3–5 seconds. The 'CL' indicator should disappear from the display.
Understanding AC Remote Lock: Everything You Need to Know
AC remote child lock (CL) is a standard feature on virtually all modern inverter air conditioners sold in India. Brands like Voltas, LG, Blue Star, Hitachi, Daikin, Lloyd, and Panasonic all include this feature — and it gets activated more often than most people expect. A simple accidental simultaneous button press while adjusting temperature or timer settings is all it takes to trigger the lock.
The CL indicator doesn't mean your remote or AC is broken. It is a deliberate design decision by manufacturers to prevent children or anyone unfamiliar with the remote from accidentally changing temperature settings, turning off the AC, or activating unintended modes. In homes with young children, this feature can actually be very useful when intentionally enabled.
The most reliable universal unlock method across all brands is the battery reset: remove batteries and wait 5 full minutes before reinserting. This works because it fully drains the remote's internal capacitor, resetting all firmware states including any lock configuration. Unlike button combinations that vary by brand and model, the battery reset is guaranteed to work on any remote.
If your AC remote shows no CL indicator yet buttons still don't respond, the issue is likely not a lock — it may be a failing IR transmitter, dead batteries, or physical button damage. You can verify IR function using your smartphone camera: point the remote at the camera lens and press a button. If you see a flash from the remote tip on your screen, the IR is transmitting and the issue is with the AC's receiver or signal alignment.
