How to Unlock Daikin AC Remote — Remove Child Lock
Follow these 5 steps to unlock your Daikin AC remote in under 10 seconds. No tools needed.
Step-by-Step Unlock
Check your remote shows "LOCK" on the display
Look at the LCD screen on your Daikin remote. If you see "LOCK" or a lock icon, the child lock is active.
Point the remote at the AC indoor unit
Stand within 3–4 metres of your AC and aim the remote directly at the indoor unit's receiver panel.
Press CANCEL + FAN simultaneouslyKEY STEP
Use two fingers to press and hold both CANCEL + FAN buttons at the exact same time.

Do not release the buttons early. Keep holding until the "LOCK" indicator vanishes from the display.
Test any button — remote should now respond
Press Temperature +/– or Mode. Your Daikin AC should respond immediately confirming the unlock.
Didn't Work? Try These:
Check batteries
Weak or dying batteries prevent button combinations from registering. Replace with fresh AAA alkaline batteries and try again.
Try the combination twice quickly
Some remotes need a rapid double-attempt. Press the combo, release, wait 2 seconds, then press again.
Check your model manual
Some Daikin models use a different button combination. Search "[your model number] child lock" in the manual or online.
Quick FAQ
Q: What does LOCK mean on Daikin AC remote?
LOCK stands for Child Lock. It prevents accidental temperature changes by disabling all remote buttons. It is NOT an error — it is a safety feature built into every modern AC remote.
Q: Will removing child lock reset my AC settings?
No. Removing child lock only re-enables the buttons on your remote. Your temperature, timer, mode, and fan speed settings remain completely unchanged.
How to Unlock Daikin AC Remote — The 60-Second Fix
To unlock a Daikin AC remote, press and hold the Temp+ and Temp– buttons together for 5 seconds. The "LOCK" indicator on the display will disappear, confirming the remote is unlocked. If that doesn't work, try holding Cancel + Temp+ together, or remove the batteries for 5 minutes and reinsert fresh ones.
Temp+ and Temp– (Primary Fix)
Hold both temperature arrow buttons simultaneously for 5 seconds — works on most Daikin inverter models including FTHT, FTKF, JTKJ series
Cancel + Temp+ Combination
Hold Cancel and Temperature Up together for 5 seconds — alternative method for older Daikin models and window AC units
Battery Reset
Remove both batteries, wait 5 minutes, reinsert fresh ones — universal reset method for any Daikin remote model
What does "LOCK" mean on Daikin remote? "LOCK" (or CL on some models) stands for Child Lock — a built-in safety feature that disables all remote buttons. It is not a hardware fault. It can be disabled with the Temp+ + Temp– combination in seconds.
Daikin online controller users: If your Daikin AC supports the Daikin Online Controller app, you can control temperature, mode, and fan speed from your smartphone even when the physical remote is locked.
4 Methods to Unlock Daikin AC Remote
Try in order — Method 1 (Temp+ + Temp–) works on most Daikin models. Method 3 (battery reset) is the universal fallback.
Temp+ and Temp– Button Combination
This is the primary unlock method for all Daikin AC remotes. It works reliably on the FTHT, FTKF, JTKJ, FTKG, and FTXM inverter series — the most widely sold Daikin models in India.
Hold both temperature arrows simultaneously for 5 seconds — primary unlock for all Daikin inverter series
Hold Cancel and Temperature Up together for 5 seconds — works on older Daikin models and Window ACs
Hold Temp+ and Temp– continuously for 5 seconds without releasing. The 'LOCK' text will vanish from the LCD and a short beep from the indoor unit confirms the child lock has been removed.
Pinhole Reset Button
Several newer Daikin AC remotes include a small reset pinhole on the back panel. This wipes all firmware states including child lock with a single hardware reset.
- 1
Flip the remote over and examine the back panel near the battery cover
- 2
Look for a tiny pinhole often labeled 'RESET' — may require close inspection
- 3
Insert a straightened paperclip, SIM ejector pin, or thin sewing needle into the hole
- 4
Press and hold for 5–10 seconds until the display flashes blank or restarts
- 5
Test all buttons — the remote should now respond with no lock state active
Note: Not all Daikin remotes have a reset pinhole. 2023+ Daikin inverter models are more likely to include this feature. If absent, use the battery removal method.
Battery Removal Reset
Removing both batteries completely drains the remote's internal capacitor, resetting all firmware states including child lock. This universal method works on every Daikin remote model.
- 1
Slide open the battery compartment cover on the back of the Daikin remote
- 2
Remove both AAA batteries completely — replacing just one is not enough
- 3
Wait a full 5 minutes — a 30-second wait won't fully discharge the internal capacitor
- 4
Insert two brand new AAA 1.5V alkaline batteries (avoid rechargeable ones)
- 5
Test the remote — all buttons should now respond normally without any lock
Note: Fresh alkaline batteries are important. Weak batteries cause erratic microcontroller behaviour on Daikin remotes — a leading hidden cause of persistent LOCK activations.
Disable Child Lock (LOCK Feature)
If the Daikin remote LCD shows 'LOCK', the Child Lock is active. This is a deliberate safety feature — not a malfunction — that prevents accidental temperature or mode changes.
- 1
Look at the remote's LCD screen and confirm 'LOCK' text or a padlock icon is visible
- 2
If LOCK is showing, do NOT replace batteries first — the button fix is faster
- 3
Press and hold Temp+ and Temp– buttons simultaneously for 5 seconds
- 4
Listen for a short beep from the Daikin AC indoor unit — this confirms child lock is off
- 5
The 'LOCK' indicator should disappear from the display
- 6
Test by pressing Temp Up or Mode button — the remote should now work fully
Note: Daikin remotes typically activate child lock when Temp+ and Temp– are pressed together — common when the remote is face-down on a surface or accidentally squeezed.
Fix Daikin AC Remote in 10 Seconds
Hold Temp+ + Temp– together for 3–5 sec to unlock
Hold Temp+ + Temp– buttons
Press both Temperature Up and Temperature Down simultaneously on your Daikin remote
Keep holding 5 seconds
Maintain both buttons pressed until the LOCK indicator disappears from the display
Test the remote
Press any button — your Daikin AC should now respond normally
If the above doesn't work, try these alternatives:
How to Remove Child Lock on Daikin AC Remote
The "LOCK" display on a Daikin AC remote means Child Lock is active. This is a built-in safety feature, not a fault. It disables all remote buttons to prevent unauthorized changes to AC settings.
- 1
Look at the remote's LCD screen and confirm 'LOCK' text or a padlock symbol is visible
- 2
If LOCK is showing, do NOT replace batteries first — the button combination is faster
- 3
Press and hold Temp+ and Temp– buttons simultaneously for 5 seconds
- 4
Hold until you hear a short beep from the Daikin indoor unit — lock is now off
- 5
The 'LOCK' text should disappear from the remote's LCD display

Why does Child Lock activate on Daikin?
Daikin remote layouts on the BRC series and FTHT models place Temp+ and Temp– buttons close together. When the remote is placed face-down, pressed in a bag, or accidentally squeezed during handling, both buttons can be pressed simultaneously — activating child lock. It's a design characteristic common to Japanese AC brands.
What Daikin Child Lock Prevents
Why Does Daikin AC Remote Get Locked?
Knowing the root cause helps prevent the issue from repeating
Child Lock Accidentally Activated
65% of casesThe top cause. Daikin remote layouts on FTHT and BRC series place Temp+ and Temp– buttons close together, making accidental simultaneous pressing easy — especially when the remote is on a surface or in a pocket.
Accidental Long Press
18% of casesHolding temperature buttons for too long while adjusting settings can inadvertently trigger the child lock on Daikin remotes, particularly on membrane-style button models.
Low Battery or Battery Glitch
12% of casesVoltage drops from weak batteries can cause the Daikin remote's microcontroller to glitch and randomly engage child lock. Replacing batteries often solves persistent LOCK issues.
Firmware / Software Glitch
5% of casesIn rare cases, a firmware anomaly in the remote's microcontroller creates a stuck lock state. The 5-minute battery removal reset clears this completely and reliably.

- ›This performs a full hardware reset, clearing all firmware lock states
Daikin Remote Display Blank / No Screen?
Check and replace the batteries
- ›Open battery cover and confirm both AAA batteries are correctly seated
- ›If old or corroded, replace both with fresh 1.5V AAA alkaline batteries
- ›Daikin remotes are sensitive to voltage — use standard alkaline, not rechargeable
Clean battery contacts
- ›Look for white or greenish corrosion residue inside the battery compartment
- ›Gently clean metal contact points with a dry cotton swab
- ›Reinsert fresh batteries after cleaning the contacts
Daikin Remote Buttons Not Responding (Display ON)?
Verify no Child Lock active
- ›Check for 'LOCK' or padlock icon — even a faint indicator means lock is active
- ›Hold Temp+ + Temp– for up to 7–8 seconds on stubborn cases
Test the IR signal
- ›Open your phone's front camera and press any remote button while pointing at lens
- ›If you see no purple/white light flash from the remote's top, IR LED may be faulty
- ›Faulty IR LED means the remote sends no signal — replacement is the fix
Check the AC receiver
- ›Wipe the indoor unit's dark signal receiver window with a dry cloth
- ›Operate the remote within 3 metres pointing directly at the unit
- ›Strong sunlight hitting the receiver window can block IR signals entirely
Nothing worked? Contact Daikin AC Service
If all combinations, battery reset, and pinhole reset have failed, the remote's IR transmitter or microcontroller may be physically damaged. Contact Daikin Customer Care at 1800-209-4454 or purchase a genuine replacement remote (₹500–800) from Amazon, Flipkart, or a Daikin authorized service center.
Daikin AC Remote Lock — Everything You Need to Know
Daikin is the world's largest AC manufacturer and among the most popular premium AC brands in India. The Daikin remote LOCK error (Child Lock) is one of the most searched AC remote issues in India, particularly among users of the FTHT 60, FTKF series, and JTKJ inverter models.
