LG range displays LOC or a lock icon and buttons do not respond; oven and cooktop controls are disabled.

Safety first: This is not a hardware failure; no disassembly is required.

• Disable child lock: On most LG ranges, press and hold the Lock or Control Lock key for 3–5 seconds until the LOC indicator turns off. On some models, press and hold Clear/Off and 0 together.
• Check user manual: If unsure of the key combination, refer to the model-specific user manual for the child lock instructions.
• Stuck key: If LOC will not clear, check if any key is physically stuck. If so, the keypad may need cleaning or replacement.
