Why does my hair straightener lock function seem stuck?

If the lock function will not release or feels jammed, the plates may be under tension, the mechanism may be misaligned, or residue may be blocking the latch. Do not force it. If the straightener has been dropped or the lock no longer moves at all, stop using it.

Safe checks

1. Unplug the appliance and let it cool completely. Expected result: the lock should be easier to test once the unit is cold.
2. Clear away any hair, dust or product residue around the hinge and latch. Use only a soft cloth on the cold appliance. Expected result: the mechanism should move more freely.
3. Open and close the plates gently without twisting the handles. Expected result: the lock should release and engage without resistance.
4. Check whether the plates line up evenly. Expected result: aligned plates should help the lock move normally.

Stop using it if...

Stop using the straightener if the lock remains jammed, if the mechanism snaps unexpectedly, or if the plates will not sit flush. Do not pry the lock open with tools.

What to do next

If the lock still seems stuck after cleaning and cooling, contact the retailer or store where it was purchased for guidance on the next steps.
