How to Repair a Sticking Key on My Flute

A sticking key is one of the most common flute problems and can quickly make playing frustrating. Keys may feel slow to lift, hesitate, or make a soft “pop” sound when released. At Woodwind London, we see this issue daily, and in many cases it can be resolved quickly — especially if addressed early.

Here’s how to diagnose and safely deal with a sticking flute key.

1. Identify which key is sticking

Press each key slowly and watch how it moves. If one key lifts later than the others or feels tacky, the problem is usually localised to that pad or mechanism.

2. Remove moisture from the pad

Moisture is the most common cause of sticking keys.

Safe fix:

• Place a clean piece of cigarette paper (no glue or ink) under the pad

• Gently close the key

• Pull the paper out slowly

This absorbs moisture without damaging the pad. Avoid tissues — they leave fibres behind.

3. Remove residue

Sugar, oils, or lip balm residue can make pads sticky. If moisture removal doesn’t help, a technician can clean the pad surface safely. Avoid liquids or alcohol at home — these damage pads.

4. Check for sluggish mechanism

If the key feels slow rather than sticky, the issue may be mechanical:

• Weak or displaced spring

• Dry or slightly misaligned rod

• Compressed cork or felt

These require professional adjustment.

5. When home fixes aren’t enough

If the sticking returns repeatedly, or multiple keys are affected, your flute likely needs a pad reseat, spring regulation, or full service. Leaving it unresolved can lead to air leaks and larger repair costs.
