Is your mechanical keyboard registering multiple keystrokes when you only press a key once? You’re dealing with key chatter, a common but fixable issue that affects mechanical keyboards. In this comprehensive guide, we’ll walk you through everything you need to know about key chatter and how to fix repeating keys.
What is Key Chatter?
Key chatter occurs when a single keypress registers multiple times, resulting in repeated characters or commands. This frustrating issue can significantly impact your typing accuracy and gaming performance. While it might seem alarming at first, key chatter is often fixable without replacing your keyboard.
Common Causes of Key Chatter
Several factors can contribute to key chatter in mechanical keyboards:
- Dust and debris accumulation inside switches
- Dried-out switch lubricant
- Mechanical wear and tear
- Liquid damage
- Faulty switch contacts
- Incorrect firmware debounce settings
