- Device & OS
- not provided
- Scenario
- Typing numbers or performing data entry using a Jelly Comb keyboard.
- Observed behavior
- Specific number keys fail to register input, indicating a potential hardware defect.
Ensure your keyboard is fully charged or has fresh batteries, and try connecting its USB receiver to a different port before concluding it is a hardware failure.
Test with an Alternative Keyboard and Contact Support
Isolate the issue to the keyboard hardware and reach out to the manufacturer for a replacement.
When specific keys stop working while others function normally, it is highly likely to be a physical hardware defect rather than a software issue. Testing with a secondary keyboard will confirm this.
Unplug the Jelly Comb keyboard or remove its wireless USB receiver from your computer.
Plug a different, known-working keyboard into the same computer.
Open a text document and test the specific number keys that were failing. If they work on the backup keyboard, your Jelly Comb device is defective.
Visit the official Jelly Comb support website to submit a warranty claim or request a repair or replacement.
Clean the Unresponsive Keys
Remove debris or dust that might be blocking the key switches and causing them to become unresponsive.

Frequently Asked Questions
Why are only specific number keys not working on my keyboard?
When only specific keys fail (like 5 and 6), it usually indicates a localized hardware failure, such as a damaged membrane circuit, a broken mechanical switch, or debris blocking the contact point.
Can a software update fix my unresponsive Jelly Comb keyboard keys?
If the issue is isolated to just one or two keys, it is rarely a software or driver issue. However, you can try reinstalling the keyboard drivers in your computer's Device Manager to completely rule out software glitches.
How do I type numbers if my keyboard is broken?
As a temporary workaround, you can use your operating system's built-in On-Screen Keyboard. On Windows, search for 'On-Screen Keyboard' in the Start menu; on Mac, enable the Accessibility Keyboard in System Settings.
