If you’re using a Royal Kludge RK61 keyboard and find that your number keys are not working, you’re not alone. Many RK61 owners run into this issue—often without clear answers or solutions. This guide will help you understand why this happens, how to fix it, and what you can do if specific number keys (from 1 to 0) or their shifted versions (! to )) aren’t responding. We’ll look at all 61 keys on the RK61 to make sure you have a complete troubleshooting resource.
Understanding The Rk61’s Number Key Problem
The RK61 is a popular 60% mechanical keyboard, which means it’s compact and lacks a dedicated number row or numpad. Instead, all number keys are shared with the top row of letter keys and require different layers or function keys to access. This can confuse users, especially if the keyboard’s layers or modes are set incorrectly. Sometimes, the problem is as simple as a wrong setting, but sometimes it points to a hardware issue.
Quick Rk61 Keyboard Overview
Before you start troubleshooting, remember that the RK61 has:
- 61 keys total
- No dedicated number pad
- Numbers (1-0) are on the top row, sharing keys with symbols and function commands
- Layer switching via the Fn key
Knowing this will help you understand the solutions below.

Why Number Keys Might Stop Working
There are a few main reasons:
- Layer confusion: The keyboard has multiple layers, and number keys may be on a different layer.
- Function lock: If Fn lock is on, number keys may not type numbers.
- Firmware issues: Outdated or corrupt firmware can cause key malfunctions.
- Physical damage: Spilled drinks or hard impacts may damage circuits.
- Bluetooth/connection errors: Wireless mode problems can affect key response.
- Driver/software problems: Incorrect drivers or software settings can block keys.
- Sticky keys or debris: Dirt under the switches can stop keys from working.
Step-by-step Troubleshooting For Each Number Key
Let’s walk through each number key (1-0), their shifted symbols (! To )), and all 61 keys on the RK61 to spot specific issues.
1. Key 1 (!)
- Check if “1” or “!” registers when you press Fn+1.
- If not, test on another device.
- Clean the switch if it feels sticky.
- If still not working, there may be a hardware fault.
2. Key 2 (@)
- Try Fn+2 for “2” and Shift+2 for “@”.
- Ensure your keyboard is in the correct mode (Windows/Mac).
- If only one symbol works, it’s likely a software or mapping issue.
3. Key 3 ()
- Press Fn+3 and Shift+3.
- If nothing happens, check for stuck keys or firmware errors.
4. Key 4 ($)
- Make sure Fn+4 and Shift+4 produce the correct results.
- If the key is not working, update your keyboard firmware.
5. Key 5 (%)
- Test both numbers and symbols.
- If both fail, try resetting the keyboard to factory settings.
6. Key 6 (^)
- Some users find this key fails in Bluetooth mode.
- Try switching to USB cable and test again.
7. Key 7 (&)
- If “7” or “&” won’t type, double-check keyboard language settings.
8. Key 8 ()
- Problems here may be due to stuck debris.
- Remove the keycap and gently clean the area.
9. Key 9 (()
- If only “9” or “(” fails, try the keyboard on a different computer.
10. Key 0 ())
- “0” and “)” are often on the same key.
- If both are dead, it’s likely a physical or PCB issue.
11. Q
- Confirm that Q types correctly.
- If Q works but the number row above does not, it’s probably a layer or Fn problem.
12. W
- Same check: If Q and W both work, but 1 and 2 do not, focus on function layer troubleshooting.
13. E
- E is on the second row. If E works but 3 does not, the issue is probably not physical.
14. R
- If only the number row fails, check for firmware updates.
15. T
- If T and the number keys above it fail, check for PCB line issues (rare).
16. Y
- If Y is fine but 6 above isn’t, try reseating the switch if your RK61 is hot-swappable.
17. U
- U not working? Check for debris or damaged switch.
18. I
- If I and 8 both fail, there may be a shared circuit problem.
19. O
- O issues may also affect 9 and 0 if it’s a row-level fault.
20. P
- If P is fine and 0 isn’t, the issue is likely isolated to the number key.
21. A
- A is not directly related to number keys but check for full-row issues.
22. S
- S should work independently unless a large section of the keyboard fails.
23. D
- If D and 3 both fail, consider a firmware or mapping issue.
24. F
- F failures are rare; if F is fine but 4 isn’t, focus on the number row.
25. G
- G is not linked to number keys but test for full keyboard response.
26. H
- H and 6 share a column; if both fail, test with software like Switch Hitter.
27. J
- J failures are not usually related to number issues.
28. K
- K and 2 are not linked but check for firmware bugs.
29. L
- L’s failure along with 9 or 0 may mean a PCB trace problem.
30. ;
- If the semicolon works, but the number row above doesn’t, check Fn lock.
31. ‘
- Apostrophe issues are unrelated unless many keys are unresponsive.
32. Z
- Test Z for full-row check.
33. X
- X is not related to numbers but test for overall keyboard health.
34. C
- If C is fine, but 3 fails, it’s likely a layer problem.
35. V
- V’s failure is rare and not related to numbers.
36. B
- B not working? Test full keyboard for broad issues.
37. N
- N failures are not usually linked to the number row.
38. M
- M and 0 are not related but test if many keys fail together.
39. ,
- If comma works, number row should not be physically blocked.
40. .
- Period issues are unrelated to numbers.
41. /
- Slash not working can indicate a firmware problem if other keys are also failing.
42. Tab
- If Tab fails, test the entire row, as it may signal a PCB issue.
43. Caps Lock
- Caps Lock should not affect number row performance.
44. Shift (left)
- Shift is required for symbols (!, @, etc.). If Shift doesn’t work, symbols won’t type.
45. Ctrl (left)
- Control key issues are unrelated to number keys.
46. Win
- Windows key should not affect number keys but check for system-level shortcuts.
47. Alt (left)
- Alt is not related unless you use special input methods.
48. Space
- Space issues are unrelated to number row.
49. Alt (right)
- Same as left Alt.
50. Fn
- Fn key is crucial. If it fails, you cannot access the function layer, blocking number keys.
- If Fn is stuck, number keys may act as F1–F12 or other functions.
51. Ctrl (right)
- Not related to numbers.
52. Shift (right)
- Needed for symbols. If it’s dead, you can’t type !, @, etc.
53. Enter
- Enter failure may indicate a broader PCB issue.
54. Backspace
- Backspace is not directly related but test for response.
55. Delete
- Delete problems are unrelated unless part of a larger row failure.
56. Arrow Up
- Test arrow keys for firmware issues.
57. Arrow Down
- Arrow problems may appear if firmware is corrupted.
58. Arrow Left
- Left arrow unrelated to number row.
59. Arrow Right
- Right arrow unrelated.
60. Esc
- Esc not working may point to a firmware or full-row issue.
61. Menu/function Key
- This key can sometimes trigger different layers or functions. If mapped incorrectly, number keys may be affected.
Common Fixes For Rk61 Number Key Issues
Here are the most effective steps:

Comparing Wired Vs Bluetooth Mode For Number Key Issues
Some users experience problems only in wireless mode. Here’s a quick comparison:
| Mode | Common Problems | Fixes |
|---|---|---|
| Wired | Rare key failures, usually firmware | Update firmware, reset keyboard |
| Bluetooth | Key lag, number row not responding | Switch to wired, re-pair Bluetooth |
Non-obvious Insights Most Miss
- Layer confusion is common: Many people do not realize that pressing Fn puts the RK61 into a different layer, which can make the number keys act as F1–F12 instead of numbers. Always check your layer state before troubleshooting.
- Firmware mismatches happen: If you update your computer but not your keyboard’s firmware, the keys might not match the new drivers, causing number key failures. Check for firmware updates regularly.
