A dead remote on the WalkingPad C2 is more disruptive than on most walking pads, because the remote is the primary way to start, stop, and change speed in manual mode. The good news: in most cases the remote isn’t broken — it has a dead battery, lost its pairing, or the pad is in a mode where the remote isn’t expected to do anything.
This guide covers the full fix sequence in order: battery replacement, the official re-pairing method straight from the King Smith manual, the KS Fit app as a backup controller, and the mode/safety settings that can make a perfectly working remote seem dead.
Quick Answer: C2 Remote Not Working
| Question | Answer |
|---|---|
| How do I re-pair the C2 remote? | Restart the WalkingPad, then immediately press and hold the remote’s mode switch button; a beep confirms successful pairing. Keep the remote close to the pad’s LED display panel during the process. |
| What battery does the remote use? | A coin-cell battery — open the compartment and check the marking (most C2 remotes use a CR2032). Replace it if the remote shows no response. |
| Can I use the C2 without the remote? | Yes — the KS Fit app connects over Bluetooth and gives you full control, and automatic mode adjusts speed from your foot position without any remote at all. |
| Why won’t the remote do anything? | Dead battery, lost pairing, the pad is in standby or automatic mode, or another phone is holding the Bluetooth connection. |
| Does the safety key affect the remote? | Yes — the pad won’t start from any controller without the safety key in place, so a dead-feeling remote can actually be a missing key. |
What “Remote Not Working” Actually Looks Like on a C2
Before fixing, pin down the symptom — each one points to a different cause:
- Remote does nothing at all, no matter what you press → dead battery or lost pairing (most common).
- Remote worked, then stopped after the pad was unplugged or moved → lost pairing; re-pair it.
- Remote starts the pad but some buttons don’t respond → the pad may be in automatic mode, where speed is controlled by your foot position, not the remote.
- Remote works but the pad won’t start → check the safety key and whether the pad is in standby mode (the pad can appear “on” while the motor and sensor are intentionally unresponsive).
Fix 1: Replace the Remote Battery
Start here — it’s the cause more often than people expect, and it’s a two-minute job.
- Open the battery compartment on the back of the remote (it slides or twists off depending on the remote revision).
- Note the battery type printed inside — most C2 remotes use a CR2032 coin cell. Replace like-for-like; don’t guess with a different size.
- Insert the new battery with the correct polarity (+ side facing up as marked).
- Test immediately: point the remote at the pad’s LED display and press a button. You should see the display react or hear the pad beep.
If a fresh battery changes nothing, move to re-pairing — the remote and pad have likely lost their connection.
Fix 2: Re-Pair the Remote (Official Method)
The King Smith C2 manual gives an explicit pairing procedure for exactly this situation: *”If the remote controller has no response or you change a new one, the remote controller and walking device need to re-establish communication.”* Follow it exactly:
- Restart the WalkingPad — switch it off and back on.
- Immediately press and hold the mode switch button on the remote (don’t wait; the pad only listens for pairing right after startup).
- Keep the remote close to the LED display panel of the pad while holding — distance matters during pairing.
- Listen for the beep. The “Beep” sound confirms pairing succeeded.
- Test the START/STOP button to confirm the pad responds.
If you changed to a brand-new replacement remote, the same procedure applies — new remotes ship unpaired. If pairing fails repeatedly, make sure no other Bluetooth device (like your phone with the KS Fit app) is actively connected to the pad, since only one Bluetooth client can connect at a time.
Fix 3: Use the KS Fit App as an Alternative
The KS Fit app (King Smith’s companion app) connects to the C2 over Bluetooth and gives you start/stop, speed control, and workout tracking — a full remote replacement. This is your best fallback while waiting on a new battery or replacement remote.
- Make sure the pad is awake. An important C2 quirk: the pad sleeps and stops advertising over Bluetooth entirely when idle — this is its normal resting state, not an error. Wake it by switching the pad on or pressing a button; you may need the remote or panel for the first wake-up.
- Disconnect other Bluetooth clients. Only one device can hold the connection — if the app won’t pair, check that no other phone or tablet is connected to the pad.
- Connect through the KS Fit app and confirm you can start and adjust speed from your phone.

Fix 4: Check Modes and the Safety Key
The C2 has three control modes, and a working remote can appear dead in the wrong one:
- Manual mode (primary mode) — speed controlled by the remote’s START/STOP and +/- buttons. This is where beginners should operate.
- Automatic mode — the built-in pressure sensors read your foot position: step forward to speed up, step back to slow down. The remote’s speed buttons deliberately do less here. Switch with a short press of the mode switch button.
- Standby mode — the motor and sensor stop responding entirely, to prevent accidental starts. Enter it with a long press of the mode switch button. In standby, *no* controller will start the pad — press the mode button again to exit.
And the safety key: the pad will not operate without it in place, regardless of remote, app, or mode. If the remote “does nothing,” check the key before ordering parts. For the parallel generic guide, see walking pad remote not working.
WalkingPad C2 Error Code Reference
If your remote issue comes with a code on the display, the C2 manual defines these — note how the meanings differ from other brands (this is why brand-specific manuals matter):
| Code | Meaning (per C2 manual) |
|---|---|
| E01 | Upper control receives lower control data abnormally |
| E02 | Hall fault (motor sensor) |
| E03 | Software overcurrent protection |
| E04 | Locked rotor protection |
| E05 | Data received by the lower control is abnormal |
| E06 | Hardware overcurrent protection |
| E07 | Motor undervoltage protection |
| E08 | Motor overvoltage protection |
| E09 | Motor phase loss protection |
| E10 | Motor overload protection |
| E20 | Abnormal communication |
| E21 | Sensor failure |

Safety Stop-Points
- Burning smell, smoke, or arcing → unplug immediately and stop using the pad; escalate to King Smith support or a technician.
- Repeated overheating (pad hot, errors returning faster each session) → unplug, let it cool fully, and stop use until the cause is identified.
- The pad starts on its own or responds to buttons you didn’t press → keep clear of the belt, unplug, and treat it as an electrical fault, not a remote issue.
WalkingPad C2 Remote FAQs
The remote beeps the pad but the belt won’t start. What’s wrong?
The remote is fine — the pad is refusing to start. Check the safety key first, then confirm you’re in manual mode (not standby). If the display shows an error code, look it up in the table above.
Do I need to re-pair after changing the battery?
Usually not — the pairing is stored on the pad. But if the battery was dead for a long time or the pad was unplugged, re-pairing with the mode-switch method takes seconds and rules it out.
Can I buy a replacement C2 remote?
Yes — replacement remotes are sold through King Smith’s official channels and major marketplaces. A new remote will need the pairing procedure above before it works.
Why does the pad keep disconnecting from the app?
Remember the C2 sleeps and stops Bluetooth advertising when idle. If the app loses the pad after a pause, wake the pad first, then reconnect in the app. Also confirm only one device is connected at a time.
The remote works but the speed buttons do nothing in automatic mode. Is it broken?
No — that’s by design. In automatic mode, foot position controls speed and the remote’s speed buttons are secondary. Short-press the mode switch to return to manual mode for full remote speed control.
Should the remote be close to the pad for normal use?
For normal operation, a few meters is fine. Only during the *pairing* step does the manual require the remote to be close to the LED display panel.
Conclusion
A WalkingPad C2 remote that isn’t working is usually a dead battery, a lost pairing, or a mode mix-up — not a broken remote. Replace the coin-cell battery, re-pair by holding the mode switch button right after a restart until you hear the beep, and keep the KS Fit app in your pocket as a backup controller. If the pad itself still refuses to cooperate, check the safety key, exit standby mode, and look up any display code in the table above.
