What This Guide Helps With
This guide helps resolve the alarm condition “Keypad locked. Enter code to disable.” which prevents user interaction with the pump controls. This condition can restrict the ability to adjust or stop infusion therapy if not addressed promptly.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
- If infusion cannot be adjusted or stopped, transition therapy to a backup infusion device
- Confirm the patient continues receiving prescribed therapy without interruption
2. Verify the Reported Alarm and Behavior
- Confirm the alarm message is displayed: “Keypad locked. Enter code to disable.”
- Check if keypad inputs are unresponsive
- Determine if infusion is still running or paused
- Note when the alarm occurred (after STOP press, door open, or during operation)
3. Attempt Keypad Unlock
- Enter the facility-approved keypad unlock code
- Use authorized clinical or biomed override code if applicable
- Confirm keypad functionality returns after entry
4. Check for Accidental Lock Activation
- Determine if STOP was pressed while keypad lock was active
- Check if the cassette door was opened during a locked state
- Review device settings for keypad lock enablement
5. Verify Keypad Function After Unlock
- Test multiple keypad inputs
- Navigate menus and confirm responsiveness
- Simulate start/stop functions if safe to do so
6. Power Cycle if Unlock Fails
- Turn the pump OFF
- Disconnect from AC power briefly
- Restart the device and reassess keypad response
If the Problem Persists
If the keypad cannot be unlocked or remains unresponsive after these steps, external causes have been ruled out. Remove the device from service, label it Out of Service, and send for repair or bench evaluation. Persistent lock conditions may indicate keypad interface or control board failure.
Clinical Use Tip
Never troubleshoot or rely on a device with a locked or unresponsive keypad during active patient use. Always transfer the patient to a functioning device first.

Final Thought
Keypad lock alarms are often normal operational safeguards but must be resolved quickly to maintain control of infusion therapy. Always verify full functionality before returning the device to service and escalate appropriately if access cannot be restored.
That is successful troubleshooting.
