PKA Patcher
Use this tool to patch activity timer variables inside a Packet Tracer .pka / .pkt file — directly in your browser.
How it works
The file is decrypted to XML, the selected variables are patched in-memory, and the result is re-encrypted and downloaded as a new .pka file. Nothing is stored server-side.
Patchable variables
| Label | XML attribute | Description |
|---|---|---|
| Expired Activity Bypass | COUNTDOWN_EXPIRED | 0 = not expired / 1 = expired. Uncheck Mark as expired inside the card to clear the expiry flag (0) and bypass the check. |
| Default Time | COUNTDOWNMS | Total activity timer duration in milliseconds. |
| Time Left | COUNTDOWNLEFT | Remaining countdown time in milliseconds. |
Tips
- Tick only the patches you want to change; unticked patches are left as-is in the file.
- For Default Time and Time Left, enter hours, minutes and seconds — the tool converts them to milliseconds automatically.
- Set Time Left equal to (or greater than) Default Time to effectively reset the timer.
- To bypass an expired activity, uncheck Mark as expired under Expired Activity Bypass.
