Step-by-step guide to program Iveco Daily (2011-2019) keys using LAUNCH X431 scanner. Covers prerequisites, PIN retrieval, Add Key & All Keys Lost procedures, and troubleshooting.

Published: June 21, 2026

Quick Answer / Key Takeaway

To program an Iveco Daily (2011–2019) key with a LAUNCH X431 scanner, you need a compatible blank transponder key, the vehicle’s security PIN (usually 4 or 5 digits), and an updated X431 diagnostic tool. Connect the scanner to the OBD-II port, select Iveco > Daily, navigate to Immobilizer > Key Programming, enter the PIN, and follow the on-screen prompts. The process works for adding a key (requires one working key) or performing an “All Keys Lost” procedure.

Understanding the Iveco Daily Immobilizer System (2011‑2019)

The Iveco Daily uses a transponder-based immobilizer system starting from the 2011 model year and continuing through 2019. Here’s what you need to know:

Transponder keys – Each key contains a small chip (typically an ID46 for 2011‑2017 models and an ID47 for 2018‑2019 models). The chip stores a unique identification code that the immobilizer control unit (ICU) must recognize before allowing the engine to start.
Immobilizer control unit (ICU) – This module is usually located behind the dashboard or integrated with the body control module (BCM). It communicates with the engine ECU via the CAN bus, and it stores up to eight key codes in its memory.
Key memory slots – You can add or remove keys using a diagnostic tool like the LAUNCH X431. Each key occupies one slot; when all slots are full, you must delete an old key before adding a new one.
Security PIN – A unique code is required to authorize programming. You can often find it in the vehicle’s service booklet, on a plastic tag attached to the spare key, or by using the X431’s automatic PIN retrieval function (requires a paid subscription). Without the PIN, you cannot proceed.

Important: The 2011‑2019 Iveco Daily uses a “secret” key learning procedure that varies slightly between early and late models. The LAUNCH X431 handles these differences automatically as long as you have the latest software update.

Prerequisites Before Programming

Before you begin, gather the following items and verify each condition:

Item	Requirement
LAUNCH X431 scanner	Any model with Iveco software (e.g., X431 V+, PRO5, PAD VII). Ensure the tool is updated to the latest version that includes Iveco Daily support (software version 2025 or later is ideal).
Blank key(s)	Must be correctly cut for the vehicle’s lock tumblers and contain a compatible transponder chip. Use an ID46 for 2011‑2017, ID47 for 2018‑2019, or a universal ID46/ID47 blank.
Vehicle security PIN	Obtain from the dealer, previous key tags, or via the X431’s PIN read function. The PIN is usually 4 digits, but some 2019 models use a 5‑digit code.
At least one working key	For standard “Add Key” procedure, you need one existing working key. For “All Keys Lost,” you can start without any, but the tool may require online authorization.
Stable 12V battery	Low battery voltage is the most common cause of programming failure. Connect a battery maintainer or charger while working.
X431 internet connection	Many functions (PIN retrieval, All Keys Lost) require an active subscription and internet access on the X431.

Step-by-Step Guide to Program a Key with LAUNCH X431

Follow these steps carefully. The exact prompts may vary slightly depending on your X431 model, but the general sequence is consistent across the 2011‑2019 Iveco Daily.

Prepare the vehicle – Insert any existing working key into the ignition and turn it to the ON position (do not start the engine). Leave the key in this position.
Connect the scanner – Plug the LAUNCH X431 into the OBD-II port located under the dashboard on the driver’s side. Turn on the scanner and wait for the system to boot.
Select the vehicle – From the main menu, choose Iveco, then Daily, and select the appropriate model year range (e.g., “Daily 2011‑2019” or “Daily (Euro 5/6)”). The tool may auto‑detect the version; confirm the VIN when prompted.
Navigate to immobilizer functions – Go to Immobilizer or Security (sometimes under Special Functions > Key Programming). The menu name can differ; look for any option that mentions keys or immobilizer.
Choose the operation – Select Add Key if you have at least one working key. Select All Keys Lost if you have no working keys. The tool will then request the PIN code.
Enter the PIN – Type the 4‑digit (or 5‑digit) code using the on‑screen keypad. Confirm the entry. If the PIN is correct, the scanner will establish a secure link with the immobilizer.
Follow the on‑screen prompts – The X431 will guide you through a sequence of ignition on/off cycles and key changes. A typical “Add Key” procedure goes like this:
- Insert the first working key, turn ignition ON, wait for confirmation.
- Remove that key and insert the new blank key within 10 seconds.
- Turn ignition ON again; the tool will program the chip.
- Wait for the message “Key programmed successfully.”
Test the new key – Remove the newly programmed key and try starting the engine. The engine should crank and run normally. If it starts but stalls immediately, the transponder may not be recognized – try repeating the process.
Program additional keys – If you need to program more than one key, stay in the same menu and repeat steps 7 and 8 for each additional key. Do not exit the immobilizer menu until all keys are done.
Exit and disconnect – Turn the ignition off, disconnect the X431, and verify that all keys (old and new) can start the vehicle.

Note on “All Keys Lost”: This procedure often requires a longer wait period (e.g., 30–60 seconds) after inserting the new key and turning the ignition ON. The X431 will display a countdown timer. Do not move the key or disturb the connection during this time.

Troubleshooting Common Issues

Even with careful preparation, you may run into problems. Here’s how to handle the most frequent ones:

“Cannot communicate with immobilizer” – First, check that the X431 has the latest software update. Next, ensure the OBD connector is fully seated and try a different OBD cable or adapter if available. If communication still fails, inspect the vehicle’s OBD fuse (typically a 10A fuse in the dashboard fuse box) and the immobilizer fuse.
“PIN code incorrect” – Double‑check the code. Common default PINs include 1234, 0000, or the last four digits of the VIN. If you retrieved the PIN via the X431, try running the retrieval function again – sometimes the code is displayed with an extra digit. For 2019 models, a 5‑digit code is common.
“Key not learned” or programming fails midway – The most likely culprit is an incompatible transponder chip. Use a brand‑new, uncut blank key with the correct chip (ID46 for 2011‑2017, ID47 for 2018‑2019). Also, low battery voltage can cause failure; connect a battery maintainer and retry.
“All Keys Lost” procedure does not work – Some X431 versions require a higher‑level authorization for this function. You may need to log in with a dealer‑level subscription or contact LAUNCH support to obtain a temporary password. If your subscription doesn’t include “All Keys Lost,” you’ll need a locksmith or dealer.
Engine starts but immediately stops – The immobilizer is seeing the key but not validating the transponder. Try holding the key in the ignition with the engine off for 60 seconds after the programming confirmation. This can force the immobilizer to finalize the learning process. If that fails, repeat the programming cycle from the beginning.

Frequently Asked Questions
