How to Add a Key to a Citroën Jumpy or SpaceTourer (2016+) Using LAUNCH X431

Last Updated: June 16, 2026

Quick Answer

Yes, you can add a new key to a 2016+ Citroën Jumpy or SpaceTourer using a LAUNCH X431 diagnostic tool. Connect the tool to the OBD-II port, select the vehicle model, navigate to the Immobilizer or Key Programming menu, enter the vehicle’s 4-digit security code (PIN), and follow the on-screen prompts. You’ll need a blank, uncut key, a stable internet connection, and an active IMMO license on your X431. The process typically takes 5–15 minutes. Important: If you have zero working keys, you must perform a separate “All Keys Lost” procedure, which is more complex.

Understanding the System & Requirements

The PSA Immobilizer System (2016+)

The second-generation Citroën Jumpy and SpaceTourer (and their Peugeot/Toyota siblings, the Expert and Proace) use a sophisticated immobilizer system built around the NEC/Renesas architecture. The immobilizer logic lives inside the BSI (Built-in Systems Interface) — the central electronics module that controls lighting, locks, windows, and the engine start function. The BSI talks to the engine ECU and the key transponder via the ignition ring antenna.

What does this mean for you? The BSI stores the list of authorized key transponder IDs. When you add a key, you’re telling the BSI to accept a new transponder. Without the correct security code (PIN), the BSI won’t allow any key programming.

You’ll need the following:

• Security Code (PIN): A 4-digit code (sometimes alphanumeric — A=1, B=2, C=3, D=4). It usually comes on a plastic card in the owner’s manual or a key tag. If you don’t have it, you can retrieve it via online services using your VIN. Never guess — entering the wrong code three times can lock the BSI for up to an hour.
• Correct Key Blank: You need a genuine PSA key blank or a high-quality aftermarket blank (e.g., JMA, IKEY, or OEM). The key must have both a correctly cut metal blade and a compatible remote fob. Most 2016+ Jumpy/SpaceTourer keys use a 3-button or 4-button remote.
• Working Key: For the “Add Key” procedure, you need at least one working key already in the system.

Equipment Checklist

Step-by-Step Guide: Adding a Key (One Working Key Present)

This procedure preserves all existing keys and adds a new one. It’s the most common scenario — you’ve lost one key and ordered a replacement.

Step 1: Prepare the Vehicle

1. Sit in the driver’s seat with all doors closed.
2. Insert the working key into the ignition and turn it to the ON position (ignition on, engine off). Do not start the engine.
3. Connect a 12V battery charger to the vehicle’s battery to maintain stable voltage during programming. A drop below 12.5V mid-procedure can corrupt the BSI memory.

Step 2: Set Up the LAUNCH X431

1. Power on the LAUNCH X431 tablet.
2. Connect the VCI (Vehicle Communication Interface) to the OBD-II port under the dashboard (driver’s side, near the fuse box).
3. Open the LAUNCH X431 Diag app.
4. Navigate: Diagnosis → European → Citroën.
5. Select the correct model: Jumpy (2016–) or SpaceTourer (2016–). If unsure, use VIN auto-detect.

Step 3: Enter the Immobilizer System and Select Function

1. Choose Immobilizer or BSI (Built-In Systems Interface).
2. Click Special Functions or Action Test.
3. From the list, select Key Programming or Add Key (wording varies by software version).

Step 4: The Programming Sequence

1. The X431 will prompt you to enter the Security Code (PIN). Type the 4-digit code carefully.
2. The tool then displays: “Insert the new key into the ignition and turn to ON.”
3. Action: Remove the working key from the ignition. Insert the new blank key (already cut) and turn it to the ON position.
4. The tool shows a waiting period — usually 30 to 60 seconds. During this time, the X431 communicates with LAUNCH servers to authorize the key.
5. When the tool displays “Programming Successful,” remove the new key.
6. Final test: Reinsert the original working key and start the engine. Then test the new key the same way. Also check the remote lock/unlock buttons.

Step-by-Step Guide: All Keys Lost (No Working Keys)

This scenario is much more involved. When you have zero working keys, the BSI has no known transponder to authenticate against. You must perform a full key learning — essentially wiping the BSI’s key memory and enrolling one or two new keys from scratch.

Important Differences

• The X431 requires online server authorization — this takes 1–3 minutes and depends on your subscription.
• You must have the correct PIN. There is no way around it.
• The BSI will reboot during the procedure. Dashboard lights may flicker, and the instrument cluster may go dark momentarily. Do not touch anything.

The Forced Learning Procedure

1. Connect the X431 and select the vehicle as described above.
2. Go to Immobilizer → Special Functions → All Keys Lost.
3. The X431 will request a server response. This is normal. Wait until the tool confirms that the server has authorized the procedure.
4. Enter the Security Code (PIN).
5. The tool instructs: “Insert the first new key and turn to ON.” Do so.
6. The X431 writes the transponder ID to the BSI. This takes about 30 seconds.
7. Remove the first key. If you are programming a second key, insert it and turn to ON. The BSI now learns the second transponder.
8. The tool finalizes the learning. The BSI may reboot — expect dashboard lights to flash. Do not touch anything until the X431 says the process is complete.
9. Test both keys: start the engine, check remotes.

Warning: If you only have one new key, program it as the first and only key. You cannot add a second key later without a working key unless you repeat the entire All Keys Lost procedure.

Troubleshooting Common Errors & Issues

Error: “Communication Failure with BSI”

• Likely cause: Low battery voltage or a poor connection at the OBD port.
• Fix: Connect a battery charger. Replug the VCI firmly. Make sure the ignition is fully in the ON position (some vehicles have an intermediate “accessory” position that won’t work).

Error: “Security Code Incorrect” (Even when you’re sure it’s right)

• Likely cause: You may have entered the radio code or a code for a different module. On some PSA vehicles, the immobilizer PIN is printed on a separate card, not the radio card.
• Fix: Retrieve the code using the VIN through a reputable online service (e.g., AutoKey Pro or Car-Key-Programmer). Remember: letters A, B, C, D correspond to numbers 1, 2, 3, 4.

Error: “Key Not Detected”

• Likely cause: Incompatible or defective key blank, or the key is not in learning mode.
• Fix: Hold the key closer to the ignition ring — the transponder reader is around the steering column. On some models, you must press the lock or unlock button on the new key before inserting it. Also, verify the blank has a compatible transponder chip (e.g., 46-chip for PSA).

Error: “Server Authorization Timeout”

• Likely cause: The X431 cannot verify your license or the vehicle data online.
• Fix: Check your X431 subscription status. Ensure you have a strong Wi-Fi signal. Try switching to a mobile hotspot. If the problem persists, contact LAUNCH support or your tool supplier.

The Importance of the Security Code (PIN)

The security code is the gatekeeper for any key programming on PSA vehicles. Without it, you cannot proceed.

• Where to find it: A plastic card in the glovebox or owner’s manual wallet, a tag attached to the keys, or a dealer lookup using the VIN. Online services like AutoKey Pro or Car-Key-Programmer can retrieve it for a small fee — you’ll need to provide proof of ownership (registration or ID).
• Penalty for failure: Enter the wrong code three times, and the BSI will lock you out for a period (30 minutes to 1 hour). Do not guess. If you’re unsure, get the code from a trusted source.

FAQ

Can I use a LAUNCH X431 to add a key to a 2023 Citroën Jumpy?

Yes, but make sure your X431 has the latest software. Model years 2020 and newer may use an updated protocol. Update your X431’s “IMMO” database before starting. Also confirm that you have enough credits in your subscription — newer vehicles sometimes require more credits.

Do I need to cut the key first?

Yes. The key blade must be mechanically cut to fit the ignition cylinder. A locksmith or hardware store can cut it based on your existing key or the VIN. The blank key must already be cut before you attempt programming — you cannot program an uncut key.

How much does it cost to add a key with an X431?

If you own the tool, the cost is minimal: a blank key ($15 to $50) plus a small token or credit fee for the X431 license (usually a few dollars per procedure). This is far cheaper than a dealership, which typically charges $200 to $400. For a more detailed breakdown of diagnostic tool costs, check out our guide on [link to article about OBD scanner features vs price].

Will this procedure delete my existing keys?

No — the “Add Key” function preserves all existing keys. It simply adds the new one to the BSI’s memory. However, the “All Keys Lost” function will delete all old keys and only recognize the ones you program during that session. If you have lost one key but still have another, always use “Add Key.”

My remote central locking stopped working after programming. Why?

The X431’s key programming function often only programs the transponder chip (the part needed to start the engine). The remote locking/unlocking (RF function) may need a separate learning procedure. Try this manual method:

1. Insert the key and turn to ON.
2. Press and hold the lock button on the remote for 10 seconds.
3. Turn the ignition OFF and remove the key.
4. Test the remote lock/unlock buttons. If that fails, use the X431: go to BSI → Special Function → Learn Remote.

Is it safe to use a second-hand X431?

Yes, but only if the previous owner has properly deactivated the tool from their LAUNCH account. You must register the X431 to your own LAUNCH ID to receive software updates and to purchase IMMO credits. Always ask for proof of deactivation before buying a used tool. If it’s still linked to the old owner, you won’t be able to update or use paid features.

Final Thoughts

Adding a key to a 2016+ Citroën Jumpy or SpaceTourer with a LAUNCH X431 is a straightforward job — if you have the right tools and information. The key points to remember: always check the battery voltage, have the correct PIN handy, use a compatible blank key, and ensure your X431’s IMMO software is up to date.

For DIY owners or small workshops, this procedure can save hundreds of dollars compared to dealership visits. And once you’ve done it a couple of times, you’ll find it’s no more complicated than a routine oil change — just with more lights and beeps.

If you ever get stuck, remember that the LAUNCH X431 community forums and YouTube are excellent resources. And when in doubt, a professional auto locksmith with PSA experience is always a safe fallback.
