Ducati's dealer bulletin puts the 2020 model on the I2K-2 system, where the instrument panel holds the key codes and there is no Code Card. Lose one key and the fix is routine; lose both and the factory answer is a parts order, so it pays to act while one key still works. **Ducati Streetfighter V4 key quick facts** - Ducati's North American immobilizer bulletin lists the 2020 Streetfighter V4 under the I2K-2 system, in the group whose key transponder cannot be removed from the key. - The Streetfighter V4 owner's manual says the motorcycle comes with 2 keys and that both contain the immobilizer system code. - The same key starts the engine, opens the fuel tank plug and opens the seat lock. - The I2K-2 dash stores two keys, no more and no fewer, so a replacement key is programmed together with the one you kept. - The manual has a section on restoring operation with a PIN code, set from the Setting menu on the dash. ## Ducati Streetfighter V4 key types by year | Years | Models | Key type | Chip | Notes | | --- | --- | --- | --- | --- | | 2020 | Streetfighter V4, Streetfighter V4 S | two transponder keys (I2K-2) | yes | Listed by Ducati under I2K-2 with a non-removable transponder. Key codes live in the instrument panel control unit. | | 2023-2024 | Streetfighter V4, Streetfighter V4 S | two transponder keys | yes | The owner's manual describes two immobilizer keys, an antenna built into the ignition switch and a four-digit PIN code. For other years, give us the VIN and we confirm. | ## How the Streetfighter V4 key system works Each key has an electronic device in its grip. When you turn the ignition on, an antenna built into the ignition switch reads it, and the manual explains that the signal acts as a password that changes with every start. The bulletin adds the missing piece: on I2K-2 bikes the instrument panel is the unit that remembers the keys and then tells the engine computer over the CAN line that the start is allowed. Two details follow from that. The dash is paired to the keys, so swapping in a used dash from another bike does not carry your keys with it. And because the transponder on this model is sealed into the key, a cracked key cannot donate its chip to a new shell the way some Monster 821 or SuperSport keys can. **Need a key for your Streetfighter V4?** Call or text with the year and where the bike is parked. Call or text (619) 775-1858. ## Locks the key works Ducati kept the lock count low on this bike. - Ignition switch, which also locks the steering - Fuel tank filler plug - Seat lock, which releases the passenger seat so the seats can be removed ## One key lost Ducati's manual tells owners who need a spare to bring every key they still have, because all keys, new and old, are programmed in the same session and any key that is missing is erased. That is good news if a key was stolen: it will no longer start the bike afterward. The bulletin describes the dealer process as ordering a key, copying the cut from your remaining key, resetting the stored keys with the diagnostic tool and memorizing both again. ## Both keys lost This is the expensive scenario on paper. For I2K-2 bikes with no key at all, Ducati's bulletin calls for a complete switch kit: keys, lock unit and a new instrument panel, followed by key memorization. A stored PIN does not rescue you here, since the PIN only helps when a key can still turn the switch. Before agreeing to that, call us with the year and VIN. On some Ducati models, specialist equipment can register new keys to the dash that is already on the bike, and we will tell you plainly whether your Streetfighter is one we can handle on site. Have photo ID and the registration or title in your name ready, and mention a weak battery, because programming needs steady voltage. A superbike-based naked with no key is awkward to load on a truck, so a visit where it is parked saves real trouble. ## Where to find the key code There is no Code Card on this bike. The recovery code is a four-digit PIN that you choose and store in the dash yourself, and it only exists if you set it. Write it down at home, not on the bike. If you own the smaller Streetfighter V2, tell us the year when you call and we will confirm its key setup separately. ## What to have ready **Have this ready when you call or text** - Year, make and model of the bike - Where the bike is parked - Whether you have any working key, a broken key or a key code - Photo ID and registration or title (we verify ownership before making a key) ## Ducati Streetfighter V4 key FAQ ### Can I add a third key to my Streetfighter V4? No. Ducati's bulletin says the I2K-2 system memorizes two keys and cannot be programmed with one or with more than two. A new key takes the place of the lost one. ### My key is not recognized. Will the PIN get me home? Only if you stored a PIN beforehand. With a PIN on file, the dash asks for it at key-on and lets the engine start. Ducati notes that this does not work if the key is mechanically damaged and cannot turn the switch. ### Does the Streetfighter V4 use the Hands Free fob like a Diavel? No. The owner's manual describes two conventional keys with a chip inside, used in an ignition switch. The Hands Free system belongs to other Ducati families. ### I bought a used Streetfighter V4 with one key. Is that a problem? It runs fine on one key, but you have no backup, and losing the last key is far more costly than adding a second now. Ask the seller whether a PIN was stored, too. ## The immobilizer system on this bike - [Ducati Immobilizer: Red Key, Code Card, PIN and Lost Keys](https://themotorcyclelocksmith.com/san-diego/immobilizer-systems/ducati-immobilizer/): Every keyed Ducati immobilizer reads a transponder in the key and only lets the engine start when the code matches one stored on the bike. ## More Ducati models [748, 916, 996 and 998](https://themotorcyclelocksmith.com/san-diego/makes/ducati/748-916-996-998/), [749 and 999](https://themotorcyclelocksmith.com/san-diego/makes/ducati/749-999/), [848, 1098, 1198 and Streetfighter](https://themotorcyclelocksmith.com/san-diego/makes/ducati/848-1098-1198-streetfighter/), [DesertX](https://themotorcyclelocksmith.com/san-diego/makes/ducati/desertx/), [Diavel and XDiavel](https://themotorcyclelocksmith.com/san-diego/makes/ducati/diavel-xdiavel/), [Hypermotard 698 Mono](https://themotorcyclelocksmith.com/san-diego/makes/ducati/hypermotard-698-mono/), [Hypermotard and Hyperstrada](https://themotorcyclelocksmith.com/san-diego/makes/ducati/hypermotard-hyperstrada/), [Monster 600, 750 and 900](https://themotorcyclelocksmith.com/san-diego/makes/ducati/monster-600-750-900/), [Monster 620, 695, S2R and S4R](https://themotorcyclelocksmith.com/san-diego/makes/ducati/monster-620-695-s2r-s4r/), [Monster 696, 796 and 1100](https://themotorcyclelocksmith.com/san-diego/makes/ducati/monster-696-796-1100/), [Monster 797](https://themotorcyclelocksmith.com/san-diego/makes/ducati/monster-797/), [Monster 821, 1200 and 937](https://themotorcyclelocksmith.com/san-diego/makes/ducati/monster-821-1200-937/), [Multistrada 1200, 1260 and V4](https://themotorcyclelocksmith.com/san-diego/makes/ducati/multistrada-1200-1260-v4/), [Multistrada 620, 1000 DS and 1100](https://themotorcyclelocksmith.com/san-diego/makes/ducati/multistrada-620-1000-1100/), [Multistrada V2 and V2 S](https://themotorcyclelocksmith.com/san-diego/makes/ducati/multistrada-v2/), [Panigale 899, 959, 1199, 1299, V2, V4](https://themotorcyclelocksmith.com/san-diego/makes/ducati/panigale/), [Scrambler 800, Sixty2 and 1100](https://themotorcyclelocksmith.com/san-diego/makes/ducati/scrambler/), [SportClassic and GT 1000](https://themotorcyclelocksmith.com/san-diego/makes/ducati/sportclassic-gt1000/), [ST2, ST3, ST4 and ST4S](https://themotorcyclelocksmith.com/san-diego/makes/ducati/st2-st3-st4/), [SuperSport](https://themotorcyclelocksmith.com/san-diego/makes/ducati/supersport/), [SuperSport 750, 900, 800, 1000 DS](https://themotorcyclelocksmith.com/san-diego/makes/ducati/supersport-750-900-800-1000/), [All Ducati keys](https://themotorcyclelocksmith.com/san-diego/makes/ducati/) ## Services for this bike - [Lost Motorcycle Key, No Spare](https://themotorcyclelocksmith.com/san-diego/services/lost-motorcycle-key/): No key at all?
