Lost Motorcycle Master Key, Code Card or Key Tag: What Changes

Quick answerA master key, code card or master PIN is the item the maker uses to authorize new keys for your bike. Losing it usually does not stop you riding today, because your everyday keys still start the engine. What changes is the future: adding a spare gets harder, and on some makes the owner's manual says parts of the immobilizer must be replaced if the everyday keys are lost as well. Only bikes with an immobilizer or a keyless system have one of these items.

What each item is, on bikes that have one

Makers use different objects for the same purpose. Some give you a colored key that manages the others, some give you a card or tag, and some give you a PIN. A plain-key bike, which covers many Japanese motorcycles sold in the US, has none of these: its key number tag only records how the key is cut, and our key code guide covers that. Systems changed over the years, so check the keys section of your own manual.

Bikes	Item	What it does	If it is lost
Yamaha with the immobilizer, mostly export-market bikes and imports	Red code re-registering key	Registers codes in the two black standard keys	Black keys still start the bike, but the manual says registering a new standard key is impossible
Ducati with the red key system, to about 2010	Red key plus Code Card	The red key is the master and the only key that can add or delete black keys	Black keys still start the bike; adding keys becomes a major job
Ducati with two black keys and a card, about 2007 to 2015	Code Card	Allows keys to be deleted and reprogrammed	Ducati does not sell a replacement card by itself
Later Ducatis, keyed and Hands Free	No card; a four-digit PIN the owner stores	Can release the engine start if a key is not recognized	Nothing to lose, but no fallback if you never stored one
Larger KTM twins with the orange key	Orange programming key and KEYCODECARD	The orange key activates and deactivates black ignition keys; the card carries the key number	No owner route to activate a new black key or switch off a lost one
KTM 390, 690, 790 and 890 models; Husqvarna 401, 701, 801 and Norden 901	KEYCODECARD	Carries the key number for ordering a spare; these bikes have no immobilizer	A key is made from the lock or an existing key instead
Vespa and Piaggio with the immobilizer	Master key, with a red grip on older models and a brown grip on later ones	Needed to store new keys in the scooter's control unit	Everyday keys still work; the manuals warn that later immobilizer repairs are affected
Vespa GTS with Piaggio Keyless	A single TAG supplied with the remote	Takes the place of the master key	The manual says the keyless components have to be replaced
Honda with HISS: the Valkyrie Rune and bikes from other markets	Key tag with key number and bar code	Taken to the dealer with a key and the bike to register a duplicate	With every key lost as well, the manual says the control unit must be replaced
Honda Smart Key models	ID tag and emergency key	The manual says both are needed to register a new Smart Key at the dealer	No simple route to a new fob
Yamaha smart key models	Smart key emergency code card	The code that lets you operate the bike without the fob	With the fob lost too, Yamaha says the entire smart key system is replaced
Indian with a key fob	Master PIN supplied by the dealer	Sits behind the rider PIN you set yourself	If both PINs are lost, only an Indian dealer can retrieve it

Colored keys: red, orange and brown

Yamaha's manuals call the red-bow key the code re-registering key. It exists to register codes in the standard keys, and Yamaha says to store it in a safe place and not use it for riding. US-market Yamahas rarely have this system, so a red key in the set usually means an export-market or imported bike.

On older Ducatis the red key is the master. Chipped keys and a Code Card appear in Ducati manuals from before 2006, and the red key arrangement ran to about 2010. On Hands Free Ducatis such as the Diavel, a red key means something different: it is the passive key, a backup with a transponder for when the battery-powered active key is not working or not available.

KTM's orange key is a programming key for the black ignition keys on the larger twins, and the manual says the ignition is only meant to be switched on with a black key. On Piaggio and Vespa scooters the master key has a red grip in older manuals and a brown grip in later ones, which is why owners call it either the red key or the brown key. Everyday keys are blue or black depending on the model.

Cards, tags and PINs

Ducati's Code Card is a credit-card-size card supplied with the keys on the older systems, and the manuals say to hand it to the new owner with all the keys when the bike is sold. Later Ducatis have no card. The owner stores a four-digit PIN instead, and Ducati is clear that it only helps if it was set up beforehand.

Honda's Smart Key bikes come with an ID tag carrying an ID number. Honda says to carry the tag separately from the fob and keep a copy of the number somewhere other than the vehicle. Yamaha's smart key models come with one fob and a card printed with the smart key emergency code, and Yamaha says it keeps no record of that code.

KTM and Husqvarna print the key number on the KEYCODECARD and say you need it to order a spare key. On their models without an immobilizer the card is a convenience, not a security item. Indian's keyed Scout and FTR models carry the key number on a metal tag on the key ring, and its fob models rely on the rider PIN and the dealer's master PIN.

What losing it changes

Specialist equipment can sometimes program new keys to the existing control unit without the master key or card, depending on the make, model and year. Ask about your exact bike before you buy parts.

Riding today: usually nothing. Everyday keys keep working on every system above.
Adding a spare: harder. The factory route often needs the master key, card or tag, as our guide to adding a spare chip key explains.
Losing everything: the expensive case. Yamaha's manual says the entire immobilizer system must be replaced, Honda's says the control unit on a HISS bike, and Suzuki's says the ECM on its immobilizer equipped models.
Selling the bike: a buyer who knows the system will ask for the master key or card, and Ducati expects them to go to the next owner.

What to do now

If you have lost the master key or card but still have a working key, get a spare made now. One working key is what keeps the job a routine key programming visit, and it is the cheapest point at which to act. Photograph any key number, code card or tag you do have and store the picture and the original away from the bike, with the title.

If you bought the bike used and never received these items, ask the seller once more, then tell whoever makes your next key. We ask for photo ID and the registration or title before any key work, and it helps to bring every key you have, including broken ones.

Quick questions

I lost my Yamaha red key. Can I still ride?

Yes. Yamaha's manual says the vehicle can still be started with the standard keys, but a new standard key cannot be registered without the red one. Contact a dealer or a locksmith who works on Yamaha immobilizers before you lose a black key as well.

Is the Vespa master key red or brown?

Both exist. Older Piaggio manuals describe a master key with a red grip and later ones a brown grip. Either way it is needed to store new keys, so keep it at home and ride with an everyday key.

Do BMW motorcycles have a code card?

No. BMW's rider's manuals say extra keys come only through an authorised BMW Motorrad dealer, who must check the legitimacy of the request, so your registration or title is the document that matters.

Can I ride with the red or orange key every day?

The manuals say not to. Yamaha tells owners to store the red key in a safe place, and KTM says the ignition should only be switched on with a black key. If the master is on your keyring, one loss takes everything.

My KTM 390 or 790 came with no orange key. Is one missing?

No. KTM's 390, 690, 790 and 890 models use a conventional key with a KEYCODECARD and have no immobilizer, so there is no programming key. The orange key belongs to the larger twins.
