Quick answerThe Trident 660 has an electronic immobiliser that is paired to both the engine ECM and the transponder chip in the ignition key. Triumph's service information says the bike is delivered with two keys and the system holds a maximum of four. A copied blade without a paired chip will not start it, so replacing a lost key is a cut-and-program job.

How the 660 immobiliser is put together

Triumph's service information for the Trident describes three parts that have to agree before the engine will start. The first is the transponder chip inside the ignition key. The second is the antenna coil at the ignition switch, which wakes the chip when the key is turned to ON. The third is the immobiliser control module, which talks to both the chip and the engine ECM and only allows a start when it receives a matching signal.

The system has to be paired with the engine ECM and with each key. That pairing is why a used ECM, a used immobiliser module or a key from another Trident does nothing on your bike until it has been set up for it.

Two keys supplied, four at most

The Trident leaves the factory with two keys. Triumph says keys can be added to or deleted from the immobiliser system, up to a maximum of four. Two things follow from that. If you bought the bike used with a single key, there is room to add a spare without any parts being replaced. And if a key was lost or stolen with the bike's paperwork, it can be deleted from the system so it no longer starts the engine, although its blade would still turn the locks.

Looking after a transponder key

The service information includes handling advice that explains most intermittent no-starts on a healthy bike.

  • Do not keep another transponder key next to the one in the ignition; a second chip close by can upset the reading
  • Keep magnets and magnetic items off the key ring
  • Do not submerge the key in water or any other fluid
  • Do not drop the key or strike it against hard material; the chip is inside the plastic head

Replacing a lost Trident 660 or Tiger Sport 660 key

With one working key, a spare is straightforward: a blade is cut to match and the new transponder key is added to the immobiliser, then both keys are tested. Triumph's parts catalog lists the same cut immobiliser key for the Trident 660, Tiger Sport 660, Daytona 660 and Tiger Sport 800, so the four share a key family.

With both keys gone, the blade is cut to the bike's locks and a new key is programmed to the immobiliser at the bike. Whether that can be done to the existing module depends on the bike, so call with the VIN and year first. You will need photo ID and the registration or title in your name, and the bike needs a charged battery so the voltage stays steady during programming.

Triumph Trident 660 and Tiger Sport 660 key FAQ

How many keys can a Trident 660 have?

Four. Triumph's service information says the bike is supplied with two keys and a maximum of four can be added to the immobiliser system.

Can a lost Trident key be blocked?

Yes. Triumph says keys can be deleted from the immobiliser system as well as added, so a missing key can be removed and will no longer start the engine.

Do the Trident 660 and Tiger Sport 660 use the same key?

Triumph's US parts catalog lists one cut immobiliser key part for both, along with the Daytona 660 and Tiger Sport 800. Each key is still cut and paired to its own bike.

Will a plain copy of my Trident key work?

It will turn the locks but not start the engine. The immobiliser needs a matching signal from the transponder chip inside a paired key.
