Quick answerThe 955 cc Sprint ST and its half-faired sibling, the Sprint RS, come from the years before Triumph fitted immobilisers. The US owner's handbook describes one plain cut key that works the ignition and steering lock, the seat lock and the fuel tank cap. A lost key on one of these is a cutting job done at the bike, with nothing to program.

Triumph Sprint ST 955i and Sprint RS key quick facts

  • The US Sprint ST and Sprint RS owner's handbook (publication 3850906, issue 1, copyright 1999) has no immobiliser section anywhere in it.
  • The handbook says the ignition key is also required to operate the seat lock and the fuel tank cap.
  • Two keys were supplied from the factory with a small tag bearing the key number.
  • The ignition switch has four positions, OFF, ON, LOCK and P, and the key comes out in OFF, LOCK or P.
  • The fuse table lists an alarm circuit, which is for Triumph's accessory alarm and is not a key chip system.

A sport tourer from before the chip key

Triumph printed one handbook for the Sprint ST and Sprint RS. The US edition opens with the usual safety defect notice from Triumph Motorcycles America, and its key page is short: two keys, a number tag, and a note that your dealer can supply a replacement cut from the key number or copy the original. There is no transponder, no immobiliser warning light among the instruments, and no pairing step described anywhere.

That matters when you are comparing quotes. The later Sprint ST 1050 and Sprint GT are different bikes with their own page on this site. On the 955i machines a correctly cut key turns the switch and the engine runs.

What the one key opens

  • Ignition switch and steering lock: turn to OFF, push the key in and fully release it, then rotate to LOCK
  • P position: the steering stays locked and the tail, side and licence plate lights stay on. The handbook warns that leaving it there for long discharges the battery
  • Fuel tank cap: lift the key hole cover, insert the key and turn it clockwise
  • Seat lock on the left side of the bike, at the rear end of the lifting handle: turn the key anti-clockwise while pressing down on the rear of the seat, then lift and slide the seat back
  • Under the seat: the tool kit, strapped into a recess

Habits that protect these locks

The handbook is blunt about the fuel cap. It has to be pushed shut with the key still in it until the lock clicks, and closing the cap without the key inserted will damage the cap, the tank and the lock mechanism. If the cap on a used bike will not click shut with the key in it, stop and have the lock looked at before forcing it.

The seat makes an audible click when it is properly engaged. Triumph tells you to grasp the seat afterward and check that it is secure in the lock.

When no key is left

We ask for photo ID and the registration or title, then make a key to fit the bike's own locks where it is parked. If you still have the key number tag, tell us, since the number gives the cuts directly. The new key is tried in the ignition, the steering lock, the fuel cap and the seat lock before we call it done. If an accessory alarm was fitted at some point and the bike still will not crank with a good key, that is a separate electrical question and we will say so.

Where to find the key code

The key number is on the small tag supplied with the two original keys. The handbook tells owners to note the number and keep the tag and spare key in a safe place away from the motorcycle. Without the tag, a key is made from the locks.

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)

Triumph Sprint ST 955i and Sprint RS key FAQ

Is there a chip in a Sprint ST 955i key?

No. The US handbook for the Sprint ST and Sprint RS describes an ordinary cut key and contains no immobiliser section, so a new key only has to be cut correctly.

Does the Sprint RS use a different key from the Sprint ST?

Triumph covered both in one handbook with a single key description: the ignition key also works the seat lock and the fuel tank cap.

My battery went flat overnight. Could the key position cause that?

Yes, if the switch was left in P. In that position the steering is locked but the tail, side and licence plate lights stay lit, and the handbook warns against leaving it there for long periods.

Can a key be cut from the number on my key tag?

Yes. The handbook says a replacement can be cut from details of the key number, or copied from an original key.
