Triumph America and Speedmaster (865) Key Replacement

Quick answerThe air-cooled America and Speedmaster cruisers use a plain ignition key with no chip, in a switch tucked behind the left side cover, and a different key for the steering lock. The fuel cap twists off without a key and the seat comes off with an Allen key, so the ignition and the steering lock are the only two keyed locks the handbook describes. A lost ignition key is replaced by cutting alone.

Triumph America and Speedmaster (865) key quick facts

The America and Speedmaster handbook says the ignition key operates the ignition switch only; a different key operates the steering lock.
The ignition switch is on the left side of the motorcycle, at the rear of the side cover.
The fuel tank cap is a twist-off cap with a ratchet that stops over-tightening. It has no key lock.
The seat is held by a fastener undone with an Allen key that Triumph stores inside the fuse box cover.
Two ignition keys, two steering lock keys, a number tag for each pair and a spare key blade for the accessory alarm were supplied new.

Where the ignition is, and how the switch works

First-time riders of these cruisers hunt for the ignition around the headlight and find nothing. Triumph mounted it low on the left, at the rear edge of the side cover, cruiser style. The handbook calls it a three-position switch. Clockwise from OFF is ON. To reach PARK you push the barrel further into the lock and keep turning clockwise, which leaves the position lights on with the engine off. The key can be pulled in OFF or PARK.

A switch mounted low on the side of the bike is more exposed to road dirt than one up on the yoke. If the key needs wiggling, have the key and switch looked at together, since a fresh key cut to the original depths often cures what feels like a failing switch.

A separate key for the steering lock

The steering lock sits behind its own cover and takes its own key, supplied as a pair with a separate number tag. It is a two-position lock: push the whole lock in while turning anti-clockwise with the bars swung left to set it, and turn further anti-clockwise with the weight off to let it spring back out. Triumph's handbook for the America LT repeats the same split between ignition key and steering lock key.

Because the two keys are easy to confuse on a ring, look at which lock each one actually enters before deciding a key is worn out.

What is not locked by a key

Two things that take a key on most motorcycles do not on these. The fuel cap simply unscrews anti-clockwise and clicks on a ratchet when tightened, so losing your key never strands you at a pump with a sealed tank. The seat is released by removing a fixing at the rear with the Allen key kept inside the fuse box cover, then pulling a lock release. The handbook lives under that seat.

The practical upshot: with every key gone you can still reach under the seat and fill the tank. You just cannot switch the bike on, or free the steering if it was locked.

Replacing lost America or Speedmaster keys

We ask for photo ID and the registration or title, then cut the ignition key at the bike from the tag number or from the switch. No transponder is involved, so the new key starts the engine as soon as it turns. If the steering lock key is missing as well, say so on the phone and we make both in the same visit. Luggage added to the bike may have locks of its own on other keys; bring whatever keys you have for those.

Where to find the key code

Each pair of keys came with its own small tag: one number for the ignition keys, another for the steering lock keys. The handbook tells owners to record both and store the tags with the spares, away from the motorcycle, and says a Triumph dealer can cut a key from the number or use an original as a master.

Triumph America and Speedmaster (865) key FAQ

Does the Triumph America have an immobiliser?

The handbook for the air-cooled America and Speedmaster describes a plain ignition key with no transponder. An alarm was a Triumph accessory, which is what the spare key blade in the key pack is for.

I have an 865 Speedmaster. Is its key the same as the new Speedmaster's?

No. The current Bonneville Speedmaster is a liquid-cooled 1200 with a transponder key. The air-cooled Speedmaster uses a plain cut key and a separate steering lock key.

I lost my key at a gas station. Can I still fill up my America?

Yes. The fuel cap on these bikes twists off by hand; it is not keyed. You will still need a new ignition key to ride away.

Where is the key code on a Triumph Speedmaster?

On the small tags supplied with the keys, one for the ignition pair and one for the steering lock pair. If they are gone, the keys are made from the locks.
