Key (state number)
A numbered Triumph key (60-0403, formerly D403) for lockable frame fittings like the toolbox, frame lock, or licence holder.
This is a Triumph key, listed in the parts books as 60-0403 (also carried the older D403 designation). It shows up in the catalog sections covering the battery case, toolbox, air filter, and separately in the toolkit, frame lock, and pillion footrest/licence holder listings, which tells you Triumph used this same key pattern across several lockable fittings on the bike rather than just one spot.

Because it's a numbered key, the catalog entry itself says to state the number when ordering - these were cut to match a specific lock, not sold as a generic blank. If you don't have the number stamped on your lock or your old key, we can't just hand you one off the shelf that's guaranteed to work.
The catalog record spans 1960 through 1965 across its several listings, so it was in use for a stretch of those early unit-construction years, but we don't have anything narrowing it to one specific model. Bring in the lock or the old key if you've got it, or call ahead with the stamped number, and we'll get you sorted.
