Motorcycle top case locks and keys

The cylinder, the heart of the top case lock

On a motorcycle top case, the cylinder generally controls two functions: it locks the lid and secures the case to its plate, preventing it from being removed from the luggage rack. Depending on the position of the key, you can open the lid, release the case from its support, or lock everything. Exposed to rain, road salt in winter, and dust, the cylinder eventually becomes stiff, turns badly, or gets the key stuck halfway. Replacing it costs much less than a new top case and restores the lock’s reliability, provided you choose a cylinder from the same range as the case, as the fittings can vary between models.

The other accessories

Top case accessories also come in various options:

• Backrests.
• Miscellaneous.

All accessories are gathered on the accessories page.

A single key for top case and panniers

Luggage manufacturers offer identical cylinder sets, supplied with the same keys, to be fitted on the top case and side panniers. You can then open all your luggage with just one key, instead of rummaging through a bunch of keys at each stop. Some motorcycle makers go even further with original panniers that open with the ignition key. To harmonise existing equipment, you count the number of locks, usually one per pannier, and order a complete set from the same series. Replacing it is done with the lid open, using the original key to pull out the old cylinder, following the luggage instructions.

Spare key and lock maintenance

The number engraved on the key, or on a tag provided with it, allows you to order a spare: write it down when you make your purchase, and keep the spare key at home rather than in your bag. Without a number or a spare, you’ll need to change the entire cylinder. For maintenance, a dry lubricant such as graphite or PTFE, sprayed into the keyhole once or twice a year, prevents sticking without trapping dust like greasy oil. After a high-pressure wash, operate the lock several times to expel water, especially before a freezing night that could jam the mechanism.

Good deals

Good deals can also be found in good plans, promotions, clearance, sales, and Black Friday. The new arrivals showcase the latest collections, and items shipped within 24 hours are prepared and dispatched in 24 hours. The key events of the year follow a steady schedule: Black Friday at the end of autumn, the year-end holidays, the winter sales, the French Days in spring, then the summer sales and back-to-school season.

Frequently Asked Questions

Can a top case key be copied by a locksmith?

Often, if the locksmith has the corresponding blank, but motorcycle luggage keys can sometimes be specific. The safest option is still to order a spare from the manufacturer using the number engraved on the key or its tag.

How to open a top case if the key is broken in the lock?

If a piece is sticking out, grab it with fine pliers and pull without turning. If it’s inside, a locksmith can extract it; take the opportunity to replace the cylinder if the lock has been damaged during the process.

Why does my top case key turn in vain?

Most often, the part connecting the cylinder to the locking mechanism is broken or detached. Remove the inner cover to check it; if the cylinder itself is at fault, replacing it will solve the problem.

Is a locked top case enough to prevent theft?

It discourages opportunistic theft but doesn't resist well against tools: do not leave papers or valuables in it during a long stop. Park the motorcycle in sight and, for the night, remove the top case or take its contents to your hotel.

Why does my key struggle to insert?

First, inspect the key: a bent or worn tooth is enough to block the entry. If it is intact, blow dust out of the lock then apply a dry lubricant; if nothing changes, the cylinder is worn and needs to be replaced.
