Vespa LX and S Key Replacement

Quick answerThe Vespa LX came with two keys: a brown-grip master and a black key for everyday use, plus a code card. The owner's manual allows up to three keys to be programmed, and the brown key is needed to do it the standard way. The Vespa S shares the LX platform. If your only key is lost or the master is gone, tell us which keys remain.

Vespa LX and S key quick facts

The LX 125 and 150 owner's manual describes a key with a brown grip and a black key, each supplied as a single copy.
The black key is for normal use: start-up, seat opening and glovebox opening.
A code card came with the scooter, bearing the same code imprinted on the two keys.
The LX manual allows up to three keys to be programmed, and all keys must be programmed together.
With the switch in LOCK the steering is locked and the front glovebox is locked; in OFF the glovebox is unlocked.

The two keys that came with an LX

Piaggio supplied the LX with one key of each type. The brown-grip key is the master. The manual recommends it be used only under exceptional circumstances, because it is needed to program the others. The black key is the one for daily riding, and on the LX it does three jobs: it starts the engine, opens the seat and opens the glovebox.

Because only one black key was supplied, a lot of LX and S scooters have been ridden on a single key for years, and many have changed hands without the brown key or the code card. If that describes yours, you are one lost key away from an all-keys-lost job.

Adding a key and the three-key limit

The LX manual says programming, up to a maximum of three keys, must be performed on all the keys, both new ones and those you already have. You take the brown key and all the black keys to a Piaggio service centre, and anything left at home is erased from memory. So a spare is simple when the brown key is present, and a different kind of job when it is not.

The ignition switch on the LX also controls the steering lock and the front glovebox. In LOCK the ignition is disabled, the steering lock is engaged and the glovebox is locked. In OFF the steering is free and the glovebox is unlocked. The seat opens with the same black key. Since one key and one main lock do so much on this scooter, a bent key or a worn ignition tends to show up everywhere at once: the key gets hard to turn, the glovebox will not release, or the seat will not open.

These are also older scooters now. Keys that have been copied from copies can drift far enough from the original cut to wear the lock. Where possible we cut a fresh key to the lock itself or to the code, not to a worn duplicate.

Lost key visit for an LX or S

We come to the scooter and check photo ID and registration or title. With the brown key and code card in hand, a new black key is quick. Without the brown key, or with no keys, the common route is to cut and supply a new master and everyday key for the scooter's existing control unit. Tell us the year and whether your LX is carbureted or fuel injected, because that changes how the job is done.

Where to find the key code

The LX was delivered with a code card bearing the same code imprinted on the two keys. Look in the manual pouch, the glovebox and the original dealer paperwork. If the card is missing, the blade can be made from the black key or from the lock.

Vespa LX and S key FAQ

Which Vespa LX key is the master?

The key with the brown grip. The owner's manual says it should be used only under exceptional circumstances, and it is the key a service centre needs in order to program others.

Does the same key open the LX seat and glovebox?

Yes. The manual lists start-up, seat opening and glovebox opening as the jobs of the black key, and the glovebox also locks when the ignition is turned to LOCK.

Can I have more than two keys for my LX?

The manual allows up to three programmed keys. They are stored together, so every key you want to keep has to be present.

Is the Vespa S different from the LX?

The S is built on the LX platform and uses the same Piaggio master key arrangement. Check your own key set for the grip colours, and tell us the model and year when you call.
