Genuine Stella Key Replacement

Quick answerThe Genuine Stella is a steel-bodied scooter built on the Vespa PX pattern, and its locks follow that pattern too. The key is plain metal with no chip, and Genuine's manual says the same key that starts the scooter also locks the steering column, the glove compartment and the saddle. A lost key is made to the lock, or the locks are replaced as a set.

Genuine Stella key quick facts

The Stella owner's manual says the key that starts the scooter also locks the steering column, glove compartment and saddle.
To lock the steering, the handlebar is turned fully left and the key is turned anti-clockwise to the lock position, then pulled out.
Turning the key clockwise unlocks the steering, and further clockwise reaches ON.
Genuine's parts supplier sells a key blank listed for the Vespa P and PX and the Stella 2T, 4T and Automatic, with a warning to check the slot pattern on your existing key.
Lock and tumbler sets are sold to fit both the PX 150 and the Stella 2T and 4T.

A PX in everything but name

The Stella was made by LML, the Indian company that once built the Vespa PX under licence, and it wears the same pressed-steel body, the same legshield glovebox and the same hinged saddle. For lock work this is helpful. The parts trade treats the Stella and the later PX as one family: the same key blank listing, and lock and tumbler sets advertised for both.

The owner's manual confirms the one-key arrangement. It says the key that starts the scooter also locks the steering column, the glove compartment and the saddle.

How the Stella's key switch works

The ignition switch doubles as the steering lock, and the manual describes its positions in one sweep:

Lock: with the bars turned fully left, turn the key anti-clockwise and withdraw it; the steering is held
Unlocked: insert the key and turn clockwise to free the steering
ON: further clockwise; the tail and position lamps come on and the brake lamp, flashers and horn become live
The manual cautions that leaving the key at ON for more than five minutes with the engine stopped drains the battery noticeably

Two blanks, so look before you buy

The supplier's listing for the Stella blank carries a warning: check the slot pattern on your existing key, because you may need the other part number. In practice there is more than one groove profile in circulation for these scooters, and the wrong blank will not enter the lock at all. A blank bought online by model name alone can easily be the wrong one. If you are ordering a spare yourself, compare the grooves on both faces of your current key with the photo before paying.

A locksmith working from the scooter's lock sidesteps the question, since the lock itself shows which profile it takes.

Lost keys and tired locks

Stellas are enthusiast scooters, and some have had their locks changed during repaints and rebuilds. You may find the glovebox or saddle on a different key from the ignition. When we make a key we check all of them and tell you what matches. If the cylinders are worn or mismatched, a new lock set brings the whole scooter back onto one key.

For an all-keys-lost visit we need photo ID and the title or registration. Tell us if the steering is locked, because a locked Stella cannot be rolled, and whether the scooter is a two-stroke, four-stroke or Automatic.

Where to find the key code

Genuine says it does not cut keys by VIN. For the Stella, it says a four-digit code was either stamped on the keys or on a small metal tag supplied with the scooter, and that a key can be cut from that code. Without the code, Genuine points owners to a new tumbler set. A key can also be made from the lock or copied from an existing key.

Genuine Stella key FAQ

Is there a chip in a Genuine Stella key?

No. It is a plain metal key. The Stella's only theft protection is the steering column lock.

Does one key work the ignition, glovebox and seat on a Stella?

It should. The owner's manual says the same key locks the steering column, glove compartment and saddle. If yours differ, a lock has been replaced at some point.

Can I use a Vespa PX key blank for my Stella?

Often yes. Genuine's parts supplier lists one blank for the Vespa P and PX and the Stella, but warns that the slot pattern must match your existing key, since a second profile exists.

My Stella's locks are all on different keys. Can that be fixed?

Yes. The cylinders can be rekeyed alike, or a matched lock and tumbler set fitted so one key does everything again.
