Vespa P-Series and PX Key Replacement

Quick answerA steel-bodied P-series or PX Vespa has no immobilizer and no chip. Every lock on it is mechanical, so a lost key is a matter of making a new key to the lock or fitting a fresh lock. The catch on older scooters is that the ignition switch and the body locks do not always share a key.

Vespa P-Series and PX key quick facts

The P125X and P200E owner's manual says the steering column security lock, the glove compartment lock and the saddle lock are worked by a single key.
The same manual describes a separate key-operated main switch in the centre of the handlebars, with position 1 for ignition and position 0 for engine off with the key removable.
The later PX owner's manual describes a key switch with LOCK, OFF and ON positions that also locks the steering, and one key for the switch, the seat and the glove box.
Later PX scooters were supplied with one key, one duplicate and a plate showing the identification number to quote for extra copies.

Early scooters: a switch on the headset, locks on the body

On a P125X or P200E the ignition is a small key switch in the middle of the handlebars. Piaggio's manual gives it two jobs: position 1 for ignition and position 0 to cut the engine, where the key comes out. The security side of the scooter is separate. A lock on the steering column holds the bars, another secures the glove compartment flap on the legshield, and a third holds the saddle, and the manual says those three are worked by a single key.

The manual does not say the headset switch uses that same key, and replacement headset ignition switches for US-market P-series scooters are sold with their own pair of keys, so a P200E can have two different keys: one for the ignition switch and one for the body locks. If you bought a P-series with one key, find out which locks it actually turns before assuming the others are seized.

Later PX: one key for everything

Piaggio simplified the arrangement on later PX production. The owner's manual for those scooters describes a key switch with three positions. LOCK is ignition off, key out and steering locked. OFF is ignition off with the steering free. ON is ready to start, with the key held in the switch. To lock the steering you turn the handlebar fully left, turn the key to LOCK and take it out.

The manual says the vehicle is supplied with one key and one duplicate, used for the ignition key switch and for the seat and glove box locks.

Old locks, mixed locks and missing locks

Forty years of use leaves its mark. On a vintage scooter there are three situations to expect:

Worn wafers and worn keys, where the key only works at a certain angle. A key cut to the lock, not copied from the worn one, often cures it
Locks replaced one at a time over the years, so the steering, glove box and seat each take a different key. They can be keyed alike again or replaced as a matched set
A steering column lock stuck in the locked position with no key, which keeps the scooter from being wheeled anywhere until it is opened properly

What a lost-key visit looks like

We ask for photo ID with the title or registration, then work out which locks are original and which key each one takes. A new key is made to the lock where the scooter is parked. If a cylinder is too worn to be worth saving, replacement lock sets for the P-series and PX are still made, and fitting one gives you fresh keys. Tell us whether the steering is locked and whether the scooter has a battery or is kick-start only, so we know what to expect.

Where to find the key code

Later PX scooters came with a plate showing the key's identification number, and Piaggio's manual advises keeping the duplicate key and that code somewhere safe, away from the scooter. Early P-series scooters rarely still have any record of a key number, so the key is normally made from the lock.

Vespa P-Series and PX key FAQ

Does a Vespa P200E have a chip key or immobilizer?

No. The P-series and PX use plain mechanical keys. A correctly cut key is all the scooter needs.

My P200E has two different keys. Is that normal?

It can be. The manual says one key works the steering column lock, glove compartment and saddle, while the main switch on the headset is a separate key-operated part, and replacement switches come with their own keys.

Can all the locks on my PX be made to use one key?

Yes. The later PX was built that way, and on an older or mixed-up scooter the locks can be rekeyed or replaced as a matched set so one key works the switch, the seat and the glove box.

The steering lock is on and I have no key. Can you still help?

Yes. Do not force the bars, which can damage the column. The lock can be opened properly and a key made, or the lock replaced if it is worn out.
