Yamaha Vino 50, Vino 125 and C3 Key Replacement

Quick answerYamaha's small retro scooters use a plain cut key with no immobilizer. On the Vino 50 and Vino 125 the seat is opened from the main switch by turning the key back to OPEN, so the ignition is the only lock that guards the under-seat space. The four-stroke Vino 50 adds a rear wheel lock that also shutters the keyhole, and the C3 has a keyhole cover and its own seat lock.

Vino: everything runs through the ignition

The Vino has no seat keyhole. The 2008 Vino 125 manual tells you to put the scooter on its centerstand, insert the key in the main switch and turn it counterclockwise to OPEN, taking care not to push inward, then fold the seat up. The four-stroke Vino 50 works the same way, with a second OPEN position for when the steering is locked.

Under the seat are the storage compartment and the helmet holder, so the helmet is secured by closing the seat on it. The fuel cap on the Vino 125 sits under a lock cover and has match marks to line up when it goes back on. Yamaha reminds owners to take the key out of the main switch when leaving the scooter, because with the key in place anyone can open the seat.

The Vino 50 wheel lock and keyhole cover

The XC50 Vino has an anti-theft feature that confuses new owners. With the steering locked and the key removed, you pull a rear wheel lock lever down and let go. The rear wheel locks and a cover slides across the main switch keyhole. Yamaha's note adds that if the lever will not come down, rotating the rear wheel a little helps it engage.

To undo it you do not go to the ignition. The key goes into a separate rear wheel lock release, is pushed in and turned clockwise. The wheel frees and the keyhole cover opens. People who buy a used Vino with the cover closed often think the ignition has been tampered with or blocked. It has not. It needs the right key in the right place.

C3: a cover on the keyhole and a real seat lock

The boxy C3 takes a different route. Its main switch has a keyhole cover that you open and close by fitting the bow of the key into a receptacle and turning it, so a replacement key needs the right head as well as the right cut. Unlike the Vino, it opens the seat with the key in a seat lock. Under the seat you pull the helmet holder up to hook a helmet on, and the big storage space the C3 is known for sits beneath. The fuel cap is under a lid.

Lost keys on a Vino or C3

A small scooter often has one key and no spare. When it goes missing, we verify ownership with photo ID and the registration or title, cut a key to the scooter, and check every position of the main switch including OPEN, plus the fuel cap. On a Vino 50 we also work the rear wheel lock and confirm the keyhole cover opens and closes. On a C3 we test the seat lock and the keyhole cover. If your key is locked under the seat, that is a routine opening job and does not need the seat forced.

Where to find the key code

These manuals have a key identification number line in the consumer information chapter for the number supplied with the keys. Scooters are often sold on without it, in which case we make the key from the locks.
