Honda Ruckus and Metropolitan Key Replacement

Quick answerThe Ruckus and Metropolitan both use a plain cut key with no chip, so a lost key is cut to the scooter on site and works immediately. The Metropolitan adds two things the Ruckus does not have: a theft shutter that closes over the ignition keyhole, and a SEAT position on the ignition switch that releases the seat. Both change what a lockout looks like.

Honda Ruckus and Metropolitan key quick facts

The 2018 US Ruckus and Metropolitan owner's manuals have no immobilizer section; both describe a plain ignition key.
The Metropolitan's ignition switch has a shutter that covers the keyhole, opened and closed with a shutter key that Honda shows alongside the ignition key.
The Metropolitan's seat opens from the ignition switch: turn the key to SEAT and press the seat opener switch.
On the Ruckus, the ignition key also works the fuel fill cap under the fuel tank lid and the helmet holder on the left seat rail.
Both scooters lock the steering at the ignition switch: push the key down and turn to LOCK.

Ruckus: one key, three locks

The Ruckus is about as simple as a keyed vehicle gets. The 2018 US manual shows the ignition key doing three jobs.

Ignition switch: ON, OFF and LOCK. The key comes out in OFF or LOCK, and LOCK locks the steering.
Fuel fill cap: pull the tab to open the fuel tank lid, then use the ignition key in the cap
Helmet holder: on the left seat rail. Turn the key counterclockwise to release it, hang the helmet on the pin and push the pin in to lock

Metropolitan: the shutter and the SEAT position

The Metropolitan's ignition switch is fitted with a shutter, a small sliding cover over the keyhole that Honda tells owners to close after parking for theft prevention. Closing it is easy: the manual notes you can move the knob without the shutter key. Opening it takes the shutter key, whose projection lines up with a slot on the shutter.

That matters when keys go missing. If the shutter is closed and the shutter key is lost along with the ignition key, the keyhole is covered, so tell us whether the shutter is open or closed when you call. It also matters when buying a spare: a plain copy of the blade will run the scooter, but it will not open a closed shutter unless it has the shutter key part as well.

The seat is the other difference. There is no separate seat lock. Honda's manual has you point the handlebar straight ahead, turn the ignition key to SEAT and push the SEAT side of the seat opener switch. The helmet holder is under the seat, and the fuel fill cap, reached through the fuel lid, is opened with the ignition key.

Lockouts, worn keys and forced ignitions

The Metropolitan manual warns you to take care not to lock your key in the compartment under the seat, and it is the classic scooter lockout: key goes in the bucket with the groceries, seat drops, done. With the key inside, the SEAT position on the ignition is no help. This is a lockout we handle on site.

On any scooter that lives outdoors, age and weather work on the locks. A key that needs wiggling is a warning. Have a fresh key cut to the lock before it gets worse, and avoid forcing it, because a snapped key in a 49 cc scooter's ignition still means a locksmith visit.

Light scooters can be a theft target, and a forced ignition is a different job from a lost key. If someone has forced yours, the switch may need repair or replacement before any key will work properly. Tell us what you can see and we will bring what is needed.

All keys lost

We confirm ownership with photo ID and the registration or title, cut a key to the scooter's locks where it is parked, and test it in the ignition and every other lock. There is no programming on either model.

We still need to see paperwork in your name for a 49 cc scooter. If you bought it used with a bill of sale only, have that and your ID ready and call us to talk it through.

Where to find the key code

Ruckus: the manual says to record the key number provided with the original keys. Metropolitan: on the key number plate supplied with the keys. If neither was kept, the number can be recovered from the locks; Honda says a dealer would remove the ignition switch assembly to find it.
