Genuine Roughhouse and Rattler Key Replacement

Quick answerThe Roughhouse 50 and the Rattler family use plain cut keys with no chip. On the Roughhouse and the earlier Rattler 50 the seat lock is on the left rear body panel and the fuel cap has its own keyhole.

Three places the key goes on a Roughhouse

Most Genuine scooters put everything through the ignition. The Roughhouse 50 and the earlier Rattler 50 spread the work across three keyholes. The ignition gives you ON, OFF and LOCK, with LOCK holding the bars at the left stop. The seat has its own keyhole on the left rear body panel, turned clockwise to release the latch. And the fuel filler is outside the bodywork, not under the seat, behind a little keyhole cover you press to the right to expose a third keyhole.

The fuel cap has a behaviour worth knowing. Genuine's manual says the key stays captured in the cap from the moment you remove it until it is pressed back on, clicked down and locked. You cannot ride off with the cap in your pocket, and you cannot take the key back until the cap is properly seated.

The newer Rattler's ignition cover

The Rattler 125 and Rattler 200i are a later design. Their manuals list ON, OFF and LOCK plus a fourth point on the switch: an anti-theft ignition cover. The fob on the key has a hexagonal portion, and inserting it at that point and turning left operates the cover. The seat on these scooters opens from the ignition, by pressing the key in from OFF and turning.

So an owner moving from a Roughhouse to a Rattler 200i goes from three keyholes to one, and gains a cover that needs the original fob.

Things to check before you call

A key that seems stuck in the fuel cap, when the cap simply has not been clicked down and locked
A stiff fuel cap or seat lock on a scooter stored outdoors, which can happen to any exposed lock
A Rattler 125 or 200i with a plain copied key that cannot work the ignition cover

Lost key visit

Tell us which scooter and roughly what year, because the two generations need different blanks and checks. After confirming ownership with photo ID and the registration or title, or moped paperwork for a 50, we make a key to the lock. On a Roughhouse we then try it in all three keyholes. If one of them has been replaced in the past and no longer matches, we can tell you on the spot and put it right.

Lock the steering whenever you park, and add a chain if the scooter lives outside.

Where to find the key code

Genuine says it does not cut keys by VIN and these manuals do not describe a key code tag. Check the original keys and paperwork for a stamped number. Otherwise a key is made from the locks on the scooter.

Genuine Roughhouse and Rattler key FAQ

Does a Roughhouse 50 use the same key as a Buddy?

No. Genuine's parts supplier lists a different blank, shared with the Rattler 50 and 110 and the Black Cat 50.

My key won't come out of the Roughhouse fuel cap. Is it jammed?

Probably not. The key is held in the cap until the cap is back on the filler, pressed down until it clicks and turned to lock. Then it releases.

Where is the seat lock on a Roughhouse 50?

On the left rear body panel. Insert the key and turn clockwise, and the seat comes off its latch.

What is the hexagonal part on my Rattler 200i key fob for?

It operates the anti-theft cover over the ignition. Insert it at the marked point on the switch and turn left.
