KYMCO X-Town and Downtown 300i Key Replacement

Quick answerKYMCO's 300cc maxi scooters use a cut key with no transponder. Their security is the shutter that closes over the ignition keyhole and reopens only with the matching key. If you have lost the key, a new one can be made to the locks without any programming, but it has to be the right key style to work the shutter.

KYMCO X-Town and Downtown 300i key quick facts

The X-Town 300i manual describes a security shutter closed by a shut button on the ignition panel and opened by inserting the specific key until its notch meets a pin, then turning clockwise.
The Downtown 300i owner's manual has its own Security Shutter section as well as sections on unlocking the seat and the helmet holder.
On the X-Town the seat is released from the ignition switch, with the engine stopped or running.
The X-Town fuel cap is under a filler cover and is unlocked with the ignition key, turned clockwise.
The X-Town manual provides a blank line for the security shutter key code.

Two generations of the same idea

The Downtown 300i was KYMCO's mid-size touring scooter in the earlier 2010s, and the X-Town 300i took over that role afterwards. From a locksmith's point of view they belong together: both manuals describe a conventional key switch guarded by a security shutter, and neither describes an immobilizer. That sets them apart from the bigger AK 550, which has no key at all.

A maxi scooter invites longer trips, and that is where key trouble hurts most. Riding two hours from home on your only key is a risk these scooters make easy to take.

Ignition switch, seat and fuel on the X-Town

KYMCO's X-Town manual puts the main lock functions in one place:

Steering lock: bars all the way left, push the key down, turn to the lock position and remove it
Seat with the engine off: turn the key counterclockwise from OFF to the seat position, then lift the rear of the seat
Seat with the engine running: push the key in and turn it counterclockwise from ON
Fuel: open the filler cover, unlock the cap with the ignition key by turning clockwise, and note the manual's warning not to push the key while refitting the cap
Helmet holders: hooks under the seat that only secure a helmet once the seat is locked

Shutter mistakes and fuel cap habits

A closed shutter can make an X-Town or Downtown owner think the ignition has failed. The plate is meant to be there. Use the shutter end of your key, line up the notch and turn clockwise. If your only remaining key is a plain copy with no shutter end, open the shutter with the original while you still have it and get a proper spare made.

The key-locked fuel cap is the other spot to watch. If the key ever feels rough there, do not force it. A forced key can bend, and a bent key is the start of a broken key.

No keys at all

Let us know if the shutter is closed, because it changes how we reach the lock. After checking photo ID and the registration or title, we make a key to the scooter and confirm it in the ignition, the steering lock, both seat release methods and the fuel cap. Since the seat opens from the ignition, anything locked under it, helmet, documents or tools, is recovered as soon as the new key turns.

Where to find the key code

KYMCO stamps the code on a tab supplied with the keys, and the X-Town manual gives a line headed security shutter key code to record it. The Downtown manual has a page for recording identification numbers. If nothing was written down, a key is made from the locks on the scooter.

KYMCO X-Town and Downtown 300i key FAQ

Does the X-Town 300i have a transponder key?

No. KYMCO's manual describes a cut key and a mechanical security shutter, with no immobilizer or programming.

Is the Downtown 300i key the same idea as the X-Town's?

Yes. Both owner's manuals have a Security Shutter section, so both need a key with the correct shutter end as well as the right cut.

My key works the ignition but not the fuel cap. Why?

The fuel cap is a separate lock, so a worn key or a dirty cap lock can show up there first. A fresh key cut to the lock, and a clean and service of the cap lock, often sorts it out. Do not force it.

Do I need the key code to get a replacement?

It helps if you are ordering from a dealer, but a locksmith can make the key from the scooter's locks without it.
