> CFMOTO's 300 cc singles use a plain cut key. The US 300SS owner's manual shows the same key working the ignition, the handlebar lock, the fuel tank lock under its cover and the seat lock on the left, and it mentions no immobilizer. If you have lost yours, a new key is cut to the bike's locks where it is parked.

**CFMOTO 300SS and 300NK key quick facts**

- The 300SS owner's manual covers the US model CF300-3US.
- In the ignition's off position the engine cannot be started and the vehicle power circuit is disconnected.
- To lock the handlebar you turn it to the left, then turn the key to the lock indicator.
- The fuel tank lock is under a lock cover: open the cover, insert the key and turn to release the lock.
- The seat lock is on the left side of the vehicle and the tool kit is under the seat.
- CFMOTO's US owner's manual for the 300NK shows the same layout: handlebar lock at the ignition, a fuel tank lock under a cover and a seat lock on the left side.

## CFMOTO 300SS and 300NK key types by year

| Years | Models | Key type | Chip | Notes |
| --- | --- | --- | --- | --- |
| US model CF300-3US | 300SS | cut key | no | Ignition with handlebar lock, fuel tank lock under a cover and seat lock, all on one key. No immobilizer in the manual. |
| From around 2022 | 300NK | cut key | no | The US 300NK manual describes the same keyed ignition with handlebar lock, covered fuel tank lock and left-side seat lock, and no immobilizer. Give the model and year so the correct blank and lock parts are used. |

## Faired or naked, the key works the same way

The 300SS is the fully faired sport bike and the 300NK is the upright naked version of the same engine and frame. For locks and keys the owner sees no difference in how they are used. The 300SS manual for the US model describes an ignition switch with a built-in handlebar lock, and its parking instructions are specific: turn the handlebar fully left, lock it with the key, and take the key out.

The manual stops there. It has no section on an anti-theft system, a coded key or a key indicator lamp. On a 300, security is the handlebar lock and whatever chain or disc lock you add.

**Need a key for your 300SS?** Call or text with the year and where the bike is parked. Call or text (619) 775-1858.

## The covered fuel lock and the left-side seat lock

Two more locks share the ignition key.

- Fuel tank lock: the manual has you stop the bike, switch the engine off, open the fuel tank lock cover, then insert the key and turn it to release the lock.
- Seat lock: on the left side of the vehicle. Insert the key and turn to release the seat.
- Under the seat: the tool kit. The manual's battery removal steps also involve taking the seat off.

## First-bike problems

The 300s are often bought as first motorcycles, and three things are worth watching for on a bike like that. One is a used purchase that comes with a single key, which then gets lost. Another is a key bent in the fuel lock by turning it hard. The last is a tip-over that bends the key in the ignition or damages the switch.

None of these needs a dealer computer. They are lock and key jobs, and each is simpler if it is dealt with before a stiff lock becomes a jammed one.

## No key at all

Bring your photo ID and the registration or title. We identify the lock, cut a key to it on site, and check the key in the ignition, the handlebar lock, the fuel tank lock and the seat lock. If one of those was replaced at some point and no longer matches, we tell you and can key it to the others or cut a second key for it.

## Where to find the key code

The 300SS manual does not describe a key number tag or a place to write a key code. Look for a number stamped on an original key or on a tag supplied by the dealer. A key can be made from the locks if there is no number.

## What to have ready

**Have this ready when you call or text**

- Year, make and model of the bike
- Where the bike is parked
- Whether you have any working key, a broken key or a key code
- Photo ID and registration or title (we verify ownership before making a key)

## CFMOTO 300SS and 300NK key FAQ

### Do the CFMOTO 300SS and 300NK use an immobilizer?

The US owner's manuals for the 300SS and 300NK describe a cut key and a handlebar lock and mention no immobilizer.

### Does the same key open the gas cap and the seat on a 300SS?

Yes. The manual shows the key releasing the fuel tank lock under its cover and the seat lock on the left side, as well as working the ignition.

### I dropped my 300NK and now the key is hard to turn. What should I do?

Stop forcing it. A fall with the handlebar lock engaged, or a bent key, can damage the ignition switch. Have the lock and key checked before the key snaps.

### I bought a used 300SS with one key. Is that normal?

It happens on used bikes. Ask the seller whether a spare exists, and either way have a second key cut from your working one now.
