Benelli TNT135 Key Replacement

Quick answerThe TNT135 uses a single small cut key. The US owner's manual from SSR Motorsports shows it running the main switch, the steering lock and the locking fuel cap, and it mentions no chip, code card or fob. A lost key is replaced by cutting a new one to the bike's locks, wherever the bike happens to be.

What the SSR manual says about the TNT135 key

Benelli's 135 is a twelve-inch-wheel mini naked, and its US manual is brief. The key section amounts to the main switch positions. On connects the circuits. Off disconnects them. P, for parking, is marked if equipped and leaves the taillight, license plate light and auxiliary lights on while letting you take the key away; the hazard and turn signal lights can also be used in that position. The steering lock position, also marked if equipped, is reached by turning the handle to the left and pressing the key in.

The manual adds a caution not to turn the key toward lock while riding and to press the key in with proper force. That last phrase is worth remembering. The lock needs a firm push, not a hard one.

The captive key in the fuel cap

The tank holds 7.2 litres, so a TNT135 visits the pump often, and the cap is the lock that does the most work. It is a captive design. The key goes in and turns clockwise, the cap lifts, and after refuelling you press the cap down until the key can be removed. Until the cap has latched, the key stays put.

Do not pull at a key that has not been released yet. A small key does not survive much leverage. If the key will not come out, press the cap down squarely and try again before you twist.

Parking a bike you can pick up

A 135 is light enough for two people to lift into a van, so the steering lock is only part of the answer and a chain through the frame to something solid is the rest. The Parking position is useful if you have to leave the bike at the roadside in the dark, but it runs the lights from the battery, so do not leave it there for long.

If a lock has been replaced after a theft attempt, it may no longer share a key with the others. If your bike came with two different keys, that is the likely reason.

No keys left

We verify your photo ID against the registration or title, identify the lock, and cut a key at the bike. Then we try it in the main switch, the steering lock position and the fuel cap. There is no electronic step. If the main switch has been damaged, it can be repaired or replaced, and we will tell you whether the other locks can be brought onto the same key.

Where to find the key code

The US TNT135 manual has no key number page and no key tag is described. Look for a number stamped on the blade or head of an original key and on any paperwork from the selling dealer. If there is none, the key is made from the locks.

Benelli TNT135 key FAQ

Does the Benelli TNT135 have a chip key?

No. The US owner's manual describes a plain cut key and a main switch with a steering lock position, with no immobilizer, code card or fob.

Why will my key not come out of the TNT135 gas cap?

The cap holds the key until it has latched. The manual says to press the cap down until the key can be removed and to take the key out when you hear the lock click.

What is the P position on the TNT135 ignition?

Parking. Where fitted, it keeps the taillight, license plate light and auxiliary lights on with the key removed, for leaving the bike at the roadside.

Does one key work the ignition and fuel cap on a TNT135?

The US manual shows one key for the main switch, the steering lock and the fuel cap. If a lock on your bike was replaced separately it may have its own key, which can usually be sorted out at the same visit.
