Suzuki Bandit 600, 1200, 1250 and GSX1250FA Key Replacement

Quick answerBandits are straightforward bikes and so are their keys. The carbureted Bandit 600 and Bandit 1200 use a plain cut key. The fuel-injected Bandit 1250 manual describes a main key, a spare and a key number plate, and the GSX1250FA manual heads its key section for the Canada and Australia versions, so check an imported bike for an immobilizer indicator.

Carbureted Bandits: an old-fashioned key

The Bandit 600 and the Bandit 1200 come from the years when a Suzuki key was a piece of cut metal and nothing else. There is no electronic check between key and bike. If the blade matches the wafers in the lock, the switch turns and the engine starts.

Age is the thing to watch on these. If a Bandit has spent decades on one key, the blade and the ignition switch can both be worn, and a copy of a worn key carries the wear with it. Cutting a new key back to the proper depths, by number or from the lock, gives a better result than copying wear.

Bandit 1250 and GSX1250FA

Suzuki's manual for the liquid-cooled GSF1250 and GSF1250S says the motorcycle comes with a main ignition key and a spare. It adds that the key number is stamped on a plate provided with the keys, that the number is used when ordering replacements, and it leaves a box for you to write it down.

The faired GSX1250FA shares the Bandit 1250's engine. Its manual prints a key section headed for the Canada and Australia versions that describes the same main key and spare with no immobilizer wording. Because that heading is market-specific, do not assume an imported bike matches it: look for an immobilizer indicator on the dash at switch-on and tell us what you see.

The seat lock guards the helmet holders

Both manuals describe the same arrangement at the back. The ignition key goes into the seat lock and turns clockwise to release the seat. Underneath are the helmet holders. To use one you take the seat off, hook the helmet's fastener ring onto the holder and put the seat back, so the helmet is held by the seat lock.

Suzuki warns against riding with a helmet hanging there and says a helmet that must be carried should be fixed on top of the seat. From a lock point of view the lesson is that a failed seat lock also traps whatever is on the holders. The fuel tank cap is the third lock on the same key: the Bandit 1250 manual has you insert the ignition key and turn it clockwise.

Replacing a lost Bandit key

We ask for photo ID and the registration or title, then cut a key to the motorcycle. On a carbureted Bandit or a plain-key 1250 that is the full job, finished once the key has been tried in the ignition, the steering lock, the tank cap and the seat lock.

If the ignition switch is too worn to hold a new key reliably, we will show you and talk through repair or replacement before doing anything further. On an immobilizer version of the 1250, we confirm before the visit whether a key can be registered on site.

Where to find the key code

The Bandit 1250 manual says the key number is stamped on a plate provided with the keys and is used when ordering replacement keys, with a box in the manual to record it. On older Bandits, look for the same small plate with the spare key or the original paperwork.

Suzuki Bandit 600, 1200, 1250 and GSX1250FA key FAQ

Does a Bandit 1200 key have a chip?

No. The carbureted Bandit 1200 uses a plain cut key with no immobilizer.

Is the GSX1250FA key the same as a Bandit 1250 key?

It is the same kind of key on the same platform. Both manuals describe a main ignition key and a spare, and the same seat lock and helmet holder arrangement.

My Bandit key only works if I jiggle it. New key or new ignition?

Often a properly cut new key fixes it, because copies of worn keys carry the wear with them. If the switch itself is worn out, we can repair or replace it and match it to your other locks where the parts allow.

How do I lock a helmet to a Bandit 1250?

The helmet holders are under the seat. Remove the seat with the ignition key, hook the helmet's fastener ring onto a holder and refit the seat.
