Suzuki GSX-R600 and GSX-R750 Key Replacement

Quick answerThe GSX-R600 and GSX-R750 share a chassis and one owner's manual, so they share a key and lock layout too. The US edition of that manual describes two ordinary keys and has no immobilizer section, which makes a lost key a cutting job done where the bike is parked. Bikes built for other markets can carry a chip key, so tell us if yours was imported.

Suzuki GSX-R600 and GSX-R750 key quick facts

Suzuki's owner's manual for the current GSX-R600 also covers the GSX-R750, and its key page says only that two keys come with the motorcycle.
The ignition switch pages of that manual list OFF, ON, LOCK and P and never mention an immobilizer.
The rear seat lock is under the left frame cover and takes the ignition key, turned clockwise.
The helmet holders are underneath the rear seat, so they are reached through that same lock.
The front seat has no lock of its own. It is fastened with bolts under the side frame covers.
Suzuki warns that key chains can catch between the steering damper and the steering stem nut on this bike.

Later years	GSX-R600, GSX-R750 sold new in the US	mechanical cut key	varies	The US owner's manual for the current generation has no immobilizer section. Versions built for other markets can have a transponder key, so check for a key-shaped light on the dash of an import.

One manual, one key layout for both bikes

Suzuki covers the current 600 and 750 with one owner's manual. For a locksmith that matters more than the engine size: the ignition switch, tank cap and rear seat lock are described once for both bikes, in the same places, and a key for one is made the same way as for the other.

The manual's key page is two lines long. It says two keys come with the motorcycle and to keep the spare somewhere safe. There is no chip key section, no immobilizer indicator in the instrument pages and no instruction to visit a dealer for a coded spare. On a GSX-R600 or GSX-R750 like that, the cut of the blade is the whole key.

Where each lock is

Ignition switch with four positions. For LOCK, turn the bars fully left, push the key down and turn. Suzuki adds that if it will not turn easily, ease the bars slightly to the right while turning the key.
P position: locks the steering like LOCK and leaves the taillight on for roadside parking at night.
Fuel tank cap: the ignition key turns clockwise, and you lift the cap with the key still in it. To close, push the cap down firmly with the key in the lock.
Rear seat: lock under the left frame cover, key clockwise, then raise the front of the seat and slide it forward.
Helmet holders: underneath the rear seat. Hook the helmet strap ring on and lock the seat over it.
Front seat: bolted, reached after the side frame covers come off. No key involved.

What tends to go wrong

Suzuki's warning about key chains is specific to bikes with a steering damper. A fob or a bunch of keys can get trapped between the damper and the steering stem nut, so the manual tells you to ride with the bare ignition key. A bare key is easy to misplace, which is a good reason to have a spare cut while you still have one to copy.

The rear seat lock is tucked under the left frame cover, out of sight. If the key is getting hard to turn there, have it looked at before it stops turning, because the helmet holders are behind it. Track bikes are a separate case: if the ignition switch has been removed or replaced with a toggle, tell us what is still fitted so we bring the right parts.

If every key is gone

We start with your photo ID and the registration or title. On a US-market bike we then cut a new key to the locks on the motorcycle and prove it in the ignition, the steering lock, the tank cap and the rear seat lock before we leave. No control unit is involved and nothing has to be ordered from a dealer.

If the dash shows a key-shaped indicator at switch-on, the bike is one of the immobilizer equipped versions and a cut key alone will not start it. Say so when you call and we will tell you whether that version can be handled on site.

Where to find the key code

Suzuki supplies a key number with new keys on a small plate or tag. The key page of the current GSX-R600 and GSX-R750 manual has no box for it, so the number is easy to lose track of. Check the manual pouch and the paperwork from the selling dealer. Without the number, a key can still be cut to the locks on the bike.

Suzuki GSX-R600 and GSX-R750 key FAQ

Is a GSX-R750 key the same type as a GSX-R600 key?

Yes. Suzuki covers both models in one owner's manual with one key section, and the locks are in the same places on both.

Does my US GSX-R600 have a chip in the key?

The US owner's manual for the current bike describes two ordinary keys and has no immobilizer section. If your dash has no key-shaped indicator at switch-on, a cut key is all it needs.

Where is the seat lock on a GSX-R600?

Under the left frame cover. The ignition key turns clockwise, then the rear seat lifts at the front and slides forward. The front seat is bolted on.

Why does Suzuki say not to use a key ring on a GSX-R?

The manual warns that some key chains could catch between the steering damper and the steering stem nut and interfere with steering. It advises using the ignition key with nothing attached.

My GSX-R is a track bike with no ignition switch. Can you still make a key?

If the tank cap or seat lock is still on the bike, usually yes, since those take the same key. Tell us which locks are fitted and whether the original switch is still with the bike.

The immobilizer system on this bike

Suzuki Immobilizer (SAIS): Chip Keys, Lost Keys and US ModelsSuzuki's immobilizer, which Suzuki calls the Suzuki Advanced Immobilizer System, stores an identification code in the key and will not let the engine start without it.
