Suzuki Boulevard S40, S83 and Intruder 1400 Key Replacement

Quick answerThese are the oldest designs in Suzuki's cruiser range and their keys are plain metal with no chip. The surprise is the second key. The owner's manuals for the Intruder 1400, sold later as the Boulevard S83, and for the Boulevard S40 both say the bike comes with two pairs of keys, one for the ignition switch and one for the steering lock. If you only have one key shape, you may be missing half the set.

Two pairs of keys on the Intruder 1400 and S83

Most motorcycles hand you two copies of one key. The VS1400 manual describes something different: two pairs. One pair is for the ignition switch. The other pair is for the steering lock, which is a separate lock used with the handlebars turned all the way to the left.

Bikes this age have usually changed hands several times, and a second key that is rarely used is easy to lose along the way. If you have never been handed a steering lock key, the steering lock can still be given one. It is cut to that lock on its own, since the ignition key was never meant to fit it.

The Boulevard S83 is the same motorcycle under its 2005 name, so the same question applies: count your key shapes, not just your keys. To lock the steering, the manual has you turn the bars full left, insert the steering lock key, turn it counterclockwise and push it further in, then turn it back clockwise and pull it out.

What the Intruder 1400 ignition key opens

Suzuki's manual repeats its usual warning here: never ride with a helmet fastened to a holder, and if you must carry a spare helmet, fix it on top of the seat.

Ignition switch. In ON the headlight and taillight come on automatically and the key cannot be removed.
Fuel tank cap: insert the ignition key and turn it clockwise.
Two helmet holders: insert the ignition key and turn it clockwise to open the latch.
Not the steering lock, which has its own pair of keys.

Boulevard S40 and Savage 650

The S40 is the Savage 650 under the name Suzuki gave it for 2005, a 652cc carbureted single with no immobilizer. Its key is a plain cut key, but like the Intruder 1400 it has two of them. The S40 owner's manual says the motorcycle comes equipped with two pairs of keys, one for the ignition switch and the other for the steering lock.

The ignition switch is not up by the handlebars. The manual places it on the left side below the seat, with three positions: OFF, ON and P. In P the key comes out and the front turn signal light and taillight stay lit for parking at the roadside at night. The steering lock is a separate lock that takes the steering lock key, with the bars turned all the way to the left.

Fuel tank cap: ignition key, turned clockwise, then the cap lifts off with the key in it.
Helmet holder: on the right side of the rear fender near the rear turn signal. Ignition key clockwise to open the latch.
Tool box cover: ignition key, turned clockwise to remove the cover.
Steering lock: its own key, not the ignition key.

Old locks and a lost key

With an S40, an S83 or an Intruder 1400, we check your photo ID and the registration or title, cut an ignition key to the bike and test it in the switch, the tank cap and the helmet holder locks. If the steering lock key is missing as well, we make that one separately.

Wear is the other thing to plan for on locks this old. If your key is bent, cracked at the shoulder or needs a wiggle to turn, a fresh key cut to the original depths is cheap insurance against a broken key in the ignition.

Where to find the key code

The Intruder 1400 manual says the ignition keys are stamped with an identifying number and that the steering lock key numbers are on a plate supplied with the keys, and it gives a box to write both in. So there are two numbers to look for, one for each lock.

No. The S83 is the Intruder 1400 under the name Suzuki gave it in 2005, with the same lock layout.

Does the Boulevard S40 have an immobilizer?
