MV Agusta F4 750 and Brutale 750 Key Replacement

Quick answerThe first modern MVs, the F4 750 and the Brutale 750 S, use a single cut key for the ignition and all the locks. Their owner's manuals describe a key supplied in duplicate and a key identification number to write down, and they contain no immobilizer mode and no MV Code Card. The practical challenge with these bikes is not electronics. It is finding someone with the right blank who will come to a rare bike and cut the key properly.

MV Agusta F4 750 and Brutale 750 key quick facts

The F4 750 S and S 1+1 manual states that a key is supplied in duplicate for both the ignition and all the locks.
The 2004 Brutale S manual says it is essential to provide the key identification number when ordering a spare key, and gives a KEY No. field to record it.
The 2004 F4 750 SR handbook, which was also printed in a USA edition, has no immobilizer section and no Code Card.
On the F4, the same key opens the fuel tank cap and the lock that releases the tail section over the glove compartment.
The ignition switch has four positions: OFF, ON, LOCK and P for parking with the steering locked.

What MV's early manuals say

MV Agusta's wording barely changed across the 750 range. A key is supplied in duplicate for the ignition and all the locks, keep the duplicate in a safe place, and write the key identification number in the space provided. That is the whole key chapter. The dash on these bikes has a clock and trip functions, but nothing called immobilizer mode, which is the screen later MVs use for entering a Code Card number.

So if you own an F4 750 or a Brutale S and have been told to hunt for a Code Card, there may be nothing to find. The piece of information that matters on your bike is the key number.

Locks on the F4 750 and Brutale S

Ignition switch and steering lock: turn the bars, press the key in gently and rotate to LOCK; a further position, P, leaves the parking lights on with the steering locked
F4 fuel tank cap: lift the dust cover, insert the key and turn clockwise to lift the cap; press the cap down while turning the key clockwise to latch it again
F4 glove compartment: with the key turned clockwise in its lock, the rear of the tail section is pressed down, then lifted and folded up over the tank
Brutale S glove compartment: insert the key, press down on the pillion while turning clockwise, then lift the pillion

Things to know before the key goes missing

MV's manuals warn against hanging a ring or other objects from the ignition key because they can hinder the steering. Take that seriously on an F4 with its tight steering lock, and remember that a heavy key ring also wears the ignition.

The P position is another small trap. The manual cautions against leaving the key there for long, since the parking lights drain the battery. A flat battery on a bike that is then assumed to have a key fault is a call we would rather you did not have to make.

Replacing a lost key on a 750

MV's manuals say the key identification number is needed to order a spare key. If you have the number, keep it safe; if not, a locksmith can make the key from the lock itself.

For an all-keys-lost visit we check photo ID and the title or registration, then cut a key to the bike's locks where it stands and test it in the ignition, the tank cap and the seat or tail lock. With no immobilizer described for these models, a correctly cut key should be all the bike needs. We will still ask for the VIN first, because a later F4 1000 can look very similar and may be equipped differently.

Where to find the key code

MV calls it the key identification number. The early manuals give a blank KEY No. field on the identification page for you to fill in, so look there first, then in the sales folder. These models are not described as having an MV Code Card.

MV Agusta F4 750 and Brutale 750 key FAQ

Does an MV Agusta F4 750 have an immobilizer?

The owner's manuals for the F4 750 S, S 1+1 and SR describe no immobilizer and no Code Card, only a duplicate key and a key identification number. A cut key is what these bikes use.

I cannot find a Code Card for my Brutale 750 S. Is that a problem?

The 2004 Brutale S manual does not mention one. What it asks you to keep is the key identification number, which is needed when ordering a spare key.

Is a Brutale 910 the same?

MV's 2005 Brutale 910 S manual has the same key text: a key supplied in duplicate and a key identification number, with no immobilizer or Code Card. It has its own page. The later F4 1000 differs by year.

Can one key open the F4's tail section and fuel cap?

Yes. MV supplied one key for the ignition and all the locks, and the SR handbook shows it used in both the tank cap and the glove compartment lock under the tail.
