Aprilia RS 660, Tuono 660 and Tuareg 660 Key Replacement

Quick answerThe Aprilia 660 twins come with two pre-programmed transponder keys, and the dashboard accepts a maximum of four. A five-digit user code, 00000 from the factory, lets the bike start if the immobilizer faults and is needed when keys are programmed. If you lose one key, replace it promptly: resetting a forgotten code needs both stored keys.

What the owner's manual says about the keys

The dashboard on the 660 has an immobilizer that prevents start-up unless it identifies a key that has already been stored. Each key has a transponder in the grip that answers a radio signal from an aerial inside the ignition switch. The bike is delivered with two keys already programmed, and the dashboard accepts up to four. Enabling a new key or disabling a lost one is done by an Aprilia dealer, and the storage procedure cancels the existing codes, so every key you want to keep goes along.

The manual also warns owners to keep the second key in a safe place, since it is not possible to make a copy if it gets lost, and says that would imply replacing numerous parts of the vehicle besides the locks. That is Aprilia's way of saying do not let yourself get down to zero keys.

The user code, and why to change it today

For about ten seconds after key-on, a new 660 asks you to enter a personal five-digit code, and it keeps asking at every key-on until you set one. The manual lists three reasons to remember it: the bike can be started if the immobilizer system is faulty, the dashboard need not be replaced if the ignition switch is changed, and new keys can be programmed.

If you forget the code, the dash has a Code recovery function in its service menu. It asks for key 1, then key 2, each within twenty seconds, and then resets the code to 00000. It only works with both stored keys. With one key and a forgotten code, that door is closed, which is the strongest reason to sort out a spare key and write the code down while everything still works.

The manual states that the key is used in the ignition and steering lock switch, the keyhole for the fuel tank cap, and the saddle compartment. The ignition switch sits at the front of the fuel tank by the steering headstock. Because one key does all three, a replacement key cut correctly to the ignition will also open the fuel cap and seat, and a damaged seat or cap lock can be repaired to keep working on the same key.

Lost key visit for a 660

We come to the bike and confirm ownership with photo ID and the title or registration. Tell us how many keys you have left and whether the user code was changed from 00000. With a working key and the code, adding a key is a short programming job. With no keys, the dealer path can mean replacement parts, and whether keys can be programmed to the existing electronics depends on the exact model and year, so we will confirm that before quoting. Typical market pricing for all-keys-lost work on immobilizer bikes is well above the cost of a spare.

Where to find the key code

There is no code card in the 660 owner's manual. The number that matters is the five-digit user code stored in the dash, 00000 unless an owner changed it. The chassis number, stamped on the right-hand side of the headstock, is what a dealer uses to order parts.

Aprilia RS 660, Tuono 660 and Tuareg 660 key FAQ

How many keys come with an RS 660?

Two, both already programmed. The dashboard accepts a maximum of four keys at the same time.

What is the default user code on an Aprilia 660?

Five zeros. The dash asks you to replace it with your own code at every key-on until you do.

I forgot my user code and have only one key. Can I recover it?

Not through the dash. The Code recovery function needs both keys stored in the bike. A dealer or specialist has to help from there.

Does the same key open the seat and fuel cap?

Yes. The manual says the key is used in the ignition and steering lock, the fuel tank cap and the saddle compartment.

My immobilizer light stopped flashing while the bike was parked. Is the battery dead?

Not necessarily. The manual says the light stops flashing after about 48 hours with the key off to reduce battery consumption.
