Modern Vespa

Folks I have a Vespa GTS 300 2023, my key fob is showing no lights and on the display it is showing "key fob out of range" it is also saying this for the back up key. The bike is running fine apart from having to put the fob close to the indicated left side marker. Question is there a specialist battery for the fob? How do I get rid of the message? Do I need to take the scoot to a dealer to fix problem?

Sounds like your key fob battery needs replaced:

Thanks for that, I have replaced the battery twice before, I will do it again to see if it makes a difference and look at the instructions to see if I can recode the fob to get it going again..

If placing the fob by the sensor on left works, then it doesn't need recoding. If you replaced it twice, then you got a set of bad batteries, inserted it upside down, got contamination on the contact area, or maybe damaged it while opening/closing the case .

The "back up key" is the master key (a small black chip). You need this to be able to program a new Key-FOB at a dealer (PADS required!). So don't lose it! The master is passive (it has no batteries, so it only works directly on the left maintenance cover).

If the battery of the Key-FOB is empty, it also only works on the maintenance cover (it is also passive when the battery is empty). If the battery of the Key-FOB is OK, the active radio detection can be activated/deactivated by pressing both buttons (press both buttons until the LED changes color (red/green).

Yeah... don't lose or destroy the fob. A new one, coded will run just shy of $250.00!

Thanks everybody for your responses.

What is the status? Have you been able to find a solution? Please share it with us. Thank you very much!

I have changed the battery again no joy, there are no lights coming on in the key, when I use the back up chip key, it's still showing out of range. The scooter starts up and runs fine apart from the message on the display screen. We use to have a dealer in N Ireland, but we don't have one any more, the nearest one is at least two hours drive or across the Irish Sea, challenging to stay the least.

Measure the battery (or put it in another device) to make sure it has enough juice.

Are you sure it is inserted the right way top/down (see picture)?

Do the terminals make contact with the battery and are they clean?

The correct type is a 3V button cell CR2032. Correct. Detection is always passive with the master chip (as it does not have a battery). Logically, there is then no ACTIVE key in the reception area for the Vespa. Please note my comments above regarding the master chip (don't lose it!) and the passive Key-FOB!

IMPORTANT QUESTION: Does the passive recognition of the large remote control / Key-FOB work? See above. Annoying...

If the Key-FOB is defective, you will unfortunately have to take the master chip and the vehicle to the dealer. A new Key-FOB can only be programmed using the PADS diagnostic tool at the authorized dealer.

Has something happened to the key FOB? Rain, washing machine, dropped, etc.?

Thanks for your help, I must say you all have been most helpful, that will be my next option, taking it to the dealer.

If I have any other problems I know where to come.
