ALL: Programming New Keys
Keys for modern Vespa scooters have an RF (radio frequency) transponder in them that is read by the scooter in order to deactivate the immobilizer. It's not enough simply to have a key cut to the same pattern, as you would with ordinary keys. You must also follow a specific procedure in order to "tell" your scooter about the new key. Performing this process makes your scooter "forget" about any keys that are not included in this process, so make sure you have all your keys together at once for this procedure.

You must have the brown / red key that came with your scooter when you purchased it. If you don't have this key, you will not be able to make a new key work on your scooter, and your only recourse will be to replace the entire ECU unit of your scooter at significant expense. The brown / red cannot be replaced. The plastic card with a key code on it that may be in your instruction manual is worthless.

Here's the procedure:
- Have all your keys lined up. First the brown / red key, then all your blue keys.
- You have about 10 seconds to do this procedure. Timing is important.
- Put the brown /red key in ignition, turn it to the on position (without starting the engine) and then turn it to the off position within 3 seconds.
- Put the first blue key in the ignition, turn it to the on position (without starting the engine) and then turn it to the off position within 3 seconds.
- Put the next blue key in the ignition, turn it to the on position (without starting the engine) and then turn it to the off position within 3 seconds.
- Do this with all remaining blue keys.
- Put the brown /red key in ignition again, turn it to the on position (without starting the engine) and then turn it to the off position within 3 seconds.

Once you've completed the procedure, go back and check to make sure each key can start your scooter. If not, repeat the procedure. Again, timing is important. If it doesn't work, you probably took too long to perform the procedure.

It's been reported (but not verified) that the direction / orientation of the key matters during the procedure. MV member lomunchi reports:
"This didn't work for me either till I was mindful of the orientation of all the keys. I did the above with the keychain hole up for each one and it worked correctly."

The main issues by programming a new Key (with existing brown Masterkey):
wrong spare key -> there a two/three different blanks, depending on model year
to slow for programming, instructions say up to 10seconds between steps -> try to be fast as possible
No/to short break before testing

To verify compatibility double-check FIN
Model year 2013 to 2017/2018 = "MINDA" = SKU 656873:

Model year 2017/2018 to 2022 (including all HPE) = SKU 1B004020:

Best practice to program new key:

1. brown key/master into the lock
2a./2b. switch ON / OFF (leave master inserted!)
3. fold out chip from master
4. hold blue key upside down next to lock, so that the chip of the blue key is closer to the ignition lock than the unfolded chip of the master.
5a./5b. switch again ON / OFF
(to learn a second blue key repeat steps 4 + 5a +5b with another blue blank)
6. retract the chip of the master key (hold the blue key(s) away from the lock)
7a/7b again ON/OFF
8. wait 30 seconds
9a./9b. test with chip of master key unfolded and chip of (first) blue key close to lock (switch ON/OFF) -> test again for second blue key (if programmed)

For understanding: the brown master key stays in the lock during the whole procedure, with this key you do all locking operations. It depends only on which key the chip for the respective step is closer to the lock (brown/blue), so you save the re-inserting of the keys and can achieve the required speed.

Method above can be done before the new blank gets cut at a locksmith, so you are sure it will work BEFORE you pay money for cutting

Important are the 30 seconds pause before you test the new blue key.

Note: If you are using no keyring in brown key you can separate Chip instead of unfolding…
