Modern Vespa

My old key with remote got soaked in water so I gad to order a new one. I managed to program it so I could start my mp3 400 but the two remote buttons for the tunk and seat don't do anything now. The green light on the key comes on indicating the battery is working in the key remote. Did I do something wrong? Help!

did you follow the steps in the maintence manual below?


Remote seat opening
Zeroing
- Remove the left side fairing to access the saddle
opening receiver control unit indicated in the photograph
- Remove the metal terminal and connect it to a
good earth point, or to terminal 7 (black), for at
least 10 seconds.
- In this operation all the remote controls stored in
the control unit will be deleted.
WARNING
THE CONTROL UNIT CAN PROGRAMME UP TO 8 REMOTE
CONTROLS.
Programming
Follow these steps to program the remote controls:
1. Insert the remote control key to be programmed in the steering lock key block.
2. Turn the key to «ON», press the button on the remote control, release the button, then turn the key
back to «OFF» within four seconds of turning «ON».
3. Wait 1 to 8 seconds.
4. Repeat steps 2 and 3 four more times without removing the key.
The control unit confirms the programming has been successful by opening the saddle.
WARNING
TO STORE THE OTHER REMOTE CONTROLS TO MEMORY (8 MAXIMUM) YOU NEED TO REPEAT
THE WHOLE PROCEDURE AGAIN. FAILURE TO CARRY OUT THESE OPERATIONS
WITHIN THE INDICATED TIMES WILL RESULT IN THE AUTOMATIC CANCELLATION OF THE
PROCESS FOR PROGRAMMING THE REMOTE-CONTROLLED KEYS.
WARNING
AVOID PRESSING THE REMOTE CONTROL BUTTON MORE THAN ONCE WHEN FAR AWAY
FROM THE SCOOTER. THE SYNCHRONISM BETWEEN THE REMOTE CONTROL AND THE REMP3
400 i.e. Electrical system
ELE SYS - 87
CEIVER CAN BE IMPAIRED. SHOULD THIS BE THE CASE, REPEAT THE PROGRAMMING
PROCEDURE. DO NOT KEEP THE REMOTE CONTROL IN PLACES WITH TEMPERATURES EXCEEDING
60° C THE BATTERY WILL RUN DOWN TOO QUICKLY.
WARNING
TO AVOID BATTERY DISCHARGE, THE SADDLE OPENING REMOTE CONTROL RADIO RECEIVER
DEACTIVATES 7 DAYS AFTER THE LAST TIME THE VEHICLE WAS SHUT OFF.
JUST TURN THE KEY TO «ON» TO REACTIVATE THE RECEIVER.
Electrical system MP3 400 i.e.
ELE SYS

no I did not do this...any chance you could upload the picture for me? Thanks for all your help so far..you've been a godsend!

under the wiki page new key problemi (Post 988470) you can see the routine maintenance section, then workshop manuals, then select your model and you have the whole shop service manual at your fingertips.

BTW, I did not remove anything, but simply followed the part of the instructions to reprogram the remote and it worked just fine.

That would actually make sense since supposedly it will accommodate up to 8 remotes. No need to clear the unit first IMHO.
