Same problem on my Vespa PX 150. Watching for any working solutions.

Saved me from towing my Vespa PX 150. Thanks!

Will this work if the Vespa PX 150 has an aftermarket alarm?

Common questions about key programming, fob issues, and replacement options

Key Programming
Programming syncs the key's transponder chip with your car's immobilizer system. The process varies by manufacturer but generally involves: 1) authenticating with the car's computer 2) erasing old keys if needed 3) programming new key codes 4) testing functionality.
Key Tip: Avoid exposing key fobs to water or extreme temperatures

Security Systems
An anti-theft system that prevents the engine from starting unless it detects the correct transponder chip in the key. The chip sends a unique code to the car's computer when you turn the ignition. No match = no start, even with a physically matching key.
Key Fob Issues
Many cars have a resync procedure: 1) Press lock/unlock buttons while near the car 2) Insert key and turn ignition on/off in a specific pattern 3) Use a sequence of button presses. Check your manual for exact steps - procedures vary widely by manufacturer.
Key Tip: Store your key code separately from your keys
Key Programming
Some vehicles allow DIY key programming using specific sequences (like turning ignition on/off with original keys). However, most modern cars require specialized equipment only locksmiths or dealers have. Check your owner's manual for your specific model.
Key Fact: Smart keys use radio frequencies between 125 kHz and 2.4 GHz
