ID46 Chip 433MHz SIP22 Blade 3 Buttons Smart Key Battery Included
Aftermarket Alfa Romeo compatible smart key featuring an ID46 chip, 433MHz frequency, 3 buttons and SIP22 blade. Suits Alfa Romeo 159 (2005–2011), Brera (2005–2010) and Spider (2006–2010). Battery included. Complete smart key with all electronics inside — diagnostic programming by a qualified locksmith or mechanic is required.
🔑 Smart Key Design: This is a smart key — unlike a flip key, the blade does not fold in. The SIP22 blade is fixed and integrated into the key body. Verify your current key is a smart key style with a fixed SIP22 blade before ordering. This key is different to the Alfa Romeo 147/156/GT flip key.
⚠️ Diagnostic Programming Required: This smart key must be programmed by a qualified automotive locksmith or mechanic using diagnostic equipment. It cannot be self-programmed. Please confirm your locksmith has Alfa Romeo compatible diagnostic tools before purchasing.
