<\/p>\nWorking on a 2014\u20132020 Toyota Aygo, Citro\u00ebn C1, or Peugeot 107\/108 with All Keys Lost (AKL)?<\/p>\n
These three city cars share the same platform and immobilizer architecture. In an AKL situation, programming a new key is more complex than normal OBD learning \u2014 and in most cases requires dashboard removal to access the immobilizer box.<\/p>\n
This guide explains two professional methods to complete the job successfully.<\/p>\n
<\/p>\n
Supported models (2014\u20132020):<\/p>\n
These vehicles were developed under a joint venture and use similar immobilizer systems.<\/p>\n
In an All Keys Lost situation:<\/p>\n
\u26a0\ufe0f Important:
\nYou must remove the top section of the dashboard to access the immobilizer and retrieve EEPROM data.<\/p>\n

<\/p>\n
<\/p>\n
This method avoids full immo box disassembly and saves time.<\/p>\n
This approach reduces labor compared to EEPROM desoldering.<\/p>\n

<\/p>\n
Many technicians fail here.<\/p>\n
For Aygo \/ C1 \/ 107 \/ 108:<\/p>\n
\u274c Xhorse Super Chip XT27A does NOT work directly
\n\u274c VVDI2 4D70 generation does NOT work
\n\u274c XT27 generating as 4D70 will fail<\/p>\n
\u2705 Only Original 4D70 chip works correctly with Tango<\/p>\n
This ensures stability and avoids repeat jobs.<\/p>\n
