Peugeot radios unlocked online — from the serial on the unit, or from the VIN on RT6 and SMEG screens.
Older units — the serial. Pull the radio out with a pair of release keys and read the label on the casing: 14 characters starting PE.
Nothing needs unplugging — the unit only has to come forward far enough to read the label.
RT6 and SMEG screens — the VIN. These have no serial you can read; the code is built from the car’s VIN instead, which is on the plate at the base of the windscreen, on the door pillar and on your registration document.
One thing the VIN does not tell us is which screen generation is fitted, and each builds a different code — so the form asks. The manufacturer’s own tool asks exactly the same question.
Worth knowing before you start. On these screens the code is not always what unlocks the car: a unit that was swapped between cars is normally re-paired to the VIN with dealer diagnostics instead. If your screen never asks for a code, nothing here applies — and since no owner has confirmed this rule to us yet, we charge nothing for it either way.
Serial number example:
PE670FA3000401
17 characters, no I, O or Q — for RT6 and SMEG screens.
