Programming a Peugeot 107 key remote

When I bought a 2nd-hand Peugeot 107 it had two remotes, but only one worked. Changed the battery, still no good. Searched the web - suggestions for everything but 107.

Then I tried this sequence:

Drivers door open
Ignition off


Switch ignition On then Off

Close then Open drivers door twice

Switch ignition On then Off
Close then Open drivers door twice

Close doors and lock using manual knob
Switch ignition On then Off Twice
Unlock using manual knob

Observer doors lock and unlock

I waited a few seconds for everything to settle, then everything worked.

BOTH REMOTES WORK!

I don't know if anything needs to be done to the remotes before the above sequence as the remote came with the car.
