Hi, sorry to bother, but a forum member advised to write this here also..
Just bought a 1996 P406, with 2.0L petrol engine. Car is in good condition and just inspected, but a mechanic fixing brake lights happened to see unplugged wire, and put it in. Well, this wire was keypad connector which was disconnected to prevent the need to input pin code in every start. This has been used for years, and now when car wants the code (which is not original 1111), none of previous owners remembers it.
So, I have tried to figure out way to bypass the keypad. Keypad itself seems to be a "dumb box" without memory. Car has Bosch Motronic 5.1.1 ECU, where I found one eeprom, B58097, equals 93C46. Immobilizer should be off by reprogramming first 6 digits to 00 (right?). I haven't done this yet.
Does anybody remembers how this works? Where is the passkey code burned, to read it, overwrite it or disable it? Can I use some jumpwire to tell car to "go"?

Re: Old school problem, Peugeot 406 keypad
Hi and welcome. I don't think any BX had a security keypad but the XM did and I think the factory code was 4444. If that fails then there is a way to find what the old code was with a bit of detective work shown here by Seppo of Seaside Garage.
