if i grt another keypad with the code will it work on my 406 ?

you can change the numbers on the key pad you must have the code that is being used .pick numbers that are not worn as these will work ok. then you need the instructions of the peugeot booklet how to do it.it takes a a4 sheet to photo copy it but its easy to do the code for the pads are in the ecu so i do not think a key pad will do what you want
