Hi Jonas2,
I see 2 things I question:
1. IF i = 4 THEN GOTO confirm ' code complet ? oui confirme
0 to 3 so it should be complete @ 3

2. You are exiting a for next loop in a rude fashion. I would tell the loop row = 3 and then gosub. IMHO
Like so

Code:

---

FOR row = 0 TO 3                    ' 4 rows in keypad
            PORTB = 0                            ' All output-pins low
            TRISB = (DCD row) ^ $ff              ' Set one row pin to output
            col = PORTB >> 4                    ' Read columns
            IF col != $f THEN row = 3              ' If any key  own, exit
            NEXT row
            Gosub gokey
            return

It just clears the stack. AND Maybe your pause 100 is faster than your key finger too :D

Hi

Yes, but the variable code0 has 1, 2 account code1, code2 account 3 code 3 has 4
IF i = 0 THEN
code0 = 1 >>>>> xkey
endif

IF i = 1 THEN
code1 = xkey >>>>>> 2
endif

IF i = 2 THEN
code2 = xkey
endif

IF i = 3 THEN
Code3 = xkey >>>>>> 4
endif

PAUSE 50

i = i + 1
IF i = 4 THEN GOTO confirm

So it is, I think the problem comes from the relaxation of the?
