Regroup everything into pairs of 3.

Convert Decimal to ASCII

Alternatively you can use the shorter version:
Group the code into pairs of 2
50 12 60 11 14 41 50 11 51 01 15 41 01 11 01 11 15 40 50 15 40 50 17 10
Reverse each pair
05 21 06 11 41 14 05 11 15 10 51 14 10 11 10 11 51 04 05 51 04 05 71 01
Regroup into pairs of 3
052 106 114 114 051 115 105 114 101 110 115 104 055 104 057 101

Think about the passcode format and where what values should/could be.
See what Grids you can form.
Try to rearrange the numbers to fit the ranges for a base conversion.

Arrange the code into a 3×10 grid.

8	0	5
1	8	3
5	4	7
0	7	1
6	3	7
6	7	9
8	8	6
1	5	2
5	0	7
0	7	7

Reverse each row

5	0	8
3	8	1
7	4	5
1	7	0
7	3	6
9	7	6
6	8	8
2	5	1
7	0	5
7	7	0

Group up the numbers again, reading left to right. Make pairs while grouping them
50 83 81 74 51 70 73 69 76 68 82 51 70 57 70
Convert decimal to ASCII for the solution

Everything is there, just need to rearrange it all so that we can read it in the right format.

Make a grid of 4×4 with the code

o	o	f	a
u	l	l	6
a	g	a	z
4	9	b	3

Starting at the bottom left, read each column up for the solve.
