Sorry to bump such an old thread, but people still reference it, and I solved the mystery of why the posted code for 0 doesn't work. A long press of the 0 button on the original remote is the System Wizard command which matches the posted code exactly (OBC 56). The short press of 0 should have been learned instead.

Here's the correct code for 0 (OBC 17)

0000 0048 0001 0011 0017 015F 0017 00A4 0017 005E 0017 00A4 0017 00A4 0017 00A4 0017 005E 0017 00A4 0017 00A4 0017 00A4 0017 00A4 0017 00A4 0017 00A4 0017 00A4 0017 00A4 0017 00A4 0017 00A4 0017 015F
