what i've got from your bios file,

MBP111.88Z.B03.1310291227
SSN : C02M9B4GFH00
USERNAME NORFAUZI JALALUDIN
MacBook Pro "Core i5" 2.4 13" Late 2013 2.4 GHz Core i5 (I5-4258U)

This is what i was doing with your locked files:

- Clear Password is by removed bunch after $SVS......

you can google for this treat.
But NVram must be clear too,
so how??

1. Get file : MBP111_0138_B03_LOCKED.SCAP (bios packaged update from apple)
2. Open MBP111_0138_B03_LOCKED.SCAP with UEFIToo.exe
3. Extract Body so you get UEFI_CAPSULE_BODY.ROM
4. Still on UEFITool closed SCAP file, now open 1502_ori.rom
5. Still on UEFITool open image in new window, choose UEFI_CAPSULE_BODY.ROM
6. See on 1502_ori.rom window,there is 10 file modules BIOS REGION, that module files should be replace from original SCAP
7. select on NVRAM module,
FileSystem GUID: FFF12B8D-7696-4C8B-A985-2747075B4F50
Full size: 30000h (196608)
this NVRAM module should be replace from UEFI_CAPSULE_BODY.ROM
8. now see on UEFI_CAPSULE_BODY.ROM window, click search choose GUID ,input FFF12B8D-7696-4C8B-A985-2747075B4F50,

GUID pattern "FFF12B8D-7696-4C8B-A985-2747075B4F50" found as "8D2BF1FF96768B4CA9852747075B4F50" in PE32 image section at header-offset 2914h
GUID pattern "FFF12B8D-7696-4C8B-A985-2747075B4F50" found as "8D2BF1FF96768B4CA9852747075B4F50" in TE image section at header-offset FC8h
GUID pattern "FFF12B8D-7696-4C8B-A985-2747075B4F50" found as "8D2BF1FF96768B4CA9852747075B4F50" in TE image section at header-offset FC8h
GUID pattern "FFF12B8D-7696-4C8B-A985-2747075B4F50" found as "8D2BF1FF96768B4CA9852747075B4F50" in FFF12B8D-7696-4C8B-A985-2747075B4F50 at header-offset 10h
S
elect the last,see that module for NVRAM with same size "Full size: 30000h (196608)", that module should be extract as is,
now you get CLEAR NVRAM module file "FFF12B8D_7696_4C8B_A985_2747075B4F50.rom"
9. now replace this module to 1502_old.rom.

try this..
1. Dont forget to reset nvram by holding Command+Option+P+R keys...

2. If you use old hdd, never using internet restore OS.. use usb or dvd for install OS
