Using MK3 program Toyota VIOS 2014 G Chip when All Key Lost for you
Device Needed: 
MasterKeyIII MK3 Key Programmer
Wellon VP380 Programmer

Vehicle model and year:
Toyota VIOS 2014
 
Following the procedure:
Before doing the job, you should take IMMO box from switch START, then take EEPROM 93C66 out

Read EEPROM 93C66 by WELLON Programmer, Click read
MK3-Program-Toyota-VIOS-2014-G-Chip-All-Key-Lost-3
Read OK

Then save the file named “29102016-car2.bin” to desktop
MK3-Program-Toyota-VIOS-2014-G-Chip-All-Key-Lost-5
Then open MK III “MasterKey3 software”
Then choose Utilites -> Key Generator -> Key By Dump
MK3-Program-Toyota-VIOS-2014-G-Chip-All-Key-Lost-6
Choose T-> Toyota ->IMMO-> G Chip,93c66(immo Toyota 89780-xxxxx)

Now this cat all key lost
Next i will show you how to make new key4 master
Put G chip on MK3 key programmer

Choose “Key4” and press WRITE button
MK3-Program-Toyota-VIOS-2014-G-Chip-All-Key-Lost-11
Now already written new Key4 in EEPROM file
MK3-Program-Toyota-VIOS-2014-G-Chip-All-Key-Lost-12
Then save to a new file
MK3-Program-Toyota-VIOS-2014-G-Chip-All-Key-Lost-13
Next, write new file back to EEPROM 93C66
Use WELLON VP380 to open the saved new file to desktop
MK3-Program-Toyota-VIOS-2014-G-Chip-All-Key-Lost-14
Put EEPROM 93C66 to adapter
MK3-Program-Toyota-VIOS-2014-G-Chip-All-Key-Lost-15
Then press “Program” button
MK3-Program-Toyota-VIOS-2014-G-Chip-All-Key-Lost-16
Programmed OK!!!
