MK3 Program Toyota VIOS 2014 G Chip when All Key Lost

MK3 MKIII Key programmer is good at programming Toyota and Lexus Smart key H/G Type. Here is a tutorial on programming Toyota VIOS 2014 G chip in EEPROM 93C66 when all key lost. Good luck!

 

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

 

mk3-program-toyota-vios-2014-g-chip-all-key-lost-1 mk3-program-toyota-vios-2014-g-chip-all-key-lost-2

Read EEPROM 93C66 by WELLON Programmer, Click read

mk3-program-toyota-vios-2014-g-chip-all-key-lost-3

Read OK

mk3-program-toyota-vios-2014-g-chip-all-key-lost-4

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)

mk3-program-toyota-vios-2014-g-chip-all-key-lost-7

Next open EEPROM 93C66 file and it will show you the information of keys

 

mk3-program-toyota-vios-2014-g-chip-all-key-lost-8 mk3-program-toyota-vios-2014-g-chip-all-key-lost-9

Now this cat all key lost

Next i will show you how to make new key4 master

Put G chip on MK3 key programmer

mk3-program-toyota-vios-2014-g-chip-all-key-lost-10

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!!!

mk3-program-toyota-vios-2014-g-chip-all-key-lost-17

Finally, sold EEPROM93C66 back to PCB board

mk3-program-toyota-vios-2014-g-chip-all-key-lost-18

Now we make 2 master key and 1 valet key. Put the G chip into key shell

mk3-program-toyota-vios-2014-g-chip-all-key-lost-19

Try to use these keys to start car, all keys worked!
