How to program SUBARU Forester Smart key all keys with K518 / X300?

SUBARU Forester Smart key all keys lost adapting with Lonsdor K518ISEOBDSTAR X300 DP, I80 key programmer.


We all knows SUBARU spare parts is very expensive, all key lost will cost a lot, here we share the SUBARU Forester key

adapting method for all key lost.


SUBARU Smart key all key lost key adaption have two common methods:

  1. Disassemble the SMT Main ECU, Use AD900 programmer to write data into Toyota smart key, it can directly start the car, No need adapting on the car again, but must use AD smart key.
  2. Disassemble the SMT Main ECU, immobilizer(ESL/ELV), Write initialization data, then study the key on the car.

Here we share the second method, SUBARU Forester use 5290 smart key, Year 2013, No immobilizer, disassemble the SMT Main ECU and ELV Write initialization data and study the key.


  1. Get the ELV(below steer column), disassemble the ELV module, find the 8 PIN EEPROMon the circuit board, Model No. : 93c46.

Desoldering the 93c46, use programmer and adapter read the data, make a backup first then change the code shown as below picture.

-keep the Red marked code code the same, others all change to F, When dump revised, use programmer and adapter write back to 93c46 eeprom, and solder back to the circuit board.

  1. Disassemble the SMT Smart ECU(back side of the A column of the car), it’s appearance is the same as Toyota except the LOGO, disassemble the shell find the 8 PIN eeprom near the CPU, EEPROM Model No. : 93C86. Disassemble the 93c86, Write initialization data, assemble back to the car, if without error the dashboard could be light up.
  2. Use Key programmer add new keys directly. Use Lonsdor K518ISE, OBDSTAR X300 DP, or I80 key programmer, connect the car OBD interface, select SUBARU, then XV smart system, direct add new key, all down, after the keys added, no need sync, directly start the car.
