Today I’m gonna show how to add a 2024 Toyota Highlander smart key with Autel MaxiIM IM508S. You may need a Xhorse XM38 Smart Key and 30pin adapter to plug in.
Step1. Generate Remote
I use the Key Tool Plus to successfully generate XM38 Toyota Remote.
Remote cloud recognition >> Remote program >> All remotes >> Sienna/Sequoia(BA) 8A Smart 312.1/314.35 >> Generate
Burn success.
Step2. Back Up IMMO Data
After connection, I’m going to pick the VENZA HV option on IM508S because I know that’s on the new system.
IMMO >> AutoVIN >> Toyota(Asia) >> OK >> Yes >> Control unit >> Keyless System(CAN) >> Back up IMMO data
This function is used to back up EEPROM data of the smart main ECU, which can be used to perform IMMO related functions without PIN.
This function supports models with 8A-BA smart key as of 2022(equipped with TMLF19D smart main ECU).
Press Yes to continue.
Ensure that the network connection of the IM508S device is good.
Turn ignition off, and turn the hazard warning lamps on and off once.
Read operation guide, press OK.
Reading EEPROM data…
Save EEPROM file.
Step3. Add Smart Key
Add smart key >> Start
This function serves to learn keys. Please complete the steps within specified time.
Turn on the ignition.
Confirm VIN.
Have you backed up the EEPROM data of this vehicle? Yes
Select the EEPROM data
Reading PIN…
Keep a learned key close to the start button.
Learning succeeded.
Test the new key, all buttons can work.
And I don’t have to adjust frequencies and buttons.
Perfect done.
