Which Tool to Unlock Toyota 4A Smart Keys?

 Question: Possible to unlock Toyota Corolla Cross 2023 model 4A smart key? Is there a tool that can unlock 4A Toyota smart keys? Autel, Lonsdor or Xhorse?

Here is the clue.

You cannot unlock it. All these ID4A smart keys are locked. ID 4A can’t be unlocked with most tools yet. Only can be unlocked with mk tool.

Corolla, Corolla Cross and new Camry chip ID 4A is a different family than 8A. 4A is hitag 3 with AES encryption. Most cloner can not wake it up so doesn’t see transponder.

Xhorse, Autel, Londsor k518 pro cannot unlock 4A smart key, only 8A. For example, if you have vvdi mini key tool, go to Special function and click on Toyota smart key unlock and insert the smart key into the coil of the tool and it will unlock. You may have to do it over and over again. Read the smart key and it will be unlocked.

But 4A smart key doesn’t need to be unlocked. 

If add key, the 4A key does not seem to lock and can be programmed to other cars directly.

If all keys have lost, to program it you have to use KD or LONSDOR or TANGO emulators. You program in the emulator, then write it to the used key.

You need to back up the data do all keys lost via simulation even if it’s add key and you’d better use the simulator this bypasses the need for the code.
