How to Update Londsor Toyota PH0440B Smart Key?

Problem:

I had a problem reading Lonsdor key information with Lonsdor KH100+ key tool. It was FT02-PH0440B smart key.

It should be ok for RAV4 19 – 21. Any solution?

Solution:

Update ph0440b key version with Lonsdor K518ISE.

Menu path: Special functions-> Key settings->FT smart key-> 8A->Upgrade key

Don’t remove the key during upgrade procedure. If the key light stays on, update key again.

Read ph0440b key again after upgrade, if still read failed, change key positon and try more times.
