Toyota highlander immo light flashing

[Kalectro]

Hi
I have a Toyota Highlander 2012 Engine 1ARFE.
After some work on the Air Conditioner system, the vehicle refused to start.
On Diag, no code in the engine, one code in the immobiliser system:

B2796 "No communication in immobiliser System"

Immo light start flashing when ignition is on.

Please help me solve this.

I have some news. I tried to read the key with my zedbull but the transponder is not detected. I try with xtool to add new key 4d67. On ignition off the immo light stays on, no blink. On ignition on, the light start to blink after 3 seconds. Vehicle won't start.
