Hi, I'm Chad. Welcome to JustAnswer. I'm reviewing your question and I will be posting your reply ASAP.

Expert:  Chad Farhat replied 2 months ago.

what we need is a diagnostic scan with a Toyota scanner or equivalent to read , the antitheft module and retrieve the fault codes to see what failed

the key, the antenna receiver , the door switch, hood switch, the module itself etc...

it could be in the door lock module actuators also .

But for now you can try this in case it will reset for now

Master reset Procedure

1- Disconnect Battery Cables ( Negative & Positive Cables )

2- Hold cables Together for 60 secs ,then let go

3- Wait 15 minutes

4- Make sure all doors are closed

5- Reconnect battery Cables

6- Lock & unlock the vehicles using the key from driver door side (if you have a key fob with no blade key, just lock & unlock using the key fob buttons)

7- Enter the vehicle and attempt to start

Please let me know

Thank You
