Sometimes when people add key or programs all keys lost for a new 2022/2023 Toyota Camry push to start, the keys start the car but remote don’t do anything. Here’s the clue.
First of all, check your keys. FCC, ID and frequency should be 100% match.
You need OEM key with correct FCC and IC.
If the key is brand new from Toyota by VIN and customer’s original key starts the car but no remote. It is not the problem of the key.
One of obdii365.com customers had this same problem a while ago with Camry 2023 AKL and had to use smart pro to re sync the keys and then it worked.
You need to sync remotes again. You have to register the ID’s back to the smart box.
It’s a common problem with those new style Toyota keys. Have to re-register remote ID’s to enable remote keyless function.
You can go under Diagnostics->Control module->Special function, and click on the ECU communication ID registration.
The ECU communication ID should be registered when the transponder key ECU and/or the ECM is replaced in order to match it to the ECM COMMUNICATION ID.
Go to Immobilizer->Lexus->Select selection->Keyless System->Keyless System (CAN)-> ECU synchronization learning->Synchronize ID authentication box and steering lock.
Turn on ignition switch and make sure START button function is off.
