Verify your data door lock connection.

the car probably still has the tpms wire though.

Yes, you are right Robb. There is still a brown wire on passenger side blue connector for TPMS even car don't have TPMS. I thought if car was not equipped with TPMS then there is no need to connect that wire. I will try adding that wire and check today.

Thanks.
Hi Robb,

Would you please check module settings. I connect TPMS wires too but it does not make any difference to OEM remote control after start. Currently car starts with OEM remote but as soon it started, remote does not work at all. I am using Toy8 Harness with Evo One.

Thanks for your help.
OEM remotes staying functional should have nothing to do with the EVO settings. Turn OFF options E4 and E5 though.

 

The typical 2-3 reasons that OEM remotes do not work while the car is remote started are...

1. TPMS connection not done or improperly done.

2. Vehicle is equipped with a factory remote start and must be taken out. This is for every Toyota/Lexus.

3. Issue with door lock data connection (you have a harness but technically there is a connection in there for door lock data, see non t-harness guide)
Thanks Robb. We don't have factory remote starter but will check guide for non-t-harness if that works.
Hi Robb,

So i added data door lock wire manually as per your suggestion. OEM remote works now for unlocking after start but why does car unlock before starting. It is unsafe for someone to simply open door at that time. It is fine after 10 seconds that car lock after start. How to fix that.

Thanks for your help.
All remote starters function like that. The unlock is to disarm your oem alarm or else it will start to ring. If your vehicle does not have a factory alarm, simply disconnect the disarm wire..
If i disconnect factory alarm, would it still unlock before start or not.
As mentionned, it's unlocking because of the disarm wire connection. If you disable your oem alarm, which i do not suggest, simply disconnect the disarm wire
