Yaris and Viper 4204v remote start

[CTScott]

OK - You will definitely need a transponder key bypass module. I used the Fortin KEY-OVERRIDE-ALL on my Yaris.

Also, before doing anything, make sure that you can kill the alarm by unlocking the door with the key (and without using the key fob). The Toyota OEM alarm does not have an input to disable it when remote starting (except by CAN Bus message), so you would have to rely on killing it by hitting the key unlock detect circuit.

I only could find xpresskit pkall around here. I see several types of t-taps. Which one I should use?

The xpresskit one is fine. For the t-taps, I always buy the 3M ones, but really any will do. In the case of remote starting a Yaris, all of the connections are relay coil side, rather than contact side, so it is all low current.

Did you test the key disabling the alarm?

I mean what gauge t-tap. Yeah I kill the alarm by pressing the unlock button on my key.

You will need t-taps for 22-18 AWG wire.

With killing the alarm, you need to test by unlocking the door with sticking the key in the lock, as opposed to pressing the button on the the key. The button press goes through a way that the remote starter will not have access to.

Non-remote car key can kill the alarm by unlocking doors. So does it mean that I can connect the oem alarm to the remote start?

I believe so. Also, try getting in, locking the doors, arming the alarm, and then starting it to see if the alarm triggers.
