Default Official Toyota Remote Start for Prius? UPDATED (Answer: No)

Hello all; long time lurker. We bought our red 2006 Prius three weeks ago and are loving it. We picked up the new 2007 Prius accessory brochure, and featured prominently in the brochure is this: "VIP Security - RS3200 Plus System. Start your vehicle from 75 feet away. Preset your radio, air conditioner and heat controls. Have your car ready to go."

We've been looking for a remote start solution since we got the Prius; cold Michigan winters. It's my understanding that previously the RS3200 remote start was not compatible with the Prius, but this brochure is an official Toyota brochure specifically for the Prius.

So my question is, has anybody heard of this, and any word on whether this is compatible with the 2006 Prius? I'm hoping it's not a 2007-only option...

If one can remote control the accessories, that would be cool! Considering that practically everything in the car is networked, that does make sense.

I would be concerned however about the vunerablility of the immobilizer if such a device could actually start the car. Even if the remote start acted as the fob and had to authenticate itself in order to READY the vehicle, what protects the remote start from falsely authenticating the car to READY? That's like the equivalent of hiding a disabled fob in the car, ready for a thief to use if found and enabled.

I'm not up on the precise inner workings of the Smart Key system, but on our other car with remote start, the remote start runs the engine but requires the key to be put in the ignition and turned to the Run position before the brakes are pressed to allow the car to be shifted from Park. If you step on the brake before inserting the key, the engine is killed.

Taking this to the Prius Smart Key system, I would assume that the Remote Start authenticates and starts the engine, but the immobilizer will kick in if the transmission is attempted to shift without the Smart Key fob present.

Maybe there's a new mode. Between "IG-ON" and "Ready" that connects the HV battery, but doesn't allow the drivetrain to be engaged.

Owner of 'Eeyore', a 2004 Prius. Only took 2 days from start of search to delivery.

8 years of ownership, 115,000 miles, about 40 MPG average at present.

Then what's the point? OK, might be beneficial for AC for a short while, as long as the SOC doesn't give out, which in a superheated cabin would be about 5 minutes. For heat, that requires ICE, since the suplement electric heat doesn't seem to be very effective.

But the 'tranny shift' is really instructions to the HV ECU as to what direction to go, and to disengage/engage the parking pawl, so it could work as cshbell described. If that's the case, then the car would have to have compatable programming, so the remote start may not work on earlier model years.

If it's compatible with a 2005 I'd buy a remote start tomorrow. Please keep us posted. (Little snowflake adorned my dashboard this morning.)

Don't put off till tomorrow what you can do today.

Remote start on the prius just doesn't seem all that practical to me, at least as it would be implemented in the Prius. You would be better off with some sort of block heater. Folks have done that around here and have reported good luck with it.

It has been said:
Hybrid drivers come in 3 flavors, greenie, techie and cheapie. Pick any 2.

Hello DanMan32,

I was away from this forum since June ! The CH or the Camry Hybrids has this option feature available. You can start the system from 80 feets away and you can enjoy the Heat or Cold when you decide to enter the vehicle. However if you do not have the HKS Fob with you the doors are locked and then the system shuts off ! So no concerns about the vehicle beeing stolen. Anyway it is good feelings to be back to the awsome forum, PriusOnline !

For a Prius, if workable, a remote car starter might actually be an ok feature as it wouldn't be a case of the ICE idling for minutes to warm up as in a conventional vehicle. Warming up a conventional vehicle for more than 30 seconds, with the exceptions of very cold weather (10F or colder) or if a diesel, is not necessary. Driving the vehicle slowly to get lubricants flowing is the ideal warmup procedure. Remote starters encourage unnecessary idling which causes respiratory illness, wastes fuel, contributes to climate change and damages engine components.
