Remote Start Anyone?

[2manysubies]

I would imagine that the Limited may have to have a chip of some type in the car for a remote starter to work, possible some type of modified chip where if it gets put in gear or senses movement, the car will shut off unless it "see's" the real key.

What would happen if I have the push button start and I go outside to start it and then come inside with the key fob? Could someone open the door and take off with the car?

If it's anything like other push button start cars, it will turn off as soon as they try to drive off. I'll test it out later today unless someone else confirms.

I would expect that the doors would be locked.

Actuuuually, that's what you would think. I thought so for longest time.

Haven't tested with BRZ yet, but a lot of cars allow you to drive without keyfob as long as car is started. Once you shut it off, that's a different story... Won't turn back on without the keyfob.

I work in a bodyshop and have seen Nissan, Toyota, and Lexus do this. Not sure if its on all models or not. Other makes I'm also not sure of since its not something we make habit of doing.

One instance was when a customer had a rental Altima and left key on top of car when putting stuff in. They forgot key and drove home. Lol... Had to tow car back to us so we could get new key and get it reprogrammed.

Brz limited has a factory proximity sensor and yes, key is chip.

Yeah you're right - come to think of it, the only ones I've seen that shut off are the ones with remote start capabilities. In other words, if you remote start the vehicle, then someone tries to drive off with it, it'll shut down. If you've physically started the car by being in proximity of the sensor and pushed the start button, then left the car, I suspect it will continue to run even if you put the keyfob somewhere else away from the sensor.

My IS350 does this...if you start the engine with the keyfob but put the keyfob outside of the car, you are still able to drive the car regardless.

I think what we're missing here is the consideration of a dead battery in the key fob.

If they decided to implement a kill engine switch whenever the car is unable to detect the key fob, that would mean running the risk of an engine stopping dead on a freeway because of a dead key fob battery. That would be pretty scary imo. Who knows, maybe the engine DOES turn off when you try to drive it without the key. I kind of doubt it myself, but I'll try it when I get back home.

I do it all the time i park my truck behind my car. so when i want to take the car i get in start it get out with the key start my truck move it out of the drive way. then i come back without the key (my whole ring of keys is in the ignition o my truck) move the car out of the drive way and put the truck back in.

What's weird about keyless entry cars with start button is that even with a dead battery, as long as the keyfob is close (I mean, right next to the start button), it will usually still start. It's a safety feature... learned that hard way at my shop. Usually doesn't apply to the doors.... only ignition.

The thing is, I doubt that will be any help, unless they high thee keyfob behind the start button...

It's a redundant system, in the same manner as cars with pushbutton door latches also have a mechanical latch handle somewhere.

The fob is a transmitter, and as long as the battery in it is functional, it works from a distance. The fob also contains a passive RFID component, and when the fob battery is dead, holding the fob next to wherever the reader is located serves the same purpose. On Corvettes, there's a little slot in the dash behind the glove box door - you slide the fob in that, and you're good.

On GM cars, it's part of the customizable features as far as what you want the car to do in that case. The default setting is as you say, keep running but don't allow restart.

interesting, i never knew there was an RFID in there! that explains everything...good to know!

I think pretty much all keys have RFID elements now - GM started the idea with the PassKey systems in the late '80s, where there was a resistor embedded in the key shank. When you inserted the key into the ignition, there were terminals that 'read' the resistor, and if the value wasn't correct it shut down the fuel system for fifteen minutes.

There were something like ten different resistor values, so a potential thief might have quite a wait. Corvettes had it first, and they went from the most-stolen cars to basically dropping off the list in the space of a year.

Now everybody does the same thing with RFID. It's how you can personalize by key, and it's why keys cost $50 or whatever insane amount it is.
