Not exactly correct. The car needs a special hardware module such as from Viperware in order to use a Smartphone to remote start the car. And like traditional remote start systems, you will still need the ignition key inserted to actually be able to drive the car.

Just picked up a set of 2 gauge x 20' long at the local Autozone for a relative. They come with a storage bag & instructions are printed on the bag.

It's been so long since I've done it, I forget how.

It's connect both ends on the live battery, and positive end and ground to frame on the dead-battery car, right?

positive terminal goes to positive terminal.
your negative terminal (good car) goes to ground on the dead car.

that's the recommended approach.
but quite often I just connect negative to negative ... and am very careful not to spark the wires as I connect them.

That strikes me as being unlikely. Most chipped ignition keys use RFID technology, and there's no RFID transceiver on any blackberry I've heard of. Car manufacturers would eventually stop using it if it was so easy to circumvent.

You can build an RFID cloning transceiver, but you'd also have to defeat the lock on the steering column.

Not to mention you can order online diagnostic tools that plug into the onboard computer. I'm sure someone can force open your hood and plug one of those in and turn a car on and take it for a ride.


Easier still to get at it through the OBD port, but again you have to defeat the RFID "immobilizer" and the steering column lock to drive it away.[/quote]

Pete, what do you drive? Because then I'll know what car not to buy next! smile

Are you serious, hot wiring still works on modern cars? With or without the key in the ignition?

Edit: Wait--what? Key in the ignition? LOL, it's like the joke about the drunkard who drops his keys at night and looks for them under the streetlight--because that's where the light is!

I've noticed some new vehicles are forcing somewhat proper jump-starting techniques. My newer Chevy, for example, doesn't expose the battery's terminals. To boost a vehicle (or get boosted) you pretty much have to use their exposed, remote positive terminal and the vehicles ground.

Here's a picture I found online of a similar vehicle under the hood:



The red cap is the remote positive terminal and that black box to the left of it is the enclosed battery. Not shown in that picture is the ground; for this they also provide a terminal to use near the battery on the firewall (you can see it in this video). I'd say its an obvious terminal but I've forgot it was there before and clamped elsewhere smile.

What, an auto manufacturer exhibiting common sense? Inconceivable! shocked

Truck has 2 Sears platinum AGM batteries,same as military uses only branded Sears with 100 dollar less price tag. Very powerful.I dont think there is any other battery that packs more amps than this,at least when I last researched em.

Young fella with dead Honda,hooked him up.He says you need to start yours. Just go ahead says I.

Started him like he had 2 Sears Platinums.

Want a really really good battery for vehicle,thats it.
