Key less start

[SolidusJ]

Thinking about a new project when I get home, looking at the Cadillac key less start fob. Just want to learn how the Hummer's work with their key fob. Are they program into the BCM or a whole different box runs them? I think it would be pretty awesome to have a push start button set up and have the key fob so many meters away to work. This is all "what if" but better to learn the inside and outs before taking a step you can't come back from.

Basically you would need a button, a resistor and a few relays. If you want the button to only work when the remote is in the truck you would want an RFID receiver in the mix.

The more I think about the more I can see going wrong with OnStar. I think it would better to go with the Viper alarm system or something, it would be nice to have an auto start on those cold days. I seen on a few forums that installing the system you can't go by the paper work they give you and have to an relay to something or another. Maybe I can get some auto shop to work something and see if they can make the Cady remote work also?

Onstar doesn't have anything to do with the starting system. A remote starter would require a resister like a button start would. I don't know it the Caddy remote uses the same RF as the H3. Sticking an RFID tag inside your H3 remote would do the same thing.

Have you ever driven a Caddy with the keyless ignition? It can be a PITA.

Not only does Onstar not have anything to do with keyless starting, remote starting has nothing to do with keyless starting.

Like Steve says, keyless starting has a lot of faults and offers nothing over a key start system.

Go with a Viper or Python, I did and have never had a problem. And the remote start allows the vehicle to run for 20 minutes, my silverado with remote start only runs for 10 minutes.

And all H3 remote functions are controlled by the BCM; unlike some vehicles that use a remote control door lock actuator module.

I would much prefer to have remote starting than keyless starting. Can't really see much benefit to keyless starting, unless one has a hard time getting the keys out of the purse
