2007 hyundai elantra remote start

Im going to be doing a starter install on a 2007 Elantra on site at a customers house today and im looking for all the hints and tips on doing this car please. I will be using a key in the box type bypass and im a little stumped about this key sense hookup if someone can help me find the easiest way to do that. I will be doing door locks and the trunk also.

Here's the wire diagram i'll be working off of.

You would need to energize keysense, yes. If you look at the notes for disarm/no unlock it specifies that the factory alarm will disarm with keysense, ignition and accessory. You do not mention which system you are installing, but with the DEI systems I use there is a status output wire that you would use to power a relay to provide +12V to the vehicle's keysense wire during remote start. You may also be able to just use the second ignition output to power it if your vehicle does not require both accessories for remote start.

probably too late, but all you need to hook up on the bypass (assuming it's a 556u) is power, ground, and status. if for whatever reason the car shutdown when trying to do the key takeover then hookup keysense. very few cars ever do though

Yeah, i already did the install, everything went well until the brain fried..gota go back tomorrow :(

For future if people look this thread up, don't try to go to the BCM, it's a bitch, get everything in the kick panel!

And the key sense wire is an GREEN/ orange in the ign harness.

how u fry the brain?

It just shorted out for no reason, I have had two Autostart products do that in the past week, never installation error, each time a new unit was plugged in and worked flawlessly.

However now I am having an issue, I picked up a key in the box type security bypass with the stick on ring antenna, but it will not work unless the ring is outside in front of the key cylinder, so im looking for a better type of bypass, is there any recommendations??

Also, where have you guys gotten the alarm disarm wires? I could not locate it.
