Because you left the Jeep running when you exited. He saw the warning message "Key fob has left the vehicle" on the center display, but the engine won't shut off when the fob leaves. If he had shut the engine off before you returned to the vehicle, however, he wouldn't have been able to restart it.

I paid for a year in advance; it's a little over $12.00 per month doing that.

Say the passenger had the key FOB, and left the vehicle while it was running in drive, with the drivers foot on the brake. He would be able to drive away. But then what would happen if he stopped a block away, and put it in park? Would he be able to put it back into drive without the key FOB in close proximity to the vehicle, even if the engine was left running?

Re: Using Remote Start Smart Phone App ?

Why don't you try that and let us all know?

+1 This is like a "valet" feature. The vehicle can be driven away and parked without the FOB inside, but once shut off, then the FOB in the vehicle is required to drive away again after UCONNECT or FOB restart.

I have a 2015 Jag F-Type S Coupe with a VALET setting. It turns off all touch screen features/selections, locks the boot (trunk) + glove box, and turns off the audio. Neat.

The vehicle will continue to be driven. You can put it in Park, reverse, or any other drive mode. What you can't do is restart it once you shut it down (without the key fob being present).

Jeep designed it this way so that if the battery dies in the key fob while driving, you don't get stranded.

If you remote start the vehicle from the app, then wait the (at least) 90 seconds to start itself then get in it. Turn the vehicle on. Now you can use the app in basically real time to lock and unlock the doors at will. It's under a second to shoot the electrons over the airwaves.

The problem why it takes SOOOO much time is poor coding. Before they screwed up the system trying to protect from hacking it was basically 90 seconds from app to start if you were parked in an area with good sprint coverage- you could almost set your watch by it. Now it's spotty and can take minutes longer.

The uconnect system has akin to a bunch of "modules" and the sequence it loads them is dumb. (order from memory so forgive me if wrong->) If you just get in and start from the ignition button, the first thing that loads is the super basic bit with the disclaimer and heated/vented seat controls. Then the radio loads. Then the presets load. Then the phone. Then the phone's phonebook. Then the phones messaging. Then navigation. Then the Sirius travelink apps. Then the other uconnect apps. Someone spoke to the techs at CES at the beginning of the year and they explained that the remote start feature loads all the way at the end with the "other apps".

So you hit the button on your phone and assuming good sprint coverage- the text to start the vehicle hits the modem in the car in under a second. But the whole stupid uconnect system has to boot so you're waiting 90 seconds for anything to happen.

If they ever fix the complete system to the pre-hack-"fix" efficiency then it will be 90 seconds. You can stand next to the vehicle at night and hit the button on the app and then you can watch the radio wake up and do it's thing through the window (the screen stays blank but you can see the radio wake up becasue the back light comes on, and if you have a USB drive plugged in you can see it's activity light go on).

Just poor engineering.

At CES before the hack they said they were going to try and tweak the system so that the remote start bits started earlier in the sequence but who knows if they'll ever bother now.

They could also learn how to put the system in a low power sleep/standy/whatever mode. But that sounds too advanced for them.

Incidentally the hackers wrote a pretty cool report of the system and how to hack it (someone posted the link someplace in here..) . One tidbit is the v850 chipset which does all the can bus communication does go into a quick wake low power mode. As above, we know the modem is always on too as it wakes the main uconnect system on a chip. So if they could figure out how to SECURELY allow the modem to talk straight to the v850 chip it would be basically instant for teh remote keyfob functions. But at this point that seems impossible.

Also seems they have abandoned 2013, 2014 and 2015 MY customers and will only add new stuff to 16's. (hopefully that's wrong but some have been told by customer service- no soup for you)

Re: Using Remote Start Smart Phone App ?

The dashboard on mine lights up pretty quickly after I give the app the command to start, (pressing in the 4 digit code). I would say within a few seconds. But then the whole process drags on for over 2 minutes+, until it finally starts.

Re: Using Remote Start Smart Phone App ?

You would think they could store all those codes with battery backup, so they don't have to "load" every time you turn the car on??
