Agreed. I read @Bills2ndJeep response several times and couldn't figure out what he was trying to convey. I figured there must have been some backstory that I missed.
Same here. it was the introduction of a crashed vehicle into the story that lost me.

i was in the Top of the Mark and couldn't remember for certain locking the vehicle. since i was near the window, i pushed the button on the fob in my pocket and could see the lights flash.

the Top of the Mark is on the 19th floor of the Mark Hopkins Hotel on Nob Hill. ?


I've been able to lock my car doors from 3/10ths a mile away. I was hiked up a hill and was curious if I my fob could make sure my door was locked. It took > a second to hear the honk after clicking the lock twice.

Looking back at it, that math adds up. 3/10th's of a mile is ~1.5K ft. Sound travels at ~1K ft/sec.

I've noticed battery power and LOS matter a lot with keyfobs. Advantage yourself with both and you can get some pretty long ranges.

Yeah the distance can vary for sure.

The manual has its range @ 66ft/20m for lock/unlocking/tailgate and 328ft/100m for remote start.

I knoI have very good range with mine(JT).

Explain please
ok, I don't have power door locks or power windows on my JL, and it didn't come with remote start or an alarm. I had an aftermarket Viper alarm and remote start added. The alarm and remote start have a their own, smaller, fob so I didn't want to carry 2 fobs. I took a blade from one of the factory fobs and fixed a key chain thingy to it for leverage to open the door. The factory fob just stays in my pocket. The whole point of this explanation is that because of keyless start, if I'm anywhere out of my Wrangler, but close enough for the factory fob to be in range to activate keyless start, bye-bye Jeep.

Sorry, I work in Chicago and it seems that almost every stolen vehicle get in a crash soon after the thief shoots someone from the stolen vehicle!

Ok, out of all that I understand the key chain thingy for leverage to open the door, but, of course, why TF would you need a key chain thingy for leverage to open the door??

Because my JL does not have power door locks?

Oh, so the leverage isn't (as you said) to open the door, but to unlock it? The locks are really that tight? Holy crap.

But overall it still doesn't make sense. If you have neither factory remote start nor factory power door looks then how does the having the factory fob in your pocket put your Jeep at risk? Maybe it's because of the Viper remote start and unrelated to the factory fob? Maybe @SargeDiesel understands this better than I do?

Kinda still trying to figure it out.

Im thinking he thinks:
1. If he starts his jeep with the AFTERMARKET remote start.
2. That if he is close enough for his OEM fob to be within operating range of the jeep.
3. Someone would be able to get in and start it.

I'm not so sure that could happen.
1. First how is anyone going to get in ? No power locks ?
2. I believe remote start is disabled if the doors are opened without the use of a in range fob.(pressing the button) he doesn't have proximity).
3. I think he needs to get a buddy and test his concerns... hopefully if he did, he would be put at ease.

Except...aftermarket remote starters require power locks - just like the OEM ones..

IDK... I've had viper alarms in the past (think 80's/90's)... but honestly I don't know exactly how the current models work. He stated that he DOESN'T have power locks or proximity so ?.
*But from my reading, I have found many references to Remote Start being on a seperate system than the power door locks, so the consensus was that REMOTE START WILL WORK with manual locks... many stated that they have it setup this way.
I'm not an expert... just what I read.
So
I say, KISS... keep it stupid simple. If he carried his OEM fob in a FARADAY pouch, he could use his aftermarket Viper fob to start the vehicle without having to worry about someone hijacking his jeep.
Honestly though, I think his scenario is a mute point, because I don't think it could happen...
I haven't tested this, it's just my gut.

The blade itself is is barely longer that what sticks out of the factory fob so no way could you turn the door lock without a thumb-thingy attached to the blade, just like every other key for any other lock. SOOooooo, because the factory fob has extended range (which is where this whole thread started), if someone enters my JL, or any vehicle with a fob that allows the vehicle to start by pushing a button on the dashboard, I could be inside of a store and all they would have to do to steal my vehicle is bust a window, enter, then push the button and away they go. With my Jeep. And to the person so said that the message would appear "the fob has left the vehicle", so what?
It's running. It just won't re-start when the fob is out of range.

you thinking too much. It's not about me remotely starting the vehicle with my aftermarket fob. I never should have mentioned the F'N aftermarket fob. The factory fob, in my pocket, inside some store or down the block from wherever I parked the Jeep, can allow the Jeep to start by pushing a button.
Where do all you people live, remote Montana? I'm in the Chicago metro area. Cars, Jeeps, trucks, hearses, hell, police squad cars get broken into every day. Pop out a window, easy peasy. Now push the big button on the dash and you gone.

actually, the factory fob needs to be in very close proximity to the center console for the J**p to start.

if i have the fob in my pocket while i’m standing outside and reach in to try to start it, i get a “Keyfob not detected” message.
remote start works a long ways off, but key-fob needs to be inside the vehicle for it to start.

Not trying to start a pee-pee contest... but your not thinking enough or not listening/understanding the advice given.

It just doesn't work that way .

The distance to use remote start and using the fob to authenticate a start are different.

You can remote start from a decent distance... but to actually bypass the security and do a hard start the fob has to be much closer.

*So you can see for yourself:

Try this.... take a buddy.... go to the biggest parking lot available or open space... remote start... YOU STAY at one end with you're fob and place your helper by the vehicle... see if he can "push the big red button and go".

It won't happen...

Even if you window gets busted... when they press the brake... the engine will die.

Not sure what else to say... take it or leave it.

*note: my statements are validated atleast with a 2022 JTRD, YMMV...
