So you are wondering if size matters... LOL!
What's really interesting is that the rest of a vehicle can be near-perfect. A person loves it or at least is satisfied with the vehicle. Then one little thing which really has no big impact in the grand scheme of things, it's annoying at best, but has no impact on the product usability as a truck, it's life, mpg, towing or payload, comfort while driving, HVAC, visibility in traffic, no other functionality, and that one not so little physically thing is worth pages.
Simple fix - bigger pockets - or, a holster, or cut/grind off the high portion of the button that trips the key so it can't be accidentally released in pocket.
All radios employ some type of antenna. The fob has three radios; one that's only sort of a radio. The pushbuttons operate a radio with a "large" radiating antenna that transmits in the range of 315 MHz. Like you, I've found that the JT has far greater range than the JK, so that leads me to believe it has a better antenna (which generally means larger, not strictly always). Then there's an active RFID radio which is what tells it exactly where the key is, and is used for the proximity stuff like unlocking and starting. It needs only a fairly short range, small antenna. There are antennas in various places in the vehicle so it can detect the fob location. The "sort of" radio is the one that lets you press the key to the start button and operate the ignition even if the fob battery is dead. It's passive RFID which means it gets power from a coil in the dash, and transmits using a stub antenna that is not tuned to the frequency, and technically does EM coupling to the receiver instead of radiated RF.
No, thank you, it's a slow day and I will enjoy this topic again. Remember that there's just one trolling lunatic who has already said things like the key is too big and heavy for him to add to his 55 pound pack when he hikes for three weeks at a time. He's running out of material.
So you must stay clear of the electromagnet lab at ISU that has all the huge warning plaques stating to stay away if you have any implants or electronic devices and so on. Yards away they start posting the warnings. Some folks I know would be pulled right up hard against the wall, unable to move.
You saw that my wife used my 04 WJ to help a friend finish moving and she said "I suppose I have to stick a key in it.......... and then "crap".
No, the implant is rated to a 3T MRI (being inside it). So proximity is no big deal. Also the issue as I understand it with most implants isn't that they'd be pulled, as most are non-magnetic. It's that they will heat up and burn you. In the 90s I accidentally walked into the back room of a 5T MRI with two PCs. They weren't pulled out of my hands, but were internally destroyed.
I had a science teacher who demonstrated the impact of fields on coils - shot a small aluminum ring into the ceiling and it was so hot you couldn't even come close to touching it, so I can imagine the impact. In his demonstration, the field created within the coil was opposite of the field exposed to it and it shot like a bullet! There was a BANG and it was GONE - all by an electromagnetic field.
Serious Question
The JT was rolled out with a lot of options. But not nearly as many as the JL. I imagine it is partly marketing - they can introduce additional options over several years to get owners to trade up.
The button sticks out - A LOT. It doesn't take much of a "push".
