Charging key fob idea

I have been hoping that the key fob incorporates a rechargeable battery. However, I was also thinking that it would be cool if there was a dock inside the car so that you could charge the key fob while you were driving!

I don't actually expect this, as it might ruin some of the aesthetic, and, it seems like one of their sort of 'wow' features, is that the key/ignition system will be completely contactless: from the Features page, "With [the key fob] in your pocket, Model S turns on as you buckle in to the driver’s seat."

I can't argue that's not pretty freaking cool, but for practicality's sake, I would actually prefer to have a docking key fob that charged while docked. -Just a thought-

It would be cool when you could have the information from your Tesla-app on the fob..

Sorry, but it would be much cooler if the battery is guaranteed to last at least a year and the car notifies you when replacement is due. It would be like smoke alarm batteries. You just replace it on a regular schedule.

What I would prefer even more is that your smartphone could act as the keyfob so I don't have to carry another thing in my pockets. Use the wifi address as my ID. I love elimination/consolidation of crap I carry every day. If it is RF-ID, another option would be a flat key RFID tag like I have for work that I could put in my wallet.

Don't get me wrong, the keyfob is sexy, but no keyfob is sexier.

@Leofingal: Agreed.

@Leofingal
+ 1 to a no key fob wallet card solution. I hate having keys in my pocket!

@LeoFingal: +1 Agreed.

@Leofingal

+1 no keyfob is best. How about voice recognition?? Now that would be cool.

I want HAL from 2001: A Space Odyssey. LOL just without the psycho bits unless it's a car thief.

I like the key. I would place it in the space (where no console is) provided.

Thief: Hello, HAL. Do you read me, HAL?
HAL: Affirmative. I read you.
Thief: Open the car door, HAL.
HAL: I'm sorry. I'm afraid I can't do that.
Thief: What's the problem?
HAL: I think you know what the problem is just as well as I do.
Thief: What are you talking about, HAL?
...

Just reading this I'm realizing this is another habit of mine that will need to change when I finally get the car. I already leave mailbox and front door keys on my car keyring for ease of use and many times leave my wallet in the car or in my backpack.

What will I do with a key fob? If it is too big it'll be a hassle. If small then I'll want to put it on a keyring, which will work with my habits. But if it doesn't allow keyring then it'll be this key-sized thing that acts like a key but doesn't go with the other keys.

A wallet card shifts my habits in a generally good way (will always have my ID with me when I drive) so that's a good solution.

My list of changes from getting this car:
- will tell car to heat/cool itself 10m before entering it
- never visit another gas station (I can even air the tires at home)
- CDs won't ever leave the house, mix lists will be MP3 compatible or stay on the iPhone
- will need to set aside time to give folks test rides and talk about the car
- will need to store my keys differently

Mine will need to come with a tracking device. I'm always putting down things and forgetting where I put them. More than once I've had to retrieve my phone or credit card from security and I've lost my badge twice. Don't know what I'd do if I lost my key fob. Hope they give us a spare that I can keep at home.

My Mercedes key fob is huge! Only a woman with a purse would put it on a key ring. As a guy with regular size pockets, I keep the fob separate in my pocket.

The nice thing about the Model S fob, like other more recent cars than my Merc, the fob can stay in your pocket. So it just gets tucked down at the bottom of the pocket and stays there.

Of course, if you don't buy the tech package, then you'll need to reach in your pocket and press a button to unlock the car.

ZipCar has an iPhone Unlock that the tesla could do.

The iPhone works as the interface to push a button to unlock.

I like the ability of a proximity unlock that the FOB can provide... I don't want to take my phone out to unlock the car every time.

But the RF-ID would possibly be able to unlock with proximity, just close to the door.

Sorry... here is the movie of the car unlocking with an iPhone app.

I love the idea of my smartphone being my key! It would be even cooler if for safety's sake, if you happened to lose your phone, you could go to a website and disable that ability tied to your phone and assign it to a new Mac Address on another phone. Taking it even one step further... if you could temporarily assign that privilege to another mac address then you could give a family member or friend temporary access to your car without having to worry about getting a key to him or her. Then you could disable it thereafter.

I vote for the smart phone being my key. Otherwise, I will buy a thick gold chain and hang it around my neck- the ultimate status jewelry!

Petero, that sounds like a good solution for me too. I like it!

+1 for crap reduction. No fob is best.

You can get the full functionality of proximity unlock with an iPhone app that uses Bluetooth. You don't need NFC or a fob.

Every iPhone and Android has a Bluetooth link, which can communicate up to 70 feet from your car.

For those few times you don't have your phone, the best backup is a code pad.

Without any changes to the Model S design, TM can add a small printed keypad decal with a capacitive touch sensor microchip for about $2 cost. This can be adhered inside the windshield glass, in the lower corner near the driver's door. It can graphically blend-in so you'd only see it when you were looking for it.

Tap in the unlock code through the glass to get in, and a secondary challenge question on the interior touchscreen to start up.

At this point, carrying a lumpy fob in your pocket is absurd. It costs TM much more to have the fob, and this wastes money.

Save money. Simplify lives, and make people happy.

Increase margins too, by charging for the proximity app (which has no marginal cost).

There is so much avant garde thinking in this car, this fob is the curious anachronism.

You know all cars will support this eventually, so why not lead the way TM?

In a culture built on excellence in design (like TM), deciding this stuff is easy. You ask "Will the customer have a better experience?" If the answer is yes, and it saves money too, you do it.

Go for it TM.

The iPhone idea is really cool. However how would that go with the tech package?

How they sell it is a TM decision. They could make it part of the tech package, or sell it a la carte.

That's a business decision, and TM can ponder the best way to manage their margins while satisfying the largest swath of customers.

But either way, the technical implementation is a straight shot.

As much as I like the Tesla key fob -- I'd definitely want one to show it off on occasion! -- I'm all for "crap reduction". RFID-Card would be one way to go, but the reduction could go even further: I'd like to have RFID stickers come with my car, which I can stick on one of the cards that I carry around, anyway. Or on your phone or whatever it is that you have in your pocket.

DriveNow (and some other car sharing providers) work with this kind of "key". They stick it to your license and it is designed such that it gets destroyed when you try to remove it. That way they ensure that you have your license with you when you open one of their cars. Provided that I have a bunch of replacement stickers ready, I can see some value in that, too. If you want your son to be able to use the car, but not lose the key or give it to his buddy, simply stick it onto something that he needs to have with him, anyway.

There are security problems with RFID -chips, they are a bit too easy to crack. Not that it is a huge problem, but it is a problem anyway. You could use RFID with a key to send a message to car to notice that there is a key nearby which then activates a more secure transaction between key and a car to give car proper secure ID that that key is actually the key that has right ID to open the door of the car. However that is no longer a teeny weeny practically invisible tag in a sticker.

Because of high value of the Tesla cars I would be a bit concerned about security of it if RFID-chip itself is the only ID it needs.

Guys, people get confused by all the flavors of code technology. RFID, NFC, Tesla fob transponders.

But they are all simply containers for numbers. Numbers that you have, and the thief doesn't.

With nothing more than numbers, I wire millions of dollars online. Properly set up, it's plenty safe.

You don't need any physical item to have the numbers, just knowledge.

With your computerized car of the future, you want the peace of mind that if you lost your wallet, keys and everything but you swim trunks, you could get into your car and start it when needed.

We are not talking about a 4 digit PIN either. You can make those numbers (or passwords) as long as you like to have more anti-theft security. Choosing the password(s), and the quantity of inside and outside safety layers is up to you. That's easy to make as a configuration option for the user.

The reason you want the iPhone app is for convenience. It can remember your numbers securely, and it can serve them up automatically when you approach your car, so that in normal use, you don't even think about those numbers. You just get in and go.

And you don't have to carry any more crap.

A car remote fob is nothing more than an radio transceiver and a microcomputer containing numbers and rolling-code algorithms. All of that can be done just as well with the Bluetooth radio and the computer in your iPhone. It has all the same functionality, and then some.

I believe the hybrid of an iPhone Bluetooth app and the thru-glass backup touchpad is the best solution.

Max Securtiy + Lowest Part Cost + Highest Convenience + Least Crap = Happiest Customer

@Liz G | February 26, 2012

Perhaps you could have yourself "chipped", like a pet, so that anytime you're near the car it opens -- or asks for a voice ID. ;)

@Mark K

...
And you don't have to carry any more crap.

...except that iPhone. You always need to carry some sort of hardware, at least until cars get smart enough to actually recognize their drivers from their looks. At that point crazy HAL -scenarios are not too far behind.

Also iPhone just like any other cellphone can be stolen or lost just as easily as keys, if not easier, and it can run out of charge which would cause you to wait until it recharges before driving. I'd prefer small RFID -like systems that gets its power from the scanner.

@Brian H

Demolition man, anyone? Retinal scans, deep scanning vascular system pattern ID with body heat sensors (no dead tissues allowed). Something like that. You touch the car and it knows that it is you.

Mark K: How would you allow other drivers with the fobless system? You can give the passcode to your significant other but what about the parking attendant? Would you keep a set of numbers for each? I guess The number for the parking guy would also be associated with a restricted power setting ... but I doubt that giving the valet service guy a paper with a code would be feasible in the real world.

@Brian H

Knowing me I'd find someway to lose it. :-)

Hopefully not a huge fob. The ford explorer fob seems to run about 6 years before the battery runs out. Could not say, that's the longest I've managed to hang on to it. Rechargable, probably not a great concern.

I just assume I'll have a retnal scanner for valet service.
