Bluetooth Low Energy (BLE) devices won't show up in your phone's BT pairing area. The idea with BLE is that they are more like "instant connect" devices that don't need to be paired ahead of time. There will some sort of "sync" procedure so your fob doesn't connect to just any car, and you car doesn't connect to just any fob, but don't look to your phone to see these devices.

If you're really curious, search for "BLE Utility" apps or Bluefruit LE to scan for local BLE devices.

Less complex system. Tesla took the design in-house over the original RF system that was outsourced to a British company called Pektron. In theory it could have better battery life. (In addition to the lower cost)

And yes, if Tesla wants to write the software for it, a smartphone could stand in for a fob in the BLE system.

Well I popped mine open and compared the fob model number to the one of the FCC website. Mine is a 1043xxx and the one the FCC website is a 1048xxx so I suspect my one week old Model S has the old fob.:(


Nothing quite like 4 day old dated technology.

Quick someone respond about waiting for the best version of a $400 Iphone.
