Are the KM100 and KM100(X) different tools?

No. Autel states KM100 = KM100X = KM100E. Both listings describe the same 5.5-inch Android tablet with 2GB RAM, 64GB storage, a 4950mAh battery and 2 universal keys.

Which is better for a locksmith doing mobile work?

Either one. Both weigh 352.7 g, run about 8 hours on the 4950mAh battery and use a wireless VCI, so you can work at the car without a cable. The (X) listing is the one that names the V200 VCI and Bluetooth 5.0.

Is the KM100(X) worth $27 more?

Only for the clearer listing and the stronger rating. The hardware is the same. The (X) page states free lifetime updates, the V200 VCI and the NASTF credential rule; the KM100 page does not.

Can either one make a key in 60 seconds?

Yes, with Autel IKEY universal smart keys. Both cover 700+ models and IMMO learning via OBD for over 90% of vehicles. Neither supports all-key-lost on Toyota and Ford.

Do I need NASTF credentials?

In North America, yes for all-key-lost and anti-theft part replacement. Key addition does not require them. The (X) listing states this; the KM100 listing does not.

Which has better brand coverage?

The same coverage on paper: BMW, Volkswagen, Toyota, Honda and GM among 700+ models. One KM100 shopper reports missing Perodua, Proton and Wigo menus, so check your makes before buying.
