Not quite. Althought on the TMax they don't supply a spare smart key, they do supply a spare manual key with a number card. You are right that the emergency procedure requires the m-key but if you have lost the s-key (or its battery is dead or it otherwise fails to work for any reason) you should still have the spare m-key and number card somewhere. Both of those are required to operate the es procedure.
You will also need the manual book with you, or on your phone maybe, because as you say the procedure is very complicated and you will never remember it if you just read it once months ago perhaps. What I've done is made a photocopy of the pages with the es procedure and carry it permanently on the bike. But I don't carry the spare m-key and number card with me so it would be an embuggerance if the s-key is lost miles from home, which sod's law predicts would be the case.
What will then cost money is to obtain a new s-key if it was lost but at least you will be able to use the bike meanwhile and it isn't useless without it provided you can find the spare m-key and number. Yam recommend in the manual that you make a note of the number on the card so that you don't need to have it with you to operate the es procedure. You will still need the m-key of course but most of us will keep that at home cos we don't want to risk losing that too, so it will still be a problem if we're miles away.
For the ultra cautious rider, (and I'm not one) the ultimate answer is to get a copy made of the spare m-key, which may not cost very much, and carry that with you at all times together with a note of the number and the es instructions. That way if you lose the s-key or it fails to work, you will always be able to es the bike wherever you are, and still have the original spare m-key and number card at home just in case you manage to lose both the s-key and the m-key you carry with you.
