Which key blank and remote for 2008 Tundra?

NOTE: I HAVE MY OWN KEY CUTTING MACHINE/JIG. I do not need help from a locksmith or the dealership to "cut my ebay key"

I've cut keys before, I simply need to know which key these 2008 Tundras use. I'm pretty sure I've found the model# code to be "TOY44D-PT" but I'm not sure.

Also, every listing specifically mentions "Make sure your key has the dot on it"
My key does have the dot, but I'm not sure what it means. Does the dot correspond to the key having a transponder?

I plan on getting Techstream installed on my computer, but have not used it yet. How does key programming work? I've done it for Volkswagens (which is very well documented online), but I can't find any sort of walkthrough or directions for Toyotas.
Not sure if programming needs to be done via laptop & Techstream, or if these is one of the cars where you can do it like "lock/unlock driver's 17 times, put key in ignition, turn key on, key off, key on, etc etc"

Also, is it possible to use an all-in-one key for this truck? Key and remote in the same unit? Like a 2012 Camry?

Here's my cutting my VW keys:

 

I got my blanks from Amazon (wife has a prime account). The ones I got had the Toyota logo on them. I don't have a key cutting machine but just went to my local hardware store who cut them for free. I got the remotes from ebay and were just the cheap generic ones.

I used TechStream to program them. It's pretty straight forward but you will need a key that has already been programed to do a new key. If you are handy with a computer then you can figure it out. I found getting TechStream to work correctly with the cable was more difficult. Your best bet is to get the blanks/ FOBs and TechStream and then ask any questions. I haven't had the need to do it again, if I do I figure a "how to" would make for a good sticky for the top of the forum.

 

Thank you for this reply.
I FINALLY got Techstream to work!
I think... I got Version 12.blah blah but it seems pretty primitive and slow.
This is my comparison from Volkswagen's version (VCDS). Even 15 years ago that thing was pretty quick and offered live, real-time data streaming.

I'll see what it can't do when the new key comes in the mail.
Thanks for the link for the remotes as well.

 

Getting the clone cable to work correctly seams to always be an issue. I think the software was written to work with dedicated computer equipment used by Toyota's mechanics (usually known as an SST). I haven't explored it much but I have seen more than one service bulletin that uses it to diagnose problems. For example on the '07 and '08 Tundras the torque converter has an issue when it locks the clutch disk. The procedure has the tech bring up a graph to identify when it's happening as well as monitoring the trans computer to see which valves are open and closed. Most people buy a cheap cable to connect to the OBD2 port that connects to the USB port on a laptop. The slowest thing I've noticed is when it's downloading data from the ECU and sub computers. Is it just slow, the USB connection, or is there a lot of data being transferred that you don't realize?

Toyota does offer paid subscription to their data base that includes digital manuals and their software for anyone (mainly mechanics). I believe they offer a very limited (a couple day offer) for those who just have one issue they are stumped on. Others have posted where they sign up and download everything they possibly could want during that time.
