Tundra key types H, G, regular

I searched but cannot find anything on this.

What is the difference on the H-key, G-Key, and regular key for a 2019 tundra. I have a '19 platinum with the FOB integrated into the key and am trying to get a good answer before purchasing remote start.

I have to assume the regular one has no FOB or security chip.

 

Look where the key blade meets the plastic fob. On one side there will be a letter engraved on the key. My 2018 SR5 has an H and I'm going to assume yours does too.

 

Yep! I noticed that not long after I posted this message. Thanks for your response.

 

G here

 

I have the 2019 CM 1794 and with the h-key

 

2018 sr5 cm, h

 

Mine is an "H". '19 Platinum.

 

<2018 : G
2018+: H

 

yeah makes sense G on my 2016 SR5 DC

 

This is the first I’m hearing about an fob integrated into the key head.
Is that a factory thing?
I’d love to do it so as to reduce the bulk of my keys.

 

My 15 is G

 

G here

 

My ‘11 is a G

 

Nearest I can tell, the 2018+ have the fob intergrated and uses an "H" chip, 2017- is separate and uses a "G" chip.

 

Has anybody attempted a retrofit of a <2018 to the "H" key? What makes it so difficult?

So can I buy this and have a 1 piece tundra key?

 

Man that would be awesome

 

From the link

 

Got half a mind to buy one and see if I can swap in an H key and chip.

 

So I had a discussion about this with the parts guy at my local dealership when I there for service on the wife’s 4Runner. Both G and H keys have chips that are needed to start the truck. G and H don’t interchange, but you can buy the G key from a 4Runner, get it cut, program it and you will have an all in 1 key/fob for your 14-17 truck. They dealer wanted like $375 to do this. You can probably buy a key on eBay then use tech stream for much less.

 

Ditto...

 

Nice!

 

Good to know about the 4Runner key!
But what is “tech stream”?

 

So are the key blanks the same, and the difference is the G vs H chip?

 

It's the toyota OEM software used to program their vehicles. Can be "obtained" for personal use through various means

 

As far as I know yes.

 

Awesome. Anybody tried one of these critters?
