Y164-PT Transponder Key


The Y164 key is not to be confused with the Y160 key, which was the earlier version. The best way to tell them apart is to look at the color variations in their heads. The Y160 is greener, while the Y164 is tanner. Many of the various manufacturers, on the other hand, have their interpretations of what tan looks like. Just looking at the picture below will give you a good reference point of a tan head and a gray head.

The Y164 used the Philips 46 encrypted, also known as the ID46, as its chip. Several car manufacturers use Philips' ID46 chip. Honda, Chrysler, Nissan, and Mitsubishi are all represented, but the chips are not interchangeable.

For the test key, you can use a standard Y159 key. It's a super popular Chrysler key, has a nice kind of more oversized head, and it's something you can use practicing before you start duplicating or originating the Y164 to make sure it works.

And the shell used is the TP00CHR-15.PC. It's the JMA part number for the key shell, but it's essential that you can take them out and replace them to put the chip in a new shell if you do miscut them. Meaning the JMA transponder keys can be easily pop out and replace.


The code series used is the M as in Mary, M1-M2618. There is a PDF with the list of all of the stuff, including the specs on the code series.


The machine I'll be using for duplicating the Y164 key is the JMA Nomad. It's going to be the Y159, the test key for it. And I'm going to use side one or side A.

What's going to happen? You put the key in the jaw on side one or A. Now, it sits on there really naturally. Okay, which is a great thing and is what we're doing is on this little ledge right here on this big groove on the key; that's where we're setting it. Alright. And as you can see, even with the cuts there, they're still what I like to call 'enough meat on the bone or enough material' to grip the key.

However, since this is a tip stop key, meaning there's no shoulder on this key at all, we're going to align it on the tip, make sure you can get as much of the key as possible on the jaw, so there's enough material to clamp to.

So, in other words, you have these two options. You have this option here to clamp it or this option here. If you use this option, as you can see here, it's a recipe for disaster.

That's not going to work, so make sure always to use the furthest option possible to clamp it down. Even sometimes, if I'm a little suspicious, I'll take to tip the small gauge, shortstop, and running into it on both sides, and that's going to give me max meat on the bone to the key.

But for this example, we'll go ahead and just back it off to the slot, like the image below. I'll go ahead and put the key in, and I'll hold it down. We'll clamp it nice and tight, just like that. Now, we'll go ahead and take our blank key, we'll stick it to the right jaw, and we'll do the same thing. Please put it in, and clamp it down. At this point, we're just going to go ahead and duplicate the key. Now, of course, you want to make sure to clamp the key tight by giving it a wiggle. From then, you can turn the machine on and cut the key on that one side.

Alright, so that one side is done. Before I always do the other, I like to turn it on and get rid of some of these little burrs. And we'll flip it over to the other side. Now the sides, it'd be a little trickier side to make sure you clamp it down nice and tight. Alright, you can always get in here and make sure it's going to stay.

When it comes to duplicating a double-sided key like this, there are cuts on both sides, and there are two kinds of schools of thought. Let me tell you what I think. So I guess if the key looks brand new and are not worn, duplicating just one side of the existing key on both sides of the new key is not a problem, but if you start seeing anywhere at all in the key, I recommend just flipping the key when you duplicate the other side. So that's kind of the philosophy I've developed. You may not want to do that, that's perfectly fine, but that's how I've always done it. So get that line back up here. Make sure it's nice and tight. We'll duplicate the other side. Now, one last thing I want to bring up when we're duplicating this key - so I'm going to put it on here, and instead of just following it along, I'm just going to shave off the top. I will shave it down a little bit, which will always prevent the key from moving around sliding and causing problems. So let's go ahead, turn it on, and cut this side.

What I've done now is I've halfway got the key, and I've eliminated any need to worry at this point about the key. Plop it up, so we're going to finish it.
