NI01T/NI02T Transponder Key: Don't Leave Customers Stranded!

What is the difference between the Nissan Transponder Keys, the NI01T, and the NI02T? A general question, and if you're new to transponder key programming or automotive key programming in general, chances are, one place or another, you've seen these part numbers. So here are some information and details that will fill your questions about the Nissan Transponder Keys NI01T and NI02T.

All of this information is compiled into a PDF document for quick reference in the notes below. Make sure you check that out.


There is one difference between the Nissan Transponder Keys, NI01T, and NI02T, and as you can see, it is the head shape. The blades are the same; the chips are the same; the only difference is the head shape.

When it comes to ordering, you can pick one and stick with the NI02T head. For whatever reason, it is more popular. So, from now on, I'll refer to these two keys as the NI02T. These transponder keys were used for about 1999, up until about 2006, a decent year range.

For the chip, it's going to be using a Texas Instruments Encrypted 4D-60. It is an encrypted chip, and it is reusable. Meaning, you can reprogram the chip to another vehicle, but there is a limit to how many times it can be reused. The information is a little murky so keep that in mind.


Use the DA34 blank as a test key. It is a blank for the older model with the same keyway profile as the N104T, the transponder that came after the N102T.

I recommend the JMA Chipless keys; they're high quality, have been around a while, and you know that they work and don't fall apart. But if you want to reduce inventory and cover the maximum amount of coverage with as few partners as possible, you can use the NI04 Chipless key part number TP00DAT-15.P3 since the NI01, NI02, and NI04 use the same profile. If you do so, the head will be a little different because it has double the volume as the NI02T.


The code series is the 1-22185, the same code series as the NI04.


Since it is the same as duplicating a NI04T key, I will be using the DA34 test key.

As you can see, anytime a key has these big grooves in here as this one does, I typically like to bring it over to the jaw C or jaw three. However, it doesn't work very well because of the depth of the cuts depending on your machine.

As you get it on the groove, the cuts obviously must stick up higher than the key, and I find it kind of problematic using jaw 3. So you want to check if you can use it, but for the most part, stick to the jaw 1 or A, depending on your machine manufacturer.

Typically, I'm going to get my tiny spacebar, and I'm going to put it in the furthest one, but this key does not have a shoulder stop alignment, so it's going to be a tip stop alignment. And typically, you'd go ahead and put the key in just like this; however, I do not like to do it this way, and let me tell you why.

That's because when you put it on the machine on the jaw, there's not a lot of material for the jaw to grasp on, which can cause you problems.

So what I will do is use the same bar and hold it at the end; put the key in, and make sure you have everything centered or aligned. Do the same thing to the other side (right).

So by doing this, we're gripping all of this good meat right here and then, you know, we also have a little grip over here. This will prevent the key from flipping out of the jaw while duplicating.


Make sure that everything is tightened down; time to duplicate all the way to the tip.

Once finished, flip the key over, get it nice and tight, then duplicate the other side.

Put a slight buff on, and that'll be done.
