5th Gen 4Runner TRD Key Fob Case (AJT Design)


4Runner Key Fob Replacement and Upgrade for 5th Gen 4Runner

5th Gen 4Runner Key Fob Case (TRD Key Fob), Made by AJT Design

Wow. I was really thinking of another way to start this overview, but “wow” is all that came to mind. If you are looking for an upgraded key fob for your 4Runner, this should be high on the list of choices. The 5th Gen 4Runner Key Fob Case, made by AJT Design is a thing of beauty.

This key fob needs to be held, felt and caressed in person to really understand just how impressive it really is. For general 4Runner accessories, this is a favorite. I am blown away by the precision and perfection that is now encased on my 4Runner key.

The AJT Design 5th Gen 4Runner Key Fob Case comes in a wide variety of colors to match your 4Runner. Ranging from Cavalry Blue to Super White, you are sure to find your color in the AJT lineup. What is also pretty impressive about this key fob is that you can further customize it with different color hardware. With these 4Runner key fobs, you can customize your Top Color, Bottom Color, Button Color, and Screw Color. If you are looking for the exact color options, go check out the AJT Design Website for Color Options.

The AJT Design 4Runner key fob ships as a remote shell, not with the battery and transponder chip. You have a couple options for using the AJT Design 4Runner key fob. You can use the fob with the key blade or without the blade.

TRD Key Fob With Blade

If you want to use the AJT Design fob with your key blade, you need to essentially damage your OEM fob to get the blade out. You can either damage your OEM fob or buy a blank from Amazon or eBay. With a blank, you will need to have the key cut and then use that key blade.

The nice thing about buying a blank is that you don’t need to “damage your OEM key fob”. I say that with quotes because you still need to extract your transponder chip and this is a whole new task. It is possible to keep your OEM key fob intact and remove your transponder, but it will be very difficult. It was incredibly hard to remove the transponder without damaging the key fob.

If you use the key fob without your key blade, you still need to remove the transponder. This will ultimately require you to damage the OEM fob, unless you have precision cutting skills and the patience of a Munk. I was not able to keep the same structure of the OEM key fob when removing the transponder. The transponder is glued to the OEM fob and takes some effort in getting loose. See the installation instructions below. When using the key fob without the key blade, you will need to use your valet key to start your 4Runner.

The AJT Design key fob looks like a TRD add-on. Not only does it scream TRD design, it has TRD imprinted on the back. Again, incredibly impressed with the design and thought process that went into this product.

Quick Note: Do not use thread locker on these key fobs.

Swapping Out the 4Runner Key Fob with AJT Fob

Be patient. The process of extracting your transponder and key from your fob without damaging your key fob is tedious, to say the least. About 5 minutes of being gentle and trying not to damage anything, I gave up. I started cutting the key apart and tore all of the plastic from the fob away from the key blade and the transponder.

You can buy a blank from Amazon and damage that key fob to extract the key blade if you are looking to keep your OEM key fob and key blade together. But even this method does not prevent you from damaging your fob when removing the transponder. If you do purchase one of these key fobs, just plan on damaging your OEM key fob. You will need a utility knife (box cutter) to get the transponder out and to cut your fob away from your key blade.

The transponder is glued into a little housing on the OEM key fob. Gently work around the transponder chip with a utility knife or a tiny flathead screwdriver until you have loosened it on all sides. Work your magic with them and pull that transponder out when it is ready to come out. Try not to force it and damage your transponder chip.

Removing Key Blade & Transponder from 4Runner Key Fob

  1. Pop the Tab on your OEM Key Fob
  2. Use a fresh blade on your utility knife to cut the plastic away from your key blade
  3. Remove the key blade from the OEM fob
  4. Press your utility blade in between the transponder and sidewall of the transponder. Repeat this step all the way around the transponder. Try not to bend your utility blade or else the tip will break off between the transponder and the sidewall (like I did below).
  5. Once you have loosened the edges of the transponder, pry it out with a tiny flathead screwdriver. Do not force it. If the transponder is not coming out, keep working on it with your utility knife.
  6. Once you have your transponder out, start putting your new key fob back together.

    Hey man I’ve been having this dream to have a color matched keyfob. My 4Runner is a blizzard pearl. Wouldn’t you think it’d be much cooler if the colors were the same as your vehicle? thanks!

    • Brenan - Trail4R

      Yeah, color matched or not, these key fobs are pretty awesome!

      • Andre Abad

        Yes I agree these are awesome! Thanks!

    I saw this and was totally excited, but was looking more for a MOD for Flipkey conversion. Has anyone seen such or MOD or had success with such a MOD

    Hello- Would we be able to leave the Valet key in the ignition full time and utilize that to start the car with this new FOB/transponder left in my pocket? It’s been awhile since I had a car that actually needed a key inserted to start the motor. So question boils down to:

    1. Does the Valet Key have a transponder built in to it? If so, this would allow someone to drive off with the car. So I would cut a key without the transponder and leave it in the ignition.

    2. If not, I’ll just unlock the car with my hands in my pocket and start the car with the valet/recut key left in the ignition full time.

    3. With the New FOB in my pocket, would the transponder signal reach the steering wheel/ignition column to start the motor?


  • Adam Truckey

    1. Yes it does.
    2/3. The transponder does have to be pretty close to the ignition. I am not sure the exact distance but I am pretty sure your pocket is to far away. Thinking it has to be within about an inch. There should be a security light on your dash that turns off when the transponder is picked up so you could experiment with it.

    Hope this helps.
