Hey, so theres a a couple DIYs but most are either partial/incomplete or lack the proper pictures. DO THESE ARE YOUR OWN RISK GETTING A KEY REPROGRAMMED FROM THE DEALER CAN BE COSTLY IF YOU MESS UP

Essentially the goal was to make a switchblade key for cheap. Let me just state something about this DIY so you do not make the same mistake as me:

DO NOT TRUST THE KEY BLADES FROM ASIA ALL THE ONES I WERE SENT DID NOT WORK IN THE CAR! BUY AT YOUR OWN RISK

CAREFUL OF SELLERS WHO SAY THEY WILL CUT AND PROGRAM YOUR KEY I will touch on them later but the only company I would trust is HeelToe Automotive and their key conversion services.

Things you need:
OEM TL-S Key Fob FCC ID: OUCG8D
OEM Key and Copy of OEM key
Tiny phillips screw driver (micro sized)
JB Kwik Weld
JB Putty (optional)
Dremel
Drill
Sandpaper (coarse and smooth grit) (optional)

Costs:
TL-S Fob: $35
RDX Plate: $10
Key Copy: $4.00
Spare Parts: $14.00
Materials: $8.00
Total: $71.00

eBay fob: $55.00
extra blades (3): $50.00
extra H shell: $30.00
Total: $135.00

DIY Cost: $206.00
Actual Cost (shipping, etc.): Close to $280.00

Ill detail later how the eBay route was not cost effective and ended up costing this project more than I intended.

That being said: if you get an eBay fob, you can program the board to the car but the easiest method is to either get a spare cut to the car or cut up your OEM one.. I did both. The only easy way out is to go through Heeltoe and pay the price to get one made but I will touch on them later.

So what you need: OEM TL-S Switchblade key or eBay flip key

(The TL has the RDX plate to delete the trunk button)

eBay fob has a different button layout but works. Everything about it is oem in size and build. Theres a little modification needed to mix OEM with eBay and vice versa.



Unscrew and disassemble the fob. There will be a total of 4 screws, a torsion spring, button and spring and the swivel and key with the plate. Dont lose anything but you can find replacement screws at an Ace hardware (tiny machine screws)

Take out the key and you will proceed to take out the metal half circle track guide and the transponder. Chances are your FOB has never been taken apart so theres 3M tape holding things in place so you will have to use some force (you may have to drill out the old transponder chip from the TL fob)


Now you can begin to cutting the old key out.

Dremel away the bottom of the swivel until the entire key can seen
THE LESS THE BETTER! Ill make a second post of why the original method doesnt work as well.



Drill out the 4 holes in the key that keep it in place (it makes it easier for the key to pop out)



Now you have a template for your key to cut to shape! This is a copy of my OEM one

I traced mine with tape and cut and then rubber banded the two together and just cleaned it up. I found going a little smaller with the template helps when you glue it inside.

Here is my OEM key I cut, theres a gap in the middle of the OEM key and so you can make a perfect cut but its okay.


I found using the JB Kwik Weld works the best. Make sure you key fits flat and snug into the swivel. The plastic flexes a bit so mine I have to work its way in and it had no wiggle. This is the goal to keep everything tight and not risk it breaking.


I put some JB Kwik in the slot and pressed the key in, you want excess to come THROUGH the little holes you drilled earlier. This will help keep it all solid and in place.

As the JB kwik is settling, you can use extra and build back the swivel you cut away. It wont be perfect, but you just need the excess to go a little around the edge to cement it in place. By a little I am talking a Millimeter or two. There isnt much room to play but you can sand away to make it flip freely.


Let it dry, it takes 24 hours to cure fully but after half an hour or so it should be dry enough to test in the fob. You want it to lock without poking out the side and lock sitting straight up. If theres too much weld depending how dry it is, you can use an exacto knife and cut some off or sand it down, just make sure its flat!

For me, my first key was too long and it angled upward wouldnt come out of the fob, I had to cut a notch out of the bottom corner and side for it to clear and now works flawlessly.




I dont have any pictures but I did use the JB Weld Putty to fill in some grooves and clean up the swivel. I sanded it down and used NHBP touch up paint I had laying around to give it some of that shine again.

Finally, it is time to place the immobilizer chip into the fob.


It goes where the old one was, it should fit without modding the hole but the cover wont fit over it. you can drill out to make it longer and work, I am awaiting to be 100% done and positive I dont need to do anything else to these keys before I do something like hot glue them in but because the key closes as long as they sit snug inside it wont go anywhere.


Let everything dry and you can move on to testing the key

I am ordering a TL board for my RDX key but the other is the TL-S.


The "H" emblem fob is from an eBay fob but I put the TL board on top. Honda does NOT officially make a flip key for the vehicles.
**Before you ask for one, I have contacted the seller after finally getting one on the way and they have yet to respond to me..**


My goal was to have a H flip key to match my emblems on my car and an Acura one to remain as OEM as I could so I had 2 keys along with a backup spare.

HUGE THANKS to the guys at HeelToe Automotive, while they make a key, cut and chip swapped for your car for around 170 bucks. I told them my situation and they hooked me up with all the spare parts I needed as well as some extra goodies. If you check out their site (https://www.heeltoeauto.com/now-offering-spare-parts-for-fastline-switchblade-honda-acura-keys.html) they offer any spare parts in case you mess up your DIY.

For you guys out there willing to pay to play, seek them out. Excellent Customer Service and they will work with you to meet your needs!

I must advise, you will spend the same if not more if you go the eBay key route because the hardest part is finding a pre-molded key blade for our car in the swivel.

The keysmith and I examined the eBay with the OEM key and we found the middle groove is literally a hair wider than ours and the thickness is a hair thicker, this is just enough to stop the key from turning in our locks. I went through 3 eBay blanks out of 5 before I decided to go with a OEM and a copy. I wasted too much money and time trying to get it to work so don't make the same mistake as I.

I found you can buy new TL-S Button and boards from Honda for about $35 bucks. This is the last thing I need to have 2 working fobs.

If you have any questions, post them here and I will stay on top and answer what I can to the best of my abilities.

The next post will detail the "traditional" way people did it in a way that I first tried doing the DIY and it didn't workout as well.

I found a DIY on this for the TSX and the method I found was most common was cutting the key out by halving the swivel piece.

By cutting along the thicker side against the key, you can put the new key in between and I JB Putty the two together. While this sandwich method worked at keeping the key together and I used it for about 2 weeks, it required ALOT of modding, sanding and rebuilding the locking notches to hold the key in place.

After it dried up I sanded the edges down and used the touchup paint to cover it up.


Everything worked well but then I realized when I closed it, it wouldnt close all the way and was getting caught up in my jacket and pockets and stuff.


It progressively got worse, here are pictures comparing the two:

I had to use putty in the edge, put the key in and push it in to "mold" the lock notch. While this worked a bit, continued use wore the putty down and eventually would round the lip and the key would slip again.

My method keeps the lock notch intact and therefore no issues looking in place.

This DIY is the one I used to go at this mod. If you go to the bottom you can see how he combated it. I tried and it worked a bit but ultimately that too failed.

Heres some parts and numbers for what you need:

Entire TL-S Fob New: 35111SEP306 $75
TL-S Board and Buttons: 72147SEPA21 $30
Bottom Assembly and Key: 35119SEP305 $35
3 Button & Panic Button Cover: 35118STXA11 $12

You can get the RDX plate from Heeltoe after shipping for about 15 bucks brand new.
You can get the RSX key blank in a swivel from heeltoe as well, I would contact them about pricing and getting it cut.

**I got my first blank cut at Ace hardware and had to remove the blade from the fob
**I got my other 2 blanks cut at a local key smith and had to remove the blade they both noted that their machines had a hard time holding onto the key. Heeltoe has a cutting service with insurance incase it fails but from my experience I dont think they have that issue much!

Here is an update of my work:
Ordered a TL-S fob (Memory 2 that no one uses so it was virtually brand new)
Honda Accord Remote (17 bucks off ebay, slightly used)
TL-S fob board (to replace my worn buttons on my other remote)

Since our car can have 3 programmable FOBs I decided to do Type-Spaz's Honda remote DIY as my 3rd and final key conversion. I wont be doing a red emblem back mainly because I dont have the red emblems to match.
Sourced from my friend some OEM copies and programmed chips of my keys.


I decided to hack open a new one for the accord key remote and realized that the chips are all different.. my first one and one I made for my friend were little capsules but these are the new boards. No problem though, everything fit perfectly (and better than the capsules)


Following Spaz's DIY I took out the old key and cut and put in the new one, even cut two notches to really secure it into the half of the fob because the screwhole becomes useless with this mod and that really holes the fob together.


Let the JB Weld harden and then sit for about 30 minutes


I lucked out because I used just enough JB Kwik Weld to still allow the two halfs to close without having to shave or sand anything off the top. but I put a line of superglue on top and closed it in and added a drop of superglue into the key hole just for extra strength.


It will be a bitch to open again in the future for a battery change but this is the key I dont really plan on using often.

So now I have 3 keys:
OEM TL-S Acura Switchblade
OEM TL-S w/ eBay Honda backplate Switchblade
OEM Honda Accord Remote





I can finally bring my key conversions to an end.
I have 1 OEM Key and chip as last resort should anything break or fail which I am confident won't happen..
I have 1 OEM key with no chip (in the TL-S key with a copy of a blank I made a few months ago)
2 OEM RSX Fobs
2 TL-S Fobs that can be modified for any future conversions.



If you have any questions as always feel free to ask..
