Replacement Key Fob Case fit for Hyundai Sonata Santa Fe Flip Key Remote Control Key Fob Shell

Add me to the list of people who had difficulty, but ultimately I "learned" on the first purchase of this product and will likely buy again because the price is great and the product should work well now that I've experimented with the first one. Here is what I found...After reading several reviews I figured people had issue with the old key not quite fitting the new fob just weren't doing something right. Stupid me. I took the old fob apart transferred the chip and the key to the new (my old fob didn't have a transponder? maybe they don't all have one?) and lo and behold the key would not flip out. Many have said that the old key is bigger than the new key, but that is not really the issue. More in a moment on what the issue actually is.Since I didn't want a remote that the key didn't flip out properly I finally decided to do what many others have done and just replace only the silicone button cover (the part that was worn out on the old fob) popping it off the new fob and putting it on the old fob. Contrary to what many have said, I found this process very difficult and frustrating.I did discover that what holds the silicone and trim ring in place is that on the inside of the silicone perimeter there is a very small ridge that engages with a very small ridge on the remote. If you choose to go this route you'll see what I mean. Knowing that this is how the silicone cover and trim ring are held in place re helpful, but I found it very tedious, and I wasn't even sure it would work. But after messing with it for a while I finally got it.So I thought I was good, however since I had reused the old fob, and initially had taken the guts out to try and transfer it to the new fob, I really had to pry the old fob apart, and I think it may have been glued at some point. But the point is that now the old fob didn't seem to snap together very tight. Sure enough I dropped the keys the first time I went to use it (I hardly every drop the keys) and the old fob fell broke back open on impact scattering the parts everywhere. So I knew if I was going to re-use the old fob I'd have to glue it again which I didn't want to do.SO, HERE IS THE DISCOVERY. I really wanted to use the new fob (which actually has a small screw to help secure the fob from being vulnerable to breaking apart) and so I went about trying to really figure out why the old key would not fit the new fob. What I discovered is that the little "hub" on the inside back of the new fob is just a little larger by a very tiny amount than that same hub on the old remote.In the pictures with this review the new fob is on the left and the old fob is on the right. It's very subtle, but in the pictures you may be able to see where I reduced the diameter on the new hub by a very small amount using a xacto knife. You can see on the left side of the new hub how it's slightly narrower than the rest of the hub. It's easy to check your progress and fit with the old key as you whittle the hub down, and it is very evident when you you get it just right and can tell that the old key will now operate smoothly.Put everything back together, and boom, done, it works perfectly! It's a shame to have to learn like that, BUT I will say that the new fob seems to be a great bargain, even if I buy another so that I can have a nice new fob that doesn't show the wear and tear of my learning process!So my personal recommendation is to slightly trim down that hub on the inside back of the new fob and have a nice new remote utilizing your old key rather than trying to replace just the button cover. Replacing just the button cover is feasible but frustrating, and the old fob was pretty beat up anyway. Making the old key work with the new fob, which is really pretty simple once you know the trick, is what we were all hoping for in the first place!

This worked perfectly for a fob that got crushed. I was able to remove the components inside and place them in this replacement. It looks just like the old one and works perfectly. I was even able to lift the cars logo and place it on the new one. Looks like the original.

Worked after a but adjustment. Fob key was off from original keys. Had to shave a few off the original key to be able to fit in the new fob otherwise I would I have to take it in to get specially cut for more than I pay for this Fob replacement. I wouldn't recommend this unless you have no other choice. Best route would to just replace the Fob face cover which you can also buy here on Amazon. You can keep the original Fob remote with just a new replacement for a cheaper price. Changing the Fob face is easy too which you can find alot of videos on youtube that will help you.

Thank you for this. You saved us a couple hundred dollars. But we did have to pay $100 to have someone fit it over our keys. This is not for the average person to fit over the old fob.Or the old mechanism rather

El producto no funciona, no calza con la placa de la llave electronica, parece a simple vista igual que el original pero no lo es, despues de 3 horas intentando que funcionara tuve que volver a mi antigua llave

The video on Amazon is useless. I got more information from a rock. I figured out finally how to get it apart. Then I did what everyone had to do is scrape the round plastic under the key to get it to rotate freely. However, putting the key on is a lesson in never do this again. The spring has to be mounted on key, then positioned and rotated. Good luck with that. The key is mounted on the thickest part of the fob and has to be lifted in order to wind the spring. If you slip then you break off the post the spring goes over. So to fix that I drilled a small hole where the post was and screwed in a small screw to act as a post. Picture shows screw. It worked. Anyway, now you have to put both pieces together but beware, the silver key holder has to go together with the front and back. Good luck. A real pain you know where. I finally super glued the key holder onto one side of the fob. Finally got it together and it sorta works. The top lock button I have to really have to push hard to get it to work. The other 3 buttons work fine. I’m not sure if it’s the circuit board that lays too deep inside the fob. Also, the top button on the circuit board is installed at an angle.So bottom line, expect to spend a lot of time either using a file or scrape with an exact knife the round plastic the key rotates on. Put the key on without the spring and button and rotate it. You can feel the resistance and you will see silver from the key on the outside of ring. That’s where it’s touching.Good luck and have aspirin ready.Update: I had a duh moment. I mentioned the top button didn’t work good. Now I know why. The fob has a white silicon piece inside and I had left it out. Took fob apart, added part and now all buttons work as they should. I just wish the makers of the fob would make the plastic the fob rotates on slightly smaller so one doesn’t have to scrape it to make key rotate correctly. Just make sure as you rotate key to tighten spring that you don’t break the plastic post. If you break it then fob is useless unless you use screw like I did.
