Review: Worked with 2006 MB SLK280 , installation advice - Item: "Beefunny Modified Smart Remote Car Key Shell Case 3 Button+Panic for Mercedes-Benz CLS C E S (1)" for my 2006 MB SLK280. Quality: The fit and finish of this product is very high. This replacement key has a soft membrane for they keys which is an improvement over the OEM key. The OEM key was made of solid plastic shell, and the button material was made of the same plastic, just thinned so it can be pressed. As most people looking for these products have experienced, over time the plastic cracks and fails. One of my OEM buttons had broken completely off, exposing the electronic button below. All of the pieces fit together very snugly, the chrome is shiny, and there are no gaps. The battery compartment has a gasket to keep out moisture, and the mechanism to hold in the batteries is essentially the same as OEM. Like many things German (manufacturing in China), this key really is quite an intricate piece of engineering, with sliders, retention springs, and locking mechanisms. There is no metallic logo. It looks like you can perhaps pop off the smooth circle on the back and replace with a black plastic piece, but I did not try this. Manufacturer: The unit itself is from KeyEcu model B07QZPJGBV. It comes with two lenses and after communicating with KeyEcu through their WhatsApp number, I was able to piece together that there is no IR communication reason to use one lens over the other, and to simply use the one that fit best. For my key that was the lens with two bumps. Even though there was a language barrier, KeyEcu were quite willing to communicate and we exchanged around 40 texts. They tried multiple times to send me the video file above, and even though it didn't answer my question, they still communicated after that and eventually we understood each other. Installation notes: The white retaining clip in my OEM key broke when pulling the circuit board out. This kit has a new replacement part anyways, but it is shaped differently and will not work to retain the circuit board in the OEM plastic housing. I have seen another YouTube video where the white plastic clip also broke, so anyone attempting to remove the circuit board should assume the same and consider that you will not be going back to the OEM key once you start this process. The metal pieces truly do slide up before popping out. This was a little difficult on mine, as the fit was so tight I didn't have much room to wedge a knife blade. Once apart install the circuit board in the side with the buttons. I used the black retention plastic to provide more support in the fob. My original metal key clicks into the new fob, and seems to be well held, but does not have the same loud "click" as the OEM version. In all very impressed with build quality, and willingness to of manufacturer to communicate.
Review: Cheap quality - Not good quality at all buttons feels cheap and looks cheap

## Questions & Answers

**Q: Where is the red light?**
A: It’s there same spot as the original black key. Everything on the new key works properly. My only complaint is there is no mercedes star badge there is some plastic button that pops out and a plastic star you can put in there but it’s not the chrome mercedes star.

**Q: seller is showing a pic of older style key fob and insinuating this is a conversion. Is it a simple pull the circuit board and key / replace?**
A: Yes, I took out my old chip and manual key and transferred them to the FOB.

**Q: Does it come with the emblem on the back?**
A: The one i got has emblem in separate small bag so you can stick it on the shell.

**Q: If I have an original key fob, may I put the original logo from one to another?**
A: No you can't.  I thought that too before purchasing. It has a circle that you take th a cover off  and leaves a hole in  which you put a horrible plastic black logo included...

### ⭐⭐⭐⭐⭐ Replace That Chewed-Up Key Fob!
*by T***R on December 27, 2020*

I have a few old 'Benzes. One of them is a low mile 2001 AMG. Stunning car. I reach into my pocket to get the key and fire her up & go for a long, long drive down the coast. Out come my keys... my other cars and this one, too. The plain, anonymous-looking, and (20 years on) scratched, punctured, faded key. Could be for a KIA, for crying out loud! Really, Mercedes? Much time was spent by me attempting to find an "upgraded" fob, with the chrome sides to it. I've always thought that was a great look, and I'm glad to say this case does not disappoint. It looks similar to the design that I saw first on the W211 E-Class. And... it feels great in your hand. The plastic is sturdy, and the chrome (okay, "plastichrome". Ugh.) feels cool against your hand. The fit is tight, and the case has no flex. (I washed the original a number of times and it never failed ((!!!)), and this case appears to be equally tight, but I don't think I'll bet the $3-400 board inside the thing.) Do note that although appearing very well manufactured, there is no 3-pointed star on the back. (I found a few all-black cases that did... but what I really wanted was the chrome encasement. I already know it's a 'Benz.) The process is so easy it is almost silly. Eject the Valet/Hard Key from its lair. Slide the lil' grey button near the key ring and pull. Using the Valet/Hard Key, push the small grey box that you see inside the back side of the key while simultaneously using your fingernails to pry the back of the battery drawer away from the body of the fob. This is essentially the process for replacing the batteries, so far. In fact, it is identical, except that you will take a pair of needle-nose pliers and grip onto the board-like thing inside. This is the guts of your key, the thing that Mercedes wants to charge you hundreds of dollars for. Using your pliers, give the board a firm tug. My board popped free without an issue, and I just slid it into the new fob after replacing a small plastic beam (included with the kit) on the trailing side of the board, some sort of a spacer. The board slid into the new case with a reassuring "click". From there, swap the batteries into the new fob's battery drawer (polarities!), reinsert the drawer, snap it in securely, and do the same with your old Valet/Hard Key. You're now finished. The first time takes longer, what with figuring what goes where and what to do with it once it is there (isn't that the way!), but now I could do it in 5 min. Now, take that great looking new key in hand and go for a spin!
