Keyecu Smart Key Fob Replacement 4 Button for Chevrolet Corvette 2008-2013,FCC ID M3N5WY7777A ,P/N:25926479 25926480

Both fobs worked and programmed right into the customers car. Only issue was one got stuck in the programmer slot. Not sure if it was my error or the key. I eventually got it out. I was pleasantly surprised they both worked so well. Every other reproduction key out there is $50+ and they likely come from the same foreign factory. Though it’s likely the pricer keys from other places have been tested and these haven’t. Buy an extra just incase one doesn’t work. You will still spend less money in these than anywhere else (including buying the extra)

Worked great on c6 z06

As a few people have mentioned, it's hit or miss as to whether these program out of the box. I ordered 2, only 1 worked so i exchanged the other one and the next one work, so I guess technically, for me, it was a 66.7% "accuracy" rate. I took the key blanks to the chevy dealership to have them cut for my car and they used both my existing factory key AND the code from GM for my VIN and neither one worked. The blanks were too wide. Then, a few months later, out of nowhere, both fobs stopped working to start( or lock/unlock) the car. I put in fresh batteries and even wiped the car's programmed fobs and went through the whole process again and they wouldn't program. While I wanted these to work SO bad because the dealership will charge you 4 arms, 6 legs, and your first born for a new fob with key from GM, these just don't cut it. Buy once, cry once and just buy a factory fob/key

Product arrived fine but would not pair with my car or even talk to the car. Took back cover off thinking no battery but it was there so I replaced it but still no signal. Upon inspection of the battery compartment found the positive battery side battery holder clamp that touches the circuit board was crushed flat and not contacting the board. Using some small tweezers I raised the 2 prongs gently until they were high enough to touch board. Fob communicate without any more problems and was programmed to car successfully.

The key I received worked great! It was compatible with my 2009 C6 corvette. Easy to program I used instructions from YouTube and it worked first time! (I’ll provide a picture of the instructions) worth the price! Dealership and locksmiths was going to charge me 150-400 for the same thing I did with a 30$ key from Amazon in 30mins.

I am giving 3 stars because this fob arrived inoperable, but I was able to get it working. I changed out the battery in it and went to go program it. It was programmed, but I could only get it to lock and unlock the doors, wouldn't start the car (No fob found message displayed when trying to start). I plugged in my fancy scanner and pulled up a function which displays the status of all programmed keys. I noticed that the fob would become active only when pressing the buttons on it so long story short, I had to bend the electronic contacts in order for the fob to be active all of the time. It now starts the car. Great price for a working key fob and not too much work.

Bought this as a replacement. (Actually bought 2) I immediately had to send 1 back after taking over an hour reconfiguring and learning the new remote. It had worked sporadically and most of the time didn’t work at all. Got the new one and this was the same but not as bad. I would say that 40% of the time it will not open doors or start vehicle without actually pressing one of the buttons to make the car identify it. About 5-10% of the time even after using it to enter the vehicle, the car will not start with the error code saying “No Fob Detected” this usually requires reliving and replacing battery, shaking fob, pressing multiple buttons and a couple of times I had to put the fob into the slot in the glove box just to start the car. It is the same with both fobs I ordered and the one I returned. It is a subpar product that honestly stresses me out everytime I leave the house worried about if it will start my car when I need it. I also noticed the battery (Brand new Energizer) died and had to be replaced less than 4 weeks after learning my vehicle. Would not recommend to family or friends. I have it a generous 2 stars because the appearance matches the OEM FOB and because it does work properly about 20-30% of the time.

So I bought this key about 4 weeks ago and it worked perfectly far as programming it. Had my wife purchase 2 more for me for. The next 2 I received after several attempts, hrs of trying. Would not program to my car. I have a c6 corvette and Ik what I’m doing far as the process. So it’s a 50/50 chance u get a good fob I guess. 3 stars still because the first one i ordered saved me dealership fee. Will have to return the other 2 Update: Turns out I switched the batteries from the ones they came in and they worked…so make sure u buy new batteries because the batteries they come with are not from the u.s.

Me pareció buena la calidad, lastima que viene sin el logo de la marca en la parte de atrás pero entiendo que es para Cadillac y Corvette. RECOMENDABLE.
