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)

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.

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

This replacement key fob works great. Note: it may take several tries to get to the programming mode with the 5 trunk key turns required to get it into the programming mode. I tried a couple of times and then went back to the on-line videos. One of the videos made a point of this, and once I tried again using several series of 5 key turns it worked on the fourth try. Cutting the keys was a failure at my local hardware store. Neither of the cut keys would even fit into the lock more than half way. I reversed the way the key is mounted and it still didn't work. The hardware store has been very competent in the past, but it may well have been their problem.

Only one of the two programed. Changed battery and still would not. If only the second one would have been as easy as the first. Hopefully the company will make this right. If they do I will update my review, for now I would not recommend.
