Review: Works right from the package. - I have finally found a fob that works! Some of the ones I have purchased either will not program or they do not tell you that it needs to be programmed by a dealer. This one was programmed already and all the functions work properly .I have been very pleased with my purchase and would recommend it.
Review: Max keys procedure - Very fast shipping and works as expected. Programming method works easily. If you have a coupe, you need to use trunk keylock. If maximum keys, you need to reset keyfobs by placing keyfobs 5 feet away from vehicle. Turn key 5 times and press in fake key ignition until it displays 10 min countdown, no fob detected. Do this three times until it says ready to program keyfob #1. Make sure you insert fob top down and keys forward. Once last key is programmed press fake key ignition in to exit Programming. Lastly press unlock on keyfobs to secure code and verify they work.

### ⭐⭐⭐⭐⭐ Works right from the package.

### ⭐ Disappointed – Worked at First, Then Failed
*by K***S on August 9, 2025*

At first, the key fob was easy to program and worked perfectly. However, by the second week it stopped starting my car. Now it only unlocks the doors and opens the trunk, and the car says “Key Fob Not Detected.” Very frustrating. I would not recommend this product — just spend the extra money and get a factory one if you can.
