Review: Excelente producto Me encanto la llave funciona de maravilla La recomiendo ampliamente Mi coche es un cadíllac CTS 2008 Un punto a destacar es que te dicen como programarla y asi evitas altos costos
Review: When in hand I can open the doors and trunk. I can also lock and unlock the doors. Unfortunately using the key fob I cannot remotely open the trunk nor start the car with the key fob. Sadly the blank key in the key fob is the wrong size and cannot be cut to be able to open the driver side door. I hope Keyecu will be able to remedy these shortcomings. Will let you know. Update: Keyecu sent me a replacement keyfob. Blank key is the right size and all remotes are working. Now five stars ... many thanks.

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.
