Review on 🔑 Heart Horse 5-Button Keyless Remote Fob for Cadillac ATS SRX STS CTS DTS M3N5WY7777A 315Mhz – Complete Remote (Battery Not Included) by Kenneth Murphy

The case itself is very thin. The PCB case weighs less than the original case. The buttons seem to wear out quickly. The key looked like a genuine Cadillac key, but this aluminum blank would not work when cut into the original key. Aluminum billets are very thin and bend easily. The locksmith measured the key and said it is NOT the same as the original key. In the end I just used the original key in this case and it worked. All in all, it serves its purpose as a replacement case, but don't expect a key to be usable. And don't expect it to last as long as an OEM case. But then again, I don't think OEM cases are available individually.
