The fobs appear to be of good quality construction and not some sort of flimsy knockoff one fob programmed, but the second would not program. This seemed to be a bad circuit board. I emailed seller and they sent a replacement circuit board. It programmed immediately on one pass. I requested a replacement circuit board since the key was already cut and only the circuit board could be at fault. I ordered these keys because of the price i was able to program one of them. The other one did not work, but i was shipped a replacement, and now i have two new working keys. You need to program two keys to program. A third key. You cannot use a key cut from a place like aced or true value, because they only clone your key, not program. A key worked great got keys, cut at local ace hardware, store for two dollars: 50.

One key dealer warned me that keys purchased off internet do not work 50 того времени, but they have always worked for me. Maybe eight times now, once i had two working keys, i was able to program third key myself for free. So in my case i need to keep two spares. So if i lose one i can always program another for free and avoid the rip off dealer.
