Review on KeylessOption Keyless Entry Remote Control Car Key Fob Replacement (CWTWB1U511) - Ultimate Convenience for Your Vehicle by Mike Rogers

Do not buy this product. I have successfully programmed it for my Ford Expedition and although it unlocks and locks the doors it does not disable the factory anti-theft system like the original factory keyless remote so the car will not start. The support team said it was a problem with the machine, but it wasn't. I called the Ford dealer who said that after the sale the remote controls could not disable the anti-theft device. They referred me to the instruction manual which confirmed it. Without this feature, the product is unusable and this defect was not mentioned in the product description. The seller did not accept the return because I bought it as a backup and I only discovered the problem after the warranty expired.
