Review on SCITOO Uncut Ignition Chipped Key Fob for Ford (1pcs) - Compatible with F-150, Escape, Expedition, Explorer, Focus, Fusion, Mustang, Ranger, and Taurus 2001-2010 - H84PT40 691259 by Isaiah Bower

Bought this key for about 1/15th the price the factory charged for it. Trimmed with local equipment. Followed the instructions I found online. The key started the engine but would not turn and the security light flashed when trying to program. My buddy has a $600 diagnostic computer. We put it in key programming mode. It took ten minutes. I repeated the steps I found online after we noticed that the security light for that key had stopped flashing. You will need two master keys to complete the process. With this key and fob I got a third set for about $20 versus the $230 the dealer wanted for both with no cutout/programming. Take it. Find the guy with the diagnostic processor. Works like original.
