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 Marc Zitnik

This saved a lot of money and ensured I didn't have to pay a fortune to the dealer if the original key was lost. One tip though is to take it to a locksmith. I bought two packs and took them to the hardware store. Luckily I only had one cut and left the other one on the counter and went to check. It was cut wrong even though he put it in a machine that was supposed to cut and program it. I found a simple tutorial on YouTube to program it. The warning is there too. It took a second try, so don't give up. Also, some videos say that the key must be left for 10-30 minutes. Our 2008 Ford F-150 did NOT require this - it was easy.
