Review on Pair of KeylessOption Chipped Key Transponder Replacements for Ford 4C H72 Ignition by Len Chandler

These keys work great (and still work). They were programmed with the Ford Automotive Programming Engine (see owner's manual) and also viewed on youtube.com. I had them cut by a locksmith for $4 each. They only get a 4 out of 5 rating because even though they were programmed by the car itself as key 3 and 4, I couldn't get the forescan app to successfully read that key as key #1 or #2 in "Reprogram All" to program. Key maneuvers required when reprogramming the PCM when PATS is involved. Forescan was great with original Ford keys but didn't like these keys. However, the car itself was able to program these keys perfectly, which 95% of users do, so they still get 4 out of 5 stars because they work and cost a fraction of the price of a genuine Ford key. And I didn't have to get the dealer to program them for a ridiculous price. Two keys cut and programmed for $30, dealer was $500.
