Re: key problems
The locks and keys on Fords were good for many years. I have an 1985 F150 with 200,000 miles and they are still fine. (the old 5 cut keys). Then they went to a 10 cut key and for a while now an 8 cut key. 8 cut is the worst, prone to premature wear, especially when people have 5 lbs. of stuff hanging from them.(not saying you do). When you had new keys cut, were they just copies?, or newly cut keys back to factory specs.?
(BTW Fordtech., good advice, as usual!)
