Dealer or specialty locksmith shop. A new transponder key will need to be purchased, cut to work with existing lock cylinder, and then the ECM and PATS will have to be reprogrammed to accept new transponder key.
@KenF any idea on the cost?
You should get 2 keys at a min. With 2, you can have a key cut and program more yourself. Call around for prices, the keys are cheap and cutting them. Are you purchasing a key fob for both as well? Then add programming costs. Dealer will probably be more.
Try the info in this post: https://www.fordf150.net/howto/patskey.php . You'll have to have at minimum a locksmith cut a new key from a blank, the chipped blanks cost about $20 and higher, but let the dealer of locksmith place obtain it as it's easy to buy the wrong one. So you are looking at buying the following: Two new blank transponder (chipped) keys. Key cutting to match existing lock cylinder. Reprogramming to have existing PATS accept new keys. The dealer MIGHT be able to cut the keys by code, the dealer that sold the vehicle may keep those codes for several years (15 years?). You'd have to check with them on that, otherwise a locksmith can do it be impressioning.
@KenF Thanks! I hoping the misplaced key turns up before monday morning.
We found the key! Woo Hoo!! Now I'm going to get copies made. Thanks for the help!
