So, on my 2008, I only have one key. Can I or can I not, program a 2nd key?

 

No, you cannot do so without an appropriate scan tool (or equal).

 

Concurred

 

Been quoted anything from $75 to 200 to cut/program a transponder key. A couple of places absolutely won't touch cutting my own key blank. Says it breaks their bits.....

 

Have you tried Walmart?

 

I do not believe that the WalMarts around here program transponder keys. They can barey cut a house key.

Found a place that did it for about $40. I already had a key that I purchased online. One problem I ran into was most places want you to buy their key. I was told twice that "we do not or do not like to cut "aftermarket" keys". But they will sell you a basic plain transponder key for $49 or more. I can buy them online for less than $15. I bought the one with the remote door locks built in for about $12! So this place went on about how they couldn't guarantee it would work, etc. It worked fine. I programmed the door locks in a few seconds and was done.

 

The Walmart here has the computerized cutting machines that will cut and clone a transponder key. They aren't that expensive, I think it's about 50 bucks including the blank.

 

2010 F 150 replaced PCM and truck wont start. Anti Theft still flashing, someone told me I have to reprogram my keys to the new PCM. Anyone have any advice on how to do this or is it even possible

 

It is MANDATORY that the PATS system be reprogrammed when a PCM is replaced on any F150 starting in 1999.

Please read the WHOLE thread.

 

Is this a dealer only fix

 

Dealer or a shop that has the right equipment.
