Transponder key; PCM programming update

[tmarat]

I have a 2008 Ford Explorer 4.0L 5R55S

From reading the forums it seems I need to have two keys to be able to program another spare. If only one key, then need to go to a dealer who using his equipment clears the old key code from PATS and programs two new keys in. But we do not have any official dealers (used to be, but stopped selling fords). Is it possible to do this on your own? What equipment or software do you need?

Also, in my vehicle, does it have any control module specific to the transmission? Or is everything controlled by PCM? My transmission most of the time engages R with a bump. Shifts are also quite bumpy. Especially when accelerating (not hard) and you let go of the pedal just before the next shift, then it engages with a jolt on your back. Though sometimes everything is smooth. I have read programming update can sometimes alleviate this. Again, what kind of equipment necessary?

On the key question, it will need to be programmed with a special box. I had one key also and checked around with locksmiths and found a local one that could program it.
They were cheaper than the dealer also.

Pretty sure the transmission update is a dealer service only. You might call around anyway.

Can SCT Xcal be used for the updates?

If you have the Ford update the PCM or tranny bump issue. You will have to contact SCT for a new program. I had mine done and my SCT was incompatible. I contacted SCT, told them what happened, and they sent me the new tunes free of charge.
