Please help!  Truck was stolen last week  Got it back but thieves have one of my keys.  I dug out my DS708 an followed video instructions.  I went into PCM, special function, PATS etc.  I waited the 10 minutes for security access.  all went normal.  I went to delete ignition key which it said to do to delete all keys.  It did delete the keys BUT it was SUPPOSED to popup a new screen with instructions to proceed programming the new keys.  It did not.  The screen blipped and it went back to the main PATS scree.  So I went back in and waited 10 minutes again for it to get security access.  Only this time I tried to program new key and it says it can not communicate with module..  If I try to re delete etc it says unsuccessful fault detected.  I am assuming because there are now no keys programed to the PATS module?  So truck is stuck and can not program new keys.  What do I do?  Is this a software bug??  Or what do I do?  Any help is greatly appreciated.  I am too far to have this towed to a dealer.  And first its stolen now its useless...

 Thank you,  I should have mentioned that I tried that as well.  After googling I have tried it without the ds708 connected to the vehicle and it did not work.  I also read elsewhere that I needed to start by having the ds708 get security access and THEN disconnecting it and trying to program keys and it still did not work.  I also read doing a parameter reset would make it start over basically and to then try programming the new keys and it still did not work.  one key I am trying to program is new straight from the dealer today and the other is one of my old keys for this truck that was working prior to being deleted.

 ok thanks,  I had to get a ride so I will try again monday.  Its funny tho because everything i found say more than three seconds but no more than 10.  but i'll give it a shot.  finger crossed.  :)

 OK, so I'm back at my truck and I'm trying it again and it's not working.   I did as you said and did it for 10 seconds and it didn't work.  I did another Google search and found another place that supposed to be from all data that says six seconds so I tried that and it didn't work. I also tried doing a parameter reset for each time and trying them both again and it didn't work.  Every time I try and I go through the key process of Keyon key off in the next Keyon in the next key off and the original key back on and back off and then wait a few seconds and try to start the truck it just clicks and says starting system failure on the dash. Also I'm not seen any num keyvalue anywhere in the autel. Only the key status in the PCM live data.  Only tells me at the ignition is currently on or off.

 As an update I kept trying and it still didn't work. I also noticed that every time I make in a tent it keep storing to new codes into the PCN memory.
