If I am not mistaken, the Ranger line is one of those vehicles that does not have a way to add a "Spare Key" into PATS Memory!MilesL wrote: Sun Oct 08, 2023 8:32 pm I am trying to program a key for a 2000 Ford Ranger with no success. I am using Forscan v2.3.56 with
OBDLink EX. The key is a new OEM Strattec 40 bit key (stamped S)recommended by Strattec for this model truck.
Forscan reports there are 2 keys in memory. I have only 1 physical key which starts the truck and I believe
is also an OEM key stamped S. When I try to program the new key, I insert the old key turn the ignition to on,
the progress bar goes up to about 60+% and requests the ignition be turned off, the old key removed, the new key
inserted and the ignition turned on and click O.K. within 10 seconds (It takes me 4 or 5 seconds). The progress bar
continues for a minute or less and announces that programming has failed. The DTC that is set is B1601. Can anyone
explain what is happening? Is a clone key saved in memory as a second key? I am at a loss to understand this unless
this is a bad transponder chip. I would greatly appreciate any help.
If the PATS menu does not have an "Add Spare Key" listed in the menu(note the "Spare Keys Programable" entry in the attached PATS warning for a 2010 Fusion and see if it is enabled or disabled or even available in your Ranger) or the Ford method of Ignition turned "5 times on/off within 5 seconds ending in Run" does not result in the door locks cycling or the horn chirping, then you cannot add a third key in this vehicle in this way(may not be able to any way as this method(both Scan tool and 5 times) may require inserting and reading both keys already in memory before the third will be allowed and the missing one can't, of course, be read)!
If you are trying to do this with the "Program Key" section it definitely will fail!
You Can only Program Two or more Keys with the "Program Keys" feature after you have used the "Erase All Keys" section to erase all keys and then use the "Program Keys",which will require two key transponders to complete successfully, and while PATS Security is open, program a third and up to 8(assuming the Fleet Mode PID to be available and is enabled other wise 4 is maximum)!
In vehicles without the "Add Spare Key" feature in the PATS menu the only way to add more than two keys is to "Erase All and program at least two to get the vehicle running and then carry on with extras while the PATS security is open!
You say you are getting a B1601 DTC which does mean that a transponder is being read that is not programmed which means the Transponder is, at least, readable and a Stratec with the S stamped(Not etched) is likely Genuine!
At least this hopefully gives you some Ideas?
