Make sure you clear all DTCs before doing the key clear, If you replaced with used PCM make sure spare key programming is enabled. If all else fails just do a key add with your current keys. The old keys will still be in the PCM but it won't matter as they will not physically turn the switch. -

Hello Sir, we have released beta version V6.12.10 to you, please download it to have a test. And also for this case, you can also try to program Key manually.
After easing key, it will appearing the 10s process bar, please ignition off and program it as following:
1. Turn the ignition key to position 0
2. Cycle key1 in the ignition from OFF to RUN for at least 3 seconds.
3. Cycle key2 in the ignition from OFF to RUN for at least 3 seconds.
4. Cycle key1 in the ignition from OFF to RUN for at least 3 seconds.
Two keys are now programmed. -

yeah right, it needs to be in programming mode first, security needs to be granted. -

You can only program new third key if you have 2 ALREADY programmed keys. you can't program new key this way if you don't have 2 working keys -

I have the same issue with a 2007 Ford Expedition. I replaced the pcm and I have 2 working keys. I can get access to the security functions but when I try to erase keys or any other functions it stops and says "fault detected". The only fault in the old pcm was P1000 which can't be erased with a scanner. Now with the new pcm it says "theft detected, vehicle immobilized". I have the Elite with Ford V6.12. -

Since you replaced the PCM you have a vin mis-match between the PCM & PATS module, not a problem you just have to do the following steps, BTW: in PATS language WORKING keys means keys that will start the vehicle, not turn the ignition switch. If you replaced the PCM you won't have working keys. Also, and I guess you already know this, on this vehicle the PATS module is in the instrument cluster.1. go into the PATS security module (connect a battery charger if needed to keep the voltage at least 12 volts)2. select ICM/PCM parameter reset3. select PCM/TCM parameter reset (if available)4. exit security5. look in the PCM. If you can find Keep alive memory reset do select it. (KAM reset)6. exit diagnostics and wait 1 minute.7. cycle the key to the run position(do not start) Do this 3 times for at least 30 seconds each.8 after the 3rd time go back into the security module and erase all keys.9. exit diagnostics and wait 30 seconds10. cycle key 1 to run for at least 3 seconds then back to off11. cycle key 2 to run for at least 3 seconds then back to off12. again cycle key 1 back to run for 3 seconds then back to off.13 vehicle should now start with both keys.14 add additional keys using the procedure in the manual or let me know if you need to know how.Thanks -

Which scan tool are you using? The process is the same despite the tool, but different depending on the model. The '02 ranger has PATS "E" which is in the PCM. All you need to do for this vehicle is clear all keys, That will put the PCM in learn mode. Then just use the last part of the process(with the scan tool disconnected) to program the 2 keys required to start the vehicle. Don't try PROGRAMMING new keys until after the PCM has LEARN the 2 keys it initially needs. If you're having specific issues just tell us what they are.Thanks
