2013 SHO - Erased All Keys...

[Ford Guy 1976]

I purchased a new Launch CRP919E BT scanner over Christmas, I had an immediate need to replace the key fobs as the functionality was getting bad as they were just worn out. I purchased the 2013 Taurus used and it only came with (1) IA key fob, although there were clearly more programmed. At first, I added an Amazon key fob without any issue, the car started and the key fobs worked. I will also note I also successfully added 2 Amazon key fobs to my wife's Lincoln MKX as they were getting a little worn as well, again had no issues. When I tried to add additional fobs to the Taurus the max number of keys was reached for the vehicle. I erased all keys and tried to program 2 new keys, and now the car won't start. The unlock/lock function and remote start works on 1 fob, so I clearly messed up something on the programming side as I now know that 2 programmed IA fobs are required to start the vehicle.

When I try to enter the PATS programming function, the scanner wants the ignition on to access the modules, but the Engine push start/stop button won't function to enable the ignition at all. It will still proceed but then I get access error messages (see attachment) at the end of the 10 minutes period that states "Cannot Get Security Access for BCM".

I recently downloaded ForScan with the hope that might work but not I'm not sure as the ignition won't turn on. Any words of wisdom are greatly appreciated, getting discouraged as I get get this figured and fear it has to go to the dealer. Thanks in advance.

Have you tried physically placing a key in the slot in the center console? One of my fobs lost programming. It won't unlock or crank the car but it will crank it when it's in that slot.

Yes, tried that slot. That is how I initially programmed the fob after erasing all the keys. At that point I thought I had correctly programmed the two required keys......but clearly not.

I know others here have posted to use the Dorman replacements.

As I understand it, that slot will allow the car to start if the fob battery is dead, but I'm pretty sure it will not enable starting the car with an unpaired transponder key.

Where in Iowa are you located? If close enough, I could try my Autel 906BT which has successfully programmed keys previously. If you press an hold the start button will it light the instrument cluster, just not crank, or are you not even able to get into the Run mode at all? From your original post it sounds like one fob still works to lock/unlock and remote start. If that's the case, that fob is apparently still programmed and should enable the push button starting, which would lead me to think there's maybe a blown fuse for or other power issue for the push button if the button does nothing. Two programmed fobs are required to program additional fobs without a high end scan tool, but 2 are not required to start the car or program via a capable scan tool.

Sending you a PM, thanks.

I no longer have my SHO or my MKS. Would someone following this thread mind seeing if their instrument cluster will light up with a press of the start button if the key is not near the vehicle? Maybe there's a power issue since Ford Guy's cluster does nothing, even with the fob that will work to remote start the car.

I just tried this on my wife's MKX with no key the instrument backlight illuminates and "No Key Detected" on the left of the cluster.

On my SHO, I get the same message with no key. I then grabbed the key that locks/unlocks and remote starts the car and get the same "No Key Detected" message. It's almost like this one key is partially programmed. Extremely frustrating.....

Yes, the OBD port has power. I get faults on the RFA and BCM, but didn't initially have these faults when the original keys were programmed. It wasn't until I cleared the keys to add new ones that I started having these issues.

I'll reach out to Jeff tomorrow, thanks for the POC.

After looking through the service manual, you are correct, two Intelligent Access (IA) keys do need to be programmed in order for the car to start. So if only one is programmed, you won't be able to start the car until you program a second key. The service manual does say you should be able to program keys using a scan tool, even after erasing all keys. The IA key needs to be placed in the center console backup IA transceiver. The IA key should be placed in the backup transceiver slot with the buttons facing outwards and the key ring up.

I have several files that I saved from the Service Manual and will send you a private message to see if you want to provide me with your e-mail address to send them to.

Since I know these cars are quite sensitive to battery voltage, one other thing to try, especially since this issue happened after you had the key in the Run position for at least 10 minutes, would be to make sure the battery is fully charged before trying to start or program additional keys. But be aware that you probably can not try to access the PATS system with the hood ajar since that is one of the monitored sensors by the PATS system. You might also try entering through the passenger door since the IA system starts to look for an IA key in the cabin after it senses a door opening. If your interior lights illuminate after opening the driver's door, that's probably not the issue, but worth trying anyway.

Very thorough and appreciated for the greater knowledge. The items I would add you covered. The battery battery battery.shoukd be holding for safety over high 13 to 14v to safely program. I learned that having the hood opened when charging the battery, keeps the system alive so I close mine completely when trickle charging.
