Anti theft light flashes fast and won't crank.

I'm hearing things about the neutral control switch but not sure if that's the problem. I messed with the shifter and got it to crank. Any suggestions? 2007 ranger XLT 3.0 V6

Anti-theft light will Flash a Code after 60 seconds, so turn on the key and wait while it flashes rapidly

Code will be 2 digits and start with 1
So
1:1
1:2
1:3
1:4
1:5
1:6

11 Transceiver [transponder coil] not connected, or there is no power to it.
12 Transceiver internal fault.
13 No Key/no PATS key has been used to turn the ignition switch.
14 Incomplete key code received.
15 Invalid key code received.
16 CAN communications error.


The Transceiver is the antenna(ring) around the ignition key slot that reads the key's RFID tag, this is a common failure

One heads up, if you have attempted to start the engine more than 4 times with anti-theft light flashing fast then the anti-theft(PATS) module will shut down for 90 minutes, so even if you "fix it" you won't be able to start engine
You have to let it sit, key off, doors and hood closed for 90 minutes at least, reason for this is that a "thief" won't hang around that long if this was a theft attempt

In 2007 Ranger the PATS module is in the instrument cluster, 2004-2011
You can check Fuses 9, 10 and 33 in cab fuse box
