I have a 2008 ford f550 super duty with the anti theft light blinking it blinks fast for about 2 mins then slows and blinks once then six time at about once a sec. Any help plz
If you use a bump button to start the truck with the key in the on position you can use a code reader and delete the codes then it should start if this is the problem it has probably got to do with your dpf
Is there any way that i can bypass the theft???
You somehow activated the antithft system. Did someone reach in and open a door from the inside with it locked? Can you recall how it activated? It should be flashing fast now.
There are alarm deactivation switches on the driver door lock and other outside door locks. You should have been able to unluck any door with a key fob or a key, and deactivated the alarm. Maybe you have a door deactivaion switch that is bad.
Start there.
PS, this hsould be covered by warranty if within warranty and a defective switch
The battery musrt be fully charged.
Here is some info:
SECTION 419-01: Anti-Theft - Passive Anti-Theft System (PATS)
2008 F-Super Duty 250-550 Workshop Manual
DESCRIPTION AND OPERATION
Procedure revision date: 01/02/2007
Anti-Theft 
Printable View (83 KB)
NOTE: If a new instrument cluster (IC) or the PCM (or both) is installed, the parameters MUST be reset in both modules or the vehicle will experience a passive anti-theft system (PATS) no-start. This will occur even if the vehicle is not equipped with PATS. Refer to Passive Anti-Theft System (PATS) Parameter Reset in this section.
The PATS is available on this vehicle as an option. The vehicle must be ordered with or without PATS as per the customer. It is not a dealer-installed option.
PATS consists of the following components:Anti-theft indicator (located in the IC)
Encoded (the key contains a transponder) ignition key
PATS transceiver
IC
PCM
PATS uses radio frequency identification technology to deter a drive-away theft. Passive means that it does not require any activity by the user.
The vehicle is equipped with 2 PATS keys. A maximum of 8 PATS keys can be programmed to start the vehicle. If additional PATS keys (more than 2) are desired, refer to Key Programming Using Two Programmed Keys. If additional PATS keys (more than 8) are desired, refer to Spare Key Programming - Unlimited Key Mode in this section.
PATS Function
NOTE: If the IC or the PCM (or both) is being replaced, the parameters must be reset in both modules or the vehicle will experience a PATS no-start. This will occur even if the vehicle is not equipped with PATS. PATS vehicles and non-PATS vehicles have parameters in the IC and the PCM and they must be reset whenever either (or both) module(s) is (are) replaced. Refer to Passive Anti-Theft System (PATS) Parameter Reset in this section.
The PATS function is controlled by the IC. The PATS uses the IC to carry out all of the PATS functions such as receiving the identification code from the PATS key, issuing a signal to the PCM to control the starter and fuel injectors enable, and initiates the key interrogation sequence when the ignition key is turned to the ON or START position. Because of the interaction between the IC and the PCM, there are parameters that must be reset if the IC or the PCM (or both) is replaced. Refer to Passive Anti-Theft System (PATS) Parameter Reset in this section. If the IC must be replaced for any reason (PATS concerns or IC concerns), the PATS keys also must be programmed into the new IC. Refer to Key Programming Using Diagnostic Equipment in this section. All elements of PATS must be functional before the vehicle will start. If any of the components are not working correctly, the vehicle will not start.
PATS is active only for a few seconds when the vehicle is starting. It is not a PATS concern if the vehicle stalls after it has been running for a minimum of 3 seconds. PATS will not disable a running vehicle.
PATS may cause a vehicle no start due to either the fuel injectors not operating or the starter not operating (starter relay does not close) or both. Always check for PATS DTCs from the IC and the PCM when a no-crank or no-start condition exists. A low state of charge (SOC) in the vehicle battery may cause the PATS to allow starter operation, but prevent the fuel injectors from operating. If the theft light does not prove out (it may be either flashing or glowing steadily) and one (or both) of the previous conditions (fuel injectors and/or starter inoperative) are present, it may be due to a PATS issue. If the theft light proves out, it may not be a PATS issue. If the theft light does not illuminate at all, it may be an IC issue. Refer to the Symptom Chart in this section.
PATS is not compatible with aftermarket remote start systems, which allow the vehicle to be started from the exterior of the vehicle. These systems may reduce the security of the vehicle, and also may be the cause of no-start concerns. Remote start systems must be removed from the vehicle before any PATS-related no-start concerns are investigated.
Unlimited Key Mode
PATS contains a feature called unlimited key mode. This feature allows a customer to program more than 8 vehicle keys, if requested. Each vehicle in unlimited key mode is set up with a special unlimited transponder security key code. This allows all the customer vehicles to share the same mechanically cut keys. For an individual customer, any randomly selected security key is acceptable. Refer to Spare Key Programming - Unlimited Key Mode in this section.

Pinpoint Tests
Pinpoint Test A: DTC B2103 - Antenna Not Connected
Normal Operation
The passive anti-theft system (PATS) transceiver communicates with the PATS key. During each vehicle start sequence, the PATS transceiver reads the PATS key identification code and sends the data to the instrument cluster (IC). The control functions are contained in the IC. The IC carries out all of the PATS functions such as receiving the identification code from the PATS key and commands the PCM to enable the engine. The IC initiates the key interrogation sequence when the key is turned to the ON or START position.DTC B2103 (Antenna Not Connected) - sets when there has been a PATS transceiver antenna failure. The PATS transceiver may need to be replaced.
------------------------------------------------------
Pinpoint Test B: DTC B1600 - PATS Ignition Key Transponder Signal Is Not Received

NOTE: Large metallic objects, electronic devices on the key ring that can be used to purchase gasoline or similar items, or a second key on the same key ring as the PATS ignition key may cause vehicle starting issues and record DTCs under certain conditions. If a fault cannot be identified, examine the customer's key ring for such objects or devices. If present, inform the customer that they need to keep these objects from touching the PATS ignition key while starting the engine. These objects and devices cannot damage the PATS ignition key, but can cause a momentary concern if they are too close to the key during engine start. If a concern occurs, turn the ignition OFF and restart the engine with all other objects on the key ring held away from the ignition key. Check to make sure the PATS ignition key used by the customer is a Ford approved PATS key. (PATS keys from Ford, Rotunda, Strattec, HUF are approved Ford PATS keys)
---------------------------------------------------------------
Pinpoint Test C: DTC B1601 - PATS Received Incorrect Key-Code From Ignition Key Transponder
Normal Operation
The PATS transceiver communicates with the PATS key. During each vehicle start sequence, the PATS transceiver reads the PATS key identification code and sends the data to the instrument cluster (IC). The IC will then send a message to the PCM. The PCM will carry out the function of controlling engine enable. The IC initiates the key interrogation sequence when the key is turned to the ON or START position.DTC B1601 (PATS Received Incorrect Key-Code From Ignition Key Transponder) - sets when there is an unprogrammed PATS key. The concern may not be with the PATS key itself, but possibly the key may need to be programmed into the PATS memory (unless the maximum number of keys are already programmed).
This pinpoint test is intended to diagnose the following:

PINPOINT TEST C: DTC B1601 - PATS RECEIVED INCORRECT KEY-CODE FROM IGNITION KEY TRANSPONDER
NOTE: Large metallic objects, electronic devices on the key ring that can be used to purchase gasoline or similar items, or a second key on the same key ring as the PATS key may cause vehicle starting concerns and record DTCs under certain conditions. If a fault cannot be identified, examine the customer key ring for such objects or devices. If present, inform the customer that they need to keep these objects from touching the PATS key while starting the engine. These objects and devices cannot damage the PATS key, but can cause a momentary concern if they are too close to the key during engine start. If a concern occurs, turn the ignition switch off and restart the engine with all other objects on the key ring held away from the ignition key. Check to make sure the PATS key used by the customer is an approved Ford PATS key (PATS keys from Ford, Rotunda, Strattec, HUF are approved Ford PATS keys).
NOTE: Only 8 PATS keys can be programmed into the IC during normal programming procedures (unless the unlimited key mode is enabled). If the N_KEYCODE PID reads more than 2 and less than 8, the concern may be the PATS key being used is an unprogrammed key. Verify this by also viewing the MASTERKEY PID. It must read PRESNT for the key to be valid.
Pinpoint Test D: DTC B1602 - PATS Received Invalid Format Of Key-Code From Ignition Key Transponder
Normal Operation
The PATS transceiver communicates with the PATS key. During each vehicle start sequence, the PATS transceiver reads the PATS key identification code and sends the data to the instrument cluster (IC). The IC will then send a message to the PCM to control the engine enable. The IC initiates the key interrogation sequence when the key is turned to the ON or START position.DTC B1602 (PATS Received Invalid Format Of Key-Code From Ignition Key Transponder) - sets when only a partial PATS key was read.

2008 F-Super Duty 250-550 Workshop Manual
GENERAL PROCEDURES
Procedure revision date: 01/02/2007
Key Programming Using Two Programmed Keys Printable View (81 KB)
NOTE: This procedure works only if 2 or more programmed ignition keys are available. If 2 programmed keys are not available, refer to Key Programming Using Diagnostic Equipment in this section.
NOTE: The PID SPAREKEY must be enabled for this procedure to operate. If this PID is not enabled, refer to Key Programming Switch State Control in this section, then select SPAREKEY programming switch; ENABLED. The PID SPAREKEY is set to ENABLE when the vehicle is built.
NOTE: If the programming procedure is successful, the new key(s) will start the vehicle and the anti-theft indicator will prove-out for approximately 3 seconds. If the programming procedure is not successful and the new key(s) does not start the engine, leave the key in the ON position for at least 3 seconds, then turn the key off. Repeat the key programming procedure from Step 1. If the failure repeats, refer to Anti-Theft in the Diagnosis and Testing portion of this section to review the DTCs and carry out the appropriate pinpoint tests.
NOTE: A maximum of 8 passive anti-theft system (PATS) keys can be programmed into the instrument cluster (IC) during this programming procedure, but only if the PID SPAREKEY is ENABLED.
NOTE: A minimum of 2 PATS keys must be programmed into the IC before the vehicle will start.
NOTE: If the vehicle is in unlimited key mode, this spare key programming procedure still functions. Any 2 keys that can start the vehicle can be used to program an additional unlimited key.
NOTE: If additional keys are to be programmed, and the remaining keys are with the customer, or are not available, instruct the customer to refer to the Owner's Literature for instructions on programming the remaining keys. In this case, the PID SPAREKEY must be enabled.
NOTE: If the steps are not carried out as outlined, the programming procedure will end.
NOTE: Ignition keys must have a correct mechanical key cut for the vehicle and must be PATS encoded keys (contain a transponder).
NOTE: This procedure is not necessary if only the PATS transceiver was replaced. Replacement of the transceiver does not erase the PATS key codes in the IC.Insert the first programmed key into the ignition lock cylinder and turn the key from the OFF position to the ON position (maintain the key in the ON position for a minimum of 3 seconds and less than 10 seconds).
Turn the key to the OFF position and remove the first key from the ignition lock cylinder.
Within 5 seconds of turning the key to the OFF position, insert the second programmed key into the ignition lock cylinder and turn the key from the OFF position to the ON position (maintain the key in the ON position for a minimum of 3 seconds and less than 10 seconds).
Turn the key to the OFF position and remove the key from the ignition lock cylinder.
Within 10 seconds of turning the key to the OFF position, insert the unprogrammed key (the new key) into the ignition lock cylinder and turn the key from the OFF position to the ON position (maintain the key in the ON position for a minimum of 3 seconds and less than 10 seconds).
If it is desired to program additional key(s) (only up to 8 keys total can be programmed into the IC), repeat Steps 1 - 5 for each additional key that needs to be programmed.
Start the vehicle with the new key(s).

Check fuse number 36 .Its 5 amp fuse.Its located in passenger compartment fuse box.Remove this fuse completely out and inspect, if this fuse is blown, replace it.If its not blown, then let the fuse remain out for 5 minutes, then reinsert the fuse back in its slot.Then check.--------- Thanks.Helpmech.
If fuse 36 is checked ok and removing it and reinserting it is not resetting the anti-theft system, Then problem is with ignition key.Or problem with ignition cylinder or the computer.--------
The theft sensor is in the ignition lock cylinder, There is a chip in ignition key, which this lock cylinder sensor detects.If the key chip is faulty or key lock cylinder sensor itself is faulty, then also anti-theft light will not come ON.But if this both are checked ok, then yes its computer related problem.Many a times getting the computer reprogrammed by dealer helps.But in some cases, either theft module or computer needs to be replaced.------------
Thanks.Helpmech.
Then the ignition key and ignition lock cylinder theft sensor.----------
Both needs to be checked.-------- Any of the one is not functioning right, causing no theft light. Also check the voltage at fuse number 36 slot. Where the fuse number 36 is inserted, check there, do you get 12 volts with ignition ON.------------ This will help.Thanks.Helpmech.
There must be the key transponder, where the key cylinder goes is there a black ring around the steering coloum with a connector mounted under it.Either that is the problem, or the problem is with theft controlling IC.-----

Ok, try this procedure.Disconnect car battery terminal, then insert the key in ignition, then turn key to ON position.Then reconnect the car battery and see if car starts and runs, by this procedure.-------
Also Replace the key fob battery and see if the car starts after key fob battery is replaced.------
Keep updated.Thanks.Helpmech.
The anti-theft code is 1:6 which is Faulty link between PATS module and EECV Go to main dealer.
---------
1:6 Faulty link between PATS module and EECV Go to main dealer If the LED illuminates for 4 seconds but the engine does not crank, PATS is working correctly and there is a fault elsewhere. Try starter solenoid or battery. If okay go to main dealer. If the LED illuminates for 4 seconds and the engine cranks but does not start, PATS is working correctly and the fault lies elsewhere. Check the Fuel Cut-Off switch. If okay go to main dealer. If none of the above checks resolves the problem then the system will need to be connected to WDS at a main dealer for a diagnostic check. If the engine starts normally but the LED stays on, wait for one minute. The LED may then flash a code 2:1. This is showing a 'fault' that there are less than 3 keys programmed into PATS. One of more keys need to be programmed to stop this code. Any other code needs referring to the Ford main dealer.-------------
OBD II tool will not work.This can be scanned by scan tool at dealer.Its not possible to troubleshoot without an NGS tester or WDS scan tool.That will only tell what is faulty, and as per that troubleshooting will be done.---------

this will help.Thanks.Helpmech.

removed fuse 36 5 amp left out for 5 minutes no change
fuse ok power on fuse removed and inspected and left out for 5 minutes no change. no communication with ids security light on flashing fast truck will not do anything (spin over or fuel pump)
cannot reflash or check, no communication with ids when computer is plugged in
computer is not the issue replaced still no data out of data link and theft still flashing have donor truck removed parts off of it. any other suggestions
this truck does not have a theft ring around the cylinder where you put the key in any suggestion as to where it is
there are no wires going to the lock cylinder only manual cable coming out of switch
does not have ring around key on 450 has a blak box mounted to the top of the switch with three wires going to it. Is nothing like to picture you sent me
followed steps as you directed, truck will not turn over or start and theft light is still flashing rapidly on dash. did find on all data that the anti theft is flashing a code 1:6 which is no communication. computer will still not communicate with pcm through obdII
ford kept it for several days, they cannot establish a data link that is why i am working on it there can be no data link established between laptop and pcm (ids and pcm) I have the ford software and laptop, but cannot establish a signal to troubleshoot
