My security system in my 2010 e150 Ford van has put the engine in a no start mode. What can I do to get it started?

It is still the same because you can't remove a factory security system. There is too much involved.

try disconnecting the battery for a couple of minutes so the electrical system reboots itself with a clean start. That might fix it. IU would give it 10 to 15 minutes disconnected before reconnecting and trying it. Further to that i would say take it to the dealer and send the bill to the place that did your oil change

You have to bleed the system. Not very likely an air lock, since air will come out of the fill bottle sooner or later. You can try removing the rad cap (when its cold) start it up. put heater on high, let it run and check for good coolant flow in the rad. Any trapped air will also come out.

The car will not be able to start with your own key. This reset is for ford cars. Press loud speaker icon on the remote entry key. The alarm will sound. Now put your key in the ignition and to it to the on position. This will reset the alarm. Now turn key to off position. Then turn key back to the on position. The securilock indicator on the instrument panel will light up for 3 seconds and then turn off. The securilock feature is now deactivated. Turn key to off. Then try to start the car with the key. This procedure should work for most ford cars.

the system is either hooked to the battery or it has a fuse try disconnecting them

the immobilizer might be stuck on, remove battery then go turn the ignition to number 2 for a few seconds then connect the battery make sure you put red lead on first then the black lead, then get in the care. it should have fob remote on this model so remove the fob off the keys. turn key to number to then press the fob buttons lock and open that should turn off the immobilizer, the doors should lock and unlock , then turn key back to 0. wait a second and then try to start engine. ,

TAKE TO DEALERSHIP LET THEM CODE SCAN VECHICLE . YOU NEED DIAGNOSTIC EQUIPMENT TO TROUBLE SHOOT THE PATS SECURILOCK SYSTEM. SOUND LIKE PROBLEM COULD BE KEY CODE.KEY COULD BE WORN DAMAGED.FAULT IN ECM OR IMMOBILIZER CONTROL MODULE. BEWARE WHEN THEFT SECURITY MODE TURN ON SOON OR LATER CAR WILL NOT CRANK OR ENGINE CUT OFF WHILE DRIVING.THEFT SECURITY SYSTEM WILL SHUT DOWN FUEL PUMP.

it resets itself.

Principles of Operation
The PATS uses a specially encoded ignition key. Each encoded ignition key contains a permanently installed electronic device called a transponder. Each transponder contains a unique electronic identification code out of over 18 billion, billion combinations.
The passive anti-theft system (PATS), also known as SecuriLock ®, uses radio frequency identification technology to deter a drive-away theft. This system is known as SecuriLock® in North America, Safeguard® in the U.K., and PATS in Continental Europe. Passive means that it does not require any activity from the user.
The SecuriLock® System (PATS) is not compatible with aftermarket remote start systems, which allow the vehicle to be started from outside the vehicle. These systems may reduce the vehicle security level, and also may cause no-start issues. If equipped the remote start system must be removed before investigation of PATS-related, no-start issues.
Each encoded ignition key must be programmed into the vehicle's powertrain control (PCM) before it can be used to start the engine. There are special diagnostic repair procedures described in this section that must be carried out if a new encoded ignition key is necessary.
This system contains a new feature named Unlimited Key Mode. This feature allows a customer to program more than eight keys to the vehicle if they request it. Each vehicle in Unlimited Key Mode is set up with a special Unlimited Transponder Security Key. This allows all the customer vehicles to share the same keys, but no other keys from outside can be used to operate the vehicles. For an individual customer, any randomly selected Security Key is acceptable. Refer to Unlimited Key Mode Programming in Key Programming Switch State Control in this section.
The PATS transceiver module communicates with the encoded ignition key. The module is located behind the steering column shroud and contains an antenna connected to a small electronics module. During each vehicle start sequence, the transceiver module reads the encoded ignition key identification code and sends data to the PCM.
The control functions are contained in the PCM. This module carries out all of the PATS functions, such as receiving the identification code from the encoded ignition key and controlling the engine enable. The PCM initiates the key interrogation sequence when the vehicle ignition switch is turned to RUN or START.
All elements of the PATS must be functional before the engine is allowed to start. If any of the components are not working correctly, the vehicle will not start.
The PATS uses a visual theft indicator. The indicator will prove out for three seconds when the ignition switch is turned to RUN or START under normal operation. If there is a PATS concern, this indicator will either flash rapidly or glow steadily when the ignition switch is turned to RUN or START. The PATS system also flashes the theft indicator every two seconds at ignition OFF to act as a visual deterrent.
The PATS will be activated and will disable the vehicle from starting if there is a:

• incorrectly encoded ignition key
• damaged encoded ignition key
• unprogrammed key
• non-encoded key (key has no electronics)
• damaged wiring
• damaged transceiver
• damaged PCM
