You are right.Its the key code problem. As per the manual it says:--- sometimes when the battery is disconnected or has to be recharged - this happens. The computer forgets the key code and the key has to be re-coded. The ford service center/dealer charge $35 to $50 for recoding the key and this makes the car to function properly and it starts . ---------------- Also check the code in your car:--- under the plastic-passenger side under the very back window-next to rear passenger door jam-Looks like a black box. The Original Code is on a tag on that box.But if its not there then dealer is other option/.It takes few minutes to get recoded.----------------This should help.Thanks.Helpmech.

2004 Mountaineer no start no crank? Battery, starter, fuses, relays all good. No code errors. PATS problem. Original keys&fobs all good even reset manually and good. All dash lights functions ok.


. quick flashing when ? when trying to start the vehicle ? If yes you need to have it checked for codes . Do you know what DTC'S - diagnostic trouble codes are . If that light is flashing while trying to start the vehicle codes are present in the module that controls PATS . Instead of guessing have towed to a qualified repair shop . Because you have no idea how to diagnose this system .

My boyfriend replaced the key cylinder and steering column has a box It has wiring I need a diagram or how to wire it 1998 ford expedition xlt it cranks but doesn't start.??


That box is for the anti-theft system , he changed the lock cylinder . You need new PATS keys . PATS - passive anti theft system .The transceiver module communicates with the encoded ignition key. This 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 the data to the instrument cluster.
And the dealer is the only one that can program the keys . or a mobile lock smith .

Hi Eileen , How do you know your having a anti-theft system problem ? Any lights flashing when you try to crank the vehicle ? The engine does not crank over ? If it is a anti-theft system problem ,disconnecting the battery is not going to do anything except lose some learned setting's in some control modules . There are a few thing's you can check but if none of these are the problem your going to have to have it towed to the dealer ! It'll need to be checked for DTC'S - diagnostic trouble codes !
PATS disables the vehicle from starting if there is:
  • a damaged PATS key.
  • a non-programmed PATS key.
  • a non-PATS key (key has no electronics).
  • damaged wiring.
  • a damaged transceiver.
  • a damaged instrument cluster.
Inspection and Verification
  1. Verify the customer concern.
  1. Visually inspect the following for obvious signs of mechanical or electrical damage.

  • Large metallic objects, a second passive anti-theft system (PATS) key on the same key ring as the PATS key, or electronic devices on the key ring that can be used to purchase gasoline or similar items
  • Ignition lock cylinder

  • Use of a non-PATS key or incorrect PATS key
  • More than one PATS key on key ring
  • Remote start system installed

2004 explorer will not start, PATS light blinks normally, but when key inserted, blinks faster.


First get safety glasses,put vehicle in park,set parking brake.,BLOCK WHEELS....Disconnect negative battery cable for 10 seconds to reset computer system....reconnect cable..make sure all fuses/relays are operable..make sure it has fuel in tank...Turn ignition and listen for fuel pump to engage..If all works well try to start it...If not..get a long..2 or 3 foot jumper cable to by-pass ignition system..have a helper to turn ignition switch on but do not try to start it..Be safe..get under vehicle..,attach jumper wire to hot post at starter and small S-wire at top of starter solenoid..make sure alligator clips are tight...As soon as you touch them it should crank....If it does the problem is in ignition system.....YOU HAVE TO STAY CLEAR OF FAN AND ALL MOVING BELTS AND COMPONENTS WHILE UNDER VEHICLE !!!.......If no luck write me back.....BROOKS....

2004 explore won't start or crank, it does nothing when starting. I replaced starter and battery and getting same results.


Is your security light flashing--if yes, you have a PATS problem. If no, try starting in neutral or shifting thru the gears as you hold the key to start (foot on brake, please). This will test the adjustment of your park/neutral switch.

Please see my tip at http://www.fixya.com/cars/r6222268-engine_doesnt_crank_turn_over . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

2004 Ford Explorer won't start. Think we need to


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
