The chip is in the key. Either the key has lost it's program or the transceiver is not recognising the key. Try another key if you have one.

SOURCE: 1999 ford winstar anti theft problem

Fords have a chip in the keys and a reader in the ignitions switch, when you insert the key and the theft light stays on solid then the key has passed. If the light flashes quickly then the key didn't pass the check and the vechicle will not start. This can some times be a key problem and some times a reader problem . But the keys can only be programed with a computer in this situation. The dealer or most lock smiths have these computers.

What is the exact location of the antitheft fuse box?


Explain anti-theft fuse box ! what do you think this is ? There is an anti-theft system on your vehicle , called PATS - passive anti theft system .Sorry , but there is not anti-theft fuse box .
Anti-Theft -Passive Anti-Theft System (PATS) The passive anti-theft system (PATS) contains the following components:
  • theft indicator
  • encoded ignition key
  • PATS transceiver module
  • powertrain control module (PCM)
  • standard corporate protocol (SCP) communication network

How do I reset the ProLock system?


Hi Carol , do you mean PATS passive antitheft system ? Locked up your car ,do you mean it won't crank over an start ?
The passive anti-theft system uses radio frequency identification technology to deter a driveaway theft. Passive means that it does not require any activity from the user.
  • During each vehicle start sequence, the ignition key identification code is requested by the vehicle protection anti-theft electronics.
  • If the key's ID code has been programmed into the system, the powertrain control module (PCM) (12A650) is signaled to enable the vehicle to start.
  • If the key's ID code is not programmed into the system, or if no encoded key is detected, then the powertrain control module is signaled to disable the vehicle.
The passive anti-theft system communicates the state of the security system to the powertrain control module via the J-1850 communications network data link connector (DLC). The powertrain control modulebased on the communications from the passive anti-theft system, will determine if the vehicle's engine is enabled to start. The passive anti-theft system differs from the active anti-theft alarm system in that the passive anti-theft system enables/disables the vehicle from starting and only operates with the ignition switch in RUN/START position. The active anti-theft alarm system has perimeter protection capabilities and operates only with the ignition switch OFF. Refer to Section 13-11A for active anti-theft alarm system information.
Vehicle Disabling The passive anti-theft system will be activated and disable the vehicle from starting if any of the following conditions exist:
  • damaged encoded key
  • unprogrammed key
  • non-encoded key (key has no electronics)
  • wiring concern
  • transceiver concern
  • Passive Anti-Theft System (PATS) control module concern
  • J-1850 Communications Network concern
  • Powertrain Control Module (PCM)

Fuse number eleven keeps blowing on 1998 lincoln conttenial what works that fuse


The equipment connected with this fuse is listed as the Ignition coils, the radio interference capacitor, the PCM relay and the passive Anti-theft System Module.

I think I would replace the PCM relay as it is the only part listed which has moving parts inside. In addition, you can check if the PCM relay is the same part as the Horn relay and use the horn relay in place of the former PCM relay. If your short goes away, then you know the old PCM relay was bad.

If the fuse breaks before you crank the engine, you could disconnect the coils and see if the fuse still breaks.

The radio capacitor, you need a little better diagram to identify this wire and when disconnected, you would know if the fuse breaks or not.

If its the anti-theft, then that is more complicated to solve. Test all the other stuff first.

Please let me know what you find.

2004 Mazda B2300 no spark after engine overhaul.


An anti theft light light is trying to tell you something. That thing is that the system will not allow the engine to start. Most systems shut off fuel and or ignition. Check and see if you have ground switching on and off for the injectors. If the anti theft system is shutting off the ignition then it will also shut off injectors/fuel system. Figure out the antitheft FIRST or you are probably going to chase you tail.

Heater fan not working - 30 amp HVAC fuse blows out repeatedly when replaced. Where should I look for root cause? Have dash disassembled, but can't see any bare wires anywhere behind radio/climate...


Try unplugging the blower motor, heater control unit and blower motor resistor. Replace the fuse then reconnect the items 1 by 1 and see what pops the fuse.

Bypass the theft deterrent module


The security light is a indicator that one of the parts of the antitheft system is failing, this then disables parts of the car due to the antitheft thinking that the car is being stolen. You may have broken something while turning the ignition when trying to learn your key fob. Did you make sure to pull the radio fuse before trying the key fob process? A lot of GM's 2000 to 2004ish ran the antitheft thru the radio. Its really hard to tell. Here is a link that explains the anti theft system. A lot of information and some ways to get around the system.

Here is what i found for reprogramming your key fob remote

1. Be sure ignition is OFF.

2. Remove RADIO fuse from fuse box. Fuse will be number 17 and located at LH side of instrument panel.

3. Turn ignition from OFF to RUN 3 times within 5 seconds ending in the RUN position. Off is the position where you can remove your key and Run is the position shy of starting your vehicle (do not crank engine or start vehicle). Be sure you are turning the key from off to run quickly.

4. Doors will Lock and Unlock indicating entry into programming mode.

5. Hold Lock and Unlock at the same time on first remote for approximately 15 seconds. Vehicle will respond by locking and unlocking doors indicating successful programming.

6. Repeat step 5 for each additional remote including working remotes.

7. Switch ignition off. Replace RADIO fuse. Test all remotes.

Security Light always on, door lock fuse keeps blowing


This is most likely a problem with your Passlock anti-theft system which is known issue with these cars. Passlock is a "passive" anti-theft system, which means that it will disable your ability to start the car if it thinks there is a problem. The three components that can cause this are: 1) Ignition Switch, 2) Ignition Cylinder, 3) Body Control Module (computer). The dealer is the only one who can solve this problem (unless you can bypass it, but it is not that easy). Estimated repair from most dealers is $800 and up.
