If the key and the fob have separated, you should still be able to start the car by holding the fob near the ignition when you start the vehicle. This will allow your car to read the immobilizer code from the chip in your fob. You can do this temporarily until you can get a new key. Once the car starts, you can move the fob away - it only needs to be there while starting the car.

Car wont start light blinking


The red light flashing is telling you that the security circuit has not recognised your key chip so it will not start. Either there is a fault on the reader or you have dropped your key and damaged/lost te chip.
Ring an auto locksmith. They will quickly cut you a set of keys and code them to your car.
Always keep a spare key handy.

Bought 2012 Fiat 500 Pop that has front end damage. Key stuck.


To remove the key, you take off the steering wheel covers. Underneath, there is a red tab to push in. Push in the red tab and remove key. Fuel cut off is your next problem. You use your directionals to reset the airbag module to turn on fuel. The procedure is listed in the owners manual under " in case of accident"

It still sounds like a passkey or theft deterrent issue. The check engine light is most likely a B2865 or B2860 code for an invalid key, likely related to the ignition switch being replaced. The passlock sensor is inside the ignition switch, and could have been damaged during install. Try just turning the key on and watch the security light, if it starts to flash after a few minutes, keep the key on for 10 minutes (or until it stops flashing). Then retry to start. You may have to have it scanned for further diagnosis.

What does it mean when the airbag light comes on?


Either the sensor in the bumper has lost communication with the airbag module, or the airbag module is bad, or the airbag package itself is damaged somehow.

Have you tried cycling key for fault codes? Turn ignition to on (not start) then off, then on, then off, then on, leave it on, and count flashes of check engine light.
flash,flash,pause, flash flash, is code 22. 3 flashes, pause, then 5 flashes, would be code 35, etc. See what you get, & get back to us with them if you need more help.

My 1998 ford expedition won t start and the theft


the light blinks when the system is armed. Normal.

Your key has to be able to communicate with the receiver in the ignition area. Does your other key work ok?

Anti-Theft The passive anti-theft system (PATS) 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 PATS module.
  • If the key's ID code has been programmed into the system, the vehicle powertrain control module (PCM) (12A650) is allowed to operate; this allows the vehicle to start.
  • If the key's ID code is not programmed into the PATS module, or if no encoded key is detected, then the vehicle PCM is disabled.
The PATS module, located under the driver side instrument panel, communicates the state of the security system to the PCM via the module communications network. The PCM, based on the communications from the PATS module, will determine if the vehicle's engine will be enabled to start. If the PCM prevents the vehicle from starting because of PATS, the PCM will store a DTC in memory.
-------------------------------------------------------------------------
The anti-theft vehicle protection system utilizes the THEFT indicator, located in the instrument cluster (10849), when the ignition switch is turned to the RUN/START position. The indicator provides system prove out and operating status to the customer or technician.
Each PATS ignition key holds electronics that give each key a unique ID code.
The PATS will activate the indicator signal when the ignition switch is turned to the RUN/START position. The THEFT indicator will turn ON for two seconds, then turn OFF.
If the THEFT indicator flashes for one minute or more, this indicates that there was no key code received.
When the vehicle ignition switch is placed in either RUN or START, the PATS module requests the ignition key ID code. The PATS module requests the ignition key ID code by supplying power, ground, and the carrier signal to the transceiver to energize the ignition key. After the energize period, the key transmits its ID code to the transceiver module, which sends it to the PATS module.
The PATS module then compares the received KEY ID code to those stored in memory (16 maximum). If the ID matches, the PATS module sends an enable signal to the PCM over the module communication network.
The passive vehicle protection system utilizes the engine management capabilities of the PCM to enable or disable the vehicle engine. The module communication network is used to send and receive messages to and from the PCM.
Within one second after engine start, the PCM must receive an enable signal from the PATS module through the module communication network or the engine is disabled before the vehicle can be moved.
If the PATS module recognizes a stored ignition key code but there is a module communication network concern preventing the PCM from recognizing the start enable signal from the PATS module, the vehicle engine will be disabled. If this happens, the PATS module will flash the THEFT indicator for one minute, then flash diagnostic trouble code 16 ten times to indicate there is a problem with the module communication network circuits or the PCM is not responding properly.
The passive vehicle protection system will disable the vehicle from starting if there is a:
  • Damaged encoded key.
  • Unprogrammed key.
  • Non-encoded key (key has no electronics).
  • Wiring concern.
  • Transceiver concern.
  • Control module concern.
  • Module communications network concern.

My 2000 Ford Taurus will not start because of the security system


the security system resets itself after about 15 minutes. If it was the security system, the car would not crank over. Why do you think it's the security system?
do you have gas in tank?

Is it a Ford security system, with the flashing light on the dash?


Principles of Operation
The PATS uses a specially encoded ignition key, this key is not compatible with previous vehicles or any current model year vehicles. Each specially encoded ignition key contains a permanently installed electronic device called a transponder. Each transponder contains a unique encrypted identification code out of over 18 billion, billion combinations.
Each encoded ignition key must be programmed into the vehicle's powertrain control module (PCM) before it can be used to start the engine. There are special diagnostic repair procedures outlined in this manual 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 their 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 Key Programming—Unlimited Key Mode in this section.
The PATS transceiver module communicates with the encoded ignition key. The module is located behind the steering wheel 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 problem, 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:
  • improper encoded ignition key (example — Taurus/Sable key).
  • damaged encoded ignition key.
  • unprogrammed key.
  • non-encoded key (key has no electronics).
  • damaged wiring.
  • damaged transceiver.
