SOURCE: flashing security light

if ur key has the security chip in it, it possible that ur ignition switch isnt reading that chip right away. i mean as long as u can get ur car started try and not get too worried about it. it is possible that ur ignition might be goin bad so try to keep an eye on it and if it starts to get worse take it in.

Replace ignition lock cylinder. The wires have broken that go to it.

Check the batteries in your car key if its electronic. If it has a RFID in the key that can stop the car from working because it is a security device.

SOURCE: can not start car security light flash fuse ok

had same problem in 99 aurora. fixed it here

http://mattwindsurfs.wordpress.com/2007/12/30/gm-pass-key-ill-pass/

from the above site:

It worked well for me for about ten years, but I finally got fed up with not being able to start my own car with my own key. I don’t like to get screwed on car repairs, so here’s what happened. I used Google for a while and found some websites with more information than I really needed, and I read it all. If you are having the same problem, you have probably figured out what is going on. You turn the key. The car doesn’t start, but the ‘SECURITY’ indicator blinks. You give up, and it stays lit. You know that the little resistor in the key is not making good contact. You can go Google for those other sites as well, but you really don’t need all the information they give. I had been putting off the job because I thought I was going to have to crack open my steering column. This was not the case. Here’s how it worked on my 97 Camaro:

  1. Go to the electronics store and pick up a cheap multimeter. Open the box in the store and try to read your key with it. Quickly discover that this one is a total piece and you shouldn’t have wasted your money on it. Good thing you didn’t. Close the box and spend $50 on a real nice overkill version with auto-ranging. It’s still less than the $500 model.
  2. Leave the store and measure the resistance of the key in the peace and quiet of the hurting car. In my case it’s 886 Ohms. I’m no expert, but I bet GM picked values that don’t match up with widely available resistors.
  3. Well the store has 820. Will it work? I didn’t have the table I found online with the ranges about each of the 15 possible values in pass key. That’s OK. 1/(1/8200+1/1000) = 891. This is the resistance of an 8.2 kOhm and a 1 kOhm resistor in parallel. Don’t make this as hard as I did. Bring a calculator, or at least a pen. Buy the resistors and a 40W soldering iron.
  4. Here’s the action: twist the leads on the resistors together and solder them. Get down under the steering while and take all the screws out of the trim. Pull pretty hard on the trim to get it off.
  5. Literally the first thing you see is an orange wire coming out of the bottom of the steering column, housing two white wires. It’s plugged into another pair. One is black and white, and the other is purple and white. That pair is the car side. Cut it. Strip the ends and jury-rig twist the strands around the ends of the resistor.
  6. Try to start the car. It works. Try to start it again. It works again. Sweet. If it doesn’t work for you, go back to math and maybe buy more resistors. Better to get it close the first time.
  7. Solder each end of the newly-parallel resistors to one of those wires. Let the orange wire hang. Ensure a good solder job so there won’t be problems in the future. Wrap the whole thing in electrical tape and put the trim back on.
  8. Start the car again it works. Try again. It works again.
This is much better than having to try 6 times, waiting 4 minutes between each attempt, when I’m already late for work. I am thrilled to know that when I go to start my car tomorrow morning it will not be a 50/50 chance.

SOURCE: Security light on and flashing, reads key code...

Looks like the TDM in the security system (VATS/PassKey) is having problems, it's typical on those cars and it can get worse till the car wont start anymore. You can find a great write-up here: http://newrockies.ca , it was the only thing that saved my Park Avenue.

2003 LINCOLN TOWN CAR WONT START, HOW DO I DEACTIVATE SECURITY SYSTEM


When you turn the key to run or start is the theft light on or flashing ? Sorry but their is no deactivating , it's software programmed into the vehicle control systems . The dealer couldn't even do that with a factory scan tool . You need to see what DTC's - diagnostic trouble codes are stored , diagnose the problem and fix it .

How to program my key to 98 ford explorer


for Ford keys (1996 -early 1998 Ford, Lincoln, Mercury)

If you want to initiate a new master key....

1. Insert new key into ignition cylinder and turn it to the ON (RUN) position. The security light on the dash will flash for fifteen minutes.


2. When the security light stops flashing, you have FIVE minutes to start the next step. Turn the ignition cylinder OFF and then back to the ON (RUN) position. The security light on the dash will flash for fifteen more minutes.

3. When the security light stops flashing, you have FIVE minutes to start the next step. Turn the ignition cylinder to OFF and then back ON (RUN) position. The dash will flash for fifteen more minutes.

4. After the security light stops flashing the third time, the new key has been programmed into the vehicles computer and will operate the car. It has replaced ALL the previous electronic key codes and is the ONLY key programmed into the vehicles computer.
If you want to add a key....


1. Insert an existing key into the ignition cylinder.


2. Turn the ignition cylinder to ON (RUN) and back to OFF.

3. Remove the existing key and, within 15 seconds, insert the new key and turn it to ON (RUN).

4. The security light will light up for two seconds to indicate success in programming the key into the vehicle.

5. Don't attempt to start the vehicle with any key for at least 1 minute.
<HR>On-Board Programming Method "C"


for Ford keys (Later 1998-newer Ford, Lincoln, Mercury)

If you want to initiate a new master key....

1. This requires that the vehicle be connected to special dealer equipment. There are two ten minute delays involved while this device erases all existing key programming and sets up the vehicle computer to accept new key codes. Two new keys should be ready because the system requires a minimum of two keys in the program. After the first two keys are programmed, additional keys can be entered individually by following the instructions for adding duplicate keys (below).

If you want to add a key....


**You must have two original keys to perform this procedure. If you only have one key, you WILL have to take it to the dealer to get it programmed**


1. Insert and existing (working) key into the ignition cylinder.

2. Turn the ignition cylinder ON (RUN) and back to OFF. Ignition should stay on for at least ONE SECOND.

3. Remove the existing key and, within TEN seconds, insert a second working key and turn it to ON (RUN) and the back OFF. Ignition must be in ON for at least ONE second, but no more than TEN seconds. Remove the key.

4. Insert the new key before TWENTY seconds have elapsed and turn it to ON (RUN). Leave it the ON position for at least ONE secondand turn back to OFF.

5. The security light will light up for THREE seconds to indicate that the new key has been successfully programmed.

6. To program additional keys, repeat steps 1 through 5
As a precautionary measure for all of the above procedures, you should wait at least one minute after you have performed this until you start your vehicle.

On my 2001 Lincoln ls 3.9 security light on dash still flashing rapidly for a minute then pause 1 flash pause 6 flashes with key on. Now when I put key in ignition the rpms and speedometer gauges star


Well I am a certified mechanic and I would pull the air cleaner housing open the throttle shoot some carb cleaner in it and if it starts even if only for few seconds your fuel pump is bad. If it doesn't than you need to scan the car with a scanner for no start codes. You can rent a scanner at most automotive part stores for a deposit and when you return it undamaged you get your money back. Usually costs nothing. But if you don't have any pressure on the fuel rail that is most likely your problem. You can clear all the dashboard codes and lights with a scanner if they don't straiten it out on its own. Disconnect battery for a few minutes sometimes that will clear old codes. Only clear codes if you have found out that the fuel pump was bad otherwise you'll need them codes for figuring out the no start problem. Bryan ASE master certified mechanic.

2002 Lincoln navigator won't start the anti theft light just keeps blinking what can I do


Disconnect the battery cable and leave disconnected for 5 to 10 minutes. Reconnect cable and see if this resets the security system. If light is not flashing, then it should have reset. If when trying to start and the theft light comes on again, have your key checked to see if it has lost its code. If you have a second key, try using it. If this does not work, you may have to have the system flashed at the dealership.

Security light flashes and won't start 02 lincoln ls


How old & what condition is the battery,on an LS
they only seen to last 4.5 years

Try only one Ford- approved PATS key that is programmed & you know has been working & nothing else nearby, such as a key chain
with other objects


Does the LED indicator flash rapidly or glow steady for 3 seconds,
with key in Run or Start ,if so, you got problems & will need a scan tool to get the codes,not a code reader.


Does the starter turn over the motor?


Need at least 2 keys programmed to system


You got at least 7 fuses to check on 2 of the 3
junction blocks (fuses)

Hi, I found this on a ford forum for you, procedure to program a new key to your car's anti theft system computer.:

How to program a replacement PATS key patskey_small.jpg

Please keep in mind....
This and other how-to articles are provided for informational purposes only. Perform the procedures at your own risk. FordF150.net is not responsible for any damage that may occur as a result of performing procedures outlined in any article. Please be sure to read and understand the entire article before doing this.

These instructions will save you a lot of money. The dealer wants at least $50 just to do this simple procedure.....

To start off, I'll explain a bit about what a PATS key is, what it does, and why this might concern you.

PATS is an acronym that stands for Passive Anti-Theft System (Ford also calls this SecuriLock). It is also called a transponder key. It is a security feature found on most (if not all) new Ford products, and what it does is disable your vehicle's starter unless your specially programmed key is used to start the vehicle. There is a computer chip inside of the key, and without that you will NOT be able to start the vehicle -- even if you have a regular (non-PATS) key with the correct cuts, it will not work.

For convenience, I'm also including a list of other vehicles that these instructions apply:

Ford Contour '98-up
F-150 '98-up
Ford Crown Victoria '97-up
Ford Escort 99-up
Ford Excursion '00-up
Ford Expedition '98-up
Ford Explorer '98-up
Ford Focus '00-up
Ford Mustang '96-up
Ford Ranger '98-up
Ford Taurus '96-up

Ford Windstar '98-up
Lincoln Continental '98-up
Lincoln LS '00-up
Lincoln Mark VIII '98-up
Lincoln Navigator '98-up
Lincoln Town Car '98-up
Mercury Grand Marquis '97-up
Mercury Mountaineer '98-up
Mercury Mystique '98-up
Mercury Sable '96-up

NOTE: These instructions may apply to more or less vehicles than those listed above. I cannot confirm that these procedures work for every year and model listed. See your dealer if to confirm this.

That is not a code, It is a GET ME CHECKED OUT SOON attention flash. If you hacve an AutoZone auto parts store in you r towm/area, go to them and ask them to put the code reader on the car. Then ask them to make a list of the codes and the definitions. Advice can be given better then. Hope this helps you along a bit.
