You need to have your key reprogrammed. even a plain spare key will set off the alarm if it does not have a chip programmed with the same code as the anti theft system.

SOURCE: Anti-theft indicator keeps flashing when

Yes it flashes to let others know you have an alarm on the car and not to mess with it! Yes. It should blink when the key is not in the ignition. This lets you know that the Passive anti-theft system is on. What this means? Basically the key you use has a specific code that coordinates with your car, and that key is the only key that will work for your car out of a possible 70 quadrillion codes or something like that. The light is used to help scare away thiefs that would break into your car, no car alarm will go off if they do, but most run of the mill car thiefs wont take the chance of breaking into your car if they think there might be an alarm on it. If the light blinks while the key is in the ignition then you shouldn't be able to start the car. It's normal for it to always flash. The only time it won't is with the car running.
If this was helpful a vote with the thumbs up would be greatly appreciated.
Thanks

Either you may be using a key that you had copied from the original or your chip went bad in your original key. Most of cars now a days have the key censor in the key so if it is the incorrect key it will not start your car or if it does not read that chip it will not start

2003 ford mustang gt anti theft light flashing engine will turn over but will not start


From my experience...
A non PATS coded key SHOULD not turn the STARTER...!

If ANTI-THEFT were invoked... you can attain a not start condition which the Owners Manual says must be cleared by the dealer.

A working PATS key should disable the anti theft... by turning the ignition on... ELSE try your other key.

The SecuriLock [PATS]
passive anti-theft system is not compatible with
non-Ford aftermarket remote start systems. Use of these systems may
result in vehicle starting problems and a loss of security protection.

Could anti-theft system d mustang cause car to shut off while driving?


Hi, im a retired ford tech, with alot of experience on ford anti theft . Now if you are asking about a built in oem factory anti theft, your not going to be able to bypass it. Now to answer your question, I would say your factory anti theft IS NOT causing your issue. It will make it unable to start,it doesnt kill anything else.

2000 mustang gt. The theft light is on and wont


When the car is off, a slowly flashing anti-theft light is normal. When the key is in one of the on positions, that light should go off. If it thinks it detects a theft condition, the light will flash quite rapidly and prevent starting. You can also check the mileage readings in the odometer display. If you see dashes instead of numbers, that is a clue that some part of the onboard computer has gone wacky.

You already tried one of the steps that I would recommend (unlocking the door, though that may not be enough by itself. Here are a couple of things to try.

First, pray that this isn't the anti-theft computer gone awry. That is uber expensive to replace. Following that prayer ...

Verify that the battery is fully charged and showing about 12.8 volts with the headlights off and about 12 volts with headlights on. If the voltages are low, try jumping the battery to see if you can get it to start. (A low battery can occasionally cause an anit-theft fault.)

If you have another key, try that one. The chip in the first key may have gone bad. If that doesn't work ...

Disconnect the battery negative cable for 5 minutes. Reconnect, and lock and unlock the doors several times with the remote. Check to see if the anti-theft light is still flashing rapidly. If not, try starting.

Anything more than these steps will need to be handled by a qualified shop. (For example, a wire in the steering column could be damaged by the tilt mechanism, or the computer malfunctioning).

Good luck.

2004 mustang won't start because of anti theft system


Did you check the battery of the car (maybe loose cable)? but if it just happen suddenly, it might be your altenator that wasn't charging your battery. I think once there's enough power gone through the car then your anti-theft system should work as normal again.

Have a 98 mustang v6 that just replaced the starter, alternator and last the fuel pump, everything back together now when try to start up, anti theft blinks crazy and tries to turn over but will not catch,...


This is from the Ford manual:


When the ignition is turned to RUN or START, the

theft indicator will light for 3 seconds and then go

out. If the theft indicator stays on for an extended

period of time or flashes rapidly, have the system

serviced by your dealership or a qualified technician.

Anti theft system


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.
