Anti-theft systems are designed to prevent your vehicle from being stolen. These systems are constantly evolving. An anti-theft system may also integrate a car alarm or it might be just an engine immobilizer. This may be for many reasons including a dead car battery that loses its key memory or a dead battery in your remote. It could also be that your immobilizer chip is damaged in your key or the car door lock is damaged. Step 1: Check your key fob battery. Make sure the battery is installed correctly in your key fob.
If the battery is correctly installed, replace it with a fresh battery and try again.

Step 2: Check your door lock cylinder. If your car has been damaged in an attempt to steal it or break into it, the anti-theft system may have been engaged. Check for damage to the lock cylinder itself or under the door handle where would-be thieves may have punched through with a screwdriver. If the lock is damaged, try using the passenger side cylinder if your car has one. Step 3: Check that you are using the proper key to start your car. The key you are using may not have the chip required to start your car.
Step 1: Check for the anti-theft light. Step 2: Turn the ignition to the "on" position. Insert the key into the ignition and turn it to the on position, which activates your accessories but not the engine.
Step 3: Check the anti-theft light again. Step 1: Insert your key in the lock on the door. Step 2: Turn the key. Hold the key in this position for 20 to 30 seconds. This lets the system know you have the correct key, and it can allow you to bypass the alarm system.
Some vehicles recognize the key simply by turning the key back and forth in the door lock key cylinder. An anti-theft system that prevents your car from running properly is a nuisance, and while you may be thankful for it in the event of a crime, it is now causing you a great deal of inconvenience, which these steps have hopefully helped you resolve.

Related Models For Sale. Used Cars For Sale.Our automobiles have evolved over the years and are now an integral part of our lives. They have moved from being a luxury to a necessity today. Ford is one of the largest manufacturers of automobiles in the world, and one of the most popular brands in the industry.
Technology has grown multifold in the last two decades. It is now integrated into every machine we make today. Ford cars are no different. They are packed with technologically driven features, designed to make our lives easier. The anti-theft system is one such feature created to protect our vehicle from being stolen, as the name rightly suggests.
When the system detects that a person is trying to start the car by using a fake key or some other unconventional method, it ensures that the engine does not start by shutting the supply of power to the engine. Needless to say, this feature is key to the security of our carskeeping us free of worries. Could there be a problem with the key or is the technology malfunctioning? If the battery is drained out, the system is unlikely to read any method of trying to reset it.
Here is a useful guide to resetting anti-theft system on your Ford once you are sure that the battery is well-charged. When the anti-theft system is activated accidentally, most people suspect a faulty key.
While this could be a possible reason, it is a bleak one because the keys made by Ford are usually strong and sturdy. So, before you look to get your key replaced or repaired, try these simple steps to reset the anti-theft system of your Ford. This method uses the door lock of your Ford to reset the system. However, there could be damage to the key or its in-built chip. If neither method works, try them with a second key that you might have of the car. If the second key helps, your original key is at fault and you will need to get your key replaced or repaired.
However, the chances of this happening are bleak. If nothing is wrong with the key, check the door lock.How do i start my ford explorer after an idiot tried to steal it an destroyed the ignition cant afford mech an losing my job cause of this.
Gary answered 2 years ago. Unfortunately, there is no easy way to bypass the security system. It was put in place to prevent easy bypass to prevent theft. Anyone posting a way to bypass would diminish the security for all other vehicles. I feel for you but you will likely need a shop to fix it for you sorry.
A good thought, but dealer can't seem to find a fix; Towed it to shop in full failure mode, and they still were unable to fix it.
It eventually "fixed" itself. By "fixed" itself, do you mean it just suddenly started working, or was there a wink wink work around that you found that you don't want to post due to Gary's point about undermining the security feature? I finally got rid of my f, after towing it twice, to a Ford dealer. All I got was a call from sales mgr, offering me a trade in deal. That tells me, there's no fix for this failure.

Answers to pat's system! I exhausted myself trying to get my explorer system up and heres what i learned about pats. It cant be over ridden or "simply" bypassed i. Switched components, and did eventually get it going. Heres what you need to know. Pro thiefs have cpu's that are jail broken.
Simple swap in seconds. Unless someone swaped out one of these synchro systems and disrupted the flow of info, there should be no issue getting new keys programed which only needs to be done by dealer if you have no existing keys programed to the system.
So, nothing has changed, whats going on then and why did my key fail? Pull the rfid from the key, open the panel around the ignition and play with getting the rfid every angle and place around the rfid reader and wire loop around the ignition until theft light turns off and starts.
I found that for some reason mine only works one direction in one spot attached to the outside of the ignition chip rfid reader So i hot melt glued it on, havent had a problem since.
I did have to replace all the origional electrical in sync to that system Hope this helps. If there is no logical reason for a problem and theft light is on, you have an origional key and cpu and corresponding pat system components havent been damaged or removed, its the chip not reading.
Do what i did, then program more keys which is easy to diy! Good luck. Got rid of my f, Had a dealer sales type call wanting to sell me another vehicle. I bought another truck froma different dealer!
