Anti-theft system problem

The anti-theft system will not reset. The electrical system locked out, there are no bulbs lit inside, and the car will not start.
Experienced mechanics share their insights in answering this question :
It sounds like the battery is not powering the vehicle and would need to be checked. If your battery voltage falls below 9 volts, then the anti-theft system may think a break-in is happening, and it will lock out until the battery is on, and the correct key is used. I recommend having a mechanic, such as one from YourMechanic, check this out for you to identify and quote the repairs needed. The starting system and charging system should be checked first.

Disarming the Alarm

Disarm the alarm by any of the following actions: Unlock the doors or luggage compartment with the remote control or keyless entry keypad. Switch the ignition on or start the vehicle. Use a key in the driver`s door to unlock the vehicle, then switch the ignition on within 12 seconds.

Put the key in the ignition and rotate forward two clicks to the “On” position that makes the dashboard light up, but don`t try starting the car. Leave the key there for 15 minutes; it doesn`t always take that long, but it can. After that time, check to see if the anti-theft light has gone out, if one was lit up.
The system arms when you lock your vehicle. When armed, the alarm is triggered in any of the following ways: If someone opens a door, the liftgate or the hood without a valid key or remote control. If you switch your vehicle on without a correctly coded key.
If your ECU controls the anti-theft system, disconnecting the battery may lock you out of your car. Like desktop computers and most other electronics, disconnecting the battery cable for a short period will not fully reset your ECU due to the residual power remaining in the circuits.
There are some cars that will recognize the key from you simply turning it back and forth in the door`s cylinder. It is best to try both methods: holding the key in the door, as well as turning the key both ways to disable the anti-theft system.
A car`s anti-theft system may activate if your key fob battery is dead and hasn`t disabled the system. 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.
It can be difficult to manually turn off your car`s anti-theft system if you don`t have a key fob, but it is achievable. If there are no obvious little buttons or levers on the ignition cylinder that could disarm the device, try gently wiggling the key inside the cylinder; this might be enough to do it.
The Radio Anti-Theft Code, or Dodge radio code, is a five-digit number that is used to reset your radio once it has been disconnected from power. The idea of this feature is that thieves would not be able to use a radio after taking it because of the need for a code; this was designed to reduce stereo theft.
A car`s anti-theft system may activate if your key fob battery is dead and hasn`t disabled the system. 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.

While diriving my 2017 honda civic my dash displayed powered steering (eps) problem, what does this mean?
ANSWER : Yes, all of those issues should be checked out, especially as the warning lights involve key vehicle safety systems like the steering system. Your vehicle is under warranty as it is brand new. You should bring the car back to the dealer and have them resolve the issues at no cost to you. If the issues recur, be sure to follow up, as needed, and if the issues are not permanently resolved, in a reasonable number of visits to the dealer, keep in mind that very specific, and very protective (of the consumer) state and Federal Lemon laws apply to new vehicles. I mention all this because you are driving a brand new car and yet all these warning lights have appeared. That’s not an expected outcome and thus you should follow-up promptly and make sure this gets fully and thoroughly resolved. If you have further questions or concerns, please do not hesitate to re-contact YourMechanic as we are always here to help you.

ANSWER : Hi there, thanks for writing in.

It sounds like you are having a serious electrical malfunction, which is very hard to diagnose without being able to look at the car first hand. The first step to diagnosing your electrical issue would be to scan all the relevant control modules in the vehicle, to see if there are any faults relating to any of these issues. It sounds like somebody at the dealer has been trying to fix this problem, so it may be a more involved one. I have personally seen failed control modules cause things like this, but that is no guarantee that it’s the problem in your case. It would be best to have a qualified independent technician, such as one from YourMechanic, look at your car to diagnose your electrical problem.

Electrical or transmission problems with Hummer
ANSWER : Hi there. This vehicle is known for having a history of electrical issues. From the symptoms you are getting it sounds like a bad ignition switch or a failing body control module. Most of the time it is the ignition switch. When it fails internally it causes these systems to act up almost like the key is being turned off and on. This can be diagnosed with a voltage meter by doing a voltage drop test on the switch. If the switch is fine then the body control module will need to be replaced. If this is something that you want to have diagnosed, consider YourMechanic, as a certified mechanic can come to your office to inspect your electrical problems.

Problem with securilock / PATS system is driving me crazy!
ANSWER : Your Escape can be diagnosed and repaired without having to be at a Ford dealer if that is your preference. Your symptoms can be caused by: electrical interferences such as AC voltage coming from a faulty alternator, or an ignition related misfire.

The battery should be tested and verified as good. Battery cables, connections, and grounds all need to be checked to ensure that they are clean and tight. Aftermarket electrical accessories, like an alarm, can be the cause. Using a scan tool to check for PATS-related or any other diagnostic trouble codes is indicated.

I’d recommend getting some help from a qualified technician who can diagnose your electrical issue and fix it accordingly at your home or workplace.

System Emissions Problem
ANSWER : Hey there. With the vehicle being brand new, typically there is a warranty and you can take it back to the dealership. The sensor may have failed. If resetting it had an effect on the light, then that means the same issue has triggered again, or the sensor was faulty to begin with. The catalytic converter would be a concern if the warning light indicated a code pertaining to the lower oxygen sensor.

The best way to tell is to have the vehicle scanned for the codes that have set the warning light off. The components related to the codes would be the first components to test is possible. Any warning light should be taken seriously. However a Check Engine Light would indicate a more serious issue.
