Hi there. What had happened is the wrong key set the security to the vehicle. This is to prevent the vehicle from starting with the wrong keys. Try removing the battery cables (+) and (-) for 13 minutes. During that time, put the original key in the ignition and turn it on. Activate everything in the car even though there is no power. Then remove the key and hook up the battery cables. The computer should have reset and reset the security. If the security is still being tripped, then I recommend seeking out a professional, such as one from Your Mechanic, to help you
How to Identify and Fix Common car Problems ?

To reset the anti-theft system on your Chevy Malibu, get in the car and turn the electrical system on with your key or key fob, but don`t start the engine. After a few minutes, the anti-theft light will go off, and you should be good to go!
The most common reasons a Chevrolet Malibu key won`t turn are a binding steering column/lock, an ignition switch issue, or a problem with the ignition key.
A faulty key fob is an inconvenience that can throw off your whole schedule. While it may seem far-fetched to think of your fob as needing regular maintenance, your key fob is not something to overlook because when it fails it can stop you from being able to enter your vehicle at all, let alone start the engine.
You can try giving the car time to re-recognize the key. 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.
If the car cranks when you turn the key, but the engine won`t start, it could be because fuel isn`t getting to the engine. One potential reason for this could be dirty fuel injectors. Over time, the fuel injector nozzles can become clogged with rust, corrosion or debris.
Fortunately, this is often an easy fix. Simply grab a can of WD-40, silicon-based lubricant, graphite spray, or a dry lubricant and spray it into the keyway. Once it has been sprayed, insert the key so the lubricant will work into the locking mechanism.
If the security or anti-theft light is flashing when you attempt to start your car, and the engine does not crank or does not start, you have an anti-theft problem. The system may not be recognizing your key or keyless entry signal, or there may be a fault in the anti-theft module, keyless entry system or wiring.
Reasons A Car Won`t Detect the Key Fob
Keyfob Battery – The battery inside your key fob is dead or too weak. Therefore, it can not send a strong signal to the keyless entry system. Key batteries will need to be replaced. Damaged Key – The key itself is damaged, which can happen when you drop the key or wash it.
The most common reasons a Chevrolet Malibu won`t start are a dead battery, an alternator problem, or failed starter. Search our network of RepairPal Certified shops near you to speak with a technician about your issue.
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.
Passive anti-theft devices include: An alarm system that activates automatically when you turn the ignition off or shut your car door. Automatic disabling devices such as a computer chip in the ignition key. This device will prevent the car from starting if an unrecognized key is used.
The Interior Movement Sensor monitors the interior of the vehicle with ultrasonic waves. If it senses movement or unauthorized entry, it can activate the vehicle alarm, which will trigger the horn, siren and vehicle lights as well as the Surround Vision Recorder, if equipped.
To work correctly, the ignition mechanism is powered by the battery. If the battery fails, the ignition will automatically get locked up. Then you won`t be able to pull the key out of the ignition. In this situation, the best thing to do is to wait for the battery to start itself or for a new battery to be fitted.
If the key won`t turn in the door lock, the problem could be dirt or dust in the cylinder causing the pins to be stuck in a partially raised position. If that`s the case, it may be an easy fix. You can spray dry lubricant into the keyway and then insert the key a few times to get the lubricant working.
The bad engine immobiliser won`t let the vehicle start until it does not receive a proper security token. In some cases, you might be able to lock or unlock the vehicle but the engine will not start with a faulty engine immobiliser.
The anti-theft system may lock the wheel and prevent the key from turning in its slot. It occurs most often when you turn off the car and attempt to move the steering wheel. The next time you turn the key in the ignition, the car will start with the wheel fixed in that position.
Typically, the fob contains a chip that identifies radio signals sent by your vehicle. These signals are only able to travel for a few feet. As you enter or exit the car, the vehicle sends a radio signal to the key fob. The fob responds by relaying its code to the vehicle.
If I change the battery in either the car or key fob do I have to reprogram the key fobs? No, The key fobs use non-volatile memory, meaning that they will never lose their programming if power to either the key fob itself or the module is lost.
Some of the most common include transmission problems, electrical issues, and interior accessory faults. Still, none come close to the damage the worst models might sustain. If you invest in one of these models, you can feel comfortable on the road.
Why won`t my car start but I have power? If you attempt to start up your car but the engine won`t turn over and the dashboard lights up, then you most likely have an issue with your battery. You could have a damaged or corroded battery terminal, which is stopping the engine from starting up when you fully turn the key.
Jump-Start the Car
Start the engine of the vehicle that`s donating the electricity. Then start the car with the weak battery. If the engine doesn`t turn over right away, you might need to wait a few minutes to allow the battery to build a sufficient charge.
The software upgrades certain Hyundai vehicles equipped with standard “turn-key-to-start” ignitions so they cannot be started without their keys when subjected to the popularized theft method.
Car alarms rely on the electronic component of the vehicle, and disconnecting the battery should both silence the siren and reset your alarm. Open up the hood, locate the battery, and with a wrench, remove the negative terminal. Then reconnect it after a minute has passed.

My car will not start Intermittently. I purchased a new battery 2 weeks ago and yesterday the car wouldn’t start. Got a jump and
ANSWER : The issue you are having is probably due to an intermittent fault in the starter motor itself or a deficiency in the starter electrical circuit, for example a large voltage drop due to a poor ground or a high resistance connection. These issues can be readily diagnosed and resolved on a mobile basis if you request a hard starting diagnostic. If you request that diagnostic, the responding certified mechanic will get this resolved for you promptly. Based on Toyota’s Factory Service Manual, the battery should not be disconnected if the vehicle engine is running. The battery acts as a large resistive voltage sink and consequently taking the battery out of the circuit, while the alternator is still running, can create a voltage spike on the car’s electrical system which is not good for voltage sensitive components such as the engine computer.

how to fix no keys issue if i dont have the car’s keys
ANSWER : The 2010 Maxima uses the ’Nissan Intelligent Key" system. The only way to start the car is to have the key fob in the vehicle while using the start button. There is no way to defeat this requirement as this is part of the engine immobilizer system. If the key fob is lost, one can be procured from a Nissan dealer. If somehow your vehicle was equipped with a transponder chip key (instead of the Intelligent Key system), you must have a transponder chip that is programmed specifically to your vehicle. If you need the assistance of a Mechanic, dispatched by YourMechanic right to your location, please request an electrical component diagnostic and the responding certified mechanic will assist you in obtaining a replacement key fob or transponder key. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
New battery & fuel pump. Hours later car starts and shuts down 3X in a row. Finally it starts, 48 hours later, won’t start at all
ANSWER : Checking all the fuses was a good move. I would also want to put a scan tool on it and check for diagnostic trouble codes (DTCs) as well as seeing the data that the computer is seeing.
A fuel pressure test would be a good idea to verify correct pressure and so that you’d be able to eliminate that possibility. It should be 58psi on your Magnum.
I also recommend getting your battery tested (I know, it’s new, have it tested anyway) and be sure it’s charged to at least 75%. And yes, loose battery cable connections can result in electrical problems.
If you need some assistance with this, consider enlisting a certified mechanic who can perform the checks I’ve mentioned and diagnose your starting issue firsthand. The mechanic can then perform the necessary repairs once the problem has been isolated. Good luck.

car hesitates when trying to start the car ,but when started then i shut car off and start again it will start right up
ANSWER : Hi there:
Sometimes when you have problems starting an engine initially it is caused by a restriction in fuel flow; caused either by clogged fuel injectors or the throttle body that needs to be cleaned. Once the fuel starts to flow and engine warms up, it’s much easier to start. However, it could also be an air filter, EGR valve or other components that causes this issue as well, which is why it’s best to have a professional mobile mechanic complete a car is hard to start inspection so they can pinpoint the source of this issue.
Car Won’t Start
ANSWER : Hello. From what you describe it would appear that your vehicle is having some sort of malfunction with the security system. It may be possible that the security system is enabled and preventing the vehicle from starting. This may or may not be related to the the recent battery replacement for the remote, or it could also be related to the EPS light. The EPS light comes on when the computer detects an issue with the vehicle’s electronic power steering system. There are cases where a steering malfunction will prevent the vehicle from starting, if the issue detected is serious enough to significantly affect the vehicle’s handling. It is unlikely that the brake fluid or engine oil are related to the issue, but it would not be a bad idea to make sure that they are topped off. I would recommend retrieving the trouble codes that are setting off the EPS light, as they will likely reveal some information on what the issue may be. Also keep in mind that a no start condition can be caused by other things, such as issues with the ignition system, or even the starter itself. As these sorts of electrical issues can sometimes be difficult to diagnose, I would recommend having a professional technician, such as one from YourMechanic, come to your location to [diagnose the cause of your warning light, and if it may be related to the no start condition.
2005 Chrysler 300C changed battery and alternator. Car started, ran, and then battery light came on. Shut car off and wouldn’t start.
ANSWER : Hi. There is a couple of things that could be wrong here. The battery or alternator that was just installed could be defective. Theses parts need to be tested for proper operation. There also could be a fuse, fusible link, or wiring for the battery or charging system that is blown or broken causing the battery light to come on.
The codes that you have will cause the car to shut down, run rough, or not start at all. The crankshaft sensor and camshaft sensor should be replaced. I suggest having a certified technician from YourMechanic come diagnose the charging system and check engine codes to help you proceed with correct repairs.
