Car can’t start, car doesn’t recognize the key. 2013 Nissan Leaf

The car has a low mileage of around 29,000 miles. I've been experiencing some electrical issues lately. I had the battery checked and it is properly charged. The main issue is with startup. The dash has been showing a warning, which indicates that the key isn't being recognized by the car. There has also been some problems with the windows and doors malfunctioning from time to time. Occasionally, I wouldn't be able to unlock the doors or the windows wouldn't roll down. What could be done concerning these issues?

The most common reasons a Nissan LEAF 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.
What to Do if There is No Key Detected in a Nissan Key Fob. Even if your Nissan fob battery is still good, there may be an instance where the vehicle does not detect it. In most cases, the battery is likely either low or dead, but there could be an issue with your Nissan`s remote key functions.
Is your 2013 Nissan Rogue Key Fob not working properly, or isn`t working at all? It might be time to replace the battery, and while it`s open, take the time to clean out the inside. Fob batteries needs to be replaced every 3 years to work at maximum range and not sporadically fail.
Press and hold down the audio system power button for about 10 seconds until the Nissan logo appears, signifying that the reboot is underway.
Put the key into the ignition and turn it to “ACC.” Turn it off and take the key out of the ignition. Quickly repeat this process six times. When this is done, the emergency lights should flash twice. Put the key back in the ignition and turn it to “ACC” once again.
Can you start your Nissan if your key fob is dead? Absolutely! Learn all about the steps required for quick and easy Nissan key fob replacement now by reading our guide on how to change out a Nissan key fob battery!
Press and hold any button from your fob`s keychain until the door locks begin to flash. It should take about three seconds. Once you stop seeing the lock lights flash, you can release your programming button. You should then see a steady light that confirms that the key fob has been programmed.
If your remote starter isn`t working, be sure that you`re using the remote properly. If your remote starter system isn`t working properly, try replacing the battery in your fob. You can find replacement key fob batteries at Batteries Plus. Most remote starter fobs run on 2032 lithium coin cell batteries.
A bad battery in the key fob is most commonly the reason for a failure to send signals to the keyless entry system. If it is available, use the spare key fob to open the vehicle and start the ignition. If the spare fob is not available, use the provided key embedded in the fob to unlock the door.
Before you leave home or work, log in to the MyNISSAN app or MyNISSAN Owner Portal to remotely start your vehicle to return it to a comfortable temperature.
The Leaf has an alarm and an immobiliser, optimised to consume as little electricity as possible. In truth such electronics have so small a drain on the batteries that it makes no perceptible difference at all to have them active when away from the car, so there is little risk of them flattening the power source.
If your vehicle won`t start, it`s usually caused by a dying or dead battery, loose or corroded connection cables, a bad alternator or an issue with the starter.
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.
Possible causes of a power failure could be either bad battery connections, a bad ignition switch, or a bad alternator. What you need to do is check your vehicle`s power sources.

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.

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. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Car cranks but won’t start
ANSWER : Hi there. It sounds like the spare key isn’t being recognized by the immobilizer system. The method you stated that you performed sounded like the procedure to manually program the wireless fob portion to lock and unlock the doors. If the key isn’t programmed or the immobilizer system has lost the registration, then it will need to be completed and this usually has to be completed by the dealer. Unfortunately, Your Mechanic does not offer key programming services. Your Mechanic does have available technicians that come to your home or office to perform requested services, inspections, and repairs. Feel free to schedule your next service at www.yourmechanic.com.

ANSWER : 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

Car can’t start, car doesn’t recognize the key. 2013 Nissan Leaf
ANSWER : Hello there. This is a common issue with the 2013 Nissan Leaf. A few possible causes for this fault are the key fob failure, security module fault, a wiring fault, or a failing key fob battery.

Battery and oil light come on when trying to start car, take keys out try again car starts no problem and lights go away
ANSWER : Of course, don’t switch gears without being fully stopped, unless your Owner’s Manual or the manufacturer has alternative advice. However, the gear shift issue has no relation to the no-start problem you are describing. Inasmuch as you only have 6,000 miles on the car, the "constant on and off" that you believe has occurred is meaningless in comparison to the expected total vehicle service life. That is, assume what you perceive as "constant on and off", during merely 6,000 miles, might be equivalent to using the car "normally" for three years. A new car should be trouble free for at least 5 years, unless there is a defect, so your "constant on and off" is not a causal factor for any fault on the vehicle. What you might have is a defect in the ignition switch, or perhaps the immobilizer system, but if the problem is not in the switch itself, clearly there is an electrical problem.

If your vehicle is under warranty, by law the dealer MUST repair the issue you are describing within a prescribed time frame and number of "attempts", otherwise the dealer will run afoul of Federal and state Lemon Laws that give you very specific rights, and recourse (contact an Attorney; we are Mechanics, NOT attorneys). Consequently, if the vehicle is still under warranty, to save yourself money do be sure to seek a resolution from the dealer. If the vehicle is not under warranty, obviously a certified Mechanic from YourMechanic could identify the electrical fault and resolve this for you. If you want to go that route, please simply request a no start diagnostic -electrical system and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Charging warning light comes on when i turn the key and try to start the car and the car want start but when someone tried to give
ANSWER : Hi there:

If you recently replaced your battery, the issue may be caused by a malfunctioning alternator or other electrical component that comprises the charging system on your Nissan Sentra. The best way to find out which item specifically is faulty, is to have a professional mobile mechanic complete a car is hard to start inspection. This will allow the mechanic to determine the precise source of what’s going on with your Sentra and recommend or complete the right repairs.

Map sensor car won’t start up good ?
ANSWER : Your MAP sensor is an important input for your computer. It helps determine the load on the engine to calculate the correct amount of fuel to inject. It sometimes takes a few seconds for the vehicle to realize that the sensor is not producing a good signal.

At that point, it will use other methods to determine the fuel rate, such as pre-programmed fuel maps, throttle position, etc. I would suggest replacing the MAP sensor and retesting. If you would like to have it checked first, a certified technician from YourMechanic will be able to scan your vehicle and test components to determine the root cause of your starting issue before making a repair.
