I’m sorry to hear that your Nissan Sentra is giving you trouble. The most frequent causes of a Nissan Sentra not starting are a bad starter, a bad alternator, or a dead battery.
Your Nissan Sentra won’t start or is having trouble starting for a variety of reasons. Even while the majority of the problems aren’t critical, if your battery entirely dies or your alternator stops functioning altogether, traveling without correcting them could leave you stranded.
The following are the most typical causes of a Nissan Sentra not starting:
- Key fob battery failure
- inadequate alternator
- Battery deterioration
- an inadequate or dead battery
- worn-out ignition plugs
- fuel pump malfunction
- defective starter motor
By measuring the voltage of your battery with a multimeter at home, you can determine if it is the problem. If you measure 12 to 13 volts, your automobile battery is healthy and the problem lies elsewhere. If the voltage reading is less than 12, the problem will probably be resolved by replacing the battery.

How can you use a key fob to start a 2021 Nissan Sentra?
The automobile must first be in park and all of the doors secured. Don’t worry if the doors aren’t locked right now. Just carry out these actions.
- Make certain that your Nissan is visible.
- If the doors are locked or unlocked, hit the lock button on the key fob.
- Press and hold the remote start button for at least 2 seconds within the next 5 seconds.
- The engine of your Nissan vehicle will start, along with the automated temperature control system turning on.
- If no extension is made, the engine will shut down on its own after 10 minutes.
Remote Start Extension
Every new Nissan vehicle equipped with remote start has the option to prolong its duration once for an additional 10 minutes before shutting off. Repetition of steps 2 and 3 from the preceding list results in the extension. When you complete the extension, the extra 10 minutes begin. For instance, if the extension is activated eight minutes into the initial remote start, it will continue to operate for a further ten minutes, giving it a total duration of 18 minutes. Your Nissan’s ignition switch must be turned on and off after using an extension for remote start to function once more. Additionally, this occurs automatically because using the ignition is required to start the vehicle.
Why won’t my automobile crank over?
A fading or dead battery, frayed or corroded connecting cables, a defective alternator, or a problem with the starter are the common culprits when a vehicle won’t start. It can be challenging to tell whether a battery or alternator issue is at hand. Here’s how to determine who the culprit is.
Bad Battery Symptoms
Consider a failing battery, a loose or corroded connection, or an electrical draw if your car cranks slowly, starts inconsistently, is harder to start on chilly mornings, or doesn’t make any sound or light up the interior when you try to start it. A low battery with terminal corrosion that is obvious is likely damaged.
If a jumpstart is successful, a battery issue is present. However, you must also determine whether it is just nearing the end of its life or whether there are more serious problems. A malfunctioning alternator may be the cause of a dead or depleted battery. The additional pull from auxiliary lights, fuses, sound systems, alarms, and other devices may also be the cause.
Is it possible to push-start an automobile without a key?
We regret learning that your handbag was taken. With a push-button ignition and no replacement key, you will need to utilize a smartphone app or contact a locksmith to start the car.
Try a handful of these techniques if you want to start the automobile without the key:
- Start the car’s engine with the mobile app.
- Ask a dealer what the best cure is by getting in touch with them.
- Just as you would if you had locked your keys in your car, dial a locksmith.
- Replace the electronic control unit (ECU), which, if it detects that someone is attempting to steal your car, disables certain parts of it. But this can cost $1,000 or more, so it’s a pricey repair.
Always keep a spare key or key fob in a protected location in the future. You might also want to think about getting roadside assistance from Jerry or adding towing and labor coverage as an addition to your auto insurance policy.
