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:
- inadequate alternator
- Battery deterioration
- Key fob battery failure
- defective starter motor
- worn-out ignition plugs
- an inadequate or dead battery
- fuel pump malfunction
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.

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.

Push-button start and keyless ignition are two examples of the amazing and incredibly entertaining technology that comes with new cars. What occurs, however, if your keyfob is lost? The response is situation-specific. For instance, whether you lose your keyfob before getting into the car or after, your experience will be very different. Simply put, you won’t be able to start your automobile if you lose the keyfob that activates your push-button start before you try to drive in it. But what happens if you misplace your key fob while you’re on the road? That calls for a totally different response, and we have located a video that does just that.

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.
- 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.
- Just as you would if you had locked your keys in your car, dial a locksmith.
- Ask a dealer what the best cure is by getting in touch with them.

What occurs if the key fob breaks?
This issue has been foreseen by automakers ever since the key fob was created. Nothing will happen if your key fob dies while you’re driving. Simply because the key fob is a locking and starting device only, the automobile will continue to run. The key fob has no influence over the ignition or engine once the automobile is moving.
Even though you’ll need to go to a general store or pharmacy to get the battery, replacing the battery in your key fob simply takes a few minutes if you’re pressed for time.
Why not take the time to renew your auto insurance at the same time as you’re replacing the batteries in your key fob?

Can your car still start if the battery in your key fob dies?
- On your key fob’s back, search for a little sliding button. You can slide the key fob cover off or click a button to do so. To get it to release, you might need to use your fingernail and a little force.
- Use the mechanical key to unlock the door after you get it. If your door doesn’t have a key slot, it’s likely concealed beneath the handle cover. To access the key slot, carefully remove the handle cover by using the key.
Now that you’re inside, here’s how to start the car with a dead key fob:
- Check the steering column for a physical key slot if neither of these approaches succeeds (some Mazda models have this feature). To start the car, place the mechanical key within the keyhole.
- Close the key fob after inserting the mechanical key once more.
- Press the START button with the key fob. Instead than pressing the button with your finger as usual, push the key fob against it. Many manufacturers utilize this backup device to make sure the car can start even if the key fob is dead.
- Some vehicles have a secret key fob slot that can be used to start the engine. For instance, the backup slot is located inside the cup holder in some Ford models. Your fob will fit perfectly in the slot. Use the push button start as usual after inserting the dead key fob into the holder.
