Your battery should be checked first because starting the car consumes a lot more energy than running the radio and lights. If your battery is original, it could be time for a replacement.
I don’t believe anyone has conclusively identified an intermittent issue that prevents some cars from starting, where the car has electricity but won’t start when the key is turned. Most people can ultimately get it to turn over after several tries, however other people claim that you can also get it to turn over by simply holding the key in the start position for a sufficient amount of time (20–30 seconds). Throughout a few weeks last summer, my 330 performed this a few times. Prior to that, I would frequently have a 1-second or less delay when turning the key. The good(?) news for me was that it simply stopped occuring after a few weeks; at the time, I was considering purchasing a beginning. It hasn’t done so since. In my search to discover what the heck was wrong, I discovered reports that were identical. There has been a lot of speculation regarding the starter, battery, and key sensor in the column (my was brand new). Consequently, if your battery is in good condition, you might try holding the start key down for a considerable amount of time; if it eventually turns over, add your name to the list.
Which Causes are Most Common?
Your BMW won’t start for a multitude of factors. The most common reasons your BMW won’t start normally include a dead key fob battery, a dead 12-volt battery, corrosion on the battery terminals, a broken alternator, a clogged filtration system, a damaged starter, an overheated fuse, an empty petrol tank, an ignition coil error, or any electrical issue.
causes of the BMW 530i not starting and solutions
Although the BMW 530i is a dependable travel companion, it is a machine with hundreds of interrelated parts, and like all machines, it occasionally fails to perform as intended. We discuss the most frequent 530i breakdown causes in this article, along with solutions.
The most frequent causes that prevent your BMW 530i from starting normally include a dead key fob battery, a dead 12 volt battery, corrosion on the battery terminals, a bad alternator, a clogged fuel filter, a broken starter, a blown fuse, an empty gas tank, an immobilizer error, or any electrical system fault.
Why won’t my BMW start despite clicking?
When trying to start your car, a loud clicking sound may indicate an issue with the electrical system. It’s possible that your battery is dead or that the alternator, which charges the battery, is malfunctioning.
The starter, a small motor powered by the battery that starts the engine, is unable to maintain power if the clicking noise is electrical in origin. Instead, it makes a clicking sound and switches on and off quickly.
Remember that in situations like this, a misfiring starter is really a symptom and not the root of the problem. Your automobile’s electrical system is probably to blame, which is why a jumpstart could briefly move your car.
Once it’s operating, have an experienced technician inspect the entire electrical system. Your alternator or battery might need to be replaced. Alternately, the issue might be resolved by simply cleaning the battery terminals of corrosion to improve the battery’s connection.
You’re not the only one having issues with your automobile battery. According to AAA, among the top three reasons members call for roadside assistance are battery issues, with the majority of those calls occurring in the summer.

How can you figure out why a car won’t start?
With a hard item, try lightly tapping the starter a few times, being careful not to pound it. Since you’ll be tapping the electrical components back into contact with one another, in certain situations, this gently tapping can assist in helping it power back up. You know how on older TVs the picture can occasionally be brought back into focus by banging on the side? Kind of in that way. But much like your malfunctioning television, your car might only respond to this fix momentarily, lasting only long enough for you to reach the next servicing facility.
How come my auto decided to suddenly not start?
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 distinguish between a battery or alternator issue.
What occurs if the battery in the BMW key runs out?
You won’t be able to use keyless entry or remote unlocking if your BMW has Comfort Access if the battery in your key fob has died. You can still enter and manually start your automobile, though.
Press and hold the key release button at the remote fob’s base while unlocking the door of your car, then slide out the internal key blade. This can be used in place of a standard key to unlock your car. You can locate a little hole on the bottom of the handle if the keyhole is hidden on your car door. Use the key blade to pry off the trim panel and expose the keyhole by inserting it into the hole.
Once you’re inside, put your remote key fob in the ignition slot or, if your car doesn’t have one, press it up against the steering column’s key markings. If your key fob dies, you will still be able to start your BMW using the start/stop button on the dashboard.
Why do the radio and lights work in my car but not the engine?
When trying to start a car, most people assume that the battery is still good if the radio comes on. Although technically valid, this does not imply that the battery is in good condition. It might surprise you to learn that just because your radio still functions, your battery is still not the problem.
The radio and lights may be turned on with very little power, so the fact that they turn on when you try to start the car is not the huge diagnostic clue that we have a tendency to think it is. While the battery may still have enough power to start the radio, the other electrical systems may not be able to. It may be difficult to pinpoint the root cause of your car’s problems because some components may be powered by a dead or leaking battery.
You might also have filthy or corroded battery terminals if the lights and/or radio turn on but the car won’t start. The electrical system and batteries are joined by the terminals.
The connection can be harmed if these are filthy or rusted. Even though the battery has plenty of life left in it, a bad connection can prohibit it from providing power effectively. If the terminals are corroded or unclean, it is pretty simple to detect this. If they are, you can rather easily clean them yourself.
A failed attempt to jump start your car can also confirm or rule out the battery as the problem. It’s likely that your battery was the issue if you can start the car by jumping it. This isn’t always the case, though.
My car won’t start, but the battery is fine. Why?
Your starter may be the issue if the battery appears to be in good condition. A starter is a little motor that uses battery power to pull current in order to start an engine. When you turn the key in the ignition, you can hear a clicking sound if the starter fails or malfunctions. In some cases, loose connections are the issue, while in others, a new starter may be required. There is no assurance that jumping a car will fix starter issues.
Why won’t my car start even if I have power?
Damaged or Broken Ignition If your headlights work but your car won’t start, your battery is charged but the starter or ignition isn’t working properly. A starting engine can be jumped using a charged battery if the starter or ignition is the issue.
When I try to start my automobile, there is only one click?
A single, loud click coming from the beginning relay or starter solenoid may indicate a problem with the starter motor. This typically indicates a malfunctioning solenoid, relay, or bad or jammed starter motor.
Solution: To start the engine again, rock your automobile back and forth or tap the starter motor with a hammer. If it functions, you are ready to go! However, if this keeps happening, your starter motor is probably broken, and you’ll need to replace it. Here, a battery voltage check will also be useful.
Before you go to buy a new starter motor if you feel the existing one is defective, perform these checks.
When you try to start your car, all you hear is a single click.
A dead battery is arguably the most frequent issue that results in a clicking sound when attempting to start an automobile. You may easily test the battery by measuring its voltage using a voltmeter (or multimeter).
A automobile battery should typically have a voltage of 12.6 volts or higher. The battery is probably at blame if the test reveals that it is lower.
By jump-starting the vehicle and continuing to drive to replenish the battery, you can still start it. This, however, is not a permanent fix.
What does it imply if your car won’t start and your brake pedal is stiff?
The majority of contemporary automobiles include power assist, which depends on a brake vacuum to function. If you’ve been applying pressure to the brakes while the engine is off, you may have exhausted the reserve vacuum in the vehicle. As a result, your brake pedal will become stiff.
Will a dead key fob prevent a car from starting?
Yes, a key fob with short battery life may prevent your automobile from starting. The key fob for your automobile is an electrical gadget with a battery inside that powers signals sent from the key fob to your car. Your car’s computerized systems get alerts in accordance with the key fob commands you press, and the vehicle subsequently reacts as necessary.
This function depends on the battery in your car’s key fob; if it runs out, you might not be able to start your car without a jumpstart. Your ability to start your car may be affected if the battery in your Honda keyless remote is low.
It just clicks when I try to jump start my car.
The battery is typically to blame for that annoying clicking sound, and the solution may be as easy as a jump start or cable tightening. But a single click suggests that the starter motor is at blame.
Why doesn’t my automobile recognize my key?
The key fob won’t be recognized by your car because the remote’s battery is dead. The actual remote is damaged or is no longer programmed to your vehicle. Low automobile battery voltage. The keyless entry system is broken.
How can I tell if the battery on my car key is running low?
When the battery in the fob gets weaker, the transmitter’s range decreases. Your range is deteriorating if you find that you need to be much closer to your automobile than usual. This serves as a reminder to replace your battery. Other signs comprise:
- If your key doesn’t signal at all
- If you have to click the button several times before your car responds
- If your key remote behaves erratically or inconsistently
