- Strike the battery terminals lightly with a hammer or the heel of your shoe.
- Move the gear lever and try to start the engine, this should be done in the case of a car with a manual transmission.
- Check if there are any visible symptoms of failure in some parts that make up the engine: fuel pump relay.
- Check for leaks in gasoline or oil tanks.
Why does my car key turn but the car won’t start?
It is vital to know the reason that can affect when the car if turning the key in the ignition switch does not start the engine. Let’s see some reasons that lead to the car not starting after turning the key:
weak battery
The car battery has a useful life between 3 to 5 years, then it is necessary to replace this part of the car. It will usually detect when the battery needs to be replaced because it starts to notice faults, among these the engine does not start after turning the key.
Corroded battery terminals
Corrosion on the car battery terminals affects the efficient supply of energy in the various systems of the car, including ignition. This failure is caused when the hydrogen gas released by the battery reacts with the sulfuric acid in the battery. Many car batteries offer durability to reduce the risk of corrosion at their terminals. But, the dangers of corrosion can be more serious than usual when the battery is overcharged or improperly charged.
loose connections
A Bad battery connection can cause the engine not to start after turning the car key. a symptom of loose or loose connections in the car battery, is when the car shakes while driving. Frequent vibrations can loosen the cables, being a reason why the engine does not start when you turn the key.
Faulty fuel pump relay
A Unexpected surge in battery power can cause the fuel pump relay to go bad. The entire system is responsible for transferring and maintaining continuous voltage from the ignition to the engine. In case this part presents problems, when you turn the key in the ignition switch the car does not start.
flooded engine
Exceeding the amount of fuel in the car can prevent air from flowing properly in the engine. This it can cause the ignition to not contact the piston, which would cause an engine problem.
cold engine
Very frosty weather periods negatively affect the engine and ignition of the car. Low outside temperatures can result in engine oil thickening failures, which turns into a lockup and ultimately wears out the battery. If you’re thinking the car won’t start because the battery is cold, don’t keep trying to jump start the car. This can cause the battery to explode, with serious consequences.

Steps to replace car battery
- Choosing the correct car battery, considering several factors when buying the part, before making the decision it is important to consider:
- Technology: Car batteries are generally categorized into two different types of technology: starting and deep-cycle
- Reserve Capacity (RC): The normal amount of time it takes for a car battery to run, should the alternator fail.
- Size: Battery must fit properly in the car’s battery holder
- Cold Cranking Amps (CCA): The battery’s ability to crank in extreme freezing temperatures
Tools needed to change the battery:
Socket wrench, socket extension, wire brush. Now you must comply with the following:
- Put on a part of gloves, loosen the nut of the negative terminal of the battery
- Repeat the previous step with the positive terminal
