Hi there. Most of the time this occurs when the key fob battery gets low. If the battery is replaced then it should be fine. If the battery does not help then there may be a programming issue within the security system and the ignition switch. I usually either try another remote or I replace the battery and test it. If the problem persists then I check the computer programming to make sure that it is properly registering the fob. If not then it may need to be reprogrammed. Some of the time the module needs to be replaced. If you want to have this starting problem checked, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose and repair this.

Here`s how to program your Hyundai`s fob:

Use your key to switch on the ACC function on your vehicle`s ignition. Press the unlock button on your key fob (also sometimes the open button) and hold down for several seconds. A light will flash (usually your car`s hazard lamps) to indicate successful programming.

The most common reasons a Hyundai Elantra key won`t turn are a binding steering column/lock, an ignition switch issue, or a problem with the ignition key.
You can remote start your Hyundai Elantra with the key fob or a Blue Link Remote subscription package.
The ignition switch, located on the steering column or in the dashboard, takes the power from the battery and directs it to all the accessories and electrical components of your car.
Insert your ignition key and turn it to Accessory (or press the start button once without pushing the brake pedal). Press the Lock button on your remote car starter. Within five seconds of turning it on, turn your key back to the “off” position (or press the start button again).

I have a 2013 Hyundai Elantra with keyless entry/start. Lately when I push the ignition button to start my car the horn honks.

If the battery does not help then there may be a programming issue within the security system and the ignition switch. I usually either try another remote or I replace the battery and test it.

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.

So I have a hyundai sonata se push to start. My car won’t turn on, power is working, I push tof start but it won’t crank. I don’t
ANSWER : Hi there. It sounds like you have a failed starter. However, without proper testing there is no way to be 100% sure. I suggest having the battery tested first with a digital battery tester that provides current voltage, cold cranking amps, and state of health. Also inspect for corrosion on the terminals and cables as this will cause excessive resistance and not allow proper voltage/amps to the starter. Other possible failures could be in the wiring harness, relay, fuses, or communication network. I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a car does not start inspection.

I changed the battery in my ford explorer 2013 and the lights and radio work but it won’t start. It says to push the brake but it won’t work.
ANSWER : Hi there. Check to see if the battery cables are tight. If the cables are tight, then check the brake switch on the brake pedal. It may not be responding to the computer as it could be damaged or shorted. Check the fuse box for any blown fuses and see if there is any burnt wires leading up to the brake switch. The computer has detected that the brake switch is not working and when you step on the brake pedal to start the engine, the message on the dash should go away but its not. If you need further assistance with getting your engine to start, then seek out a professional, such as one from Your Mechanic, to help you.

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 won’t start. It has a push button start. The car makes an attempt to crank, but struggles with turning over
ANSWER : Hello, thank you for writing in. If the starter is not turning over the engine fast enough, the engine will not start. Due to you symptom of the vehicle cranking slowly or poorly, chances are the starter is failing to spin the engine fast enough for the it to start its combustion cycles. You will want to turn your attention to the starter and its circuit. Your husband should check the available voltage at the starter to see if it is receiving enough power to properly do its job. If it is, then the starter has failed to use the power. If there is less than 10 volts, there is something that is causing the vehicle to lose electrical power. For more help resolving the starting issue, contact our service department to schedule an appointment.

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.

My car will be starting perfect and when the gas tank gets lower it will start having problems .
ANSWER : Based on the information you gave, it sounds like a possible fuel starvation issue, caused by a partially blocked, in-tank fuel filter or a crack in the fuel pump housing. The remedy would be to replace the fuel pump assembly and filter. The overheating may be caused by several things, including a stuck thermostat, faulty water pump, or even a cracked head gasket. I suggest having a certified technician, like one from YourMechanic, inspect the relevant systems to pinpoint the cause of your vehicle’s hard starting issue and overheating problem.
