Disadvantages Of Push-Button Start In Cars

Push-button start, also known as keyless entry makes it easy for you to start your car without a traditional key. Having purchased a car, you must have been given a way to start it without inserting a key into the ignition slot. This keyless pattern would allow the driver to keep the key fob pocketed when unlocking, locking, and starting the vehicle. 

Therefore, a smart key is identified through one of the car’s antennas in its bodywork and a radio pulse generator in the key housing. Depending on the system, the car automatically unlocks, when a button or sensor on the door trunk is pressed.

 Vehicles with a smart-key system have a mechanical backup. This is usually in the form of a spare key blade supplied with the vehicle.

Consequently, manufacturers around the world, in favor of convenience, are slowly transitioning towards keyless car transponders. BMW and Mercedes-Benz are among the brands making it a standard.

As much as it may be convenient to use, there are some disadvantages of having the push-button start in your car. Also, you could learn a thing or two about how we take such a simple convenience for granted.

Disadvantages Of The Push-Button Start Or Keyless Fob

a. The Cost

Sure, the price of a keyless fob and push-button ignition is included in the price of the vehicle. They get worn out over time and there could be a need for replacement of the entire key fob or to repair the whole system. That can be a pricey purchase just to be able to start your car.

B. Your Car Is Still Running

 Some cars run so quietly, in a crowded or busy street, and there’s a possibility of you leaving the car running as you go to your errand. Yes, some cars will usually shut off as a safety feature. But if your brand doesn’t have this, then your car will keep running until it runs out of gas.

This will be a huge problem when you park your car in a closed garage that’s attached to your house. As there’ll be chances of carbon monoxide entering your house creates a dangerous situation.


c.  Thieves Are Getting Smarter

The keyless systems make it difficult for cars to be stolen. But, with computerized controls, hackers will be developing new ways to try to steal your car. Key programming tools and chips can be found online, and may only be purchased by authorized dealers and mechanics. 

If these tools end up in the wrong hands, they could easily reprogram a blank key fob to your car’s transponder code. They could even hack into the car’s electronic systems to operate the vehicle. 

Are Push-Button Start Cars Safe?

Cars inadvertently left running can lead to carbon monoxide poisoning.  Push-button start can lead to accidental death from carbon monoxide poisoning. There’s a possibility of danger arising if a driver inadvertently leaves the car running when exiting the vehicle.  

A subset of keyless-ignition cars, hybrids, and plug-in hybrids pose an even stealthier problem. Because they are virtually silent when in electric mode, which they may well be when sitting still after parking. An absent-minded driver may assume he turned off the car. But the car may not be truly off and the engine could restart itself.  Potentially, carbon monoxide may be sent into the residence.

News reports have linked more than a dozen carbon-monoxide deaths to keyless ignitions. However, many vehicles already try to warn someone after they’ve left the car running. In other words, push-button start cars may not be quite safe.

Why Are Keyless Cars Dangerous?

One may ask, are all the electronics in my car a good thing? Well, when it comes to safety features such as anti-lock brakes and stability-control systems, the answer is yes. Convenience features like touchscreens, however, could be a distraction and this could be dangerous. It’s difficult to know where to draw the line.

But over time, the keyless-ignition systems pose an overlooked risk. Yes, because sometimes, the driver fails to switch the car off or doesn’t realize it’s still running. It’s a follow-up danger that may occur when you don’t have to physically shut down your car.

Also, keyless ignition is popular and rapidly becoming a standard feature because it’s convenient. The driver can leave the key fob in a pocket or purse and may worry less about leaving the keys in the car. Because it communicates wirelessly with the car’s computer, a keyless system is more secure than an old-fashioned key. Keyless ignition can be less expensive for the automaker to produce due to the fewer moving parts of an ignition tumbler. 

What Do You Do If Your Push Button Start Won’t Work?

If your engine doesn’t crank when you press the start engine button, you may be experiencing one of the following issues.

a. Dead key fob

A keyless entry system won’t start the engine unless it detects that your key fob is inside the car. If your key fob has a dead battery, the system likely won’t be able to recognize when the fob is inside the car. You can get around this issue by placing the fob on the start engine button and pressing down. Although this should allow your engine to start, it’s still worth it to replace the fob battery when you can.

b. Dead car battery

If your fob is working but your engine won’t crank, your car may have a dead battery. To confirm that this is the problem, use a voltmeter to check the battery voltage. If the battery has less than 12.4 volts, it needs more voltage to start the car. You can either hook it up to a charger or jump-start it from another vehicle.

c. Bad starter

A bad starter won’t be able to crank your engine. If you suspect that you have a bad starter, attempt to jump it directly. After doing so, if the starter still won’t crank your engine, you may need to replace the starter.

d. Defective system

When the fob and all your car’s parts seem to be in working order, the push-button start system itself may be at fault. Whether there’s a programming issue or a malfunctioning start engine button, you’ll need a trained technician to diagnose and fix problems with the system.
