Push To Start Cars

ShareTweetPin For the vast majority of people, cranking your car involves getting the key out, sliding it into the ignition, and turning it to the “run” position. However, if you have a push-button start system, then you don’t have to do that. You just get inside and push the button labeled start/stop, and the engine roars to life. Simple and easy, right? Actually, these are pretty complicated systems. The purpose of a push-button start system You might think that the primary purpose of a push-button start system is convenience, but you’d only be partially correct. They’re really designed to discourage theft. Because there is no physical key necessary to crank the car, it actually makes it harder for would-be thieves to make off with your vehicle. Though you don't need a traditional key to get the car started, you need a special fob. It can stay in your pocket, where it broadcasts a signal to the car’s computer. The computer recognizes the fob’s code, and lets you crank the ignition. Of course, there are some safeguards in place. For instance, you can’t start the engine if you’re not holding the brake and have the car in park. If either of these conditions isn’t met, the engine won’t start. Another safeguard here is that the car’s computer is only able to recognize the code from your specific key fob. This means that another driver with their car's fob won’t be able to get in and start your engine. How a push-button start works The only real difference between a push-button start system and a conventional keyed ignition is that you don’t need a key to close the circuit on the ignition. The button does that. Pushing the button does the same thing that turning the key does. The fob is really the beauty behind the system, which ensures that only you can start the car. Potential problems There are a few issues with push-button start systems, though. For instance, the fob can be removed from inside the car during operation and it will not affect operation. The engine will keep right on running until the car runs out of gas. Another potential issue is the fact that the car can be shut off while still in drive, which means that it may roll accidentally if you were to get out of the car without applying the parking brake. electronic ignition system key fob keyless entry keys ignition system ShareTweetPin The statements expressed above are only for informational purposes and should be independently verified.

Does push button start make it easier for someone to steal my vehicle? Push button start provides superior car theft protection compared with keyed ignition. What do I do if I just want to turn on my radio? Push button start is designed to work similarly to using a traditional key ignition; you can turn on specific features by quickly pressing your push button start without holding it and without your foot on the brake. Check your owner’s manual for information on how many pushes activate which features of the car. One can think of push button start like this. With each press of the button, it’s like turning an ignition key one position at a time. With the foot off the brake, one touch turns on the radio.  Another touch turns on the dash and other accessories. Push it again and everything turns off.

In a striking example of the law of unintended consequences, a popular automotive convenience feature, push-button start, can lead to accidental death from carbon-monoxide poisoning. A simple technical fix—an attention-grabbing warning audible from outside the car—could head off the problem before it happens. In cars that have keyless, push-button ignition, an electronic key fob is recognized by the car to authorize driving and the use of power accessories. That fob can conveniently remain in the driver’s pocket or purse, as the ignition switch itself is just a button on the dash. Danger can arise, though, if a driver inadvertently leaves the car running when exiting the vehicle—an easy thing to do intentionally or accidentally. Even if you take the key fob with you, the engine can keep idling. If the car is parked in a closed garage attached to a house, especially a basement-level garage, carbon monoxide fumes from the idling engine may seep into the living area, possibly harming anyone in the house. 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. A driver doesn’t have to be absent-minded to assume that the car is shut down—after all, the engine isn’t running. But the car may not be truly off. The engine could restart itself, say to address a climate control need, potentially sending carbon monoxide into the residence. News reports have linked more than a dozen carbon-monoxide deaths to keyless ignitions, and a number of lawsuits have been filed against automakers including a potential class action suit against the 10 largest automakers, filed in late August. That suit, brought in California, alleges that automakers have known about this issue for years but ignored it. However, many vehicles already try to warn someone that they’ve left the car running. They sound either an external chime or a chirp of the horn, if drivers leave the engine idling and walk away with the electronic fob. A quick scan of our current test-car fleet turned up both kinds of signals, chimes and horn chirps, and some cars that remain quiet. This isn’t a comprehensive look at every vehicle with push-button start, just observations of vehicles we are currently driving.
