Nancy explains how a keyless ignition system works with a smart key on newer vehicles
Transcript:
What does having a keyless ignition system mean to you? Well, of convenience, of course. Hi, I’m Nancy at Kneble’s Auto Service Center. This system allows the driver to start the vehicle while having a key fob in your pocket. You just press that start button and you’re ready to drive. “Well, how is this done?” you ask? There are antennas in the car’s frame that recognize the radio signal transmitted by the key fob, which is amplified with a battery in the key fob. Now it can determine with calculations that you are indeed in the vehicle and when you press the start button, the receiver disables the immobilizer, powers the start circuit and you’re ready to go, the engine starts.
But remember, in your key fob, there is a battery, just like the battery in your watch. It can go dead and need to be replaced, but when it does go dead, it will no longer work. Therefore, manufacturers put typically a backup key inside the key fob. Make sure you check with your manufacturer to know where your backup system is.
