If your car comes to life without requiring a key in the ignition but just pressing the Start button, you own a smart key. Proximity keys work so effortlessly that most car owners hardly think about them until the battery fails or it gets lost. So let's look into how it works, what the most typical troubles are, and how a replacement is done.
A smart key or proximity key sends a signal to your vehicle via a radio link, as soon as the key gets within range, the car recognizes it – the door can be unlocked simply by pressing a switch or pushing start button, there's no need to take out the key and put it back in the lock; that's exactly what makes it such a cool invention, it evolved from earlier transponder key technology.
Your smart key will still have a tiny battery in it and as it drains, your vehicle stops recognizing it correctly, the good news is that manufacturers take that possibility into account and equip cars with backups that help start the engine and unlock doors with a dead battery. There should be a mechanical blade in your fob for opening the door, and a designated spot in the car, where you'll be able to hold the fob and unlock the door or turn on the engine.
Check in your owner's manual how you are supposed to start your car with a drained battery and learn that procedure before it happens. You won't get stuck anywhere.
