How do you use keys to start a car?
When you want to program a second key, the key programming procedure is the easiest to understand. Manufacturers make the process simple and quick because you already have a (master) key that you may use. It should be noted that some manufacturers demand two keys to use this approach, thus in that case, only a third key can be made using it.
- Put your fresh, blank key somewhere convenient to access while you sit in the driver’s seat. Set the second existing key and the blank if you already have two. Keep them nearby in case you need to swiftly swap them out.
- While the key is being programmed, the security light on the dashboard should turn on and stay lit for around three seconds. You might need to confirm on some car models by pressing the buttons on the key. Remove the key, then re-insert it to see if the operation worked after the security light goes out.
- You’re going to need to act rapidly right now. The first key must be taken out and the second key put in within a total of five seconds. This second key can be your new key or a functioning spare depending on your car. Turn the key until the electronics turn on, then turn it off once more. Repeat the method described above.
- Put your working key in the ignition when you’re ready, then turn the key to the “on” position. Don’t actually turn on the engine. Simply turn the key until the electrical system of the vehicle is engaged. Turn the key back to the off position and take it out of the ignition as soon as the power is turned on.
- Repeat this key swapping procedure using a third key if you have one. Leave the backup key in the ignition if necessary. Your car should enter security mode after your new key is inserted and turned off, whichever of the two options you select.
What if the battery in my key fob dies?
This issue has been foreseen by automakers ever since the key fob was created. Nothing will happen if your key fob dies while you’re driving. Simply because the key fob is a locking and starting device only, the automobile will continue to run. The key fob has no influence over the ignition or engine once the automobile is moving.
Even though you’ll need to go to a general store or pharmacy to get the battery, replacing the battery in your key fob simply takes a few minutes if you’re pressed for time.
Why not take the time to renew your auto insurance at the same time as you’re replacing the batteries in your key fob?

THE TECHNOLOGY BEHIND IT
This function only operates while your key fob is active or a short distance away from you thanks to a special signal from a key fob. You can only start your automobile with a push button start using the signal from your key fob.
WHAT YOU NEED TO DO
Applying the brake after getting into the automobile is followed by pressing and holding the engine start/stop button until the engine starts. Make sure your car is in park before pressing the engine start/stop button and holding it down until the engine completely turns off. Consider using the parking brake as well.
TIPS FOR USING
- Apply the parking brake after you’ve shut off your car, like you would with any other vehicle, to lessen the possibility that it could roll away.
- Before exiting your car, make sure the engine is off. This lessens the possibility of carbon monoxide poisoning if you park your automobile in a space with limited ventilation.
