4 Commonly Asked Smart Key Questions, Poplar Tent, North Carolina

Newer vehicles come equipped with keyless remotes known as smart keys. They enlist radio frequency and infrared antennas to communicate with the vehicle whenever the two are in close proximity to one another. If you’ve recently purchased a car that uses one of these keys, it’s only natural to have some questions. Here are some common queries new users regularly want answered.

FAQ About Smart Keys

Why won’t my engine crank when I have the smart key and press the “start” button?

The most common reason for this problem is forgetting to firmly press the brake pedal before pressing the start button. However, if you’ve had the vehicle for a while, it could be that your smart key battery is weak. In some instances, drivers accidentally deactivate the smart key, but there should be a switch nearby you can turn on to solve this problem. Check your owner’s manual for the precise location.

How do I unlock my car and start the engine if the smart key battery dies?

In most instances, a traditional car key should be found inside the smart key case. There should be an easy way to open it like pushing a button on the bottom of the fob. The metal key will allow you to unlock the doors, but when starting your engine, press the brake like normal and hold the fob near the start button as you press it.

What should I do if I lose my keys?

smart keyYour smart key is uniquely tied to your vehicle, so if it goes missing, you’ll need to have the car reprogrammed. You’ll also have to contact the dealership for a key replacement. The new key will then be paired with the vehicle and overwrite the connection with the original one.

How close does the smart key have to be to the vehicle in order to work?

This can vary from one manufacturer to the next. In recent years, many models have decreased the distance to increase security. Still, one vehicle might unlock your car from nine feet away, while another requires you to be within five inches. In some instances, it’s also possible to reprogram these settings to a distance you are more comfortable with.
