How Does a Remote Key Work and What Happens if You Lose It?

You probably use your remote key quite a bit. It unlocks your car and starts the ignition. However, a lost key to your vehicle can be a problem.

Most people don’t think much about this until they lose their remote. How does it work in the first place, and what’s involved with getting a new one?

Keep on reading because this article will teach you everything you need to know!

How Does a Remote Key Work?

A remote key, also known as a key fob, is a small, hand-held electronic device used to unlock and lock a vehicle. It usually attaches to a keychain and has a button that, when pressed, will unlock or lock the door. 

A remote key fob is a keyless entry device that uses radio waves to unlock a car door without using a key. The key fob transmits a signal to a receiver in the car door, unlocking the door. It may also have additional buttons that can be used to activate the vehicle’s alarm system or to start the engine remotely.

It consists of two main parts: a physical key (also called a transponder key) and a remote. The physical key part of the remote key is used to start the car. The remote part is used to lock and unlock the doors and trunk.

What Happens if You Lose It? 

If you lose your remote key, you can usually purchase a replacement from the dealership where you bought your vehicle. You can still start the car with the physical key if you need to start the engine. But if you lose both of your keys, you will need to have your vehicle towed.

You will also be unable to lock or unlock the doors or trunk. To get a new car key, you will need to contact a dealer or locksmith for a car key repair. The key fob may also need to be programmed to work with your car.

How to Prevent Losing It?

To prevent losing your keys, keep them in a safe place, have a duplicate, and never leave them in your car. You can also consider getting a keychain with a built-in tracker, so you can always find your keys if they go missing.

If you’re worried about losing your remote key, you can purchase a key ring holder or key chain to keep it with you at all times.

Be Prepared and Be Careful Not to Lose Your Car Key

You can usually order a replacement from the dealership if you lose your remote key. However, you may need to reprogram the system if you have a keyless entry system. Either way, it’s essential to be prepared and have a spare key on hand in case of emergencies.
