When the car is sold the chips in transponder keys will be programmed with a specific code. Some of them use 'rolling codes' which send a different code every time they are used, making it hard for thieves to duplicate them. It is recommended to keep your transponder keys in a secured place if you own a modern vehicle with one.
Transponder keys have a greater lifespan than traditional keys, but they are more expensive to replace if you lose them. If you lose a transponder key you'll need to call the dealership to obtain a new one. You'll need to supply your VIN (a 17-digit number) which will tell the dealer which car it is compatible with.
You'll also need to provide the serial number of the car. This number can be found on a label that's located on the driver's door or on a card in the owner's manual. These numbers are crucial because they can aid in locating your car in the event it is stolen or lost.
Transponder Keys

These keys are great for your car because they deter car theft. Traditionally, car thieves could simply connect two wires together and use them to start your car using a process called hot wiring. When cars started using transponder chips, it became more difficult to steal the car because the thief needed the right key to send a signal to start the vehicle.
If you own traditional car keys and lose it, you can get a new one cut right on the spot by a locksmith in your area. The old key will be deleted from the vehicle's system. On the other hand, if you have an electronic transponder or fob key, you'll need to go to the dealer to have it replaced. This is because the dealer needs to know your VIN (Vehicle Identification Number) to be able to purchase the appropriate key for your particular vehicle.

Fob Keys
The most modern kind of car key has been designed to function like an electronic remote, allowing motorists to open doors and start engines without needing to insert traditional keys into the ignition. These fobs are also known as keys that do not require keyless entry or remote control keys. They are usually cheaper to replace than older, more traditional varieties. However, as with any other piece of consumer technology they're not impervious to damage. They are also easily lost and cease to function as they move around in your pocket or bag.
Fobs emit an electronic code that allows the driver to unlock and start the vehicle. When tapped against a sensor inside the car, it reads that code and causes the doors to open and the engine to start. Certain fobs have additional features, such as an option to summon the car (similar to the Tesla summon feature).
If you have lost your key fob, ensure that your keys aren't locked in a purse or bag that is secured. Then, if they are not in the bag, go through your day and see where you might have lost them. Look in your pockets, in bags that you had in your bag, and on countertops or other surfaces.

Certain keys, like the ones used by Audi and Subaru, require visiting a dealership to get them reprogrammed to your particular key. The good news is that roadside assistance firms like AAA are often able to assist in this regard, too.
If you do decide to purchase a new key fob, comparison shop. Some retailers will cut and program the fob they purchase elsewhere for less money than if they did exactly the same thing at the dealer. Certain key fobs may be replaced with just the outer shell and leave the electronics in good working order. Check your auto club membership or car insurance policy to determine if this is covered.
Chipped Keys
As time has passed, cars have become increasingly technologically advanced. This has led to more sophisticated keys. Unlike traditional keys, which could be duplicated by a locksmith, these newer keys require a specially-designed machine to duplicate. This means that it can be a bit more costly to replace lost car keys if they're equipped with chips in them.

This is because they keep a record of the security information in their system and can pair an updated chip with your vehicle without too much hassle. The process can take a few extra days because the dealer has to order the key directly from the manufacturer.
A professional locksmith can create a duplicate of your transponder key. It is a little more complex than taking your car to a dealer, but you will save money in the end. You'll need your car's VIN number to order an additional copy. You can find this number on your insurance policy or the sticker inside the driver's door jamb.
