This process is similar to how you would program a new remote control to work with your television. This is because modern cars have transponder chips inside the key that communicate with the car's computer system to turn the vehicle on and off, lock or unlock doors and more. Keys can include buttons that allow you to open or close doors, activate alarms, and more, depending on the model and make of your vehicle.

They can make an original key and program it into your vehicle so that it can start the car just like the old one did.
A second question that people often ask is if they can reprogram an existing key to work with their vehicle. While it is possible to do this in a few instances however, the majority of manufacturers will only make the key work with a vehicle owned by them. This prevents other people from being in a position to steal your vehicle through reprogramming an empty key to work.

Key Fobs
Key fobs allow you to combine multiple functions into one portable package. With the touch of one button, or proximity scan, vehicle owners can control the door locks, ignition systems, and a lot more. This eliminates the requirement for physical keys that are traditional and can reduce costs associated with replacing lost or stolen keys to cars. Fobs are also used to establish controlled access to industrial and commercial facilities. By connecting their backends to a central computer, facility administrators are able to program RFID readers and set access levels for employees, guests or customers.

With inexpensive hardware, it's possible for some bad actors to penetrate a vehicle's system and steal the vehicle. Fobs have security features that are built-in to guard against such attacks. They transmit passcodes which change every time the fob activates and expires automatically after a specific time.
Fobs are also designed to be safe from wireless hacking. The majority of modern key fobs utilize advanced encryption protocols to stop hackers from stealing code transmissions. Additionally, they usually employ an RFID reader with a unique ID that prevents multiple fobs from gaining access to the same area at the same time.
Before you attempt to reprogram your key fobs, consult your owner's manual to find specific instructions for your vehicle. The process for reprogramming is the same for all major car models, however small details may differ. In some cases the locksmith might be required to assist you.
The first step is to take the old fob from your vehicle and safely store it. You'll need to have all your other fobs available. Once you've done this then get in the driver's seat and shut all doors, with the exception of the driver's side door. This is required to activate your car's reprogramming feature.
With programming car key shut off, put your new fob in the window on the driver's side and press the lock button. You should hear a click sound within a couple of seconds. This means that your fob has been successfully changed into a new program. Repeat this process for each of your other fobs.
Transponder Chips
The transponder chip on the top of the plastic component of a modern smart key fob, or remote, is what allows your car to start when you use it. This chip transmits a unique code to the engine immobilizer in the car that allows it to be aware that it's a legitimate key. The chip sends this ID code via radio to the car's computer. If the ID code matches one stored in the car's memory the car's security system will disable the immobilizer, allowing the engine start. When this happens the security light will go off on the dashboard.
If you've got a new car that has a transponder but does not seem to recognize the new key, you can contact a locksmith to cut and program a replacement for you. Make sure you buy the replacement key that's uncut by a reputable company. Secondhand keys are not able to be cut again, and keys that have been cut may not function in your vehicle.

Since 1995, a majority of car makers have improved their systems to prevent thieves from making hot wires to an ignition and then driving away with the vehicle. Even so, thieves can still make off with a vehicle by simply using a laser pointer to "read" the ID code from a stolen or lost smart key, and then start your car's engine. It is essential to keep a spare key to prevent theft.

Fortunately, it's a lot more complicated today. Locksmiths have sophisticated tools and software to reprogram a new key to match the vehicle's current programming.
