Self-Programming
In the years leading up to the 21st Century the technology for car keys evolved from mechanical keys and became an amalgamation of electronic and physical protocols to stop theft. The new keys are fitted with a microchip which must be programmed in order to connect to the electronic system of the vehicle. Professional locksmiths equipped with the required equipment can reprogram your keys. Many cars, particularly luxury cars, require that only the dealer be able to create new keys.
The procedure to do this yourself varies from manufacturer to manufacturer. In general, you'll need to put the spare key in the ignition and manipulate it (according to the instructions in the owner's manual) until the car enters programming mode. It will only last a few moments before the car is out of programming mode.
When your car is in programming mode, you'll have to repeat the procedure for each key you'd like to program. The instructions in your owner's manual should be specific to the type of key and model you're trying to program, as some models have additional security features that have to be turned on (for instance the passcode required to access certain programming modes).
Certain models also require a specific code that you can only get through the dealer for a cost. This code protects you from "skimming" which is when a thief attempts to read your key's information through the OBD2 port in order to start the car and then steal it.
It's a great method for you to save money, however when the key isn't programmed correctly, it won't function to unlock or start your vehicle. A trusted auto repair shop like J.C.

This requires reprogramming the new key's transponder to match the settings of the car that was originally programmed.
Some cars allow you to do it yourself, but most require a professional dealer to use a tool that can connect to the vehicle and read the programming data from the ECU. The key is then reprogrammed in order that it matches the car's specifications and you can use it as a normal key.
There are a variety of car key programmers. Some use specific brands and models of vehicles some are more universal and can be used on a wide variety of automobiles. Most of these tools feature an LCD display with a few buttons to enter programming modes. Then, you can plug the device into the OBD-II port to begin reading and programming the new key.
It takes only a few minutes for professionals to program a new key for the majority of vehicles, however some cars require longer and more complex procedures to reprogram keys correctly.

Key Fobs
Modern key fobs offer a number of convenience and security benefits. They can replace or enhance traditional car keys and manage more than just locking doors; they can start the engine, trigger the alarm, and perform other functions.
The key fob utilizes radio signals to communicate with a receiver in the vehicle. When you press a button on the key fob, it sends an appropriate code to the receiver, which responds by performing the function you want. Commercial building owners also make use of key fobs because they can connect them to an overall system of access control. This allows them to track who is entering and leaving and also prevent fobs from being stolen or lost.
As with any other electronic device keys can fail periodically. Since they are constantly tossed around in pockets and purses, they can become damaged or lose their signal. And although they are built to endure some punishment, they're not impervious to damage; after all, they're nothing more than plastic and metal.
If your key fobs aren't working, you may need to replace the battery. Make sure to use the correct battery and consult your owner's manual to learn how to replace it correctly. Also, ensure that you follow any additional steps for reprogramming or recalibration that might apply.
Another common cause of failed fobs is simply wear and wear and tear. They may break or wear out when dropped, smashed against objects, and jostled around in purses and pockets. Often, a quick and inexpensive fix is all that's needed to get your key fobs back running.

Keyless Entry
Keyless entry allows you to unlock and start your car without having to insert a physical key. It utilizes a radio signal to communicate with your car's internal system. You can also control other features, like the climate controls or music system.
Modern keyless entry systems employ rolling code technology to guard against security breaches. It's important to note that even this technology is not completely secure. Utilizing a technique known as "replay attack," a thief can use the key fob's transmitter to transmit a message which is recorded by the vehicle's receiver. Once the message has been recorded, a rogue device can retransmit this transmission to the vehicle's receiver and gain access.
Based on the make and model of your car, you might be able to program new keys yourself, or employ an automotive locksmith to do it. Certain car manufacturers offer an onboard program specifically designed for them and others require you have a sophisticated programmer attached to the OBD2 connector.
The most common way to program new car keys is to place the key fob in the ignition and then turning it on repeatedly in a certain sequence. When the car is placed in "programming mode," one or more buttons on the fob are pressed to send the digital identification code to the computer. The computer saves the code and removes the car from the programming mode.
Certain manufacturers require you to have an advanced computer to program key fobs, and some of these are expensive and difficult to use for the average person. It is recommended to delegate the work to an automotive locksmith or dealer.
To begin programming the keyless entry system begin by stepping into your vehicle from the driver's side and close all the doors, with the exception of the driver's. programming car key will prevent the system from locking your doors while you attempt to program the key. Then, with the ignition key and the rest of the keys you want to program close by, press and hold the button on the fob that you wish to activate until the warning lights flash twice.
