In the years leading up to the 21st century, car key technology started to move away from traditional mechanical keys to a hybrid of electronic and physical protocols to prevent theft.

It will only last only a few minutes before the car exits the programming mode.
Once your car is in programming mode, you'll have to repeat the procedure for each key that you wish to program.

Most of these tools feature a small display and several buttons to switch between programming modes. Then, plug the device into an OBD-II connector to start reading and program the new key.

Key Fobs
Modern day key fobs provide a host of advantages in terms of security and convenience. They can replace or complement traditional car keys and do more than just lock doors. They can also start engines, activate alarms, and perform many other functions.
The key fob communicates with the receiver in the vehicle using radio signals. When you press the button on the keyfob, it sends the code to the receiver which then fulfills the function you desire. Commercial building owners also use key fobs to integrate them into an overall system of access control. This lets them keep track of who enters and exits and can stop fobs that were lost or stolen.
Like all electronic devices, key fobs can fail at times. They may be damaged or lose their signal when they are lost in purses or pockets. Even though they're designed to withstand a lot, they are not impervious to damage; after all, they're no more than plastic and metal.
If your key fob stops functioning, it could be time to replace the battery. Make sure you use the correct battery and refer to the owner's manual to find out how to replace it correctly. Be sure to follow any additional steps that may be required for reprogramming and recalibration.
Another common reason for failing fobs is simple wear and tear. As they are continually dropped, bumped into things, and jostled about in purses and pockets they may wear down or even damaged. A simple and cheap fix can often be all that's needed to restore your keyfobs to working order.

Keyless Entry

Modern keyless entry systems use rolling code technology to protect against hacking and other security breaches. It's important to note that even this technology isn't 100% secure. A thief could use the technique known as "replay attack" to send a message which is recorded by the receiver of the car. Once the message is recorded, a rogue device can send the same message again to the car's receiver and gain access to the secured property.
Depending on the make and model of your car, you might be able to program new keys by yourself or hire an automotive locksmith to do it. Certain car manufacturers offer a special onboard programming process, while others require you to have an advanced programer connected to the OBD2 port.
The most commonly used method to program new keys for cars is to put the fob of the key in the ignition and then turn it on in a certain order. This puts the car in a "programming mode," and once it is activated, one or more fob buttons are pressed to transmit the digital identity code to the car's computer. The computer saves the code and takes the car from the programming mode.
Certain manufacturers require that you have a special programmer to program key fobs. These are expensive and hard to use by the typical person. It is best to leave the work to an automotive locksmith or dealer.
To start programming the keyless entry system start by entering your car from the driver's seat. Then close all doors, except the driver's. This will stop the system from locking your doors while you attempt to program the key. Then, with the ignition key along with the other keys you wish to program close by, press and hold the button on the fob that you wish to activate until the danger lights flash twice.
