Key Fobs

Modern-day key fobs offer numerous advantages in terms of security and convenience. They can replace or enhance traditional car keys and can be used to control more than only locking doors. They can start the engine, trigger the alarm and perform other functions.

The key fob communicates to the receiver in the vehicle via radio signals. When you hit a button on the key fob, it transmits a code to the receiver, which responds by performing the desired function. Key fobs are also a favorite among commercial building owners, who can incorporate them into a larger access control system. This lets them track who is allowed in or out, and block fobs which have been taken or lost.

Like all electronic devices keys can fail from time to time. Because they are constantly tossed around in pockets and purses, they can become damaged or lose their signal. Even though they're designed to withstand some punishment, they're not impervious to damage; after all, they're nothing more than plastic and metal.

Modern keyless entry systems employ rolling code technology to guard against hacking and other security breaches. It's important to note that even this technology is not 100% secure. A burglar could employ a technique referred to as "replay attack" to transmit a message that is recorded by the receiver of the car. After the message has been recorded an intruder device could transmit the same message to the car's receiver and gain access to the property.

Depending on the model and make of your vehicle, you may be capable of programming new keys by yourself or hire an automotive locksmith to complete the task. Certain car manufacturers have an onboard program specifically designed for them and others require you have an advanced programmer connected to the OBD2 connector.

The most common method to program new keys for cars is to insert the fob of the key in the ignition and then turn it on in a particular sequence. When the car is in "programming mode," one or more buttons on the fob are pressed to send the digital identification code to the computer. The computer then stores this code and then takes the car out of programming mode.

Some manufacturers require that you have a special advanced software programer to program key fobs. These are costly and difficult to use by the typical person. This is why it's best to let a professional locksmith or dealer do the job for you.

To set up the keyless entry system, enter your vehicle from the driver's seat and close all the doors, with the exception of the driver's.

After that, with the ignition key and the other keys you wish to program close by, press and hold the button on the fob you want to activate until the warning lights flash twice.
