Key Fobs

Modern key fobs offer a number of convenience and security benefits. They can replace or complement traditional keys for cars and do more than just lock doors. They can also start the engine as well as activate alarms and perform other functions.

The key fob utilizes radio signals to communicate with a receiver installed in the vehicle. When you press a button on the key fob, it transmits an encoded code to the receiver, which then responds by performing the desired function. Commercial building owners also utilize key fobs as they allow them to integrate them into an entire system of access control. This lets them track who is allowed in or out, and they can block fobs which have been taken or lost.

Based on the make and model of your vehicle, you may be capable of programming new keys yourself, or employ an automotive locksmith to do it. Certain car manufacturers have a special onboard program and others require you have an advanced programer connected to the OBD2 connector.

The most commonly used method of programming new keys for cars is to put the key fob in the ignition and turn it on in a certain order. This puts the car into the "programming mode," and once it is in this mode, one or more fob buttons will be pressed to send the digital identity code to the computer in the car. The computer then saves this code and then takes the car out of programming mode.

Some manufacturers require you to have an advanced programer to program key fobs, and some are expensive and difficult to use by a typical person. For this reason, it's best to let a professional locksmith or dealer do the job for you.
