Key Fobs
Modern key fobs offer numerous convenience and security advantages. They can replace or enhance traditional keys for cars and control more than simply locking doors. They can start the engine, activate the alarm and perform various other functions.
The key fob communicates to the receiver in the vehicle via radio signals. When you press a button on the key fob, it will send an appropriate code to the receiver, which responds by performing the desired function. Commercial building owners also make use of key fobs to integrate them with an overall system of access control. This allows them monitor who enters and exits, and block fobs which have been taken or lost.
Like all electronic devices, key fobs can fail periodically. They can be damaged or lose their signal if they are jostled in pockets and purses. Although they're built to be able to withstand some punishment, they're not indestructible. After all, they're nothing more than plastic and metal.
If your key fobs don't working, you may have to replace the battery. Make sure you use the correct battery and refer to your owner's guide to find out how to replace it correctly. Also, make sure to follow any additional steps for recalibration or reprogramming that may apply.
Another common cause of failed fobs is simply wear and tear. They may crack or become worn out when they are dropped, bumped into objects and tossed around in purses and pockets. A simple and affordable fix can often be all you need to make your key fobs work again.

Keyless Entry
Keyless entry is a feature that allows you to unlock and start your car without having to insert an actual key. It utilizes a wireless signal to communicate with the car's internal system, and also allows you to control various features in the car, such as climate controls or music systems.
Modern keyless entry systems employ rolling code technology to protect against security breaches. However, it's crucial to keep in mind that even this technology has its weaknesses. By employing a technique dubbed "replay attack" thieves can use the transmitter on the key fob to transmit a message which is recorded by the vehicle's receiver. Once the message is recorded an intruder device could send the same message again to the vehicle's receiver, and gain access to the property.
Depending on the make and model of your vehicle, you might be capable of programming new keys on your own or you may have to employ an automotive locksmith to complete the task. Some car companies have a special onboard programming process and others require an advanced programer connected to the OBD2 port.
The most common way to program new car keys is by putting the fob of the key in the ignition and then turning it on multiple times in a particular sequence. This puts the car in a "programming mode," and once it is, one or more fob buttons will be pressed to send the digital identity code to the car's computer. The computer then saves this code and then takes the car out of programming mode.
Certain manufacturers require you to have an advanced computer to program key fobs and some are costly and difficult to use for the average person. Therefore, it's best to let a professional locksmith or dealer do the work for you.
To start programming for a car with keyless entry begin by stepping into your vehicle from the driver's side and close all doors, except the driver's. This will stop the system from locking your doors while you try to program the key. Press and hold the button on the fob you want to activate while the ignition is on and the other keys you wish to be to program are nearby. The danger light will flash twice.
