It is necessary to be quick, as this only lasts only a few seconds before your car is out of the mode.
Once your car is in programming mode, you will need to repeat the process for each key you'd like to program. Your owner's guide should include instructions specific to the model and type of key you'd like to program. Some models have extra security features that must be enabled.

The key fob utilizes radio signals to communicate with a receiver that is installed in the vehicle. When you press a button on the key fob, it transmits an encoded code to the receiver, which in turn responds by performing the desired function. Commercial building owners also use key fobs to connect them to an overall system of access control. They can monitor who enters or leaves and they can block fobs which have been stolen or lost.
