The car alarm key fob is necessary to set the car on security, as well as to disable security functions. This is the main purpose of the key fob. But it can also be used to program the alarm functions.
The car alarm key fob is a truly universal thing. Not only arming and disarming is done with a remote control, but also programming of alarm functions is done with it. But for reprogramming functions, it is important to know a few points. One of them is how to enter programming mode. Knowledge of function numbers and their meanings is also required.
Using the key fob in everyday life
Modern alarms usually have three buttons. Moreover, each button can perform several actions. It all depends on the duration of the press. For example, a short press on the button with the closed lock icon locks the car and switches the alarm to the armed mode. A short press on the button with the open lock icon unlocks the doors and disarms the car.
A long press on the door locking button will remotely start the car engine. If you decide to use this function, then get rid of the habit of leaving the car in gear when parked. A long press on the disarming button unlocks the trunk remotely. If you hold down two buttons at the same time, then the search for the car, setting the timer and setting the key fob will be performed. Depends on which alarm model.
We enter the programming mode
First of all, you need instructions for your alarm. In it you will find a list of all the functions that are available. Please be aware that it is not recommended to change some functions, as this may affect the functioning of the vehicle. But to enter the programming mode, you need to find the Valet button. When buying a car in the showroom, the dealer is obliged to provide you with information about where this button is located.
It is necessary for emergency disabling of the security system and for entering the programming mode. Now look at what kind of LED you have showing the alarm mode. It can be made either as a single LED or as a matrix of several LEDs. The difference is that when entering the programming mode in the first case, you will need to count how many times the LED has blinked, and in the second case, a number corresponding to the function number will be displayed on the matrix.
In any alarm, the transition to the programming mode is carried out by turning the ignition on and off, followed by pressing the Valet button. Using the buttons on the alarm key fob, you can go to the next function, select the current value, exit the programming mode, and save the values.
