Modern alarms are reliable car security and telematics systems with protection against scanning the dialogue code for controlling code grabbers. However, no matter how perfect the protection system is, sooner or later most motorists who use the feedback alarm as the basic protection of the car encounter problems with its operation.

Do not forget that the alarm key fob is a complex device that requires careful handling, as it contains electronics that are sensitive to any external influences. It can easily fail if dropped, accidentally sat on, or simply exposed to moisture. If the screen is damaged, microswitches and LEDs fail, full control of the machine becomes quite difficult, if not impossible.

It happens that the alarm key fob fails at the most inopportune moment - when you need to leave the car in an unfamiliar place or in winter,when it's cold outside and it's impossible to start the car remotely.

Naturally, at the first breakdown of the alarm system, unable to establish the cause, many rush to contact the service center to replace the failed system with a new one. However, there is no need to rush into this.

First, try checking the alarm key fob: you may be able to independently determine the cause of the malfunction and fix it without resorting to the help of professionals. When contacting a service center, you will be charged a rather large amount for this, but you can try to avoid extra costs.

First you need to check the operation of the key fob. Let's say that your car has a Starline alarm. The key fob needs to be inspected and make sure that the device has not been subjected to mechanical stress, and its case has not cracked. If no external damage is visible, you can try to carefully open the device and check for damage to the electronic board. If the diode on your key fob does not glow, it is recommended to check and, if necessary, immediately replace the battery inside it. However, remember that a glowing diode (if any) is not an indication that the battery is working.

If the alarm key fob does not work after changing the battery, it is possible that the cause of the breakdown lies in the wiring problems. Whatever the level of complexity of the alarm system, it has contacts,which tend to oxidize over time, making the operation of the entire system impossible. Therefore, for starters, it is worth checking the performance of the car battery, all contacts and, if necessary, clean them. Sometimes it is enough to remove the terminal from the battery for a minute, and then put it back on again. Also, a low battery is often the cause of alarm failure.

Today on the Russian market you can easily find high-tech car alarm systems from leading manufacturers such as Pandora, Scher-Khan, Starline, offering durable and high-quality devices. But with careless use, even such a reliable device as the Starline alarm key fob can fail.
