Can changing your Battery cause your car not to Start? Alarm Reset

Tired of that annoying beeping sound?

We dont blame you! Well help you troubleshoot this frustrating problem.

The first thing youll want to do is go to your alarm keypad. If you know the code to disarm the alarm, enter it and see if that stops the beeping sound. If you dont know the code, look for buttons labeled clear or reset and press those.

Note: You can also try pressing the * or # keys, as these buttons often silence the keypad sounder. However, DO NOT press those keys simultaneously because on many systems that combination is used as an emergency signal to dispatch police.

If the beeping sound persists or starts again shortly after you put in your code, you may have one of the following issues:

  • Loss of power
  • Low or dead backup battery
  • Phone line connection issue

Lets look at how to troubleshoot each of those problems below.

    Viper Alarm And Its Features

    Before we proceed with resetting a Viper alarm after changing the battery, it is important to first understand what this type of alarm does.

    Viper alarms are known as one of the best brands in home security systems because of their outstanding features that set them apart from other types of alarms, such as:

    2. The Viper system is a two-part security device that includes an alarm and keyless entry remote.

    3. Viper alarms have been installed in homes, businesses, and vehicles for decades.

    4. A home with a viper alarm has increased safety while its occupants sleep or work inside.

    Electrical Issues After Replacing The Battery

    Late model vehicles have many computerized systems in most cases, each system is under the basic control of its own computer . There can be more than twenty modules on each vehicle and many of these modules have some sort of “learned” memory, which may be lost when the battery is disconnected. This can cause something minor, like the clock to lose its time, but it can also lead to engine stalling or even a failed smog inspection.

    In order to avoid this issue, it has become more and more critical that power is supplied to the electrical system while the battery is disconnected, for any reason, including replacement. Luckily, there are many “memory saving” devices available that can be connected to the cigarette lighter or the OBDII diagnostic connector. These devices will supply enough power to the modules while the battery is disconnected so they don’t lose their memory.

    Be sure to follow all manufacturer directions if you use any of these “memory saving” devices. Most of these devices use a small battery to supply power. Opening a door or turning the ignition on with the main battery disconnected can cause the battery in the device to lose power as well.
