Yes, just because you add security doesn’t necessarily mean the battery will become easier to drain right away.
However, security systems are also electrical components, so their power consumption is not zero. How much of an impact they have depends on the vehicle’s original condition and how it’s used.

In recent years, more and more vehicles have high standby (parasitic) power even in factory condition. As a result, there are cases where the battery is prone to weakening even without any aftermarket parts installed.
So, if you drive the car with the same mindset as you did with older vehicles, the battery may end up taking more of a load than you’d expect.

At Log On, when installing the security system, we don’t just mount it—we also check for electrical changes on the vehicle side and whether any errors are present, and we proceed with the installation in a way that minimizes additional load as much as possible.
If the wiring connections or installation method are not appropriate, the vehicle may not enter sleep mode correctly, which can cause it to consume unnecessary power. For that reason, we pay special attention to this aspect.

Also, the more functions and options you add, the more items you may want to confirm from the standpoint of power consumption.
Depending on your usage environment, it may be reassuring to consider battery-drain prevention measures as well.

That’s why at Log On, we confirm your usage and parking environment before installation, and we clearly explain the key points to watch for even after the installation.
We can propose solutions tailored to your vehicle model and how you use it, so if you have any concerns, please feel free to consult us.

Please also note that a flat battery always has a cause. When a security system is fitted, it tends to be blamed, but how often the car is driven, where the key fob (authentication remote) is kept and the size of the battery also play a part. For example, if the car is not driven for two weeks, the battery drops to around half, and cars with a smaller battery go flat more easily. For everyday tips, see “I won’t be driving my car for a while. How can I prevent the battery from going flat?”.
