Car Key Signal Jammer 315/433/868MHz | Portable Anti-Theft RF Blocker Vodasafe
Vodasafe Car Key Signal Jammer 315/433/868MHz is a portable RF signal blocking device designed to interfere with common car key fob frequencies. It is widely used in controlled environments where wireless signal suppression or testing is required.
Modern vehicles often rely on wireless keyless entry systems operating on RF frequencies such as 315MHz, 433MHz, and 868MHz. In certain testing or security simulation scenarios, controlled signal interference tools are required to evaluate signal stability and system response.
This portable device provides a compact and efficient solution for RF signal control applications.
How It Works
This device works by generating controlled radio frequency interference within specific bands used by car key fobs.
When activated, it creates a localized RF noise field that disrupts communication between:
- Car key fobs
- Vehicle receivers
- Garage remote control systems
Supported frequency bands:
The interference is limited to RF communication channels and does not physically damage electronic devices.

FeaturesHigh Power & Wide Jamming CoverageWith a total power of 30W and 4 dedicated antennas, the device achieves a jamming radius of 100-500 meters, capable of covering large areas such as open parking lots or vehicle depots, effectively preventing unauthorized signal access to car remote systems.Flexible Frequency CustomizationUnlike fixed-frequency jammers, the RC30 allows users to mix and match frequencies across its 4 bands. This means it can be adapted to block not just car remotes, but also GPS tracking signals, 4G communications, satellite phone signals, and more-making it a versatile tool for multiple private security scenarios.Portable & Durable DesignWeighing only 1.2kg and featuring a compact size (145×95×45mm), the jammer is easy to carry in the included holster. Its robust build ensures durability, even in outdoor or semi-harsh environments.Reliable Battery & Global Power CompatibilityThe 7.4V 8000mAh polymer lithium battery provides up to 40 minutes of continuous operation, while the 100-240V AC charger supports use in almost any country or region, eliminating concerns about power grid compatibility.User-Friendly OperationThe device is designed for simple operation-once powered on (with antennas connected, per safety instructions), it immediately starts jamming targeted frequencies. No complex programming or technical expertise is required.
