Car Jammers and RF Signal Jammers

Car Jammers and RF Signal Jammers

The current KeylessRepeaterBox category contains three different product scopes: an EAS-system jammer, a standard car-signal jammer and a LONG car-signal jammer. They should not be treated as one universal device. The human live specifications below are retained as category facts and must be checked against the individual product page before ordering.

Standard portable car-signal jammer

The live category states that the portable remote-control and car-alarm jammer blocks 433 MHz, 434 MHz for the VAG group and 868 MHz. It gives an effective blocking radius of 50 m or more and a technical blocking range of up to 50 m.

• 433 MHz ±2 MHz;
• 434 MHz ±2 MHz;
• 868 MHz ±2 MHz;
• rechargeable battery power;
• frequency change within a 4 MHz range, as stated on the live page.

The same human content references 315, 433, 434 and 868 MHz applications and names Teleco and Legrand at 868 MHz, Apollo-C at 433 MHz and security walkie-talkies around 433 MHz.

LONG car-signal jammer

The live category describes the LONG model for 315, 433, 434 MHz (VAG) and 868 MHz. It states that the device works in one mode, is intended to suppress car-key signals, works with simple radio keys and KeylesGO systems, and has a stated range of 200–300 m. The page identifies testing and use by special services as its intended context.

EAS jammer is a separate product class

The category grid also includes the EAS-system jammer. Its exact RF/AM, range, runtime and supported-system data belong to its own product page and should not be merged into the car-jammer specifications.

What to compare before ordering

Check the required frequency set, product version, range stated for the exact model, power source, intended system and local RF requirements. Category values must not be assumed to apply to every jammer.

Source-of-truth rule

Existing human technical values, operating statements and product distinctions remain authoritative. This rewrite changes structure and language only; it does not normalize the standard and LONG products into the same specification.
