Simply Key & Phone Blocker — Advanced Protection Against Electronic Theft and Signal Hacking

In today’s digitally connected world, the security of your electronic key fobs, mobile phones, and access cards is more important than ever. Simply Brand’s Key & Phone Blocker provides state-of-the-art protection by effectively blocking a wide range of radio frequency signals, preventing unauthorized access, hacking, and data theft. This compact, portable device is an essential tool for anyone seeking to safeguard their personal and vehicle security from increasingly sophisticated wireless threats.


Product Overview

The Simply Key & Phone Blocker is designed to act as a powerful shield against all common wireless signals, including Wi-Fi, GSM, LTE, NFC, RF, and many other frequencies. By creating a secure Faraday cage environment, it stops signals from penetrating from outside or escaping from inside, ensuring that your devices remain completely isolated and protected at all times.

This blocker is ideal for protecting:

  • Car keys and electronic key fobs (including smart key systems)

  • Mobile phones and smartphones

  • Building access key fobs and security cards

  • Smartwatches and fitness trackers

  • USB thumb drives and Wi-Fi cards

  • Remote controls and other RF-enabled devices


Key Features & Benefits

Comprehensive Signal Blocking Capabilities
The blocker’s advanced design neutralizes signals across multiple wireless standards—Wi-Fi, GSM, LTE, NFC, RF, Bluetooth, and more—making it impossible for thieves to remotely access or intercept the signals from your devices. This significantly reduces risks such as car theft via relay attacks, digital identity theft, and unauthorized building access.

Multi-Device Compatibility
Large enough to accommodate several small devices at once, this blocker ensures all your valuable electronics stay protected in one place. From car key fobs and smartphones to access cards and remotes, you can secure multiple items simultaneously without needing separate blockers.

True Faraday Cage Protection
The device functions as a Faraday cage, a proven method for blocking electromagnetic fields. This means no radio frequencies can pass through its walls, creating a secure ‘signal blackout’ zone for your devices—making hacking and tracking attempts futile.

Portable, Lightweight, and Convenient
With dimensions of 25cm (length) x 12cm (width) x 1.5cm (height) and a lightweight design (only 70g boxed), the Simply Key & Phone Blocker fits effortlessly into your pocket, handbag, or briefcase. Its slim profile means it can be carried discreetly and comfortably anywhere you go.

No Power Required
Unlike electronic signal blockers that need batteries or charging, this blocker operates passively. Its signal-blocking capabilities require no external power, maintenance, or activation—just place your keys or devices inside, and protection is immediate.

Durable and Sleek Construction
Built with premium materials, the blocker is designed to be both robust and stylish. It offers lasting protection while maintaining a modern, minimalist look that suits professional and personal environments alike.
