How the Locksmith Uses the Keyless Go Repeater FBS4 to Start the Car

• Step 1: Access the Owner’s Key Fob
  • The locksmith must have access to the vehicle owner’s key fob or at least the signal from the key fob. If the key fob is still in the owner’s possession but the signal is too weak to reach the car, the locksmith can use the repeater to amplify the signal.
• Step 2: Amplifying the Signal
  • The locksmith places the key fob within the range of the Keyless Go Repeater. The repeater amplifies the signal from the fob and transmits it to the vehicle, simulating the presence of the key near the car. The repeater essentially acts as a relay to pass the signal to the vehicle.
• Step 3: Unlocking the Car
  • In most keyless entry systems, the first action is unlocking the car. Once the amplified signal is received by the car, it will unlock the doors (if applicable). The car may also recognize the signal and allow the engine to start, depending on the system.
• Step 4: Starting the Engine
  • In many vehicles, once the car detects a valid key fob signal (even if it’s amplified via a repeater), the engine can be started. This might happen in two ways:
    • Push-button start: The owner can push the start button while the repeater relays the signal from the fob.
    • Traditional ignition: For vehicles with a keyless ignition system but still using a traditional ignition (without a button), the repeater can act to amplify the signal to engage the immobilizer and allow the car to start.

This device allows you to open and start the car equipped with Keyless Go, Keyless Entry at a distance of up to 300 meters.

Below are the legal and legitimate ways a car locksmith could use the Keyless Go Repeater FBS4:

1. Unlocking Vehicles (with Owner’s Consent)

• Authorized Unlocking Services: If a car owner is locked out of their vehicle and the vehicle uses a keyless entry system (e.g., “Keyless Go”), a locksmith may use a Keyless Go Repeater FBS4 to amplify the signal from the owner’s key fob to unlock the car. This is especially useful in situations where the key fob’s signal might be too weak to reach the vehicle.
  • For example, if a key fob is out of range or if the owner has misplaced their fob but has authorized the locksmith to assist, the locksmith could use a repeater to help gain access to the car.
  • The locksmith would need explicit permission from the car owner or be working under a valid service agreement to perform the unlocking.

2. Testing Keyless Entry Systems (with Owner Permission)

• Security Assessments: A locksmith may use the Keyless Go Repeater FBS4 to test the security of a vehicle’s keyless entry system at the request of the owner. If the car owner is concerned about the vulnerability of their vehicle to relay attacks or other forms of unauthorized access, the locksmith can use the repeater to simulate an attack and evaluate whether the vehicle is susceptible to such threats.
  • This type of testing helps the locksmith understand the weaknesses of the system and recommend additional security measures to the car owner, such as using faraday bags, updating the vehicle’s software, or installing additional anti-theft devices.
  • This would only be legal with explicit consent from the vehicle owner.

3. Providing Emergency Services

• Emergency Unlocking Services: In emergency situations where a car owner has lost their key or is locked out and the car has a keyless entry system, the locksmith may use the Keyless Go Repeater FBS4 to assist in regaining access to the vehicle. This could be crucial if the car’s key fob is out of battery or if the signal is obstructed by distance or interference.
  • Emergency locksmiths are often called in situations where traditional unlocking methods are not feasible, and the Keyless Go Repeater can help bridge that gap for certain models of vehicles.

When operating in Toyota/Lexus/Subaru mode one, there is DETECTION AND DISPLAY of the key. In other words, the operator of the large unit sees the presence of the key in the working area of the device.

Communication range between units is up to 300 meters in dense buildings/working from a room, etc. It is important to realize that this is a power reserve to normally transmit the signal at any buildings and obstacles. And the real working range rests in the range of the radio channel between the key and the car, and is an average of 100-200 meters and rarely exceeds 250 meters!!!!. The range of this radio channel also depends on the battery charge in the key. Reserve on the range of communication between the blocks, is necessary for stability, although many manufacturers neglect it. For example, the work is carried out from the front door from the rear of the house, and the key is in the apartment windows which overlook the courtyard, where the car. As a result, there are no walls between the key and the car, but between the small and large block there is a reinforced concrete wall and most likely more than one. Without a margin of communication between blocks in this situation, operation is impossible. A good reserve is necessary even in a busy parking lot.

Also an important advantage is that it is not necessary to position the small unit precisely in the car interior. The operator simply gets into the car as if it were his own and drives away. The operation of the small block is similar to a key: it can be located anywhere in the cabin.

Working principle The device consists of two relay modules – receiving and transmitting. The receiving module should be located at the car, the transmitting module at the key. After switching on the system, a data channel is established between the modules, which allows retransmitting requests from the car to the key and back.

The following conditions must be met for the system to work:

The receiving module of the small unit must be located 10-30 centimeters from the door handle (the antenna is installed in it).

The transmitting module of the big block should be located at a distance of 5-7 meters from the key and directed by the plane to the key, at this time will be authorization and you can open the car and also start it. (If the antenna plane is directed away from the key, the range of irradiation of the key may be reduced).

With additional enlarged antennas it is possible to achieve a range of irradiation of the key up to 15 meters.
