Keyless Go Repeater According to its functionality, it has several modes of operation:

  1. How it works with vehicles equipped with Keyless Go systems Toyota all model  (2009-2020) Lexus all model  (2006-2020) Subaru all model  (2008-2020).
  2. Multi-brand operation mode with cars equipped with Keyless Go or Keyless Entry systems of other brands until 2017-2019 additionally.
  3. Operation mode with cars equipped with the FBS4 system, brands Audi until 2020 and Mercedes-Benz until 2018 opening and launch, 2018-2020 just starting cars.
  4. Mode of operation "Multi-brand 868" with cars equipped with the system Keyless Go or Keyless Entry in which the key works on a frequency 868 Mhz, in particular, the BMW E - series (BMW F - Series only were the key to 868) and some cars VAG - Group.
  5. Working mode with TESLA Electric Car brand cars until 2018. (up to plastic keys that look like a credit card).
  6. Mode of operation with BMW F - Series and G - Series cars with the ability to find and detect the key in the radius of the big unit. on the principle of the car, first reading the request from the car handle. (All the keys G - Series in 1-3 minutes without moving to go to sleep find a key after this is not possible as well as to start or open the car)
  7. Mode of work with cars Brand Nissan - Infinity 2017 to 2020.

When working in the first mode of Toyota/Lexus/Subaru there is the DETECTION AND DISTRIBUTION of the key. In other words, the operator of the big unit sees the presence of the key in the working area of the device. Just as in the mode of the BMW, only for BMW you are not looking for all the keys of this brand around you, and directly in advance coming to the car handle and reading the request in the memory cell you are looking for only the key of the car you are interested. The request is not wiped it remains in the cell.

The range of communication between blocks up to 300 meters with a dense building/work from the premises, etc. It is important to understand that this is the reserve of power to normally transmit a signal in any buildings and obstacles. And the actual operating range is limited by the range of the radio channel between the key and the car, and is on average 100-200 meters and rarely exceeds 250 meters!!!! The range of the radio channel also depends on the battery charge in the key. Reserve on the communication range between units is necessary for stability, although many manufacturers neglect it. For example, the work is done from the front door at the back of the house, and the key is in the apartment window which overlooks the courtyard where the car is. As a result, there are no walls between the key and the car, and between the small and large blocks there is a reinforced concrete wall, and most likely more than one. Without a reserve of communication between the blocks in this situation, it is impossible to work. A good reserve is necessary even in a busy parking lot.

Also, an important advantage is that it is not necessary to precisely position the small block in the car. The operator simply sits in the car on his own and drives away. The work of the small unit is similar to the key: it can be placed anywhere in the cabin.

Constant improvements and updates are being made, and tests of the device work on each car. All updates and tests will be available in the news section and on our YouTube Channel.

The device consists of two repeater modules - receiving and transmitting. The receiving module must be located at the car, the transmitting module at the key. After activation of the system, a data transmission channel is established between the modules, which allows you to retransmit vehicle requests 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 (it has an antenna installed).

The transmission module of the large block must be located at a distance of 6-13 meters from the key and aimed exactly at the key, at this time authorization will take place and the car can be opened and started. (If the antenna plane is directed away from the key, the key's radiation range may be reduced)

With the help of additional enlarged antennas, it is possible to achieve a range of key radiation up to 15 m.

The delivery set includes two blocks, a large and a small one, and a charger.

On devices manufactured by our company, you get 1 year warranty, service, current updates and after-sales service.

  1. Distance from the key to the built-in key - Toyota/Lexus/Subaru 10 m (minimum 9.3 m)
  2. Distance to the built-in key - BMW (series F, G) and Porsche 12.5 m (minimum 11.5 m)
  3. The distance to other built-in keys (including BMW E) is 5-7 m

When assembling an external pluggable antenna, the distance from the large unit to several frequencies is 50 to 70 percent compared to the built-in antenna. When working with a removable external antenna, it must be stretched and given a square shape.
