The practical button key is our standard key for all GEMINY security products, each product is supplied with three keys.
The GEMINY key with its patented double pin technology is the core element of all GEMINY products.
At the production of standard keys of cylinder locks the key blanks are milled or drilled.
GEMINY has flipped this principle – as the only system in the world.
For more comfort you can use our GEMINY combined key instead of the standard key.
It connects the GEMINY key with your cylinder key and offers best handling
