What is GSM-KEY?
The GSM-KEY System is an advanced secured system that is based on
the cellular network, The GSM-KEY system works with Caller ID and
when an authorize number calls, the system will recognize the
caller and open the gate, While it will not answer the call as the
call will not cost anything.
How does it work?
GSM-KEY incorporates a professional industrial grade GSM engine
that receives calls at its SIM number, as any ordinary GSM phone.
You need to use any operator that operates in the 900/1800 MHz
band, that is the standard in most of the world, Just to give an
example, if your SIM has a phone number 35674564, that is the
number you have to call to open the gate. GSM-KEY has a memory
where you will store the numbers of people enabled to open your
gate (up to 200) When GSM-KEY receives a call, it will check the
calling number and if the number is in the list you have prepared
it will reject the call and open the gate.
Does it work with any electric gate?
Yes. All electric gates have a button that is used to open them.
GSM-KEY has a relay whose contact has to be connected to the
oopening button. Actually it pushes the button in your place.
Does it cost me anything to use my phone to open my gate?
GSM-KEY doesn't answer the call, it simply checks the caller ID.
Your network must send the caller ID otherwise GSM-KEY won't work.
Usually operators don't charge until you answer the call, so it
won't cost you anything to open the gate with GSM-KEY.
Of course you need to have an active SIM inside it, and this may
have a monthly fee regardless of the calls.
Check your local operators for these details.

password, to GSM-KEY, indicating the phone number to enable, and
