keys are old ways to open a door, and it will be difficult to use it in low light conditions so that why i moved to wirless with 20 meters range

Step 1: The First Systhem

The first system consisted of an interphone that requiered to push a button in the house to unlock the door.So it was simple all i a had to do is to apply a current to the door unlocking system to turn it open

Step 2: What Will U Need?

all u need:

  • 12 v dc power supply
  • RF transmitter (remote)
  • RF receiver
  • Somme wires

Step 3: WIRERING

IT IS TIME TO WIRE JUST FOLLOW THE DIAGRAM

Step 4: TESTING

Just press the button and see if the door will open!!!

<p>Kinda annoying this one (For me) I always wanted Central Locking on the house like my car, but Im too bloody stupid to figure it out. same as my Indoor nav for Shopping centres, You bet someone is working on an indoor GPS type thing for shopping centres.</p>
I think a short passcode would be nice to make sure only you could activate the gate.<br><br>ex; A,b,b,a
no one can open the gate but me<br>the recever will not accept any transmitter unless if i interduce him to the recever
<p>It's <strong>not about you accepting another transmitter!</strong> It's extremely easy to sniff and record a simple 433MHz code and then replicate it a later date, and your receiver will think it's your own transmitter being used, as it's a complete clone, so Like <strong>ThomasK19</strong>, I'll recommend KeyLoq from Microchip (it's &quot;code hopping&quot;, so never use the same code twice). Read more about it here:</p><p><a href="http://www.microchip.com/design-centers/embedded-security/reference-designs/keeloq" style="color: rgb(3,71,190);">http://www.microchip.com/design-centers/embedded-s...</a></p><p>Other key-hopper/rolling code security chips exists, but Microchips KeyLoq are solid and cheap.</p><p>Stay safe :)</p>
<p>Thanks for leaving the door unlocked! </p><p>Your private burglar</p>
<p>At least you should use a Keyloq transmitter and not a simple RF with two frequencies.</p>
<p>Great idea for a remote access system. It is also cool because you can unlock the door to let people into your apartment without having to get up and go to the door. </p>
thanks for your good review☺ and yes that was the point<br>
