NRF24L01 to replace key fob

Projects General Guidance
1

Afternoon all,

I have a problem where my access key fob does not have enough range for the receiver to detect it, the key fob is as per the below;

If possible I would like to use the Arduino Nano + NRF transmitter to, effectively, replace my keyfob.

I am new to this so not sure if it is possible or how?

I believe the fob will have a default pipe or tunnel to the receiver and then have its own specific ID?

Any help would be appreciated!

What distance do you currently get and what distance do you require?

You will also need an nRF24 as a receiver.

Have a look at this Simple nRF24L01+ Tutorial

Thanks for the replies,

I was looking to use 1x NRF and the existing receiver of the net2 box? Otherwise I could just use 2x NRF and connect the receiver with an Arduino to use the digital output to activate the gate.

You literally have to touch the receiver with the fob for it to work, I was thinking a couple of meters range and is just to test what can be done etc.

How secure does it need to be - do you need rolling codes etc?

No secure at all really, I already have the code that is within the fob and the fob is on the same Hz rating as the NRF, i basically thought use the NRF in the fobs place?

Unless your receiver claims to be compatible with the NRF24L01, it won't work.
There are a multitude of wireless standards all incompatible with each other.
