Hoping for an idea or pointing in the right direction.
Right now I have a switch hidden in my truck that disconnects the starter, so without hitting it (hidden) my truck cant even be started with the key. What I'm hoping to do, and this will be my first real 'make' is setup some kind of proximity sensor. Whether it be an RFID on/off switch so that I can keep a RFID card in my wallet. Or something else like a bluetooth switch that I can activate with my phone.
I'm hoping one of you could possibly point me in the direction of a proximity switch I can setup fairly cheaply that uses SOMETHING that I keep on my body at all times (in my wallet, phone, maybe even a necklace/magnetic ring that I swipe for on/off) that will prevent my truck from starting even if someone has stolen my keys. I've already got everything ready in my truck. Starter wires extended and hidden in a certain place with a decent amount of room inside the cab.
ANY ideas will be helpful. I've always been a tinkerer, but I want to become a builder. I chose this as my first real project and would really like to see something come of it.
To clarify what I'm asking for... I hope to be pointed in the cheapest, easiest, direction on how I can get this done. Hopefully from there I'll be able to research what it takes to actually do it.
But make a small switch, when it receives the lock command it shuts a switch off. When it receives the unlock command it 'flips' the switch on? Should be able to take the keychain apart and put the rfid tag in my wallet. Which is what I'm looking for.
I have an older jeep, 4wd, no door locks, half the time it doesn't have doors. so I don't actually NEED the function of this.
Would this be feasible? I was really hoping to make it from the ground up, but after some reading I'm not entirely sure how easy that would be.

Cheapest & easiest would be to use a hidden reed switch. Carry a magnet on your key-ring, & when you put the magnet in the right place, your system is activated.
