RFID Ignition Lock Anyone?

I'm more interested in the battery free RFID fobs - similar to clothing tags. Hide the RFID sensor coil behind the dash near the key switch.

I know there is no such thing as theft proof. I believe in "locks are there to keep honest people honest". The idea is to take the machine out of the low hanging fruit category.

Problem is those tend to be momentary. They might be used to activate a door opener for example. You would need another holding relay to keep the ignition active while the vehicle is running.

The old school things I used to do are either on or off, full time.

I'd expect a proximity circuit that occasionally polls for the fob or only requires the fob to start the engine, not a latching relay based on the fob being continuously present. Kinda like my prius...if I forget to hit the off switch I can walk away with the keys and somebody can drive away in my car!

While the old school devices like the phone plug would have to be deactivated manually (plug removed), there are simple ways to use a latching relay type system.

A door/gate entry type FOB reader could pull a relay which is wired to latch. Latch power would need to be from a point in the vehicle that only has poweer when the key is on. That relay would release when the vehicle ignition is turned off.

Key On >> FOB detect/latch >> key to start. Vehicle would run as long as the relay is latched. When you park and leave the vehicle, turning the key off drops power to the latching relay.

Something as simple as this would work:

That gives you the controller and keypad all in one unit, plus the FOBs. All you'd need to add would be the relay and those are easy to find and inexpensive.

I just wish they would chip me! Like a Dog! I would love to be able to walk up to something, anything and not have to go thru all the security BS.

I know someone would immediately hack it but....wouldn't it be nice?

I also wish they could figure out away to insert my cell phone under my skin so i'm not always grabbing for it! It's always in the way but never convenient!

Couldn't you just use one of the premade kits out there... this is just one of them but there all over amazon, eBay, etc... Just a thought...
