A friend gave me a few rfid kits awhile back never had a use for them until my ignition began to act up I figured I would give this a shot and see how it went! Turned out great there's a few ways to wire it up so that you will either have to flip a switch to turn everything on or just use the RFID to turn everything on I chose both options as I don't trust these old RfID kits fully just yet!

Parts you will need 4 relays I used 5 but you can get away with four you can purchase these online with harness that make the install a bit cleaner they can be purchased at your local bestbuy as well similar to the ones I used http://www.bestbuy.com/site/directe...lack/8014855.p?id=1156203597803&skuId=8014855
These are high amperage relays I suggest its own power supply from the battery however they can be powered from the old ignition supplyA cheap ol 12volt RFID kit they make various versions now days and can be purchased as low as 20$ this kit is a chip style not your proximity style like most newer cars using a battery these don't need a battery but the range is normally less than a foot the battery style can reach pretty far distances. One thing to check is the idle or stand bye current draw make sure it's below 150 ma this kit uses 3ma when on used.To save time here is a link on ignition removal you need the entire connection out of the car remove the small Phillips on the rear of ignition and remove the ignition and harness http://www.dsmtuners.com/threads/how-to-remove-ignition.133662/
This is the part we need the black plug will be retained so that I can reinstall a new key cylinder in the future as well as all your wiring can be done out of the car and just plug it in
Now a relay is not complicated to wire but people make it complicated pretty simple 86 - 85 are your coil one has to see ground one has to see positive voltage to engage the coil what your wanting to get out voltage wise these can be flipped would go on your 87 or 30 then the one you didn't use would be your output to your ignition wiring I.e the black plug seen above so here's a simple example

12v battery pin 87
12v from rfid output 86
Pin 85 gets grounded because 12v 86
12v output to ignition 30
87a is unusednow as far as your starter relay I found a nice button that fit nicely in my old key cylinder and ground it down to fit wired it to my relay and now I have keyless ignition system! All in less than two hours works great!

Good idea

Good setup, nice writeup. I've contemplated doing this with a powered 120bit rfid kit, and adding in electric locks on proximity or one touch, but they're a touch more spendy.

I plan to do a Bluetooth keyless setup and possibly change out the rfid to that but so far I like the RF stuff except if you have it worked on trying to explain how it starts

This is pretty cool!! You don't have to actually have that chip so close right?
Keys can stay in your pocket?

Not with this setup this is a non amplified RF system so I don't need to worry about batteries in a chip I mounted the reader below my ash tray I drop my keys in there they have amplified versions like new car style that work from a greater distance I'm just cheap

That is epic!!!!!

Very subtle, and slick!


Not gonna lie.... Im gonna do this.
I'm Sure I can achieve the final result with a stock ignition . Any disagreement?

Yeah I am gonna attempt a Bluetooth activation as well so that when I walk up to the car it will unlock and enable the start problem is my driveway might be to close For the Bluetooth but if I can get that sweet spot I'll be good

Advancedkeys sells a kit that's pretty nice. It has all the relays, push start button that pops into the ignition hole, if you choose to remove the ignition. Bought mine last year for another car but, never put it in. Planning on put it in my newly acquired Eclipse after getting security alarm and remote start installed.

seems like this stuff would make your car easier to steal.

This.

Neat nonetheless though.

It's all about what you do to it. A secret fuel pump cutout switch will stop people from starting the car. Thus preventing it from being easily stolen. But, if someone wants it bad enough, anything can be stolen. The idea of these products is to give you the luxury of newer cars' smart key set up. Imagine walking to your car, with the key card in your wallet or pocket, the car unlocks itself. Sit down inside and push start the car with your foot on the brake. No fumbling with keys. Wouldn't that be nice?

if the idea is to not carry key, what about mechanical ignition lock? is that being disabled?

I have always wondered how susceptible this kind of tech is to say a powerful solar flare interfering with it.

Also, do these systems only attempt to start while your pressing the start button or attempts to start for a given amount of time like say 3 seconds? (Obviously disengaging the starter once rpm exceeds say 500)

On the Advancedkey system, the mechanical ignition will need to be disabled or removed. A push start button will pop in where the key hole is on the steering column cover. It's been cold outside or I'd do it on my car and get pics. As far as security concerns, one can have an alarm system go along with it. And for extra measures, one can have a couple switches installed in line with starter wire, fuel pump wire, etc. maybe throw in a switch at the off position for a horn, so that when the thief trying all switches, he would activate the horn too. Can also be creative and set booby traps with that

I'm still curious if solar flares can interfere with RFID devices. I know they would interfere with SATCOMs. The worse the flare the more static there would be.

Im sure it would have to be a fairly big flare
And would probably act like how an electronic magnetic pulse would act in our atmosphere from a nuke
I wouldnt worry about it

Id be more worried about that tech savy guy down the street who specializes in rfid tech

Please stay on topic, guys.
