electronic nerds please help.

ok so hang with me here...

i want to do a keyless push button start.

i also want it to be like a rfid keyless start.

i was planning on picking up some sort of key card much like the 6's have in their cars stock along with a reader.

i wanted to connect the button to the ignition system but somehow splice the rfid reader to the ignition so when i get into the car i can just push the button and go.

first off is this possible?

is there a way to deactivate the steering column lock and would i need an acc switch or ignition switch?

im not sure how vehicles like mercedes and hondas s2000 work with these but know if i could do this by myself i could do it for less than 100 bucks while the guard dawg system is more like 400. thanks everyone.

if i used the rfid card i could leave the ignition switch on so it wont start without me. but i may need that acc switch either wway.

something like this maybe installed with the button?

the tag is good for up to 6" so when i enter the car i would more than likely attach the module under the coin tray in the center console so when i enter the car i throw the card into the top console and take off. i just dont know how i would install this inline from the ignition source to the button so the rfid module would allow the button to be active. this sounds great in theory but i need some help on creating this.

if it all goes well i could start to sell these to other members for more than likely hundreds under regular costs. anyone give me a hand here?

bump on the help...

The hardest part is getting around the steering wheel lock. You would have to either remove it completely or install a solenoid to disengage/engage it as necessary. The rest is just getting hold of the appropriate wiring diagrams and splicing in some relays, a momentary switch (the push button) and the electronics.

Buy a new Mazda3 that has this stock... problem solved. That was easy.

yea then i could have an ugly car with a cool option....no.

im glad you came up with that idea though...it was helpful

now i do have a question about the steering column lock. this is in place to create an ignition lock right? this has no other effect besides to deter theft correct? removal of this would be of no real safety concern besides theft which wouldnt be necessary if i had a push button rfid starter? hmmm...i think i may have to have someone help me combine a few wiring diagrams to get this up and running. as for sale i think the removal of the steering lock or addition of a solenoid would make this quite a non deseriable item for most.

i will get with "my electrical guy" this weekend and come up with a hypothetical diagram and post it up for speculation and get the 411 on thoughts and ideas.

comments are welcome if you have any other info or ideas to add.

Not much help, but you're not the only one in search of this.

Might be something to watch!

I did this in my RX8. However I still needed they key to disengage the steering column lock as it was mechanical and I am 99% sure it is the same here.

I wired it so that it would NEVER start with the key, and only with the push button start. It still needed the key turned to the ON position and the clutch depressed to start. Worked great and I didn't find it annoying at all.

Sorry, but that sounds really annoying! Creative but I no longer see the point if you still have to take the key out of your pocket and stick it in the ignition.

that was my thought. thats why i wanted to do something with the rfid so i didnt have to use the key anymore. otherwise the push button is usless. i would just finish the key rotation and save myself money and hassle. i just have to figure out a wiring diagram and see if it would work.

 

[mazdaspeed32007]

if anyone could come up with a hypothetical wiring diagram i would appreciate it greatly. heres some information on the car and rfid module and starter button. its a matter of wiring the whole thing together so it would work when the rfid module is activated by the rfid card. thanks to whoever can take this on. keep in mind the accessory and ignition would have to come on when the rfid reader is activated.

something like this maybe?

anyone wh can add to this or correct it would be appreciated.

this is the basic diagram i came up with. now i would still need to know what wires to cut/splice into in the ignition so it would complete the circuit in the actual ignition....but i think everything else works out here....as i said...correct me if i did this wrong please.



the activated rfid module would allow the power the acc and ignition so all i would need to do is push the button to start it up.

1) Your second link doesn't work.

2) How do you plan on bypassing the mechanical steering lock?

second link fixed. and as far as ths eteering column goes....im not sure yet. im going to take the car to sun and sound tomorrow moring whenever i get up and ask for some assistance and get some info on the ignition

 

[mazdaspeed32007]

ok so sun and sound was of no help. you shouldnt touch that stuff....its like a beginner piano player trying to perform in an orchestra. thats wat they said to me. you dont know me asshole! lol.

all i need is a way to work the accessory without the use of a switch so the rfid module would allow the acc to turn on. im assuming i would have to have a relay activate when the rfid module allows the relay to power the acc. but im not quite sure how i would wire this.

I was referring specifically to the lock that prevents turning the wheel, not the keyed lock in the column. Ideally you would wire the system so that you can start the car by either the RFID/button, or the key in the event the RFID fails. Don`t forget to make sure that moving the badge away from the field does not cause the car to shut off.

if the car shut off upon moving the badge away it wouldnt really bother me because if i needed to put it within 6 inches to activate it then it would already be out....so i would just drop it in the tray.

as far as the column lock goes....ive been looking into this and removal of the steering wheel to pull the pin and spring is on option but not ideal.

the other thing i could do is make a dummy key that wouldnt start the car but would at least turn the key to acc on to unlock the wheel lock. now i would probably grind down the end of the key so i could fit something over the key slot so it wouldnt be seen (which is what i was planning to do but i would have a key under there.) if the acc turned on with a dummy key cut from like walmart or something i would disconnect the acc so it would only work with a switch or relay with the rfid reader.

now i think these keys have chips in them so you cant start the car without the real key. do they even turn if this is true? anyone know about this?

Until the first time it slides out of position when you stomp on the gas or throw the car hard around a corner.

How does the '10 model get around the steering wheel lock problem?
