i have no ignition key!

[xdream]

basically ive had my 240 and you can start the car with anything in the keyhole as long as you turn it

what can i do to fix it?

do i have to go find a new key hole and key? and if so what about my doors and trunk? will i have 2 different keys?

[s13swaaangin]

I dont think there is a way to fix it without replacing the whole key cylinder. If you go that route, then yea you will have 2 keys. unfortunately....

[xdream]

can i put like a engine start button or something creative since i have this problem already?

what kind of car do you have? a thief can easily pop the lock cylinder on the s13's so a working lock cylinder is not that useful. you should think about a killer relay. i have mine rigged so that car cant start without the cd player on and i remove face plate when not in car. you just need two relays. 12volts.com explains the procedure.

I dont see any point to start button and it would be hard to sell car as the person would have to learn a new procedure for starting car. youd have to have switches for accessory and run and momentary switch for start.

[s13swaaangin]

I could tell you how to wire the switches and relays youd need but, if your s13 is like mine, your steering wheel locks without the key. so youd still need to put the key in every time to start it. Now I dont know if since the cylinder's bad it bypassed this but even with switches your car is still gonna be very easy to steal. I would think about a starter kill or somthin along those lines....

That's right; be very careful about the steering wheel lock. Dont touch the ignition switch unless you want to take steering wheel off and remove the wheel lock. You can create a situation where the wheel locks while driving if you remove the ignition switch.

what do u mean dont touch the ignition switch? how else can i get a new key?

can u also describe in detail how to make a kill switch.

[vancouverbc]

the "ignition switch" is on the opposite side of steering wheel from where the key goes in. the "ignition switch" is the electrical switch" . you remove it by unscrewing a small screw. its ok to touch it . you just have to make sure you put it back before driving car. the ignition switch is not the lock cylinder. if you drive without the switch in place, it is possible for the wheel to lock while you are driving.

here are some instructions for killer relays. Search around if you want the killer relay controlled by cd player. Ask at 12volts.com for a their sponsor supplier that sells relays. you will get them cheaper that way and get the right ones. you should go to the tutorial on relays so you understand how they work. they are just a switch that is activated remotely.

you could also wire it up to say your parking lights so that when they're on, you can start it. Thats an easy fix and all you need is like a 30 amp relay you can get at radioshack. If it sounds like somthin you wanna do just email me for how to wire it up. [email protected].

[xdream]

that sounds pretty dope. is it possible to connect a kill switch to like my ac controls?

or does it need something to do with a 12volt closed connection. meaning its it always about giving power to the ignition switch thru something hidden in the car?

[vancouverbc]

You only need the relay closed for the few seconds when you are starting car so you would use a normally open relay. Turning on ac would close the switch and allow power to go to starter. If you stall in busy traffic, you'd have to turn on ac before you could start car. If you use a normally closed relay , you need continuous power to keep relay open and starter wire interrupted.

[s13swaaangin]

Im talking about wiring a relay so you have the ability to start the car with the parking lights on. You can use anything in the car that is a trigger. I.e. something that shows 12 volts or ground only when its turned on. Like your parking brake will show a ground only when its engaged, your parking lights will show 12 volts only when they're on. So youd just have to test the wires behind the ac and see if anything is triggered when its turned on. I havnt had to test them for anything so i wouldnt know...

i looked into changing my ignition cylinder at school once and there is a computer program that has instructions how to do things. well it is a PITA, its not a unbolt bolt in kind of thing. i dont remember exactly but there are like bolts that you have to snap off and a bunch of bs. dont do it your self. take it to nissan then they can possibly get you the right key/lock combination so you still have one matching key.

I want to try to do the kill switch with the cd player, but I'm not having much luck with the diagram on the12volts.com... could anyone explain in n00b terms what this means lol and what extra peces I need to get, thanks

This is the diagram for cd player:

You can substitute the switch with a number of others devices such as the amp turn on lead of your head unit. Be sure to isolate it with at least a 1 amp diode. Turn the key to the run position. Allow the head unit to come on or turn it on. Now start the vehicle. If you connected to the power antenna lead, make sure the tuner is on. If you have a pullout or detachable face head unit, your vehicle will not start without it.

This explains how a relay works. I think you need a diode and 2 relays for cd player.

[s13swaaangin]

why would you need the 2nd relay? It looks like its just being used to strengthen the turn on lead but i dont think thats necessary.......just my thoughts.

[vancouverbc]

These relays are designed for higher amps than what the cd player provides. If the 12v from the ignition is not supplied to terminal 30, the relays buzz. Of course, in this situation, the cd player has to energize two relay coils without help.

[s13swaaangin]

If your using the amp turn on, you should only need one relay. SPDT relays use less than 200 milliamps to trigger the relay and you can pass usually at least 15 amps through them if not up to 80. It will take nothing away from the wire or cause a short if used. At least I cant see how. I'm just passin on stuff I know as a car audio guy so you dont over-engineer somthin, and save you some time....

i have mine rigged so that car cant start without the cd player on and i remove face plate when not in car.
