Im trying to fix a security light and have wired it into the house and am now stuck at a two way switch in my hall!i've bought a triple two way switch so i can isolate the outside security light the other two switches are for my hall and landing lights how do i do it?

You may have a key with a chip in it so you will need to hold the old key that has the correct chip in it next to the ignition switch when you try to start the car.

If the thief damaged the 2 wires going down the column from the sensor ring those will have to be repaired. That is what picks up the signal from the key to tell the car to start.

Passlock
The passlock system is a vehicle theft deterrent system which deters drive-away vehicle theft by disabling engine operation if the ignition lock cylinder is not rotated with the proper mechanically cut key.
The passlock system is made up of an ignition switch assembly, passlock sensor, body control module (BCM), instrument panel cluster (IPC), and a powertrain control module (PCM).
The ignition switch contains a magnet mounted on the lock cylinder and a passlock sensor assembly which consists of security hall effect sensor, tamper hall effect sensor, and output resistors. A drill proof metal shield is also staked over the sensor housing.
The passlock sensor mounted to the ignition switch assembly is located inside the upper right side of the steering column. The passlock sensor contains two hall effect sensors: a tamper hall effect sensor and a security hall effect sensor. The tamper hall effect sensor is mounted on top of the security hall effect sensor. Should someone attempt to defeat the system by use of magnetic experimentation, the tamper hall effect sensor will activate first.
The BCM has the passlock controller integrated into it which controls the majority of the security systems logic. The BCM reads the data from the passlock sensor continuously. If the data is correct and has been received by the BCM within a specified time, the BCM will send a coded password to the PCM. The PCM will then allow the fuel injectors to operate.
The coded password for the security system is sent from the body control module to the PCM via the class 2 data link. If the password is correct and received within the specified time, the PCM will allow the fuel injectors to operate.
The IPC contains the security telltale. The security telltale has three modes of operation, OFF, FLASHING, and ON.
SECURITY TELLTALE will be off if:
?€¢
Ignition is in the OFF position

?€¢
Ignition is in the RUN, START, or ACC position and security system diagnostics have all PASSED

SECURITY TELLTALE will be on if:
?€¢
The BCM is performing a bulb check at vehicle start

?€¢
Security system diagnostics have not yet completed at vehicle start

?€¢
A security system diagnostic trouble code (DTC) is set in the BCM or PCM

SECURITY TELLTALE will be flashing if:
?€¢
The tamper hall effect sensor has been triggered

?€¢
Incorrect passlock sensor data to BCM for more than 5 seconds during vehicle start

?€¢
No passlock sensor data to the BCM for more than 5 seconds during vehicle start

?€¢
Incorrect password from the BCM to the PCM after 5 seconds during vehicle start

No ,the box is probably not bad , but you need to have it programmed . The dealer is the only one that can do that ? The keys don't matter .

Sorry but you can't just replace parts , you need to know how the system works . You need to take this to a ASE certified repair facility that knows how it works .

It should be;
black wire to brass screw.
white wire to the silver screw.
bare wire to the body of the switch or ground.

You have a triple switch that controls bathroom heat, fan, light combo.
When lights are off inside room, and you flip the heater switch, you see a flash of light inside the switch.

The switch is mounted in electrical box. If flash is inside the box where electric wires are, then that is NOT normal and should be looked after by checking connections and securing wire nuts.

If the flash is inside the switch, then that can be normal. But it also might be time to replace switch if switch is old.
What happens inside a switch is that 2 brass connectors come together.
The amp draw from heater is large, so a lot of electricity suddenly passes across the brass connections and produces a flash of light.
If flash is accompanied by a sound, for example crackling or fizzing, and/or you smell electrical burning, then that indicates the switch needs to be replaced.

At this point either. Once you hook up the switch test the switches on both sides. Make sure each one turns on and off if that makes sense. If the blue wires are on wrong one switch will only work if the other one is on. If that happens reverse the blue wires and that should fix it.

I answer questions for free.
I know electric wiring and can help.
But you need a better explanation.
What are you doing?
Did you replace something.
What device did you put in?
Is this a 3-way device at one end of a hall?
And I'm a little unclear about " all house lights on light the hall but all off will not turn off the lights'
If you add a comment I will answer

The white and the black wires are both hot wires, and the green wire is for earth ground only. The green wire does not belong hooked up to the white wire.

The two black field wires should be attached to one side of the dimmer switch (one of the black wires from the dimmer switch)

The white field wire should be attached to the other side of the dimmer switch (the other black wire from the dimmer switch)

The green wire from the dimmer switch should be hooked up to earth ground only (any un-insulated copper wire that is inside the switch/outlet housing) and if you can not find it attach the green wire to the inside of the light switch outlet housing and be sure that it is attached to metal.

The other hall light switch that you are talking about must be connected inline with that light switch you trying to turn into a dimmer, and it should operate again nomally once you have connected that light switch properly, and if not check for any tripped circuit breakers.

I suggest you cut 3 pigtails out of your black wire (about 5-6" each and strip them so you can put a nut to tie them all together on the main wire, then do the same for your grounds using green 5-6" strips of wire and then connect all 3 switches with the pigtails to their proper locations. This WILL fix your problem.
