How do i reset or bypass starter kill on a 2008 saturn astra after replacing the battery and charger?

If starter won't crank the engine when problem is ongoing? Make sure battery has a full charge and connections all good. Jump the starter relay, pull the relay, use jumper wire on switch side of relay, left side in diagram, cavities for terminal 30 and 87. The starter motor should crank the engine, that starter fuse is hot all the time. If you try the jumper, make sure transmission is in park or neutral and parking brake is set. Vehicle can't move. If you have key in on position, where dash lights come on, when you use the jumper, depending on the problem, the vehicle may start and run. By using the jumper you are bypassing the control side of relaY. right side in diagram. There are several components involved on the control side of relay, ignition switch--bcm--ecm--neutral switch. You need to have it diagnosed properly. Have you tried cranking in neutral instead of park, when problem is ongoing?

Since you're talking about a valet mode you are likely referring to an aftermarket remote starter system. Since you didn't provide details on the make and model of remote starter it's difficult to say whether or not the valet switch can be bypassed by some menu option or if you need to short the wires across the switch. Since apparently the vehicle is in valet mode currently due to the broken wire, that would suggest the switch is a Normally Closed type in which case the easy bypass is probably to cut the other wire at the switch, strip the wire insulation on both, and twist them together until you have a chance to get both wires soldered back on. If you go this route, but sure to insulate the wires.

I think you ether missed a wire or miss placed a wire and have a short or no connection where you need one recheck all wiring on starter make sure there is no lose wires

of course!...however you do not want to bypass this safety switch! bypassing it will allow a car in gear to start...possibly running over and/or killing someone! get a cheap switch at a salvage yard!

if your power going to starter from ignition switch ,your starter has to be faulty or main wires on starter has bad connection

It would be the ignition or those ignition wires because of the kill switch being poorly installed, id try tracing wires first and replace anything thats been cut/spliced into. if not change the ignition

There is NO kill switch on the 2000 Elantra... HOWEVER, there is a thing called the Key Fob (keyless remote entry system). There is, however, a system in place called the 'starter kill' circuit and it is activated when the burglar alarm goes off.... it's called the burglar alarm relay and it is activated to prevent the engine starter system from being used. There are three ways to get the engine started in such a circumstance... 1. use the key fob to 'disarm' the system... 2. put the key in the ignition and turn it to the 'RUN" position and wait until the alarm stops (horn stops beeping and the parking lights stop flashing), then the engine will start.... 3. pull the starter relay from the UnderHood junction box and bypass the starter circuit (key in ignition and in the 'RUN' position), jumper the starter solenoid circuit to energize the solenoid to start cranking the engine -- it should start then.

This is a Direct Fault Caused by the Alarm System Starter Kill. Do you have an Alarm Override Switch???? You may need the Dealership to Reset the Alarm if not.
