remote start in an 07 ion3

Most Ions use the hybrid Passlock circuit where a 555L will not work... use a 556L or better yet a PLJX from trilogix.....

They simply call it "Passlock" on the Ion.

It's a different system from Passlock I or Passlock II.

The 555L should work fine, though. I use the nearly-identical Audiovox AS-GM4 on those cars with no trouble.

You can also use a resistor and a relay, although it takes longer. If you search the www.carsound.com/forum security forum, you should be able to find the resistor method.

DEI has a special bulletin about how to use the 555L on the Ion, as well.

thanks for the input.

This vehicle has a special version of passlock 2 that one wire controls the starter, accessory and passlock resistance. The dei 555lw and the bypasskit.com plxr are what you need.

You only need one Passlock bypass. 555L will do it. Not familiar with the PJLX, but regardless, if you buy one, you don't need the other.

When you install your APS-996A, remember that there isn't a way for the aftermarket unit to control the Saturn's factory alarm.

Set the factory remotes aside and stop using them. Also couldn't hurt to get out the Saturn's owner's manual and go into programming and disable the factory alarm altogether.

Look into the bypasskit XK810 unit it is a remote starter with all bypass and doorlock features all in one that runs throught the data. I think the unit is available for the Saturn. It is an upgradeable unit.

thanks for the info. i ended up getting the 555LW by DEI. Anything different about the door locks?

Here's the fastest/easiest/simplest way to do the locks. I install Audiovox every day, and do a lot of Saturns.

First, locate the car's lock/unlock wire. It's white. You can get it coming in from the driver's door, but also along the doorsill running to the rear of the car, with the parking light and brake wires. It's going to be a lot easier to get it in the doorsill.

It'll test as a straight ground when you press lock on the door panel, and a partial ground for unlock.

From your 996, get the following things: The 4-pin auxillary harness, the 3-pin doorlock harness, the package of resistors, and the diode pack (the diode pack is in the black shrink tubing, packaged with the on/off control switch.)

From the resistor pack, take the resistor with the lowest value......it's all the way on one end of the pack......measures around 3-400 ohms if you're using a meter. Discard the rest.

On that diode pack, it has one end with a single wire, and another end with two wires. Cut off ONE wire from the double end, discard it, and tape off the exposed wire coming from the diode.

You DON'T need the following:

From the lock harness: red-lock, RED / black-second unlock

From the four-pin harness: BLACK/ blue, BLACK/ red, BLACK / YELLOW.

(Unless you choose to use the BLACK/ red to pulse the car's doorpin wire, to shut off the Saturn's radio after remote start shutdown.....but the radio times out after a little while anyway.)

Take the green unlock wire, connect it to the resistor.....connect the other side of the resistor to the SINGLE end of the diode pack.......connect the other end of the diode pack to the white wire in the car.

Take the GREEN/ black pulse-after-start wire, and connect it DIRECTLY to the white wire in the car, with NO diodes, relays, or resistors.

Although the GREEN/ black pulses after starting, it also pulses when you press Lock on the transmitter. Just remember that every time you remote start the car, it's going to also lock itself.

P.S. Again, don't forget to turn off the Saturn alarm. When you enter the Saturn's programming menu, you have to listen for a chime...........if you keep the door closed and the seatbelt fastened, you won't be distracted by the belt/door chimes.

double check on the key itself some of the new gms have a new style of passlock ( if the key has a plus on it just under the plastic it requires 2 bypasses a 555L and a 556U it is a pain in the ass but it can be done

someone wrote that you cant interface with the factory alarm that is not quite true it is possible however it is quite tricky because it uses RF frequency it must be done via the factory remote if you are willing to you can hook up you arm and disarm wires from the aftermarket starter  to the factory remote and it will trigger the lock and arm as well as the unlock and disarm i have done this it is a pain in the ass but the customer i i did it for was willing to pay for it so i am always willing to try

this is just a side note and i wouldnt recomend this to someone just starting you risk messing up the factory remote if you dont test the wires 100%
