Kia Factory Alarm Bypass Possibly Found

So far its working ok. Just ground the factory hood pin and the alarm will not arm since its seeing the hood is open. Power locks continue to work normally only with the factory key fob the lights do not blink indicating the alarm is not setting. If you wish to keep the factory pin working for an aftermarket. Find Pin C5 on the ETAC cut the wire and ground the wire going into the ETAC unit and connect the other end to the hood pin input of the aftermarket alarm. Safely stow away that bulky key/remote and enjoy your new alarm. I am not totally positive on the pin out at the ETAC so I will include the diagram so someone can correct me if the information is wrong. This is for the 2002 Kia Optima SE with factory theft and key less.

Why not just hook up disarm?

For as long as I can remember no one has been able to find the right wire that will properly arm and disarm the factory alarm system. It arms when you lock it with the factory key fob or if you lock it from inside before closing the door. If you unlock using an aftermarket alarm or remote start it sets the factory alarm off. I believe this true for allot of Hyundai and Kia models (same company different brand names)

I've done many kias/hyundais with factory alarms and there is always an arm/disarm in the driver kick panel in a plug going into the door.

Then why is this information not found on the wiring diagram on this site nor is it on the Audiovox website? Are they wrong? I also believe a poster previously asked about the factory disarm and was told it was only available through the factory remote. Will research the post later as I am in class at the moment.

There's lots of things the tech sheet doesn't tell you. It doesn't mean that it's not there. Use your multimeter and test!! You can arm the car by locking it with the switch and closing the door then if someone reaches in and opens it and sets off the alarm you're telling me there's no way to disarm it? Or if they arm it with their factory fob and leave the windows open then suddenly their fob battery takes a crap and they just reach in and open the door and the alarm goes off they're screwed?

Disarm wire will generally test negative when turning the key in the door to unlock. Very very simple.

Like i said every kia/hyundai with a factory alarm i have found a disarm in the kick going into the door. Sometimes the tech sheet tells you where and sometimes you actually have to test for it yourself. Either way it's there. Most times i've seen it has been a pink or a grey, sometimes both.

If the key in the door disarms, there's a wire to control it. It's that simple....

Ok I will check out the alarm today.. Sorry If I came off offensive I was just wondering why I didn't find that when I searched :) Maybe I searched for the wrong term.

-------------

Ok I just tested my car if you use the key in the door to unlock the car. The alarm goes off :(

If i Can't Install it    I Don't need it   Joe

well there must be something wrong with your vehicle that the key unlocking the vehicle from door sets off alarm.like someone mentioned before what if you lost the fob or battery died and you had to unlock it with key. you should be able to unlock and disarm with key otherwise your screwed.i would take it to the dealer and tell them this. it doesn't sound right to me

I will poke around tomorrow since it will be a few more days before the Viper gets here. Right now It has an Old school Harada installed. I inherited the car from my dad. It seemed fishy to me that there was no way to disarm the alarm. The installer that did the starter originally told him the same thing. Maybe he was just lazy. Now that there is definitive proof that there should be something that works I will test further. I didn't really want to go poking around for something that wasn't there.

Finally got the Viper and installed it yesterday. Still no joy on the factory disarm. What I'm going to try today taking apart the driver side door panel and see if the disarm wire is connected to the key cylinder. If I can't find it inside the door I am calling the dealer to see what they would do if I lost the remote. I am also going to look for the Alarm module, according to the wiring schematic for the vehicle there is only one controll wire running from the ETACS to the alarm module so its likely multiplexed some thin in there has got to disarm this alarm. If all else fails I will just unplug it or cut the key off the factory fob and keep the fob in the car in case the factory gets armed.

-------------

Took A look inside the door and all I saw at the key cylinder were 2 illumination wires.

Direct From the owners manual. You cant use the key to disarm the alarm in the door you have to turn on the ignition for 30 seconds. :x


Edit: Also I tried grounding the hood pin wire and it will still arm if you try to arm it. So I am left with either unplugging it (hopefully the door locks still work) or giving it 12volt constant at the IGN 1 input where ever that is Or lastly just not arming it on accident.

I agree with sneakycyber. I have a lot of experience with Hyundai, and just a few Kias...but they're almost always pretty much the same car anyway.

Here it is:

1. Older Hyundai: If you see an all-black keyfob, two buttons side-by-side and another button below....... with a little leather strap to hold it to the keyring, you can't do arm or disarm.

I usually sell them a one-button remote-start-only piece, as the factory remote will work just fine with the car running (as long as the installer doesn't connect anything to the car's keysense wire).

Other choices would be to install RS/keyless and live with no factory alarm....or even install an aftermarket RS/alarm combo if the customer's budget allows.

2. Newer Hyundai, with a modern-looking remote with all the buttons arranged vertically, and a chrome piece where the keyring attaches.

These cars have arm and disarm wires. Also, the factory keyless doesn't work while running no matter what you do.

In this case, I sell RS/keyless/trunk, connect the arm/disarm wires, and advise the customer to store the factory remote, and use the new one for everything.
