Question about factory alarm system

[Graewulf]

My GC came with the factory alarm system - 1995 Laredo... I want to install a remote start and replace this worthless piece of #($& infrared FOB that only works for about 5 feet.... problem being i need to bypass the factory alarm system for the remote start to work. does anyone know anything about how I would go about setting this up? is there a bypass module i can get? Every one i seem to find only works 1999 and up....

As far as I know, you cannot bypass. Alarm system is integral to vehicle. There are at least 7 fuses that involve alarm components. You can use power door lock switch to lock vehicle and key to open and this keeps alarm system passive, won't arm. The remote should work to 16 feet.

all you should have to do is use the disarm off the remote start and you should be good to go i dont think there is anything special about that factory alarm to worry about but i will double check for you tomorrow

Nope, your car is super easy to do. It does depend on if you have just a regular Cherokee, Larado, or Gr. Larado but it is all pretty simple. Now, if you have a "new" '95 to the point it is wired like a '96 then you have to do a little more but it is still real easy. Take a look. http://bulldogsecurity.com/

Well, you won't be able to know without taking some things apart and looking. I guess you could look at the build date on the driver's door to see what the actual date is. If it is dated late in '95, then it could be on the newer system.

I have a 1993 Jeep Grand Cherokee and everytime I use the lock button it sets the alarm and the alarm goes off for no reason. did you find a good way to bypass that alarm, or maybe you know where I could find a fix for my problem. Please e-mail me [email protected]

I disagree. You may be successful installing after market alarm, but does it do all factory alarm does? Just as easy fixing factory alarm.
There are 4 components that may go bad.
1. You have to have at least 1(of 3) key lock switches that work. Any one will disarm system manually. if bad @$24 apiece(www.jeep-parts-dealer.com/) under electrical/body electrical/security system components/door sense solenoid.
2. Alarm board in dome panel(infrared reciever) @$120 same url link
3. Security alarm module(SAM) Lift glovebox bottom, you'll see relay center. SAM module is to the left of relay center. If you have autosense headlight, that module will be between relay box and SAM, otherwise,you'll just see a connector. @$12
4. In that relay center the top left relay is ATC relay. Controls inputs from the PCM. @$8. This is the one you hear "buzz" when you pull alarm fuses out.
PCM's rarely go bad. Usually sensor,wire,fuse,etc
Hope this helps all

does anyone knows how to avoid the alarm system to kick on when using the lock button to lock my doors, cause my POS remote is broke and most of the times opening with my key does not work or need to try like 100's of times.

Are you serious with this reply? Just about every OEM alarm is barely a good paperweight. For the life of me, I never understand why they seem to malfunction so easy. I mean, most only have door intrusion sensor. So, only if you open a door, trunk, and sometimes hood do they ever go off. Thieves know this so they just break a window and hop in. As long as they never open a door, they can have fun.

The only thing I can think of is to ground out the disarm wire constantly. If the system sees that grounded, it won't arm. Most Cherokee's (93-98?) use a PURPLE/YELLOW wire in the driver's kick panel or door harness. You could even take off the door panel and find it inside. Now, if you have a newer Jeep, there's a little more to it.

Ponchouty, they can hop in all they want. They will NEVER get the vehicle started no matter what they do, unless, like you said, they pull door panel all the way off up to the key lock cylinder and pull the purple/yellow wire off and jump the door sensor switch. Wonder what safeguards aftermarket has. I really don't know. Maybe it's better. Would like to know how?

Actually, all I need to use is a cordless screwdriver with a lag bolt in it. Go up to the lock on the driver's door and ram it in. Eventually, it will bust it and unlock the door. Once it does that, it disarms the vehicle. The most popular alarm from DEI I sell comes with a 2-way remote and battery backup. So, no matter what they do, you get notified. Plus there's that GPS tracking deal the unit has too.

Almost any aftermarket alarm is better than most any OEM alarm especially Chrysler ones. I should know, I deal with them on almost a daily basis. Granted sometimes the OEM alarm is better than none at all but not in this case.

well, color me an idiot! I'm sure the sight and sound of someone taking a drill to the door would never be observed or set off the alarm. Actually, someone tried to pry my door loose from the post. Never got in and alarm ran em off in motel parking lot

Actually it probably would never be seen or heard. It is so quick to do. I mean, you are not drilling for 10min.. Also, NO JEEP ALARM HAS ANY SORT OF IMPACT OR SHOCK SENSOR. Besides, the idiot that went for your car didn't try to disarm it first.

I have been in the car biz for many, many years. I have been working with insurance companies fixing all kinds of different things on recovered vehicles. The drill to the locks is the most common thing to do. Sometimes they will pop the whole lock mechanism with a screwdriver. As long as they ground that disarm wire, they are home free. Does this work 100%? I doubt it. Either way, I am just stating what I see. Is any alarm 100%? No. If they want it bad enough, they'll get it. My point is that I have never seen a factory alarm that's really worth it. I mean, in every Chrerokee, it's located in the same exact spot and takes very little to disarm it.
