94 Jeep won't start Security system draining battery
My 94 jeep won't start and when I turn the key it makes a tinking sound. I would like some advice how I would go about disconnecting the system and still allow the truck to work. It's draining my battery, when I get it jumped it starts but it does it again. I have been told to deactivated it and activate it via my key through the drivers side door but even after that gets down it still reverts back to the orginal problem. Please someone HELP ME!!! Thank you.

Re: 94 Jeep won't start Security system draining battery
Find and pull the fuse. Even aftermarket units have a fuse somewhere.You will need a new battery after you find the problem as starting batteries do not tolerate going flat too many times. They are not designed for it.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

Try putting your key in the driver's side door, turn key to the left, then to the right and back to the left again. This should leave the door in the unlocked position. Now insert key in ignition and see if it starts. This worked for us, jeep apparently had a security system on it and we had no keyless remote that came with when we bought it.
this sounds like a low battery problem ... the horn and lights do not take much energy to turn on, but starting the engine takes a lot of power. Try jumping the Jeep with another car, or a battery jump pack (available at any auto-parts store). If the engine kicks over and starts, then leave your Jeep running in park for about 15 minutes. After 15 minutes of running, turn the Jeep off and then try to start it again with no jump -- if it starts, you had a low battery, but the issue is probably solved (running the engine recharges the battery). If, after you have had the car running for 15 minutes and turn it off, it does not start on its own, you probably need a new battery (and you should have your electrical system checked as you might have a bad alternator that is not charging your battery). Sears Auto Canter has a great piece of equipment that can test your battery, and your entire electrical system (including the alternator) in just a few minutes. I recommend that you take your Jeep to a Sears Auto Center and have it checked, whether or not the jump worked because their system can make sure that there is not a slow drain on the battery (due to a loose connection or something like that) which would cause you to have the same problem again.
I can tell you how to disable the security system, but I can't guarantee it will work again in the future... If interested, read on.
Under the rear passenger seat there is a wire harness. Look for the purple wire with the yellow tracer. Cut it and touch it to a ground point (scrape a spot down to metal somewhere nearby). This should disable the security system. If I remember correctly back to when I had the same problem with my 94 Grand, I actually crimped an electrical connector to the end of the wire and attached it to ground permanently with a screw. I had no security system, but I could drive my Jeep!
I have a 5.2L V8 Jeep Grand Cherokee and i know to reset my security system i actually have to go around to the passenger side door and lock and then unlock it again. Seems fairly odd but that's how i was told it was reset. Give it a go and lemme know!
have you tried manually unlocking the hatch to reset the security
system?? My 94 grand cherokee limited did not have a key pad to turn system on/off...i have reset it by turning the key in the rear hatch lock to the left twice...see if this works. - SmokeWrench
