You're going to have to essentially reinstall the system enough to figure out what's causing the no start issue. Is it a no power at all issue, a no crank issue, or a cranks but won't start problem.?

Alarms can completely cut power off to the key, cut power to the starter, or cut power to the ignition. You need to figure out what this system did. Maybe you can Google it and find out how it works or take it to a car alarm shop and see if they can tell you.

Most likely what has happened is when you removed the alarm you left some wires or removed some wires that ran power through the alarm box and then to whatever it was cutting power off to. Usually the main power to that flows to the key.

Good Luck!

The door security has nothing to do with the jeep no starting. Check your electrical leads and also terminal leads that run to the battery. If you can, get your battery and your alternator tested to see if theyre any good. If your dash indicates the following while driving;" Transmission Overheat", then, with the engine running, check your transmission fluid level. If the transmission dipstick indaictes that the amount of fluid is low add maybe a quart to it. if you do this again and you find thats its doing the same thing, then there might be a couple of things wrong;

- 1. You may have a leak somewhere. Check your lines and check around the transmission pan. If you find a leak around the pan, than that means that you need a transmission filter kit. This includes a pan gasket and filter.

- 2. If you lift the hood and look over to the left (standing at the front of the car) and find the reserve tank to have a dark color liquid in there, open the top and see what color it is. If it smells and looks like Transmission fluid, then that means you have a busted radiatior. If you open the radiatior cap and look down into it and see the that the color of the fluid is a pepto bismal- looking color, then its deffinatley time for a radiator replacement and flushing of old fluid out of the system.

-3. Transmission is burning up gears and needs to be replaced. i dont know what jeep was thinking when they put a three speed transmission in a car of that size that idles high beacuse of the gears, when it should be a five speed that idles lower being thats a bigger size car.

-4. Check your fuel lines and your fuel filter.

-5. The sensor that sends a signal to the number one cylinder to fire may have gone bad and needs to be replaced.

Ground the purple and yellow wire under the dash on the passenger side. This should fix your security issues.

If it's the factory security system that honks the horn and flashes the headlights, you can shut it off by turning the key in the door cylinders or in the rear tailgate key cylinder. If it's an aftermarket alarm, look for a small silver switch under the dash and usually turning the ignition on and flipping that switch will permanently put the alarm into valet mode. Good luck.

This sounds like a bad chip in the key, try a spare key, if it starts with spare key then key is bad, if it doesnt start then you will need reprograming

1997 jeep grand cherokee laredo my dash lights went out and the jeep wont start what do i do HELP


You have gotten two problems. First your Vehicle Theft Security System (ignition inhibit feature) has been activated. To disarm it just enter the key and rotate either door or liftgate. If this does not work, locate under in the hinge of the driver door module a violet wire with a brown tracer, put a jumper between that line and ground. That single action should allow you to start the engine. Now, the second problem is dash lights. With the ignition off, you turn the headlamp switch to the right and the dash panel should light. If it doesn't you need to start looking a the basics, that is, fuses/breakers, voltage, ground, the switch itself.
