Bought used jeep. owner lost remote for security system. had to have starter tested now the security system keeps coming on and the car won't start. can it be diabled or can the remote be replace?

2008 Jeep Grand Cherokee what cause the starter to keep on turning after i take my hand of the key? not told does engine run,.. wow. and if did run was starter screaming and grinding in pain, load and nasty sounds.
my guess it did not start the engine but im only guessing.

HAVE THE SAME CAR 2010 AND FULL OEM FACTORY 7000 PAGE SERVICE MANUAL IN IT.

ONLY 3 CAUSES OF ST LINE FAILURE HERE.
DO HAVE THE KEYLESS OPTION?
as in no dash slot to hold the fack key like mine has.
i will not guess 1 cause. will do all.
1; battery is super low now. and causes BCM to go mad. ( i cant hear your starter and hearing matters for 100 points here)
2; starter bad it can in fact stick (jam) or half stick and starter sings super high rpm but not the cranks shaft at all
3 the keyswitch is bad, stuck in ST position failed.
4: starter relay is bad as in contacts inside it welded (called fused)
5: if keyless option? dash has no key slot
6: added remote start box to car? as in remote cranking and starting?

we can see the car and all options on the car. day1 , or added later.


mine has this.
but mine has no remote start.
this yours.
this plugs into dash slot and there is a real key switch there.
when turned off the starter must stop, and engine.
if the starter keeps going , see my list.
for sure charge the cars battery 100 % first and now to do testing
not told engine runs.!!!

Sounds like a stuck relay.

it a factory options, this, if not, then its aftermarket hacks.
the 2008 is first year, for OEM remote starts. IIRC
if true a hack, then find who made it and get their books.
full documentation, if not found rip it out and try something that
works and is documented. fully.
some are dangerous... here is a selection of hack systems.
NON OEM.

getting it to work right takes , picking one that is legal, and safe.
and reliable, and and installer that knows wire NUTS dont cut it.
etc.
id never do this to my primary wiring on any car.
and know how!
post the make, brand , and unit partnumber, or a photo
of the main box label.
and hope is possible.....

Hard to tell. If it is working now, they must have done something. It could have been a bad connection somewhere.. Sometimes when checking connections, problems go away. Only time will tell. Remember it is important to have both the engine and the body to have good grounds.

The security module is located in the dash behind the glove compartment. You cannot disconnect the security module without bypassing the starter wire. The system disarms by unlocking the front doors or tailgate with the key or using the remote key fob. The switches on the door latches are notorious for going bad on the grand cherokees. These switches are inside the doors attached to the lock cylinders and cost about 40 bucks at the chrysler dealership. You can also get a replacement remote fob on ebay but they are around 50 bucks and you will need the owners manual for the Jeep to program it.

do you have a remote? sometimes when you have remote unlocks and lock with the remote and try to unlock manually(with key) the security system "thinks" its being picked and will not allow the vehicle to start or run.

if problem still occurs let us know and we will gladly get you through this

A Simple Battery DRAW test w/ test light to Determine there is a Draw on Battery. With EVERYTHING OFF will determine that Something is Drawing Battery Down. Test light "Clamp on Neg" At Bat And the POKER AT CABLE, if it lights up you have a Draw
To Determine were it is, Pull Fuses out 1 by 1 Watching Light puting Fuse back in When you Pull a Fuse that turns the Test light off you found the Circuit that is Draining the Battery if it is A Circuit that Remote Starter is Connect to refer to Installer to Correct the Problem

NOTE TEST Light Connected this way and Electrical System in Tact Light WILL NOT BE LIT at ALL
Dont forget to keep doors closed during this Procedure

That's not a remote starter on your key chain, it's a keyless entry for an alarm system.

The disarm switch on the latch inside the door is most likely defective, pull the door panel and test it for proper function.

check to see if your starter has power. before trying to start, then with key on then while attempting to start
on the remote situation they are like $50 at the dealer and they program them for free
