2000 Jeep Cherokee Classic 4.0L (S) 4-spd (AW4)

On my sons car had to replace the battery and now the alarm is going off opening the car. He has lost the original remote. Can the alarm be cleared without getting a new remote. 

I have disconnected the horn but the hazards are still flashing away.

If i do get a new remote can we program or does it need to go to a dealer or locksmith

Try unlocking the drivers door, passenger door or the hatch with the key. If the door lock switches aren't pooched this should get it to shut up.

As long as the door switches are still functioning, close the door, insert key and turn it to the lock position twice (do not unlock while doing this) This will reset and arm the alarm. The turn the key twice to unlock, pause and then open the door. If the switches mentioned above are working, the alarm should be disarmed and all will be well.

The drivers door is the only one with a key lock so cant try the key any where else.

Hey David, how sure are you that it's a factory alarm and not something aftermarket. It's been a while but I don't remember those Jeeps having factory alarms. If it's aftermarket, I'll bet I can help. Let us know, thanks.

Just to be clear. This is a Cherokee or Grand Cherokee? The Cherokee did not have a option for a factory alarm.

The Cherokee does indeed, have CTD, which is what is going on here. Chrysler called it VTSS on other models. Those who state it can be disarmed with the switches on the doors are correct. It can also be done by grounding the wire at the alarm module if it has the older style of theft alarm. the horn and lights ‘flashing’ IS the factory set-up, not an AM device. Almost all AM systems (Ugh, what…

Yes it is a Grand Cherokee. What wire do i ground at the security module. Or can i access the door switch wire in the door. The door was replaced so it may have a faulty door lock switch in the replacment door. If I am to disconnect the alarm module i assume that would also stop it and the end result would be no alarm. It there anything else going thru that module.

The door locks are specific to security vehicles. They have an added sensor incorporated on the end of the lock cylinder. It is very easy to break as it is plastic. It then plugs into the door harness. If the new door doesn't have that, the key method won't work. Using a factory remote will cancel out the alarm. You can buy them used on ebay for $10+. Some salvage yards sell used ones too…

I couldn't tell you. Each scanner has it's own capabilities. Give it a try and see. One other key thing is you have to have the 4 digit PIN for the car. Some units can pull the PIN from the car. Otherwise, it's a trip to Dodge. It is supposed to be free of charge. You will have to prove ownership before they give it to you. If you have a factory security system, there will be a red led light…

Not likely. Drive Pro was not really engineered for older legacy vehicles. DRB III is your best bet.

Light green/orange at the driver door lock switch in the door. It is negative trigger thru a 463 ohm resistor.

I had 98 grand cherokee factory alarm once that gave me a lot of trouble. Door lock switch was not fuctional…. I grounded out the purple wire going into door to disable alarm, and then it would start.

Had this happen on a 2002 Ram. Pulled the battery to start another car. Reinstalled it and alarm was going off. Tried the key in the door thing multiple times, nothing. Stranded out in the middle of nowhere. Won't start either because the alarm is activated. Had been running fine for months. Forgot the exact fix but I think I didnt have the secondary wire tightened to the positive cable. That…

most likely after market. you will find the brain under the driver side. Just unplug the harness and you should not have anymore issues. The starter interrup is usually a normally closed relay no need to remove it

i do not recall a jeep Cherokee with oem alarm. Grand Cherokee yes. Ps if it is an oem system the head lights should be flashing during tampering mode.

You may not recall it, but since I owned one for many years, and then gave it to my daughter who had it for years more (just got rid of it two years ago), it had OEM alarm and remote.
