2000 jeep grand cherokee with xk531 box

Hello all,

I have a 2000 Grand Cherokee with a Viper 791xv alarm in it. Now.. the alarm part works.. except when i tried installing the Directed XK531:JDL module that works all the doors and factory alarm. Now I've installed the module according to the wiring diagram that came in the bag but I'm having a few issues with it.

First being... it calls for having 2 keys to program it is it possible to do so with only 1 key? If not still, can anyone give me a bit of clarity on the instructions?

Secondly.. the module Pin-1 (brown) wants an wire that is ground when running the remote starts. I've attached the factory alarm disarm wire from my alarm to it. after doing so, when pressing the unlock button on my remote it locks the doors. also, when i press the lock button it does nothing. (neither lock nor unlock the doors).


can anyone help me?

edit: Also, the module will not let me go into programming mode. (like to edit to be able to do the spiffy window roll-up and such)


is there a way to reset everything on it? or do i have to take it in and get it flashed?

*sorry couldn't find the edit button to my previous post.

yess....u do need two keys to program.....second.... make sure u have the lock/unlock outputs from the alarm connected to the inputs on the module

there can be only one.......

if u have a grey key you will need 2 valid keys 2 program - if you have a black key you do not need to program the key bypass
you do not need the alarm disarm wire - it will disarm the truck w/start and unlock automatically with the gwr and unlock wires

The Viper's "status" output is ground-when-running. The "factory disarm" outputs only a momentary pulse, and should not be used.

Yes, you do need two good keys to program the remote start bypass.

The viper should have a blue wire in a 4 pin connector on the relay pack. That will be the ground while running to brown wire on xk531. The purple wire is data which sounds like you have hooked into your odbII pin #2. The transponder will need to be programmed to the vehicle with 2 valid keys.
I have made a special relay box to power up ignition and fire the ground while running input to make programming easier for me on cars such as dodge, chrysler or when installing Audiovox remote starters.
To enter program mode you insert first valid key and turn to run or ignition position. Wait for the anti-theft light to go out and take that key out and insert second key. Do this within 5 seconds and turn to ignition or the run position and wait for light to go off. Leave ignition on and wait to hear a chime and then it will be in programming mode. Take the second key out of key cylinder. Then fire ignition within 5 seconds while holding the xk531 in front of the key cylinder and wait for the anti-theft symbol to stop flashing and go off (this can take up to 20 seconds or so). Shut ignition off and it should be programmed to the vehicle. Run the wires from module to around key cylinder and fasten in place with a cable tie or some good electrical tape (3m 33+). Hook up ground while running or also referred to as status output by DEI and then with all other connections make test for start. Make sure proper engine detection is being used such as tach or tachless. It should start up after this is done.
Factory disarm is not needed with xk531, the module will interface and arm on lock and disarm on unlock.

I also would advise not mess with program options. I did one the other day at a dealership 30 minutes away trying to get the driver door priority to work and it went into a lock out mode. In other words, it froze up on me. I had to drive back to my shop and have it reflashed to reset it and drive back out to the dealership to finish the install hoping it was going to work. It did thank god or I would have had to wrap and bury a key for that part of the install and change out the module to a xk03 flashed to the JDL format.

The wire I'm test'n isn't doin' what it's supposed to be doin'... I am so glad I printed that tech sheet, with the wrong info.
Do it right the first time... or I might have to fix it for ya

That is very helpfull thanks! I'm going to try and mess around with it again tonight.
