Chaos719 I have a 99 WJ. I believe SKIM became standard in 2000. Haven't torn into my steering column but I did check the build sheet. I got a generic key when I bought it.

rjbruzan Dont all WJs have a skim? Is your key gray?

Chaos719 Sorry to bring this back from the dead but I just recently purchased a 99 WJ and wanted to install a SKIM unit. I read somewhere that used SKIM units have a memory of the keys used. Can someone confirm this? I see all the used SKIMs for sale on ebay but if they're locked down already how can they be reused? If they're not locked down some have keys, keyless entry remotes, ignition cylinders, even the vin from where it was pulled making it a easier install other than the visit to the dealership to activate

tcmault blue02tj,

What did you do to fix the plug issue?
11-26-2010 07:24 AM
blue02tj Very helpful as I am having to put the SKIM module back in my 02 TJ since it was smashed when the thives tried to steal my jeep. I have the FSM but your pictures really helped. They also cut the plug off that goes to the SKIM module any ideas where I can get another plug to splice into my harness? I have been looking at used harnesses off EBAY but I only realy need that lead.

blue02tj Thank you for this topic. My 02 TJ was recently a victim of car theifs. They were unable to start the jeep due to the SKIM but did manage to destroy the steering column and cut the wires to the skim module and smash it off the column. I have since replaced the steering column and only lack the SKIM module and the nessary plug that comes from the harness (they cut it off and its missing) to get my jeep back on the road. My only real challange now is finding an old harrness I can get the skim module plug from to splice into my harness.

I have the FSM but this thread along with its pictures helped out alot in seeing how its installed.

phoenixkeyguy Hello all!

I am a locksmith in the Phoenix area and I thought I would reply with my two cents here...

this is a great addition to your ride that will greatly increase the security of your vehicle.

RedRubiconLJ has done his homework on this subject.

Dealerships will charge exorbidant prices because they have you "by the balls" if you lose a key
and your ride is stuck at their shop. Its true you have to have 2 working chipped keys before you
can add the 3rd-8th keys. Keys range in prices and you don't have to just buy them at your dealership.
A locksmith in your area can provide you the nessecary keys for cheaper *lets say $25-$35 to duplicate
the cuts of your chipped key onto a not yet working chipped key.

"Be careful about locksmiths that can "program" replacement keys - what I saw in another thread
is that they are just cloning the old key, so you still won't have enough keys to program a new

True there are some locksmiths that will do this!! A reputable locksmith in your community will
have some kind of programmer tool (advanced diagnostics or TKO) that plugs into the OBDII port on your
Jeep and can ORIGIONATE keys just as the dealer would. Typically it costs around $100 a key.
They also can clear fault codes and a number of other things!! Be wary if they aren't going
out to your Jeep to 'program' the keys, they are just cloning them then.

Dealers 99% of the time they will

charge you 1 hr of shop time to add keys that you can do yourself in about 30 seconds!!

Just follow the instructions in your users manual for adding the 3rd-8th keys.

Also if you do this install and accidently plug your SKIM module in, instead of towing your Jeep to the

dealership and having to get your car fixed during business hours only; you could call a reputable

locksmith who can come out and do all the key programming and get you set up (even in the middle of

the night) and may even be cheaper after all said is done without missing work or additional trips to
the dealer!!

"I have called the 800 customer service number, talked to the service advisor,
talked to a tech, looked it up on dealer connect website and they all tell me
it can not be done if it did not come with the skim from the factory.
Trying to get a PIN is like pulling teeth..."

The reason for this is because the pin is what unlocks your vehicle and allows all the components
to work with your car's computer and a would be theif can use the pin to program a new key and
steal your ride. It is almost impossible for an individual to get them to give you a PIN # over
the phone...

The dealership has a computer program that runs your VIN and are able to pull up the PIN in
seconds. A decent locksmith will have access to these systems as well and will be able to get your
PIN in a few minutes.

If you already have 2 working ORIGIONATED keys, you can buy additional keys/key blanks from
a "cool" locksmith probably cheaper than you can find online and get them cut/duplicated so theyre
ready to add.

The key model for a 2007-2009 Jeep that is chipped is a Y164-PT (very common locksmiths will carry this key for about $20 uncut/unprogrammed)
The key type for a 1998-2006 Jeep that is chipped is a Y160-PT (very common locksmiths will carry this key for about $15 uncut/unprogrammed)

these two when programmed correctly are considered origionals to your car's computer

I hope this helps you guys!! Just if you do need a locksmith to help you make sure they know you would
like keys ORIGIONATED and not CLONED!!!!

- bond skim to ecm with pin (I don't recall if it is bond, join, program, etc. but it was fairly obvious. and its not the "replace skim module" one, its "bond new skim" or some such)
- program keys to skim from same menu
So if i order the SKIM and keys, and install myself (not hooked up until dealer has it), where do i get the pin number?

maddiver You are both correct.
I did some further digging and found the SKIM module by a different name located elsewhere on the parts list. The part number for the 2000 module is:
56009712AC - which, has now been updated to 56009712AF. My local dealer has them for 62.55 +tax. They guy in the parts department wanted to argue with me. After he made his "you can't do that" speech I said: "Hey, I'll worry about that. Are you going to sell me the part or aren't you?" He got pissy but sold me the part. Then, when I went to the service manager to get it installed he got a kick out of the fact that I was adding it. When I told him about the parts guy you'd have thought I him with a baseball bat. Apparently the parts guy has a problem telling people what they can and cannot buy for their jeeps.
Oh welllllll -

97 - 99 do not name an immobilizer module in my parts list.

Try looking at a 99 Sahara. I know my old 1999 TJ Sahara had the SKIM Immobilizer on it.
