Went to junkyward to get new rear window hatch was locked so I was just messing around and tried to unlock with my key and it opened then I went to ever other one in the yard and they all opened. Has this happened to anybody or is this a new discovery haha. It is a 1994 2 Door XJ

 

use your new found power for good my friend, and dont worry every other key in the world will work on my tauruses ignition. XD

 

its probably because your key is nice and worn down that it works in other jeeps...heres one for ya, i have two cherokees. jeep A's key works for jeep A and jeep B. but jeep B's key only works for jeep B. i never really knew the science behind it but i just figure its a jeep thing lol.

 

There are only so many different keys made so I imagine there's not a terribly small chance of you and the next XJ owner having the exact same key. I heard the last car I owned, a nissan, had less than 10 different keys.

 

The keys for the other jeeps don't fit mine but mine has fit 5/5 of other jeeps so far still looking for others to test. Not really much I would do with it though don't feel like going to jail and if they have an xj with something I want they are probably my friend haha.

 

I'm sure 96xj is right and yours is worn down. A friend of mine and I both had a 240sx and the only difference between our keys was one notch was off by about 2mm.

 

I haven't tried that...I will pretty soon for experimental reasons only of course.

I don't know if this has happened to u guys (also key related), but I can remove the key from the ignition without having to turn my XJ off, it just continues running like nothing.

 

Same thing happened in my moms old Plymoth Voyager I dont know why but it is a good conversation peace when you drive around and just take out the key haha.

 

Yup, my friends freaked out when we were driving around talking and I suddenly pulled the key out. I was holding it in front of their face and it took a while for them to figure out what was going on. I think it is hillarious, but I have no idea why it would do that...do most XJ's do that?

 

.............ill try that when I leave borders..

 

bet even if you open the doors you still cant start it tho...

 

i was talking about the ignition lol my door locks never get used

 

I can take my key out at any out when my jeep is running. Weird, but it works good for playing the radio with the drivers door open because it doesnt beep

 

my 97 zj key worksin my friends 93 dodge ram..one day i was kidding around and told im i was taking the truck and i put my key in the ignition and heard the door buzzewr...then i turned it and it worked i was so suprised..his dosent work in mine tho

 

this is actually a pretty common thing. Most car companies (Chrysler as a whole, GM as a whole, etc) only use about 10-15 different cuts for their keys, so many vehicle have the exact same key set up. A perfect example is my mom's '01 Olds Intrigue key will unlock and start my buddy's '03 Chevy Tahoe, and vice versa. My '89 Z24 would work in my sister's '93 Beretta.

The whole "pull your key out while driving" trick is pretty common too. It's from the ignition lock cylinder getting worn down from repeated use. My wife's '01 Saturn does it.
