How was your clone key made?
If you use two keys to program a third key that third key isn't a clone. It's just another programmed key. It's the next one in your series of ten that function with your ignition immobilizer.
Each immobilizer recognizes a transponder ID series of ten. So you can start with two original keys (that have different IDs within the series of ten) and from there make more copies until the series of ten is complete.
The two keys used to program the next key have to be different ID numbers within the series.
A clone is a key that has the exact same ID as the one it is cloned from. Two identical keys (clones) can't program a third key because the computer sees them as only one key. It requires two separate keys to complete the programming of the third key.
That's why you need two keys to do the programming yourself. The computer reads them as different members of the series of ten.

do a "transponder key" search on Ebay and you can get blanks without remotes for $10 and with remotes for $42 That is what I did. Took them to the local ACE and had them cut then programed them myself with the included instrutctions. You do need two good chipped keys to do it yourself tho.

If you took one key to your locksmith, he used it to program a second key, if you cannot program a third using those two then we can guess the second key is, in fact, a clone identical in all aspects to the first key.
If you can program a third key it leaves open the possibility that your locksmith has skill/equipment to make further member of the series of ten possible. (Or made a clone and my entire theory is incorrect!)

It depends what your looking for, I have two factory keys with remotes, my primary concern is getting locked out with the hardtop on and the keys in the Jeep
a locksmith made me a plain steel key that is good enough to open the doors/tailgate etc. for $1
with wranglers it's a pretty easy fix to get a rare earth magnet and stick a spare steel key under the hood.
rare earth magnets are at least 10x stronger than regular magnets, a regular magnet can become dislodged if you go off-road

[QUOTE=jk_sea;3815835]That would be insurance fraud.
I keep one in a safe place don't leave it floating so I shouldn't have a problem anyway

I have a related question. I kept the tag that came with the keys (I assume that's the transponder number) in a safe place. However, I have other ones in the same spot. :/
Can anyone tell me what the format of the code is? For instance one of my tags is metal about 1 inch x 0.25 inch with a five digit number.

The reason it costs so much, I believe, is the dealer is reprogramming the system so the lost key(s) won't work anymore. They set it up to work ONLY with the keys they have in hand then you can program more later (so bring all the keys you have with you). Someone may have a key that will open your doors and turn your ignition cylinder, but they won't be able to start and steal your Jeep.
