The dealership can generally program a new transponder key based on the VIN. Most good locksmiths can reproduce the key, but would need the original to do so.
This is not for the rule abiding, uptight individual, so as far as the rest of the world goes.. if you have one key to your transponder key vehicle. Simply take the key hide it under your dash on the driver side in any fashion you feel comfortable with, but, of course, have a key cut that matches it(regular key) your computer will pick up the transponder under the dash and the $3 key will start it. Your other question will be "can people still my car now" yes, they can... will they.. NO, probably not. The reason for that is, that thieves know what they are stealing. they know your car has a transponder on it and won't even try.. they will move on to the next car. Can you bypass the transponder? NO. once again.. a thief knows this...

the plastic cover on a key with an immobilizer is softer and larger than one without. if you have no key to compare, look on the dash with the key not in the ignition. if there is a red light in the shape of a car with a key shape on it that flashes every 2 seconds or so, it has a transponder. when you put the key in the ignition the light turns off.
Your local Jeep dealer may be able to help you with that. 20,000 Jeeps is a lot of Jeeps so they may not all be delivered at the same time.
Take your VIN and proof of ownership to the dealership and they can get you a new key.

If you are speaking of a key for a recent model vehicle ( 97 model or newer ), the so-called "code" you are speaking of stands for PLASTIC TRANSPONDER. Some keys will have PHT written on the key in the same fashion.....meaning PLASTIC-HEAD TRANSPONDER. Of course, the PLASTIC (P) or PLASTIC-HEAD (PH) refers to the upper ergonomic portion of the key. The TRANSPONDER (T) stands for the programmable "chip" inside of the key, which leaves your vehicle immobilized if NOT programmed or NOT present at the time of ignition.
An aircraft transponder signals position and (usually) altitude too to ground controllers. A nonfunctional transponder can be removed from its mount with an Allen key and sent to an avionics shop for repair - or another used transponder can be purchased to replace the failed item. Repair costs can easily equal replacement cost with a used item, so this choice can be attractive Looking on eBay can be helpful.
Key has transponder that needs to be programmed. You may have to tow vehicle to dealer to do so
Your 2001 Ford Explorer uses a key that has chip in it called a transponder (as you know). This chip has a mathematical formula that is used to answer a numeric question that your car generates. If the answer is correct the car's computer allows you to start the car. (A Simple Example: what is 5 multiplied by X?) The transponder and car both know that X = 2 so the chip responds with the answer 20, and the car, knowing the answer is correct, starts. This all happens in about a tenth of a second. There is also about a billion possible answers to the cars question, so if you use the wrong key, it will give the wrong answer, and the car will not start. So, to answer your question: If the key turns in the door and the ignition that it is working mechanically, but the transponder part is broken. If the key does not turn in the lock, the mechanical part of the key (the cuts on the key or the wafers in the lock) are not working properly. Either way, a Locksmith in your area should be able to help you out.
