You can buy a new key for a Jeep Cherokee either from a place that has the ability to copy a key--such a local hardware store--or from a Jeep dealership. You can buy a key fob anywhere, as long as the fob is specific to your Cherokee's year and model; however, the programming can only be done at the dealership. If you are replacing only the key and not the key fob, you will not have access to the power locks (if equipped), but will still be able to lock and unlock the Jeep and turn it on and off.
If you only need to obtain a copy of the key you already have for your Jeep Cherokee, go to a local hardware store, locksmith shop or to a dealership. You must have the key with you, so that it can be copied. Often, you can pick out different styles, and you will have to wait while the store cuts the key. This is a quick and easy process. You do not need identification to have a copy made.
Gather your personal information to prove that you are the owner of the Jeep Cherokee--you will have to go to the dealership to have your new key made. Personal information includes a title or registration stating that you are the owner of the vehicle, as well as a driver's license or other valid form of identification. You may not do this over the phone; you must go to the dealership in person.
Go to the dealership during the business hours and visit the service department. You will be asked to provide your information, so that a key can be made for your vehicle. The dealership may be able to make the key while you wait. In some cases, the dealer may have to order your key.
If the dealership has to order your key and you will have to wait for it, call around to other local dealerships to see if they have your type key in stock. Dealerships stock differently, so you may be able to get your key the same day.
To obtain another key fob, you may purchase it anywhere, just as long as it is specific to your Cherokee's year and model. Key fobs can be reprogrammed, as long as they are not part of the key itself. Ask the dealership if they have an extra key fob lying around. You may be able to get it free.
Get your key fob reprogrammed. A technician or other member of the service department must program your new key fob by accessing the Cherokee's computer with an electronic device. This is a relatively quick process. Expect to pay labour costs for this procedure.
After you new key is cut or duplicated, do not leave until you have tried the key in the door locks and in the ignition. If there is any difficulty with using it, get it corrected.
Only the registered owner with proper identification can have a key made at the dealership. You may not call ahead, as you will have to provide documentation before the key is cut. If replacing a key fob, you must bring your vehicle to the dealership where the key fob is being programmed.
