In addition, since there are no buttons on a clonable key, it cannot unlock the doors or trunk, or open the sliding doors or tailgate.Ī clonable key blank is more expensive than a “fixed” value transponder equipped key blank. For example, some vehicle keys will adjust the seat, mirrors and the radio stations. Approximately 85 percent of vehicle’s keys can be cloned.Ī clonable key cannot capture the unique programming features of a specialized transponder equipped key/fob that personalizes the vehicle. Some of the not so good things having to do with clonable transponders are the limitations and costs. When the transponder is read, pre-cloned keys display their cloned value and transponder type. To determine the identification of a clonable key, use a transponder detector or a cloning machine with readout display. The value will change when it is cloned using another compatible transponder-equipped key. One reason for pre-cloning a clonable transponder is to prevent damage to a vehicle’s computer system when a no value clonable key is programmed to the vehicle instead of cloned.Ī pre-cloned transponder is known as a rewritable transponder. The manufacturer usually determines this. Others can be cloned a limited number of times.Ĭlonable keys can have a transponder with a pre-cloned value or no value. Most of the generic “TP5” type transponders can be cloned over and over again. There are different types and styles of clonable transponders. This is because the transponders used by the different providers are not all identical. Important: No standalone cloning machine can clone every aftermarket clonable key. Some produce their own programming devices and cloning machines others produce programming devices and cloning machines, but do not manufacture key blanks. Those with the battery equipped circuit boards receive power from their internal battery.Ī number of aftermarket key blank manufacturers sell programmable and clonable key blanks. style transponders or those with the battery less circuit board receive power from the vehicle’s antenna ring surrounding the ignition lock. Battery replacement times are determined by the manufacturer. The circuit board style is further divided by those that have a battery and those that are battery less. Depending upon the manufacturer and model, the head can be a separate component or attached to the blade. The circuit board type is larger and incorporates a generic style head. This type of transponder can only be used in a key blank that has accommodations for installing these types of transponders. style transponder can be sold separate from the key blank. M.) type chips are ceramic or a glass ampoule, and can come molded into the key blank head. There are different types of transponders designed for cloning keys. The Philips Crypto transponder-based engine immobilizer systems are used in many of the later model vehicles. However, for Philips Crypto (#46) transponders, vehicle access is required. In addition, vehicle PIN codes are not needed to clone a key.įor most vehicles, there is no need to go to the vehicle. Cloning a clonable key does not affect any of the programmed keys.Ĭloning saves time there is no limit to the number of cloned keys and if the programmed key (master or valet) operates the vehicle, the cloned key should have no problems operating the vehicle. Since a cloned key is a duplicate of an already programmed key, there is no limit on the number of cloned keys that can be used to operate a vehicle. This number determines how many transponder keys can be programmed.
Sometimes the shape of the head can be used to identify the type of transponder.Ī limited number of transponder-equipped keys can be programmed to a vehicle. If the transponder is molded into the plastic head of the key blank, the part number can be used to identify the type of transponder. Whether a transponder has a fixed value or is clonable cannot be determined visually. Cloning can only take place when using a clonable transponder. The second type is the clonable transponder, designed to have a new value duplicated onto the chip using an existing compatible transponder. The terminology “fixed” incorporates both Fixed and Encrypted Transponders. “Fixed” value transponders are designed for on-board programming or device programming when connected to the diagnostic port pf the vehicle. There are two basic types of transponders.
