Operation CHARM: Car repair manuals for everyone.

Procedure

When an owner loses an Azera immobilizer key, the customer has two options to replace the lost key. Both options require that the customer bring the vehicle and any remaining keys to an authorized Hyundai dealer.

Option # 1

The customer can use any remaining key originally supplied with the vehicle to drive to an authorized Hyundai dealer and request that a new key or key set be cut and programmed. It is important that the customer bring any remaining keys with them to the dealership. Any key that is not programmed (or re-programmed in the case of originally supplied keys) in the same operation will no longer start the vehicle.

Option # 2

The customer can have the vehicle towed to an authorized Hyundai dealer and request that a new key or key set be cut and programmed. Again, it is important that the customer bring any remaining keys with them to the dealership. Any key that is not programmed (or re-programmed) in the same operation will be unable to start the vehicle.

1. If the Hyundai dealer does NOT have a Barnes Distribution BD Laser, they MUST call the Hyundai Motor America Parts Call Center at 1-800-545-4515 and make a request (order) for Azera immobilizer keys to be cut.

NOTE:
Azera immobilizer key blanks can be ordered either in singles (i.e. 1- master) or complete key sets (i.e. 2-master keys and 1-sub or valet key). However, HMA Parts Distribution Centers will only pre-cut complete key sets upon request. They will NOT cut single master keys.

2. The Hyundai dealer MUST provide the following information to the HMA Parts Call Center.

^ VIN

^ Key Code

^ Dealer Code

^ Dealer Address (exact shipping address)

^ Dealer Contact (exact name of who the key should be delivered to)

^ Contact Phone Number and Extension

3. The HMA PDC will expedite the shipping of the key(s) to the dealership address as provided in step 2.

4. Once the dealership has taken delivery of the key(s), the key(s) must be programmed to the vehicle using a Hi-Scan Pro tool.

NOTE:
The Azera is equipped with immobilizer anti-theft technology that will not allow the newly cut keys to start the vehicle unless they have been first programmed to the vehicle.





AZERA KEY PART NUMBER INFORMATION

2. - IMMOBILIZER

TECHNOLOGY

The Azera is equipped with immobilizer anti-theft technology. This section of the bulletin provides a brief description of the technology as well as instructions on teaching (i.e., programming) replacement or existing immobilizer keys to match the vehicle using the Hi-Scan Pro tool.

The immobilizer system is an electronic anti-theft device that prevents the vehicle from being started unless a specific pre-programmed key is used (up to 4 programmed keys per vehicle). Each of these keys contain a low-power RFID transponder in the head that holds an encrypted code. When the vehicle's ignition switch is turned to the "ON" position, the coil antenna in the ignition switch must receive the correct signal from the transponder in the key or the engine will not start (crank-no start). This system prevents theft where the ignition switch is hot-wired or even where a copy of the vehicle key has been obtained (without first programming the key with the vehicle's specific code).

TRANSPONDER





When the key is placed in the ignition switch and turned to the "ON" position, the coil antenna inside the ignition switch energizes the coil inside the key head. This, in turn, increases the voltage in the transponder circuit and charges the capacitor. When charged to its maximum capacity, the capacitor discharges and provides enough power for the transponder to send its coded data as an RF signal.

COIL ANTENNA /SMARTRA UNIT





When the coil antenna receives the RF signal from the transponder, it forwards the data to the immobilizer unit (SMARIRA). The immobilizer unit then compares the received coded signal to the vehicle's own unique code. If the two match, the immobilizer unit gives authorization to the PCM (ECM) to start the vehicle. If the coded signal does not match, authorization is not given to the PCM and the vehicle will not start. The data from each of the transponders that are valid for the vehicle, up to 4 per vehicle, are stored in the PCM (ECM).

HIGHLIGHTS OF THE SMARTRA SYSTEM:

^ The SMARTRA system consists of a transponder located in the ignition key, an antenna coil, a SMARTRA unit, an indicator light, and the PCM (ECM).

^ The immobilizer system only effects the vehicle starting routine. It has no effect on how the vehicle operates once started.

^ The SMARTRA communicates with the PCM (ECM) through a dedicated communications line. Since the vehicle engine management system is able to control engine mobilization, it is the most suitable unit to control the SMARTRA.

^ When the key is inserted into the ignition switch and turned to the "ON" position, the antenna coil sends power to the transponder in the ignition key. The transponder then sends a coded signal back through the SMARTRA unit to the PCM (ECM).

^ If the proper key has been used, the PCM (ECM) will energize the fuel supply system and allow the vehicle to start. The immobilizer indicator light in the cluster will simultaneously come on for more than five seconds, indicating that the SMARTRA unit has recognized the code sent by the transponder.

^ If the wrong key has been used and the code was not received or recognized by the PCM (ECM) the indicator light will continue blinking for about five seconds until the ignition switch is turned OFF.

^ If it is necessary to rewrite the PCM (ECM) to learn a new key, the dealer will need the customer's vehicle, all of the customer's existing keys, and the Hi-Scan Pro tool equipped with an immobilizer program card. Any key that is not learned, or re-learned, during the rewriting process will no longer start the engine. Again, it is important that all of the customer's remaining keys as well as the new key(s) be present during the rewriting process.

^ The immobilizer system can store up to four key codes.

^ Transponder keys come in two varieties, "M" (master) and "S" (sub or valet). The "S" keys operate in the same way as the "M" keys but do not allow access to the glovebox or trunk.

IMMOBILIZER PROGRAMMING - IMPORTANT INFORMATION:

^ Any new key or key set that has been cut for the vehicle must first be programmed using the following procedure(s) before the vehicle can be started with the new key(s).

^ Key teaching (programming) must be done after replacing a PCM (ECM) or when providing additional keys to the vehicle owner.

^ The procedure starts with a PCM (ECM) request for vehicle specific data from the operator (i.e. 6-digit PIN code). A "new" PCM (ECM) stores the vehicle specific data and the key teaching process can begin. An existing, or "learnt", PCM (ECM) compares the data entered by the operator with the vehicle specific stored data. If the data is correct, the key teaching process can begin.

^ If incorrect vehicle specific data is sent to the PCM (ECM) three times, the PCM (ECM) will reject requests for key teaching for one hour. This time cannot be reduced by disconnecting the battery or any other manipulation. After reconnecting the battery, the timer starts again for the one-hour period.

^ Transponder key teaching is performed with the key in the ignition in the "ON" position and additional operator commands. The PCM (ECM) stores the relevant data in it's own EEPROM and in each respective transponder.

^ If the key is already known to the PCM (ECM) from a previous teaching, the authentication will be accepted and the EEPROM data is updated.

^ Attempting to program a key which has already been programmed during the same teaching cycle will be rejected by the PCM (ECM) and a message will be sent to the operator through the Hi-Scan Pro tool.

^ PCM (ECM) rejects invalid keys that are presented for teaching. A message is sent to the tester. The key can be invalid due to faults in the transponder or other reasons, which result from unsuccessful programming of data. If the PCM (ECM) detects different authenticators of a transponder and an PCM (ECM), the key is considered to be invalid.

^ If an error occurs during the Immobilizer programming routine, the PCM (ECM) status remains unchanged and a specific fault code is stored. If the PCM (ECM) status and the key status do not match while attempting key teaching, the procedure will be stopped and a specific fault code will be stored in the PCM (ECM).

^ The maximum number of keys you can program to a vehicle is 4.

^ When programming an immobilizer key to the vehicle, no other immobilizer key (or transponder device) can be near the ignition switch. If the keys are on a key ring, remove each key and program separately.

^ The presence of multiple immobilizer keys or any other transponder device during programming can cause transmission or read errors that will cause faults.
