Fiat Key Coding Information

Coverage in FiCOM

Transponder types

Fiat uses the following types of transponders. We note that the transponder system rolling code (starting CODE2) must be pre-programmed, because they contain pre-programmed binary encryption key (the dealer key, which can only be ordered based on the VIN code).

Previously deleted keys cannot be programmed again. Diagnostics can only add keys to the system and later CODE2 (Megamos crypto + HITAG).

Body system

Body modules use following types of transponders:

Warning: key contains programmed data for a specific vehicle (the dealer key), this must be ordered from Fiat or pre-programmed by special tools from the content of EEPROM BSI.

Key coding

The function is available from menu of coding BODY COMPUTER control unit.

Login function is used to verify the PIN code from CODE card and to gain access to secure special functions (for key coding is not needed)

Coding transponders can be done by selecting the "Keys Coding" function. The procedure is as follows:

• Activate function
• Enter login code "ELECTRONIC CODE" from the CODE card
• Insert all keys one by one into ignition according to program message. After inserting all keys will appear a window asking if you want to coding another key. If you answer yes, the program will wait to insert a new key again. Otherwise, it will save the loaded keys and display information about the end of encoding.
• After you insert all keys one by one, end the coding routine.
• You will be asked if you want to save transponder keys in memory. If you confirm the saving, you will delete all the keys that were not inserted into ignition during the operation and these keys will be not possible to coding in future again.

Previously deleted keys cannot be programmed again. Diagnostics can only add keys from system CODE2 and later (Megamos crypto + HiTag).

Remote controls coding

Operation works similarly as transponders coding.

Verification of coded keys

Value of "Number of enabled keys" in measured values should be the same.

Immobilizer Code2

Warning: key contains pre-programmed data for a specific vehicle (the dealer key).

• Login
• Key coding
• Information about coded keys
• Key deletion

Immobilizer Code2 Iveco Bosch

Transponder Philips Crypto, key contains pre-programmed data for a specific vehicle (the dealer key).

Key coding is not supported at this time.

Emergency start

This procedure allows you to start the engine in a situation, when it is not possible to recognize the key or in case of failure of immobilizer control unit. Starting the engine is possible after entering the electronic code via the accelerator pedal. Proceed as follows:

• Turn the key in ignition to MAR.
• After 2 seconds, the EDC warning light starts to blink.
• Depress the accelerator pedal up to the stop and hold it depressed for 5 to 12 seconds.
• EDC warning light starts to flash more slowly.
• When the number of flashes equals to the first digit of electronic code, depress the accelerator pedal to the stop and subsequently release it (when depressing the accelerator pedal, the EDC warning light turns OFF ). Follow the same procedure for entering of remaining digits of the electronic code.
• After correct entering of the code, the EDC warning light stops flashing (otherwise repeat the procedure). Contact your authorized service always for check the system.

Immobilizer Code

First generation of CODE control unit does not have a diagnostics, keys are coded by master key. The keys doesn't contain data for a specific vehicle. It is not possible to code more than 7 keys.

Procedure of key coding

• Insert a red master key, turn on the ignition and turn it off immediately when immobilizer warning lamp goes off .
• Remove the red master key and insert another key to coding within 10 seconds
• Turn on the ignition and turn it off immediately when immobilizer warning lamp goes off
• You can repeat procedure from point 2 and code other key within 10 seconds
• When all keys are coded, end the procedure by inserting the master key and turning the ignition on and off when immobilizer warning lamp goes off.
