What is the method to deactivate the Mondeo's passive anti-theft system?

Methods to deactivate the Mondeo's passive anti-theft system: 1. Leave the key in the ignition switch for half an hour: For vehicles equipped with the second-generation electronic anti-theft system, use the original key to turn the ignition switch to the 'on' position and keep it there for 0.5 to 1 hour. The essence of this process is to allow the anti-theft control module and the engine control unit to re-recognize the key. During this waiting period, do not turn off the ignition switch or start the engine. 2. Use a password decoder to retrieve the password: The anti-theft password of the engine control unit matches the password of the anti-theft control module chip. Therefore, the chip of the engine control unit can be removed, and a password decoding device can be used to read its password. Then, following the procedure for replacing the combination instrument, input the engine control unit's password into the anti-theft control module. After this, start the engine, and the locked engine should generally start successfully.
