When doing all keys lost on a Ford Transit 2006, 2010, 2013+, when the alarm has been activated , the BCM is blocked and denies entering diagnostic session. This won’t allow programming/deleting keys and the procedure will fail.
The following few steps are the workaround to this issue:
- Select the CCC function - Central Car Configuration
- Read the config from the Master BCM module
- Find parameter “11 Alarm”- there is a value “01 Alarm” Edit it to “02 No Alarm” and write it
- Now you can enter the function to erase/program keys- the BCM is no longer blocked
- Once done, enter the CCC and enable the alarm using the original parameter
