Help my 406 seems to have imobilized it self after I pulled out some of the fuses to check out an air bag fault.
I asked a local garage for help they are suggesting a new BSI unit at £350 which will need to be remaped.
I have no dash info the doors will lock then open straight away the car turns over but wont start
any suggestions would be appriciated car just stuck on the drive

. Put the driver’s window down, lift the bonnet and ensure all
equipment is switched off.
3. Ensure all doors are closed and remove key from the
ignition.
4. Wait for 3 minutes, disconnect the vehicle battery and wait
15 seconds.
5. Reconnect the vehicle battery, wait a further 10 seconds (do
not open doors.)
6. Switch on the side lights through the driver's window.
7. Switch on the ignition and check system’s functionality.
8. Hold lock button on key down for 10 seconds.
9.remove key open & close door test c entral locking system
10. Start the engine and complete the system’s check.
Failure to follow this procedure could result in incorrect operation of many
BSI related items.
It did take three attempts following this procedure before it worked.

dont think you will need a replacement bsi if vehicle was running before fuses removed, but you may have wiped all the data from the bsi unit. the key code will have been wiped, so the car wont start, and the bsi will have wiped all the functions your car is programmed to have, so it does not know what to display now. you will need to get your car to main dealers to re configure your bsi, code keys in etc. go from there.
