I've not been on here for a while, mainly due to the 406 behaving itself but today after disconnecting the battery for an alternator swap I now have the immobiliser fault on the display.
All the usual tricks tried with the BSI reset etc but still showing the fault. I thought I'd left the car long enough before disconnecting the battery but obviously not
Could anyone tell me if an unlocked ECU would be a straight cure for this problem or am I looking at the BSI to be re-coded to the key etc.
I have no PP2000 and wondered if there was anyone in the Hinckley/Leicester area that could do this for me, I'd gladly pay them for their time and make lots of tea if so
A really big thank you to dirtydirtydiesel for helping me out with this, it's reassuring to know there's some great people out there, enthusiastic too!
The dogs will be up the fields again tomorrow now Doris is back on the road. Thanks ddd

Nic! How did you manage to solve this issue? By fitting a new transponder antenna?
Hi Frog, the antenna was okay although I have got one coming to keep as a future spare. I had disconnected the battery too soon after switching the ignition off (for an alternator change) and lost the key code. Dirtydirtydiesel kindly made the round trip to re-code the keys to the BSI for me so am really grateful to him.

Wow, he came to your place and fixed the BSI? Cool! How did he re-code the keys to the BSI? Can that be done "simply" using PP2000? Or does it require unsoldering and reprogramming the BSI EEPROM chip?

Yep it was really good of him to help me out Frog, it was done using PP2000. I am not very techy but am on the lookout for a good used PP2000 as I'm intending to keep the car for a long time and need to learn this stuff.

Hi frog,
How are you? Keeping well I hope.
I still haven't got to the bottom of the airbag issue (but to be fair I haven't tried for over a year )
okehdokeh's problem was very straightforward,
he had just disconnected the battery before the bsi had gone to sleep,
so I needed to input the four digit security key code via pp2000.
