changed the dash loom both (the one with crusie and the dash) now the car will not start the smart lock flashes 3 3 3 the really fast when the key is in the on possi!

you need to retrain the smartlock - it won't work straight off!

there should be some instructions in the tech docs section about the correct procedure to do this!

Starting a Smartlock Immobilised Falcon
The immobilised state is indicated by the Smartlock warning jewel (LED) as a rapid flash rate.
The system enters the immobilised state if Smartlock receives at least two incorrect codes when the ignition switch is turned to On.
When the car is in the immobilised state, you cannot start the engine, as the BEM has disabled both the starter motor, and the EEC-V system.
If the cause of the immobilisation is a corruption of the codes during transfer, you should be able to start the car on the second attempt.
Note : The remote keypads will still operate on an immobilised car, however an immobilised car will not display the immobilised flash with the ignition off, and will display the armed code as normal.
If the cause is an unauthorised attempt to start the car, i.e. by hot wiring, the car will remain unstartable. However to prevent a vehicle from being completely immobilised, (Eg. due to a damaged electronic lock assembly data), you can start the car by using the method below.
The following method must be used if the BEM, or the electronic module has been replaced, so as the new Codes from the electronic Ignition Switch are RE-LEARNT.

1. Turn all accessories off.
2. Turn the ignition to the On position.
The Smartlock warning Jewel (LED) will flash any error codes, then finally the immobilised code.
3. Leave the car for 30 Minutes.
4. After 30 Minutes, the BEM will attempt to relearn the electronic lock assembly data.
5. If the learning procedure is successful, the warning jewel (LED) will then stop flashing and the door locks will change state twice. You can now start the car, and operate it as normal.
6. If the learning procedure is unsuccessful, the warning jewel (LED) will stop flashing and stay on, and you can start the engine.
