Hi Guys

So my BA Falcon Wagon has 2 issues that I need help with

1. When unlocking with the key, it no longer unlocks but can get stuck in the unlock position.

A- maybe try some graphite powder in door lock?

2. the only key fob that we had working(other flat battery) died suddenly about a week ago. I replaced the battery and have tried syncing it with the car and I can't get it to sync.

A- i take you don't know how to program key fobs? - turn key to auxiliary [pretty sure its aux not ign? ] within in 5 seconds [approx] hit heated rear window switch 3 times [whats now my yellow peril {AU wagon} took me a 'few' goes to get it into learning mode], when the doors lock/unlock you then need to operate the remotes that you have. do this one remote at a time. if accepted the door locks will cycle for each key fog ... when finished turn off car. did have a piece of paper telling me what to do & this is what's done for the fords here

Today I serviced the master actuator changing the worm drive, springs and the motor.

The doors lock/unlock using the center console and can unlock by pulling any of the other doors.
I really need to get this fixed as I can't have my missus going to the shops and having to climb through the car to unlock with 2 kids and the shopping.

Thanks in advance

1. I actually believe its a problem with the mechanism the link from the lock is attached to

2. I do know how to put it into that mode and no it doesn't work
