central locking help

[samuria]

I bought a saxo vtr last week and the central lock worked of the near side and the boot tried but nothing on the drivers side. The garage had it back and fitted a new unit in the drivers side and fitted a new antenta. Now none of the central locking works its doesnt even try. The guy messed with it and if you put power on the boot lock it worked all the units. So the units must be ok but they have had it 2 days and cant get it to work.

Is the central unit in the roof near the aerial as it worked before he messed in the roof and put the drivers side in it must be one of those 2 places were the problem is. The car is fitted with a AOlin alarm if thats anything to do with it. The boot wont unlock with a key as it looks as if there is a broken key in the lock but you cant see it just that you cant push the key in very far.


How do you get a broken key out and could that stop the locking?
