Hi I Know Your Probably Gonna Tell Me My Key Is Faulty But I Have Even Had A New One.
The Problem I Got Is, I GOT A LAGUNA 2 The Car Opens On The Key CARD But Wont Lock On The Key CARD , The Centre Dash Button Or When I Drive It So It Cant Be The Key. Also The Child Lock Button On The Door Wont Activate.
The Dealer Told Me It Was The Key And I Forked Out £125 For A New One And Guess What It Dont Work Either......
I Can Tell When The Keys Break Cos You Get A Rattle On The Key And The Button Goes Soft Because It Falls Off Inside.
The cabin computer (the
) handles the lock / unlock function.
Has your dealer check the fault codes on the
? There is a specifc relay there that handles the lock signal that could be faulty. This is part of the passenger compartment relay box. Can you hear this relay click when you operate the lock button in the car?
There is a command that can be sent via the diagnostics tool to lock the car. (command AC006)
Open doors or an airbag fault can also prevent locking. These will be detected by a diagnostics check.
Sounds like it's either the relay or the
. It could also be that a fault on the wiring to the locks (short or disconnect).
