Hi everyone,

I bought a second hand A160. I found the central lock does not work.
On the keyfob, there are two buttons, lock and unlock. When I pushed unlock button, the indicator lights just flashed twice, and I can see the left and right light indicator signs in the driver's control panel flashed twice as well. But doors were not unlocked. I can't hear any sound which normally happened when a motor drives the lock to unlock.

It's the same situation when I pushed the lock button.

I have changed the keyfob battery. no help.

Can anyone give me a hint about this please? Or, I have to send my car to garage to get fixed. thanks in advance.
