New Avensis Owner - 2 Questions

[FlabbyPanda]

Hi All,

just bought an ex taxi 2011 Avensis for little money and I'm very happy with it but there I've 2 issues.

1. The first problem is the central locking, the unlock button on the remote or on the drivers door does nothing, unlocking with the key only opens the drivers door. I found other posts about this and it seems to be the door lock actuator. My question is do I need to replace all 4 or just the drivers ones?

2. After nearly 300,000km the manual gear stick feels sloppy and engaging 1st take a bit of shoving to get it engaged, once moving everything is fine and the clutch is OK too, would replacing the shifter mechanism resolve this or is it more serious?

Thanks, Brian

1st gear issue turned out to be the gear linkage bushing, I used a shim to correct the opening size until a replacement comes which sorted it. The shifter mechanism has signs of wear so I'll get another from a breakers too. 

I replaced the drivers side door actuator but no joy with the central locking. I think its the relay behind the glove box as I can hear it clicking when I press the unlock button.
