2010 V70 door lock

[ChrisRS]

Noticed today the o/s rear passenger door lock on my v70 doesn't lock correctly on the remote, the pin on the door card moves a bit but not enough to lock, if I push the pin manually the door lock ok. It unlocks fine on the remote. Does this mean the actuator has had it or will a bit of grease do the trick?

Thanks, ordered a used actuator from a breakers, stripped the door the access it only to discover I've got my n/s & o/s mixed up. I've ordered the wrong one! Hopefully they'll exchange it for a small fee.
