Intermittent door unlocking problem

[StGeorge]

Hi all,

Our 18 plate NX seems to have developed an intermittent issue whereby the front passenger door won't always lock/unlock with the rest when using the remote keyfob.

I've seen a few suggestions online about the actuators being temperamental, but also wondered if there was some kind of reset of the central locking or something of that ilk that might be worthwhile trying?

It's due its service in a couple of months so could get it looked at then, but it's just a pain in the butt it not unlocking reliably.

Thanks
