Central locking odd behaviour after battery change

Technical Area Electrics & ICE

  1. My model of MX-5 is: __ 1999 NB 1.8
  2. I’m based near: __Bolton
  3. I’m looking for technical help or recommendations on: __

I’ve replaced the flat battery on my NB today, and have since noticed the central locking auto locking the passenger door then trying to lock it again. Anyone any ideas why? It does this even when the ignition is off

Anyone able to assist? I read somewhere that the auto-lock for the passenger door is actually triggered in the drivers door, is this correct?

Assuming you have factory fitted power door locks, then yes. The passenger door is triggered off the drivers door lock mechanism.

Yeah, it’s all done from the original key. I’ll take the door card off this week and see if I can figure out what’s going on.

Thanks!
