Other half parked the car at the station this morning but the car refused to lock. After calling me, I locked it remotely and she jumped on the train.

I popped by an hour later to see what was going on - I’d jet washed the car yesterday. But car unlocked and locked with my key just fine.

Assumed a low battery on her key, so stood by to unlock remotely when she arrived back at the station... but it all now worked with her key too.

Local electrical interference? Random behaviour?
Or am I being (too?) paranoid and might there may have been someone blocking/interfering with the key signal?

P L405SC just arrived... still working everything out!
