Z is unlocking after locking it with key fob
 

Wondering if anyone experienced a car unlocking after locking it with the fob. I had the car in a body shop and when I got it back I found all sorts of stuff wrong. It even had to go back for wrong size tires. I did score some new tires and undershroud so maybe it was worth it but...This issue I'm having...They did manage to drain the battery and recharge it and they had the driver door off for paint. So maybe the battery is low? Would that cause a issue with unlocking by itself? I already had the panel off because they forgot to connect the cable to the lock latch...No way I'm letting them look at it. Just praying its not a short or pinched wire wire. Any thoughts. Can't remember voltage not running 12.5? Or 14 any thoughts? Thanks!

Voltage not running is 14, running is above 12.5.

Regarding the unlocking - I don't know...but on older BMWs, the tendency was that if your door lock on either door was jamming, it would do the locking/unlocking twice instead of just once. Not sure if it's possible Nissan has something similar.
