Mine is a DE and you can change the locking. Not sure about JDMs.
It took me a few goes with holding down the two buttons before it re-set the locking procedure. Hold for 10 secs then.
Some "stupid MOT tester failed the car "because he was unable to open the passengers door"...
Doesn't work on mine Will, tried it loads of times and just won't work on early DE models. Mines a UK 53 plate.
OK mine is an 06 DE, so maybe its just before that.
Gumpy is an 04 / 54 plate.
Wonder if anybody knows when they added this feature to the Zed,
