It’s very strange as if I press unlock, it does indeed lock after 30 seconds if not entered. I was at work Thursday and a security officer told me my car was unlocked. I was quite shocked because a) I had made sure I locked it, tested the handle, b) how did he know? He said he’s got an older model jazz and tried it to see inside. Now I had walked past the car a couple of times to get into a different building, but I’ve only got the SR model, no keyless entry :'(
