At some point while walking the plipper must have rubbed against something else and unlocked the car.
If a door on my Skoda isn't opened within 30 seconds of the car being unlocked, it relocks itself. Your theory can only be correct if Hillman's doen't do the same.

The central locking and alarm on my car is like your average supermarket trolley, it seems to have a mind of its own. If one of the doors, usually the rear, isn't properly shut the alarm beeps oddly. I have learned that one. At other times the central locking operates itself for no apparent reason while we are inside , and SWMBO accuses me of clowning when she tries to get out and the alarm sounds. We are both very cautious now.

If it's a VAG model, then central locking problems were quite common on vehicles produced between around 1999 and 2001.
Your local dealership should know how to set up your remote control key to offer various aspects of locking the vehicle (again if it's a VAG model).
My Bora, if unlocked, will relock the vehicle if one of the front doors is not opened within about balf-a-minute. It requires one press of the button to open the driver's door and two to open all of them.
The first setting is a security measure if you are on your own and get into the vehicle - "undesirables" are not given the opportunity to get in using one of the other doors.

PS
It's virtually impossible to "share" a Plip code with any other car owner in your vacinity - one of many, many thousands will be selected each time you use your remote control unit.

Earlier this year I bought a BMW 300-series from auction to sell on. I had it on the driveway for a couple of weeks. I was quite surprised to find that the remote operated the CL on my BMW and also that of my neighbour's 300-series! This happened every time I used the remote. Strangely enough his remote did not operate my car.
I sold the car on, so did not bother to investigate further.

Sorry but I disagree. If that was the case, how come your spare remote key still works after you've not used it for months ?

>>how come your spare remote key still works?>>
I would presume it's to do with the Pin code and the transponder working in tandom.
Done a bit of googling and the nearest situation to your problem was someone whose car battery went flat. After a jump start, using the remote key, the central locking locked, whirred and then unlocked the doors again.
Using both front door buttons to lock the car from inside resulted in success and with the alarm set, but reopening the door and trying to lock from outside brought the original result.
No solution has yet been posted although the thread was only started in the early hours of today.
Incidentally it's been known for thieves who steal a remote car key for a vehicle housed in a large car park, to go around pressing the button until they see its hazard lights flash. Bingo...:-)

Just been looking at my VAG manual regarding remote central locking.
One section that might assist is to do with synchronisation, but it's the reverse of your problem.
It says: "If the vehicle cannot be opened by pressing the radio transmitter button, it could be that the key code no longer matches that of the vehicle's control unit.
"This can occur if the transmitter button is frequently pressed outside the effective range of the system.
"The infrared key must be resynchronised. The synchronisation process must be completed within one minute.
"Press either the open or close button on the key once for approximately one second. The vehicle will remain locked. The control unit, however, recognises a valid code.
"Now lock or unlock your vehicle using the key. The key bite is recognised as the valid mechanical code. A new code is defined between the key and the control unit and synchronisation is complete."

Don't know if this is relevant but I had a Vauhall once that was always unlocked when I got back to it. It had me doubting my sanity. Anyway, to cut a very long story short, it was eventually tracked down to a faulty inertia* switch and once this was replaced, the problem was cured.
*(function of the inertia switch as far as I recall, was to unlock the car should it be involved in an accident when driven with the doors locked)

>>unlock the car should it be involved in an accident>>
Going back to the toe-rags again, this is a feature they use (or have in the past) to steal a chosen parked car - another vehicle is employed to bump it with just enough force to operate the automatic unlocking. Bingo again....

Wouldn't that set off the airbags ?

Unlikely as it takes a fairly heavy impact to set off airbags.
In the course of a former job I came into contact with a very upmarket breakers yard on a regular basis and it was amazing to walk around the stored vehicles and see how bad some of the impacts were and the airbags had not deployed.
The really worrying part was the yard used to sell the undeployed airbags on to back street garage bodyshops!
